 What They Think of Us at Home. 
 
 Concspojideuce education is a Held tliat is being rapidly filled. All educational 
 branches are being as successfully taught by mail as in the colleges. To many 
 this may be news, but it is not an experiment, as it has been in existence in 
 this country (or the pist twenty years. Our city, which we proudly call the 
 political and educational center of the Nation, has not been behind in this, as 
 the National Correspondence Institute, with its corps of specialists, has been 
 furnishing to the homes of the young men and women instruction which they 
 possibly could never have obtained m any other way.— The Star, Washinc- 
 ton, DC. J J . b 
 
 The National Correspoudence Institute of this city offers a striking e.\;ample of 
 what is being done by correspondence iu an educational line. A few years ago 
 such a thing was almost unheard of, although it had its origin in this country in 
 1873. At first it was confined to courses of reading, and no attempt was made to 
 give iustructiou. Of recent years correspondence schools of law, languages, 
 sciences, business, shorthand, and in fact, the teaching of all subjects of an edu- 
 cational nature, has met with Qattering results, and thousands of young men 
 and women have received an education at home that otherwise would have 
 been beyond their reach.— The Post, Washington, U. C.

 HE QUALIFICATIONS 
 
 For Enrollment : 
 
 The ability to read and write English. 
 For Successful Study : 
 
 The desire to learn. 
 
 WE DO THE KEST by methods that have proved so 
 successful with the thousands who have already had the 
 advantages of the instruction of the National Correspondence Insti- 
 tute, and have gratefully testified to the benefits they have re- 
 ceived from our careful and judicious instruction. 
 
 ARE YOU SATISFIED with your present place ? Would 
 not a knowledge of the principles governing the operations 
 that form your daily work open a way for your future advancement ? 
 You must see plainly that many places of responsibility are beyond 
 your reach merely because you have not had the chance to get the 
 education in scientific and technical matters which those who 
 occupy such places have had. And yet there is very often no dif- 
 ference in natural ability ; in fact, it sometimes happens that the 
 subordinate is the superior in natural gifts, }'et he finds the lack 
 of scientific education a very wall that prevents him from passing 
 on to the higher places. 
 
 'E UNDERTAKE TO BEMOVE THAT BAK- 
 
 KIEK and will educate you, if you are willing to study, 
 so that this lack of knowledge will not prevent your progress to 
 the highest places that your ability and your industry can carry you. 
 
 OUR METHODS are simple and failure is practically im- 
 possible if the student will do his share in careful and 
 honest work. We send him lectures and questions in clear, simple 
 language, accompanied by illustrations and drawings whenever 
 they are necessary to explain the work. The course proceeds 
 gradually, step by step, from the simplest beginnings of Arithmetic 
 to the various technical subjects of each branch. The student is 
 kept supplied with lectures and questions in advance of the work 
 on which he is engaged, to be taken up when he has sent us the 
 answers to the questions on the last lecture he has learned. While 
 we examine his answers, he is engaged upon the work nest in 
 order, which has been previously sent to him. If his answers are 
 satisfactory they are returned to him with the lecture and ques- 
 tions next in order to those on which he has meanwhile been 
 engaged. We comment on his work and point out the matters 
 requiring further attention. If his work is not satisfactory, the 
 faults are pointed out, and complete careful explanations and sug- 
 gestions are given so that the difficulties may be mastered. In 
 such cases new work is not sent until that which is in hand has 
 been thoroughly learned. If the student finds any difficulty in 
 the lectures or questions which he is unable to overcome without 
 assistance, we urge him particularly to submit the trouble to us, 
 and we take great pains to explain the matter, so as to clear away 
 his doubts and difficulties. This we do most cheerfully, for we 
 propose to laave no weak points behind us in our progress with 
 the student. 
 
Department of Engineering. 
 
 Each student is thus A CLASS BY HIMSELF. All expla- 
 nations are directed toward his own ilillii-ultifs, and his time is not 
 taken up in discussing matters which he lully understands, in 
 order to help some otlier student, as must always be the case in 
 class-work. He begins the course whenever it suits him ; he goes 
 through it just as fast as he learns it and no faster. He may finish 
 in less time tlian the averaije, or be may take three times as long. 
 We willingly continue the instrueti«>n until he has 
 learned the whole course. 
 
 The student's work is always ready for him. If he has a few 
 minutes he can sit down to it in his own room, or he can study 
 
 while travelling. In the early morning or late at night, at every 
 minute of the day, his instructor is at his elbow ready to take up 
 the lesson. The hours and sessions of the class, the length of the 
 terms and the vacations all suit themselves to the student's own 
 necessities. His course of instruction proceeds with exactly the 
 speed that he learns it. He will be surprised to find how much 
 can be accomplished by using every minute of his spare time. He 
 will soon come to value most highly the many ten minutes of 
 waiting when nothing else can be done. 
 
 A GENERAL, EDUCATION is an incidental part of the 
 course, for we note the student's faults in spelling, punctu- 
 ation, writing, and use of the English language. No student can 
 complete our course without improvement in his use of lan- 
 guage and great additions to his general knowledge. 
 
 Very often a man, anxious to improve himself, will take up some 
 book upon his daily work. He finds its pages bristling with strange 
 combinations of letters and unfamiliar signs, and soon gives up in 
 despair. We start every student at the very beginning, with or- 
 dinary arithmetic, and in a surprisingly short time those meaning- 
 lees signs become to him as clear and simple as a child's primer. 
 
 No one is too old, no one is too slow, if he is willing to give his 
 spare time and do earnest work with the course, to acquire a thor- 
 ough working knowledge of the profession which he is studying 
 under our care. 
 
 Our courses are intended to give to those who cannot spare the 
 time and money necessary for a college course, and who are willing 
 to work for it, a practical knowledge of a profession, and such thor- 
 ough acquaintance with its scientific principles that he will be 
 prepared to make his way in it, as well as any other person of 
 equal ability and industry. In short, to hring- the College 
 rig-ht into his very home. 
 
National Correspondence Institute, Washington, D. C 
 
 There are many professions in which a workingman, familiar 
 with its practical operations will, with the aid of our course, find 
 himself better equipped for advance than many a college graduate. 
 The man who has worked at the construction of bi'idges, or is an 
 expert in the practical operation of a steam engine, after complet- 
 ing our course in structural engineering, or steam engineering, will 
 be the possessor of a woi'king knowledge that would be the envy 
 of many men highly educated in the theory, but with little knowl- 
 edge of the practical features of his profession. Even where the 
 student is not engaged in work connected with his course our in- 
 striiction qualifies him for the work of his profession. 
 
 This valuable eciuipmeut for the student's life-work 
 
 can l)e aciinived at SMALL EXPENSE and without in- 
 
 terfei'ing' with the student's 
 
 dailjf work. The course costs less 
 
 V, 1 than is required to purchase the 
 
 f.' ' text-books in a college course, for 
 
 no text-book is needed in studying 
 
 by our methods. Our lectures and 
 
 I questions, furnished without extra 
 
 ^ charge, constitute thorough text- 
 
 »T books in every branch. 
 
 To put it entirely within the reach 
 of any one who really desires to im- 
 prove himself, the National Corre- 
 spondence Institute will receive the 
 instruction fee in monthly install- 
 ments of §2 or 1-5 each at a slight 
 advance on the cash price.

 The cost of instruction is so low that anyone who 
 earnestly desires to do the work will And it possible 
 to take a course. WE ARE WILLING TO HELP, 
 IF YOU WILL CONSCIENTIOUSLY DO YOUB 
 PART. 
 
 A description of each course separately is given in 
 the Second Part of this book. There will be found the 
 various subjects taught, and other matters of value to those 
 considering the advisability of taking a course of study. 
 
Department of Engineering. 
 
 In addition to the cost of instruction, as given in the preceding 
 table, the expense to the student comprises only three items ; Cost 
 of paper, postage on matter which he sends to us (we prepay post- 
 age on all matter sent from the Institute), and the materials and 
 instruments required in the work in drawing. 
 
 Cost of paper cannot be accurately stated, but it will average $2 
 to 13 for the course. Postage will average from $2 to $3 for the 
 course. Cost of drawing instruments and materials will be from 
 $8 to $12. Paper, drawing instruments, and material will be fur" 
 nished by the Institute at reasonable prices if desired. 
 
 Envelopes and necessary b'anks are furnished by the Institute 
 without charge. 
 
 If the student, when making his ai)plication is proficient in the 
 preliminary subjects of a course, he will, after passing the exanii. 
 nations necessary to satisfy us of the fact, be permitted to take up the 
 more advanced subjects. But no deduction can be made on this 
 account, as tliere is no saving ofany consequence to us. Seepage 13. 
 
 Failure to pay any installment when due, will interrupt the in- 
 struction of the student, unless satisfactory arrangements have 
 been made in advance, but as soon as he has paid up his arrears 
 he will be permitted to continue, and we will carry on the instruc- 
 tion until he has properh' completed the course. 
 
 If from sickness or other reasonable cause the student is com- 
 pelled to cease work on his course for a time, he will, upon stating 
 his case to the Institute, be permitted to suspend work until such 
 time as he is able to take it up again. 
 
 MoNEV PAID FOR IXSTRUCTION WILL NOT BE REFUNDED IN ANY CASE, 
 
 as we stand ready to carry out our part of the agreement and furnish 
 the instruction. But the student may transfer his right to instruc- 
 tion to another person on the payment of a fee of ^l if the latter is 
 capable of continuing from the point where the former left off. 
 
 But if it is found necessary to review any part of the work with 
 the new student, a moderate charge will be made for such extra in- 
 struction. 
 
 OUR INSTRUCTORS are all experts in the branches they 
 teach ; they have all had extensive experience in their lines 
 of instruction and are familiar with all the practical and theoreti- 
 cal features of the courses they conduct. Examine the list on page 
 5 and you will see that they have all occupied responsible positions 
 in one branch or another of Engi- 
 neering Work. They are prepared 
 to aid you in acquiring the subjects / 
 
 by every efibrt in their power, and 
 with all the resources of a complete 
 acquaintance with the principles 
 and practice of the professions you 
 are trying to learn. We want every 
 student when he has finished his 
 course to be thoroughly taught in 
 the branches he has taken. For 
 that will do us more good than to 
 turn out twi(« as many who are but 
 half-instructed. 
 
 We rely upon the results 
 of the iiistriiction we give 
 our stiideiits tor our most 
 effective atlvertiseineiit. 
 
 At the end of the work a thorough 
 examination must be passed to obtain the Certificate which is 
 awarded for proficiency in the course which has been pursued.

 Course in Higher Surveying. 
 
 HE foundation for the study of tliis 
 course is mathematics, and in this 
 subject we give thorough instruction 
 covering all the matters necessary to 
 an understanding of the operations 
 and computations of surveying. The 
 surveyor must also be a draughtsman, 
 and our course will give him a valu- 
 able training in the different classes of 
 work which a surveyor is called upon 
 to do. This part of the course not 
 only fits him for the drawing necessary for the surveyor, but also 
 gives him a considerable acquaintance with the general principles 
 of mechanical drawing. 
 
 The study of Surveying itself will cover the methods in common 
 use, from those emjiloyed in the simple surveymgof farm boundaries 
 to the more exact and complicated methods of railroad, mining 
 and hydrographic surveying. The modes of keeping field-notes 
 for the different classes of work will be thoroughly discussed, and 
 
 the student will receive valuable information on this subject, one 
 that is seldom treated as its importance deserves. 
 
 The methods of platting and computing the results of the differ- 
 ent kinds of surveys will be fully and carefully explained. 
 
 The student will be made acquainted with the methods of map- 
 ping considerable areas ; that is topographic surveying and draw- 
 ing, including a discussion of triangulation, stadia work, and the 
 determination of heights. 
 
 Exercises in surveying without the use of the ordinary instru- 
 ments will be given, and the student will have an opportunity to 
 become familiar with and apply in practice many methods and 
 operations of actual field and office work. 
 
 This course presents a favorable opportunity for surveyors' assist- 
 ants, such as rodmen, chainmen, etc., who wish to advance them- 
 selves in the profession of surveying by learning the subject 
 properly, instead of picking it up haphazard by experience. The 
 latter method produces the many incompetent surveyors we find 
 everywhere, who are able to do a few things, those they have 
 seen others do ; but are hopelessly lost when confronted by some

 unusual condition or are called upon to do some work, simple 
 enough in principle, but new to them. By our thorough and 
 systematic instruction the student can learn the whole subject, and 
 be ready to apply his knowledge to meet every new problem that 
 arises in his work. 
 
 Working with a competent surveyor may give good results ; but 
 more often it does not. For the surveyor seldom has the time or 
 the inclination to give the necessary instruction, while it often 
 happens that he does not have the knack to impart his information 
 in such a systematic way as to do any good to the learnei'. 
 
 There are many professional draftsmen who need a course in 
 surveying to enable them to properly perform the work of platting 
 field notes which they are called upon to do from time to time. 
 
 -- There are manj' others who have a 
 
 great desire to become surveyors, but 
 cannot give up their present employ- 
 ment to study in a college. To such 
 ^^ persons our course offers the very 
 
 '^ M. 
 
 chance they need to attain the knowl- 
 edge of their chosen profession.

 The course in Higher Surveying is 
 added so that the student may obtain 
 a knowledge of the most accurate 
 methods, such as are used in the opera- 
 tions of the U. S. Coast and Geodetic 
 Survey and the U. S. Geological Sur- 
 
 ■^- ■" vey. In this course will be taken up 
 
 the various branches of Geodetic Sur- 
 
 ,', that 1'-, surveying in which the true spheroidal shape of the 
 
 is taken into consideration. 
 
 While the surveyor is not often required to do work of this 
 kind outside of the Government surveys, yet a knowledge of it is 
 often a matter of great importance to him. The accuracy of his own 
 work may frequently depend upon his thorough understanding of 
 the methods used in this higher class of work ; as, for instance, 
 when it becomes necessary for him to use the results obtained 
 by it. 
 
 The importance and in fact the necessity of this higher course 
 for the proper rounding out of the surveyor's knowledge of his 
 profession can be judged from the following synopsis : 
 
 Measurement of base lines, observation of angles for primary 
 and secondary triangulation, observations for determining latitude 
 and longitude, with sufficient instruction in Astronomy to enable 
 the student to understand the methods employed, and the compu- 
 tation and adjustment of geodetic observations. 
 
 Further instruction is given in the methods of surveying as 
 applied to these more extensive operations, with instruction in the 
 use of the plane table, and the methods of precise levelling.

 Course in Railroad Engineering. 
 
 HE railroads have an important part in tlie de- 
 velopment of our country, and the work of 
 constructing railroads continues through all 
 periods, whether of good times or had. The 
 building of railroads within our cities, and 
 from one to another for the development of the 
 country lying between them, has created a con- 
 siderable demand for railroad engioeers in the 
 East, while the development of the newer country of the West has 
 added to the demand, so that the future of railroad engineering is 
 most promising. 
 
 Many of the larger railroad companies employ from fifty to five 
 hundred men in their engineering departments, and in most of 
 them, notably the great Pennsylvania Railroad Company, promotion 
 from the lowest grades to the highest is based entirely upon the 
 industry and ability of the employe. It is a great encouragement 
 to railroad engineers to know that the late President of this com- 
 pany began in its service as a rod man, and gradually worked his 
 way upward through the engineering force, till at last his ability 
 placed him in the pi'esidency ; and this instance does not stand 
 alone, for in all companies the Engineering department is one of 
 the most important, and many of the highest offices are filled from 
 that branch of the force. 
 
 Our course in Eailroad Engineering will give the student a sound 
 foundation for the technical work of the profession, and will render 
 him capable of entering upon the practical duties of railroad 
 engineering. 
 
 Mathematics. — In this subject the student will begin with 
 arithmetic, and continue with algebra, geometry and trigo- 
 nometry making a course in mathematics which will qualify him 
 to thoroughly understand the computations generally required of 
 the railroad engineer. 
 
 Mechanics. —The student will take a thorough course in ele- 
 mentary mechanics and physics in which he will be carried far 
 enough to take up l;he special subjects of railroad construction 
 which are based on these studies. 
 
 Drawing'. — The work in drawing will cover preliminary instruc- 
 tion in the general principles of mechanical drawing, followed by 
 instruction and exercises relating specially to railroading. 
 
 The student will then take up the subject of Railroad Engi- 
 neering' itself, going thoroughly over its various branches ; start- 
 ing with the preliminary office work and passing through the 
 entire location, construction and equipment of a railroad ; giving 
 also some attention to the important questions of maintenance.

 Course in Electrical Kno-ineerinQ^. 
 
 HERE is a constantly increasing demand for men 
 skilled in designing, constructing, installing, test- 
 ing, and operating electrical machinery of every 
 conceivable nature, and as the demand increases 
 there is not an equal increase in the supply of 
 skilled labor. The reasons are obvious. Many 
 would fit themselves for holding these positions 
 were it not that their business will not permit 
 them to leave their homes or they are linancially 
 unable to take such a course in institutions established to teach by 
 personal attendance. 
 
 Those who fit themselves by the correspondence method for the 
 electrical profession, will find without much difficulty some opening 
 either as Wiremen, Foremen, Contractors, Linemen, Motormen, 
 Central Station Superintendents or Constructing Engineers, where 
 they all may obtain a foothold; which, while it may be small from 
 a remunerative standpoint at the beginning, is sure to develop in the 
 future into some position of a far more satisfactory character than 
 could be held by any one not versed in the science of electricity. 
 
 Those who are now employed in electrical establishments should 
 be well acquainted with the principles underlying the construction 
 of the machines which they may handle. By studying an infinite 
 number of books one might eventually find the information he 
 sought, but in our method of instruction no books are necessary, 
 our instruction papers giving in a clear and comprehensive manner 
 a thorough explanation of the principles of all apparatus of an 
 electrical nature, whether it be the simplest electric bell or the 
 most complicated alternating current dynamo. 
 
 No education is complete to-day without an understanding of 
 electricity and this can only be obtained by careful instruction 
 under the direction of those who have spent years in studying the 
 principles involved in electricity and magnetism, and are thus com- 
 petent to direct the study of one who seeks an education iu this 
 science. 
 
 There are men in the electrical business to-day who are no 
 farther advanced than they were ten years ago, whose daily round 
 of duties never takes them out of the old route, and the marvelous 
 strides made in electricity in the past few years are almost entirely 
 unknown to them. Unless these persons avail themselves of the 
 opportunities for advancement along electrical lines, they will be 
 in the same position ten years hence that they are now. Dynamo 
 Tenders, Wiremen, Engineers, Mechanics, men from every position 
 in life, young and old, can alike avail themselves of these advan- 
 tages on the plan we offer. The Dynamo Tender may become a 
 Central Station Manager, the Motorman a Railway Superintendent, 
 the Lineman a Testing Chief, the VVireman a Constructing Engi- 
 neer, and one and all become practical intelligent Electrical Engi- 
 neers by carefully following the course as mapped out by this 
 Institution. 
 
 The foundation for the work of the course is laid by careful 
 preliminary instruction in Mathemetics, Mechanics and Mechanical 
 Drawing. 
 
 After this we give the student a course of instruction calculated 
 to lay a foundation in the first principles of Mag'netism ; for with- 
 out magnetism, the lighting of our cities, electric propulsion of our 
 
Department of Engineering. 
 
 17 
 
 railways and the direction of our ships' courses would alike be an 
 impossiliility. 
 
 After dwelling at some leagtli upon the laws of natural magnets 
 magnetic induction, various laws of attraction and repulsion, 
 etc., we take up Sources of Electricity, pointing out their nature 
 and properties. Under this head a thorough explanation of the 
 modern accepted theories is given, and the student is next 
 instructed in the class of phenomena embraced under Static Elec- 
 tricity. Here the difference between 
 conductors and insulators, the mean- 
 ing of certain electrical terms, the 
 action of electrified bodies upon each 
 other, an explanation of the various 
 electro-static machines, properties of 
 atmospheric electricity and the value 
 of lightning rods are thoroughly ex 
 plained. 
 
 Current Electricity is next dis- 
 cussed in a very thorough manner, 
 showing the difference existing be- 
 tween electrical currents and electrical 
 charges ; what constitutes an electrical 
 circuit ; different types of batteries, 
 such as: LeClanche, Gravity, Daniell, 
 Bunsen and Edison. 
 
 A complete and comprehensive series of lessons is also given 
 upon the Storage Battery commencing at the time of its incep- 
 tion and gradually leading up to the most improved and perfected 
 apparatus in use to-day. 
 
 Ohm's Law, which governs the operation of all electric circuits 
 and without a knowledge of which no one can intelligently con- 
 
 struct or install electrical apparatus of any character, is thoroughly 
 dealt with in all its various forms. 
 
 Electro-Metallurgy is treated in a simple manner and the 
 various methods employed, salts used, solutions and different types 
 of currentforelectro-platingand electrotypingare clearly explained. 
 
 Under Electro-Mag'netisin the relation existing between 
 magnets and electrical currents is clearly pointed out, and the 
 action of currents on each other and upon iron, the calculation of 
 magnetic circuits, and the determination of the lifting power of 
 magnets are thoroughly dealt with. 
 
 The subject of Electric Bells is taken up and various types of 
 annunciators, alarms, clock devices, automatic, pendant and static 
 gas-lighting apparatus are dealt with. The complex methods of 
 wiring for these various devices and ingenious combinations to pro- 
 duce the desired results in the most satisfactory manner are given. 
 Our instruction in Electrical Units and Definition.s is suffi- 
 cient to enable a man to intelligently use all of the technical terms 
 and definitions that are involved in the electrical profession to-day 
 for practical work. 
 
 We devote considerable time to Electrical Measurements, point- 
 ing out the different types of Galvanometers, Voltmeters, Aiu 
 meters and Wattmeters, with detailed explanation of their parts, 
 and then take up a series of measiu'ements with the Wheatstone 
 Bridge, calculated to enable any one to use this valuable piece of 
 apparatus intelligently in making simple or elaborate tests. 
 
 The subject of Dyuaiuos is very carefully treated. The 
 principles of operation and the essential parts ai'e first pointed out 
 and then an explanation of the various details is given. Following 
 upon this the rectification of current by commutator, methods of 
 exciting the fields, the difi'erent types of armatures, the various 
 methods of winding, the losses that are met with, lamination of 
 core, resistance of ttie air gap, the distortion of field, the Many 
 
iS 
 
 National Correspondence Institute, Washington, D. C. 
 
 Causes of Sparking at the Brushes and the Remedies, rheostats and 
 various forms of regulators, series, shunt and compound wound 
 machines, the theory of alternating currents, the construction and 
 operation of commercial alternators, the most approved methods 
 concerning care, operation and maintenance of dynamo-electric 
 machinery. Dynamo Calculation and Design, all of these subjects 
 are treated with the greatest care in a manner at once so simple 
 that the most obtuse can understand and yet so complete that the 
 most advanced or exacting can find nothing omitted. 
 
 Under Electric Motors the student will obtain a knowledge 
 of the first early types of motors, the principles upon which they 
 operate, the methods of regulation, system of connection, manner 
 of starting, how the}' are wound and the distinctive features as 
 compared with dynamos and their adaptability to various require- 
 ments. Diagrams accompanying this instruction are of such a 
 nature that the student would have but little difficulty in connect- 
 ing up any make of motor that might come under his notice. 
 
 Transformers and Induction Coils are treated with a special view 
 to their use on alternating current circuits, the methods of construc- 
 tion and the principles of operation being clearly pointed out. 
 
 Incandescent and Arc Lamps are thoroughly explained, special 
 attention being given to the latest types, the latest improvements 
 in both kinds in use by the electrical world to-day. 
 
 Transmission of Power is discussed thoroughly and all the 
 various wiring tables and formulas for calculating the sizes of 
 wii'es for different purposes in transmitting electricity are given. 
 
 In pointing out the principles of Electric Railwaj's a 
 thorough explanation of the various over-head, under ground and 
 surface systems are given, and the different types of motors, gen- 
 erators and appliances made clear. 
 
 " Central Stations " is a subject which is entered into at 
 some length in order that the student may not only understand all 
 
 the connections and the operation of the various appliances therein , 
 but may be able to successfully care for a generator, and design, 
 construct and repair any piece of apparatus which may become 
 injured. 
 
 The Operation of Telephone and Telegraph Appai'atus is thor-

 Course in Structural Enmneerinor. 
 
 A 
 
 STRUCTURAL engineer, in the bi'oad sense of 
 the term, is one wlio understands and Isnows 
 liow to control the forces of nature, so far as 
 they affect structures, by making his designs 
 accord with scientific principles. In preparing 
 our course of lectures on Structural Engineering 
 we have kept this definition in mind, and have 
 endeavored to present this subject to the student 
 in its most attractive form ; to bring out in bold 
 relief the jirimary principles, and to aid the student to reason 
 pr.K-tically and with system, without losing himself in a mist of 
 mathematical formulas. In other words, the student is drilled 
 in facts and principles, and taught to use his knowledge so as to 
 arrive at practical results. 
 
 In planning a structure, the designer must consider many things, — 
 the best and most economical arrangement of its parts to meet 
 the specified requirements, the methods of joining the parts together 
 and the material to be used. He must have the structure strong 
 enough, at the same time must not go to the expense of using more 
 material than is necessary. Especially is it important in planning 
 large structures of steel, that the designer should know what 
 character of trusses to use, how to estimate the strain on each com- 
 ponent part and the best methods of making joints. In fact since 
 steel has been used to such a large extent as a structural material, 
 it has becouie evident to all engaged in building operations that a 
 technical knowledge of the principles of engineering is essential to 
 him who hopes to succeed and keep abreast of his profession. 
 
 Therefore this course is recommended to men who are in the archi- 
 tectural, engineering, and building professions, either as a review, 
 or for the purpose of gaining a further acquaintance with the scien- 
 tific side of their professions. It will also be an advantage to 
 students who propose to continue the subject at college or by pri- 
 vate study ; while to tlie ambitious young men who are engaged in 
 this line of business, or to others who desire to qualify themselves 
 to enter upon it, this course offers a most favorable opportunity. 
 
 We begin with a thorough drill in matliematics, elementary 
 mechanics aud physics. In mastering the work given him in 
 these subjects the student becomes acquainted with the founda- 
 tion principles of the profession, and is taught how to use them. 
 Instruction in drawing follows, through which the student will be 
 qualified to make plans and detailed drawings for structural 
 work. 
 
 Analysis of Framed Structures— Under this head are in- 
 cluded the graphical and analytical methods of determining 
 the beading moments and shearing forces in loaded beams, and 
 the principles and methods of determining the stresses in the sep- 
 arate members of trusses. By studying the graphical and analyti- 
 cal methods in conjunction with each other the student will 
 find that the one method aids him in understanding the other, 
 and he will learn to decide in what cases each method is to be 
 preferred. 
 
 Streng'th of Material. — Physical characteristics of iron and 
 steel, brick, stone and timber. Determinations of center of

 gravity, moments of ineitia and radii of gyration. Methods 
 of designing beams, girders and columns. Designing riveted 
 joints. These subjects will receive careful treatment, vt-ill be 
 made clear to the student, and will be dealt with in the most 
 practical way. 
 
 Design of Structui es.— Under 
 this head we deal with the deter- 
 mination of stresses in the different 
 types of roof and bridge trusses, 
 and the relative merits of the var- 
 ious kinds in general use ; with 
 the treatment for uniform and 
 concentrated load systems ; with 
 the effect of wind on structures, 
 with tlie designing of columns 
 and the merits of the different 
 forms of steel columns; and with 
 the use of steel in fire-proof build- 
 ings. 
 'i ,~. ,; Bridges. — This subject, one of 
 
 ('?''' the most important of the course, 
 
 will include a thorough discussion 
 of the principles involved in the 
 ' \ ^ 1 ' designing of bridges of wood, 
 
 masonry, and steel ; with a study of 
 standard examples of each class, and practical instruction in de- 
 signing structures of each kind. 
 
 Estimates, Specifications, Siiperiutendeiice and In- 
 spection. — Under these heads will come a discussion of the 
 methods of preparing estimates and specifications ; of the duties of 
 the superintendent of construction and his relation to contractors ; 
 
 and of the inspection of matei'ial and work, and the determination 
 of the character of material and the quality of work. 
 
 The practical problems in this course will include the complete 
 design of a steel roof ti'uss, a plate girder bridge, and a railroad 
 truss bridge with computations and detail drawings.

 Course in Hydraulic Engineering. 
 
 UR course is designed to give the student a 
 good working linowledge of the principles 
 and theories necessary for an intelligent solu- 
 tion of everyday problems in hydraulics and 
 kindred subjects ; as for instance, the selec- 
 tion of suitable sources of water-supply, cal- 
 culation of probable rain-fall and ' run-oif" 
 and the design of dams, reservoirs and dis- 
 tribution systems; the design, erection and 
 test of hydraulic motors, pumps and other 
 machinery ; the improvement of rivers and 
 harbors, the design of canals, locks, flumes and 
 irrigaticin systems; in fact, all manner of problems involving 
 the use or control of water for the benefit of mankind. 
 
 To pursue these subjects intelligently, a good working knowledge 
 of arithmetic, elementary algebra, geometry and trigonometry is 
 absolutely necessary ; and these subjects together with mechanical 
 drawing, surveying, a study of the strength of materials, elemen- 
 tary mechanics and theoretical hydraulics are taken up as a pre- 
 liminary to, and a preparation for, the consideration of the subjects 
 relating more particularly to hydraulic engineering. The use of 
 steam and air as mechanical agents it also treated in the prelimin- 
 ary course. 
 
 Having mastered this preparatory work the student reaches what 
 will prove, no doubt, the most interesting part of the course. 
 
 The first subject considered under the head of applied hydraulics 
 is the design and construction of new, and the improvement of 
 existing, water-works systems, a matter of vast and constantly 
 
 growing importance. Following is a lirief outline of the order in 
 which the several bran(4ies will be taken up : A consideration of 
 the quantity of water required, based chiefly on statistics of actual 
 consumption in cities and towns in different parts of the country ; 
 the conditions governing the selection of a suitable waterslred and 
 the methods used in arriving at a safe estimate of the amount of 
 rain-lall and the proportion of this amount which may be expected 
 to reach the reservoirs ; the design and construction of dams, 
 reservoir embankments, settling and storage basins, conduits and 
 distribution systems ; filtration and tlie pumping of water to 
 higher levels. The subject of pumps will be considered here only 
 in a general way, being taken up in detail under the Iiead of 
 liydraulic machinery. 
 
 llydraillic Motoi's. — After a brief consideration of the 
 principles governing the construction of the old-fashioned over-shot, 
 under-shot, and breast wheels, the use of which is still advisable 
 under certain conditions, we reach the subject of turbines, by far the 
 most important of the hydraulic motors. The principal types of 
 existing turbines will be described fully, and particular attention 
 will be given to the principles governing their action as well as to 
 the details of erection and the methods of conducting tests for the 
 determination of capacity and eflflciency. 
 
 In this connection will be described in detail the design and con- 
 struction of head-gates, flumes, gratings, penstocks, draft tubes and 
 tail race, with explicit practical directions for the construction and 
 use of dynamometers for measuring the power actually delivered, 
 and for the design and manipulation of hook-gauge, weir, etc., for 
 ■ determining the amount of water used, and so computing the efli- 
 
22 
 
 National Correspondence Institute, Washington, D. C. 
 
 ciency of the machine. Impulse wheels will also receive careful 
 attention, and the principles governing their design and usefully 
 explained. Motors of the Three-cylinder or Brotherhood type will 
 he considered under the head of hydraulic machinery. Among 
 the motors will be included meters for the measurement of water ; 
 for these, while not used for the generation of power, are none the 
 less prime-movers. Here again much space will be given to direc- 
 tions for practical tests and installations. 
 
 Hydraiilio Machin- 
 ery — Punip.s. — After a 
 brief review of so much 
 of theoretical hydraulics 
 as may be directly appli- 
 cable to pump design, the 
 study of pump detail will 
 be taken up, illustrations 
 being drawn from the 
 ^ * best examples of modern 
 
 / construction ; among the 
 
 ; types considered ai-e hy- 
 
 draulic-pressure pumps, 
 direct-acting duplex, di- 
 ^ rect-acting compound and 
 
 triple-expansion fire pumps, rotary and centrifugal pumps, etc. 
 A special chapter is also devoted to the standard methods of con- 
 ducting duty trials of pumping engines. 
 
 Other hydi-aulic apparatus, of which lack of space here prevents 
 more than the briefest mention, are ; accumulators, presses, ele- 
 vators, cranes, jacks, riveters, forging presses, etc., an almost end- 
 less list, extending into every branch of mechanical industry, and 
 offering a limitless field for the exercise of mechanical industry and 
 skill. 
 
 Steam Eng-ines and Boilers. —Having already considered 
 the theories relating to the generation of steam for use as a mechan- 
 ical agent, this division will be devoted to a discussion of the 
 different types of boilers and engines, and the factors affecting their 
 strength and efficiency. The use of the steam engine indicator for 
 setting valves, and for determining the horse-power and steam con- 
 sumption of the engine, will receive the fullest consideration, 
 as will also the standard methods of boiler and engine tests as 
 recommended by the American Society of Mechanical Engineers. 
 The whole subject will be treated from the point of view of the 
 hydraulic engineer, who, while not expected to engage in the 
 design of steam engines, should have a sufficient theoretical and 
 practical knowledge of the subject to enable him to choose, test 
 and use to the best advantage the machines adapted to his needs. 
 
 Kivers, Harbors, Canal, etc.— Under this heading will be con- 
 sidered the methods pursued in deepening river channels, by dredg- 
 ing, rock e.xcavation and contraction of flow ; the protection of 
 caving banks by the use of- mattresses, rip-rap, spur-dams and 
 dykes; the design of ice harbors; construction of breakwaters and 
 piers ; the building of canal embankments and locks ; and many 
 other problems relating to the control of water for the uses of 
 navigation. 
 
 Irrigation Engineering'. — This subject, while having much 
 in common with water supply, has also many features peculiar to 
 itself, as for instance, the, design and construction of regulators., 
 measuring weirs and timber flumes ; the design of distributaries, 
 methods of applying water to the land, etc., all of which will be 
 considered in their proper place. Attention will also be given to 
 the laws and regulations of the Government concerning the subject 
 of irrigation, with which the irrigation engineer should be 
 . acquainted.

 Course m Sanitary Engineering. 
 
 HE work of the Sanitary Engineer may be 
 broadly defined as having for its object the 
 improvement of the public health by sup- 
 plying pure water and fresh air to our houses 
 and the removal from them of all injurious 
 wastes. 
 
 As soon as the progress of civilization 
 tended to the concentration of population 
 within areas of limited extent, it became 
 necessary to make provision for the removal 
 of noxious refuse from the vicinity of habi- 
 tations. The importance of sanitary works was early recognized, 
 a fact well attested to this day by the ruins of the aqueducts and 
 sewers of ancient Rome. It is, however, within the last sixty years 
 that sanitary science has clearly demonstrated the dangers to 
 human life which exist in a vitiated atmosphere, a polluted soil or 
 an infected water sup('ly. 
 
 What more interesting and vital problems can be solved by the 
 trained engineer than those presented in intelligently designing 
 and skillfully constructing in our cities and dwellings suitable 
 means for decreasing or removing the harmful effects of these un- 
 seen agents ? 
 
 The preliminary portion of our course includes thorough train- 
 ing in fundamental mathematics and mechanics as needful prepar- 
 ation for the further studies of the special course. These are fol- 
 lowed by a concise discussion of the air we breathe and the soil on 
 which we tread, treating briefly of the composition of air, its more 
 common iurpurities and ihe resultant deleterious efiects. Also of 
 
 the simpler characteristics of the virgin soil, how it becomes 
 infected, and the serious and enduring eifects of its pol- 
 lution. 
 
 The subject of Water Supply, next taken up, considers among 
 other topics, the character and capacity of water-sheds, the quantity 
 of water required for the supply of cities and towns, the impurities 
 to which water is liable, methods of purification and aeration, as 
 well as its storage and distribution through pressure or gravity 
 systems. 
 
 As a natural sequence to the subjert of water supply we pass to 
 studies bearing on the removal and treatment of the liquid wastes. 
 Under the heads of Sewerag-«, Drainag-e and Sewage Dis- 
 posal, attention is first given to general problems, as the comparison 
 of the water carriage system with other methods of disposal, the 
 application of the separate system of sewers, the size of storm 
 water conduits, formulas for computing discharges, and the im- 
 portant methods of sewage treatment, after which the student is 
 brought to consider the construction of various detailed types of 
 work and their care and maintenance. 
 
 The teaching of these matters will be from the practical stand- 
 j^oint, looking to results to be attained rather than the discussion 
 of impracticable theories. 
 
 There will next be taken up House Plumbing- and Drain- 
 age, combining instruction in the practical design ofinternal piping 
 systems for the removal of the liquid household wastes with a 
 connected review of the best American practice as to ventilation 
 and fixtures. There will also be given, as an allied subject, a 
 succinct course in house distribution systems for gas-iighting, com-

 prising the desij;n ami practiral ponstruction of lines of piping for 
 this purpose. 
 
 The subject of Heatiuy and Ventilation, wliich has so much 
 to do with the health and comfort of every conimunitv, will be 
 treated systematically, teaching first the general principles on which 
 sound design is based, then taking in order the diflerent systems of 
 heating by steam, hot water and hot air, each combined with ade- 
 quate ventilation, followed by 
 studying the conditions and class 
 H of Ijuildings for which each system 
 
 is best suited. 
 -— -«, Under the general topic of Vil- 
 
 lage and City Sanitation, at- 
 . i tention will be devoted to a study 
 ^ I of the collection and treatment of 
 those lefs noticeable wastes such 
 as garbage, builder's rubbish, and 
 street refuse, which it is desirable 
 to remove from the immediate lo- 
 I cality of our dwellings. 
 
 In addition, the location and 
 construction of cesspools and pi ivy 
 vaults, and the removal of surface 
 and ground water will be examined. 
 
 Tlie work of this course is carefully planned in its several 
 branches so as to render it attractive and profitable alike to the 
 foreman or skilled mechanic, to the rodman and chainman in a 
 field party, to the college graduate desirous of obtaining a further 
 training in technical lines, and to the experienced engineer em- 
 ployed, perhaps with low compensation, in some overcrowded 
 branch of the profession. To each of these we offer a ready means 
 of instruction, at a price within his reach and in time at his own 
 
 disposal, in a working knowledge of one of the most alluring and 
 growing branches of engineering science.

 Course in Municipal Engineering. 
 
 HE demand for the services of the engineer in 
 most localities may be justly said to be depen- 
 dent upon the concentration of population 
 which has taken place in those localities. 
 
 But slight need is felt for the trained en- 
 gineer in a sparsely settled rural community, 
 demanding inferior means of communication 
 only, having fords at its stream crossings, liv- 
 ing in simple dwellings, depending upon springs 
 and wells for its supply of water and requiring only nature as its 
 scavenger. 
 
 When such a community becomes a village or town, it proceeds 
 to construct improved highways, provided with bridges and cul- 
 verts, and possibly a surface railroad. Its sanitary needs are met 
 by building simple systems of water-mains and sewers and the in- 
 troduction, to the homes of the well-to-do, of house plumbing. All 
 these improvements, if well planned and economically carried out, 
 call for the skill of the Ci vil Engineer. 
 
 If now, this typical hamlet, favored by the smiles of Fortune, ex- 
 pands into a city, its need of the engineer is greatly increased. We 
 now find well-paved^ streets, marked by a radiating network of 
 street railways, and underlaid by an honeycomb of mains and con- 
 duits. The valleys are spanned by massive viaducts, which stretch 
 for miles above our heads, to end at last in mammoth stations. 
 The lofty buildings, seen on every hand, rival the Tower of Babel 
 in height, and almost cut oif sun and sky, a loss hardly noted, so 
 used are we to seeing the night illumined like the day. 
 This transformation of farm lands into the sites of thriving towns 
 
 and even of cities has occurred in many instances within the 
 memories of a single generation. That such changes will continue, 
 necessitating the employment of thousands of engineers and the 
 expenditure of additional millions of dollars, is the fixed belief of 
 all close observei's of the progress of civilization on our continent. 
 
 The reflex influence of the concentrated activities found in met- 
 ropolitan centers is also beginning to be manifested in suburban 
 districts in the current agitation for improved roads, in the promo- 
 tion of rapid transit, the extension of sanitary control, and the ap- 
 plication of scientific methods for bettering the conditions of vil- 
 lage and town life. 
 
 The intelligent direction of these potent forces of development 
 and extension will require and engage all who have anticipated 
 the call for such services and made due preparation for rendering 
 them. The opportunities offered by this course will enable many 
 to acquire the necessary knowledge who could not otherwise, by 
 reason of the limitations of time and cost, hope to do so. 
 
 Our course of Municipal Engineering' will, at the outset, 
 prepare the student by the pursuit of the required preliminary 
 studies to profitably undertake the advanced and technical portion 
 of the work. He will then be taught the theory and practice 
 of the important branches of civil engineering as applied to city 
 works. 
 
 The first technical topic — Water Supply, Storage, and 
 Distribution — will he mainl}' concerned with the considera- 
 tion of the amounts of water required for cities, the collection of 
 a supply, its quality, its storage, and its distribution to meet speci- 
 fied conditions of use.

 This will be followed by the subjects of Drainag'e, Sewerage 
 and Sewage Disposal, in the discussion of which general 
 principles controlling the quantities of rainfall and sewage, the type 
 of system most desirable, and the size of conduits, etc., will first be 
 laid down, to be later succeeded by detailed statements of methods 
 of construction and examples of efficient completed works. The 
 chapters on Sewage Disposal will be devoted to the principal 
 means and apparatus used for 
 purification with special attention 
 to results attained in this country. 
 Under the head of Streets and 
 . _^ Pavements the important prob- 
 
 ^- ^, V'' lems involving the relation of topo- 
 
 *^^ '" \ graphy to the lines, grades and 
 
 I/4BI tTW' % I cross-sections of streets will be 
 
 taken up. The treatment of pave- 
 ment foundations and the laying 
 and maintenance of the most sat- 
 isfactorj' and durable surfaces will 
 ije studied, in coLnection with 
 illustrative examples suited to the 
 subject. 
 Consideration will then be directed to the principal types of 
 Street Railways including cable lines, the elevated and under- 
 ground trolley, compressed air motors, and track and conduit 
 design and building. 
 
 The subject of Pnblic Lighting' will develop the application of 
 naphtha, gas and electric systems of lighting to roads and parks. 
 
 The course will conclude with a study of Municipal Or- 
 ganization, Assessniejits and Franchises. Much interest 
 is manifested, at the present time, in the administrative methods 
 
 >f J?:^ 
 
 of city government and in the important questions respecting the 
 distribution of taxation and the control of the large entei'prises 
 incident to city growth. The discussion of these matters will 
 be practical, and highly valuable to all thoughtful students.

 UR industrial organizations are each year demand- 
 ing men of higher education for employees. 
 The knowledge that was our father's is no 
 longer sufficient. The intelligent mechanic must 
 . know more than simply how to place a piece 
 of work in the lathe or planer, or how to place 
 the pattern when making the mold. The man 
 who knows only that is a mere tool, like the 
 lathe or planer which he operates, and like 
 them also he will never become any thing else_ 
 It is the men of intelligence and learning who are chosen for the 
 desirable positions. No man is fitted to be foreman or super- 
 intendent of a shop who does not know the principles of mechanics, 
 strength of materials, and machine design. 
 
 But if he know-s these subjects he can correct errors and 
 suggest improvements in the designs. Such a man will be chosen 
 as designer, and his knowledge of drawing and kinematics will 
 then enable him to design machinery by the modern methods, with- 
 out the expense of experimenting on two or three botch machines. 
 The foreman should understand the principles of the construc- 
 tion and operation of all kinds of machinery. He must be able to 
 calculate what forces act in any one piece of the machine, how to 
 properly design that piece to resist those forces, and how the forces 
 are transmitted from one piece to another. 
 
 Mechanics, as a rule, ai'e men of ambition and nat\iral intelli- 
 gence, but many of them not having had the advantage of a 
 mechanical education, find themselves at a great disadvantage in 
 the close competition of our present day. They realize if they 
 
 could but obtain a technical education they could win prominence 
 Many of the best Mechanical Engineers of the present day are 
 those who studied Mechanical Engineering after they had learned 
 their trade. 
 
 It is the purpose of the Institute to provide such men with the 
 opportunity they have so long desired. The door is open to any 
 one who will study the course in Mechanical Engineering. In 
 order, however, that the student may be able to easily understand 
 all the technical subjects, it is necessary for him first to master the 
 preliminary subjects of Mathematics, Physics, and Mechanical 
 Drawing. 
 
 The student need only know how to read and write in order to 
 take this course, as he is started at the very beginning of Arith- 
 metic. He is given thorough instruction in all the rudiments of 
 the subject, including all the operations ordinarily required. Al- 
 gebra, Geometry and Trigonometry are treated in very much the 
 same way. Great care is taken to give only that which is of most 
 practical use, and yet give an adequate and comprehensive idea of 
 the subject. In Algebra, the student is taught to solve intricate 
 problems by the use of symbols. In Geometry, he is taught the 
 forms and proportions of plane figures, and the measurements of 
 areas, angles, etc. In Trigonometry, he is tauglit the solution of 
 the triangle and the use of trigonometric and logarithmic tables. 
 
 No one can hope to learn to design machinery who does not have 
 a thorough knowledge of Mechanical Drawing'. Therefore 
 considerable importance is given to this part of the course. After 
 being taught the general principles, the student will make working 
 drawings of various machine parts from sketches and dimensions.

 The course in Pliysics begins with elementary mechanics, and 
 talies up in succession hydrodynamics, pneuniatics. and heat. Tlie 
 course throufrhout is ilhistrated and explained by simple experi- 
 ments with which the student is already familiar, or which he can 
 easily perform with the simplest home-made apparatus. After a 
 preliminary study of the properties of matter, the laws of motion 
 are given aud illustrated. The composition and resolution of 
 forces are studied, and woi'k aud energy are explained. 
 
 Hydn dynamics treats of the action 
 of forces and motion in liquids. The 
 study of the forces when they are bal- 
 anced, and the ^liquid is not in motion, 
 ~j- is called Hydrostatics. Hydrokinetics 
 
 , Ar deals with the energy of liquids in 
 
 motion. The theory of rams, water, 
 wheels and turbines is fully explained. 
 
 The laws governing the action of gases 
 are studied under the head of Pneu- 
 matics. The application of these laws 
 to air pumps, compressors, aud like ma- 
 chinery is clearly illustrated. 
 
 The subject of Heat completes the pre- 
 limiuiiry part of the course. In addition 
 to studying the nature and effects of heat, the student is made 
 sufficiently acquainted with the principles of chemistry to under- 
 stand combustion. 
 
 Throughout the preliminary, as well as the advanced subjects, 
 numerous tables and charts will be given, which will be of ines- 
 timable value to the student in his future practice. The text will 
 be copiously illustrated, as often a simple illustration will teach 
 more than a page of text. Every lesson in each subject will close 
 
 with numerous practical examples, in order to test the student's 
 understanding of that lesson before he proceeds. 
 
 The advanced course begins with the study of Streug'tli of 
 Materials. The object of studying this subject is to familiarize 
 the student with the properties of the various materials used in 
 machine constructions, with their behavior under stress, and with 
 the usual methods and formulas for calculating the proper dimen- 
 sions to safely resist any given stress. 
 
 Before undertaking the more complex problems, the student is 
 drilled in the principles of G-rapliical Statics. Graphical 
 methods of calculating are so exact, rapid and suggestive, that they 
 are largely replacing analytical methods in engineering practice. 
 Begininng with a few examples in graphical arithmetic, and hastily 
 reviewing the principlesof the triangle of forces, studied in physics, 
 the student is taught to apply this method to the determination of 
 stresses in engineering structures. 
 
 In the study of Mechanics of Materials both the analytical 
 and graphical methods are used, the former that the student may 
 obtain a more thorough understandiiuj of the conditions existing 
 in any piece under stress, and the latter that he may learn how to 
 quickly make the necessary computations. The stress in beams, 
 long columns and shafts are determined and illustrated by e.'jamples. 
 The moment of inertia, radius of gyration, and moment of resistance 
 are explained and their use illustrated. 
 
 Kiueinatics treats of the motions peculiar to machinery, consid- 
 ered as change of position solely. It teaches the nature and equiva- 
 lence of mechanisms and how to combine the kinematical elements 
 in designing new machinery. The subject is studied mostly by aid 
 of the drawing board. The student makes skeleton drawings of a 
 number of mechanisms and determines the velocity ratios of their 
 parts. Problems in link, valve, and differential motions, as well as 
 high-speed engine governors, are investigated.

 Dyuamics of Macliiuery deals with the forces acting in and 
 transmitted by machinery. Cranes, hoisting macliinery and other 
 simple examples are first studied, and the forces acting in each part 
 under a given load and condition are determined. As the student 
 progresses the subject of friction is taken into account and the forces 
 as modified by this factor are accurately determined. Starting 
 with an assumed steam diagram, all the forces acting in an engine 
 at each point of the stroke are determined. Other practical exam- 
 ples are also solved. Under this head the student completes his 
 study of the governor bj' determining the actuating forces. Illus- 
 trative examples are taken from well-known engines. 
 
 A thorough understanding of these subjects forms a basis for 
 the rational Designing- and Invention of Machines. The 
 student learns to design machinery by actually designing it from 
 data furnished as it would occur in practice. Simple fastenings, 
 bearings, shafts, levers, and connecting rods are designed, both 
 analytical and graphical methods being used. Special attention is 
 given to gearing, and practical methods are given for constructing 
 the correct tooth profiles. 
 
 The student then undertakes the design of special machinery. 
 The work covers a wide range, the intention being to fit the student 
 for any kind of machine designing. He begins with the design of 
 steam engines from an assumed diagram, carefully determining the 
 play of forces in all its parts, and calculating their proper dimen- 
 sions. Machine Tools, Hydraulics, Electrical and Mill machinery 
 are each studied and designed. 
 
 In considering machine plants, instruction is given in the selec- 
 tion and advantageous arrangement of machinery and accessories. 
 The building of foundations and erecting of machinery is also 
 treated thoroughly. 
 
 The student is taught the elements of electricity and the princi- 
 ples of dynamo- electrical machinery, which is coming into such 
 general use wherever machinery is employed. Particular attention 
 
 will be paid to the use of electricity as a mode of transmission of 
 power in a shop. 
 
 It should be borne in mind that our courses are not superficial. 
 It will require hard work to satisfactorily complete a course, but 
 the student will have learned something. 
 
 He can feel assured that his money and time have been well 
 
 spent.

 Course in Steam Engineering. 
 
 VERY year the demand from our industrial 
 organizations for men of higher education 
 increases. The test for promotion is becom- 
 ing more and more an educational one. "It 
 is the individual who reaches the highest 
 round of the ladder, not the many." He 
 who would gain the top must supplement 
 his practical knowledge with a technical 
 education. 
 
 Steam-plant owners are just beginning to realize the enormous 
 waste of fuel which annually occurs. They are learning that it is 
 far preferable to pay an educated engineer a good salary and have 
 a small coal bill, than to have a cheap engineer and a large coal 
 bill. The development of the steam engine has progieseed so 
 rapidly in the past twenty-five years that the best results are only 
 obtained by a thorough understanding and intelligent application 
 of the theoretical principles on which it operates. It is not suffi- 
 cient that the engineer should know enough to open and close the 
 throttle, to oil the bearing, to watch his gauge glass, and to shovel 
 in sufficient coal to keep up the steam. He must understand how 
 steam is formed ; what are the best conditions for the economical 
 apnlication of the heat of the furnace to the production of steam ; 
 how he can reduce priming and produce dry steam ; and, above all, 
 he must understand the chemistry of combustion and how he can 
 produce the necessary heat with the least coal. He must be able to 
 tell if his boiler has the proper grate area, and his chimney is the 
 right size, and to make a complete boiler trial to see if he is obtain- 
 ing sufficiently good results. He must understand the action of 
 
 the steam in the cylinders, the effect of lap and lead on this action 
 and how an indicator card tells the story of the setting or the 
 leakage of the valves, and of the amount of steam consumed. He 
 must understand ho w the forces are transmitted from the p'ston to the 
 shaft, and how to calculate the strength of all the parts, and as most 
 plants now contain a small lighting equipment, he must understand 
 the general principles of electricity. 
 
 The man who knows all ttiis will be a very valuable employee 
 and certain of promotion. He will take pride in reducing his coal 
 bill to the lowest notch. If any part of his plant is not giving 
 economical results he will know it and know how to improve it. 
 If any part of the boiler or engine is subject to excessive strains he 
 will know it and guard against accidents. If any repairs are needed 
 he can make a drawing of the required parts and order them made. 
 If any additional machinery is required, he can determine the 
 proper size of engine and boiler, and calculate all pulleys, gears, 
 shafting, etc. In most cities and someStates, engineers are required 
 to obtain a license by passing a technical examination. Other 
 States are being urged to pass similar laws, and it will not be long 
 until every State will require educated engineers. Every marine 
 engineer must now pass an examination before he can obtain a 
 license. 
 
 It is the purpose of the Institute to furnish all this knowledge 
 and much more to any one W'ho will study the course here outlined ■ 
 In order, however, that the student may be able to understand all 
 the techical subjects, it is necessary for him first to master the pre- 
 liminary subjects of Mathematics, Physics aud Mechanical 
 Drawing. The student need only know how to read and write

 in order to take this course. He is started at the verj' beginning 
 of arithmetic, and is given thorough instruction in all the rudiments 
 of the subject. Algebra, Geometry and Trigonometry are treated 
 in very much the same way. Great care is taken to aive only that 
 whicli is of most practical use, and yet to give an adequate and 
 compreliensive idea of the subject. In Trigonometry the student 
 is taught the use of the trigonometj-ic and logarithmic tables in the 
 solution of prolilems. 
 
 In Mechanical Drawing the stu- 
 dent is taught how to make shop 
 drawings. Working drawings are 
 ^^^ made from sketches of various ma- 
 
 fr^MBJ chine elements. 
 
 K ^^ ' The course in Physics begins 
 
 with elementary mechanics, and 
 takes up in succession hj'dro- 
 . .^ dynamics, pneumatics and heat. 
 
 The course throughout is illus- 
 trated atid explained by simple 
 experiments with which the stu- 
 dent is already familiar, or which 
 he can easily perform with the sim- 
 
 plest home-made apparatus. 
 
 The theory of hydraulic machinery and air compressors is fully 
 explained. 
 
 The subject of Heat completes the preliminary part of the course. 
 Radiation, conduction and convection are studied with special 
 reference to steam engineering problems. The student is made 
 sufficiently acquainted with the principles of chemistry to under- 
 stand combustion, and how to calculate the heat due to the com- 
 bustion of any fuel when its analysis is known. 
 
 Throughout the preliminary, as well as the advanced subjects, 
 
 numerous tables and charts will be given, which will be of inestim- 
 able value to the student in his future practice. The text will be 
 copiously illustrated, as often a simple illustration will teach more 
 than a page of text. Every lesson in each subject will close 
 with numerous practical examples iu order to test tire student's 
 understanding of that lepson before he proceeds. 
 
 The advanced special course begins with the study of Strengtli 
 of Materials. The object of studying tliis subject is to familiarize 
 the student with the properties of various materials used in Ma- 
 chine construction ; with their behavior under stress, and with 
 the usual methods and formulas for calculating the proper dimen- 
 sions to safely resist any given stress. 
 
 Before undertaking the more complex problems, the student is 
 drilled in the principles of G-vapliical S tatics. Grapliical meth - 
 ods of calculating are so exact, rapid, and suggestive tliat they are 
 largely replacing analytical methods in engineering practice. B^,- 
 ginning with a few examples in graphical arithmetic and hastily 
 reviewing the i^rinciples of the triangle of forces, studied in physics, 
 the student is taught to apply this method to the determination of

 obtain a more thorough understanding of the conditions existing 
 in any piece under stress, and the latter, that he may learn how to 
 quickly make the necessary computations. The stresses in beams, 
 long columns, and shafts are determined and illustrated by ex- 
 amples. 
 
 The student is now prepared to design the details of Steam En- 
 gines such as cylinder body, piston, piston rod, connecting rod, 
 cranls; pin, crank-shaft and fly-wheel. Under this head are also 
 considered the subjects of friction, lubrication, and wear of 
 parts. 
 
Department of Engineering. 
 
 33 
 
 The details of construction of Steam Boilers are studied, and 
 the sides, ends, soanis, and stays are calculated for strength and 
 safety. 
 
 Therniotlyiiamics or the Mechanical Theory of Heat, is the 
 science whichtreatsof the relations existing between heat and work. 
 It is necessary that the engineer should have a thorough knowl- 
 edge of this science in order that he may understand the proper- 
 ties of steam and its action in producing work. By means of it he 
 determines the efficiency of an engine compared witti the calorific 
 power of the fuel ; he may design the volume of cylinder to do a 
 given amount of work and determine the fuel required ; and he is 
 lead to appreciate the importance of saving heat, and to see where 
 and how it may be accomplished. 
 
 With this knowledge the student is able to design engines and 
 .boilers. He is taught how to calculate the proper size of cylinders 
 for simple, compound, and triple expansion engines. Valves and 
 valve-gears are studied by means of Zeuner's diagrams. The prin- 
 ciple of the governor is explained and illustrated by examples. 
 The losses in the cylinder are considered, and the effect of jacket- 
 ing discussed. The action and use of the condenser are explained. 
 The student is taught to calculate the proportions of a boiler setting 
 and chimney on scientific principles. The value of mechanical 
 stokers, feed-water heaters, and other accessories are discussed, and 
 the theory of the injector is fully explained. 
 
 Full instructions are given for making complete boiler and en- 
 gine tests according to standard methods, and for calculating the 
 results. The determination of the approximate steam consumption 
 of an engine from the indicator card direct is explained. The pe- 
 culiarities of locomotive, marine and other engines are described 
 and their operation exjilained. 
 
 In the construction of plants the engineer is given points in the 
 
 selection of an engine and boiler for the work to be performed ; 
 the arrangement of the machinery and accessories in the building ; 
 the building of foundations and the erecting of both engine and 
 boiler. 
 
 The student is taught the elements of electricity, and the prin- 
 ciples of dynamo-electric machinery sufficient fur an intelligent care 
 of same. 
 
 It should be borne in mind that this course in Steam Engineer- 
 ing is thorough and not a superficial one. It will require hard 
 work to satisfactorily complete the course, but the student will 
 have learned something. 
 
 Course in Practical Steam Engineering. 
 
 A .short course maybe taken by those who for various reasons 
 cannot take the full course. It is short in that it omits some of the 
 subjects ; but in the subjects taken, the text and instruction for the 
 two courses are identical. The short course of study comprises 
 Mathematics, Mechanical Drawing, Heat, Thermodynamics, Steam 
 Engine and Boiler designs, Steam Engine and Boiler trials, and 
 Construction of Plants. 
 
 This shorter course omits the subjects relating to Mechanics and 
 Machine design, and confines itself strictly to the theory of the 
 steam engine. It will be of great value to the practical mechanic 
 or engineer who wishes to acquire a thorough understanding of the 
 principles of combustion, the production of steam and its action 
 in the cylinder, the use of the indicator, the method of making 
 and computing boiler and engine trials, and the theory of com- 
 pounding engines.

 A Reflection. 
 
 What future is there for the man who labors only with his hands ? 
 He may gain much skill and be of great value, but there is the 
 end. The man who adds to the skill of his hands the equally 
 skillful use of his brain finds no limit to the possibilities of his 
 future.

 Courses in Architecture. 
 
 A RCHITECTURE is daily growing to be one of 
 
 J^^ the most important of the professions. Tliis 
 
 X^^ is exemplified by the increasing demand for 
 
 : f vL well-equipped draftsmen. To supply this 
 
 f ^^ demand our various technii'al schools are yearly 
 
 turning out increasing numbers of graduates 
 
 prepared to till responsible positions. It is not 
 
 possible for every one to have all the advantages 
 
 of college training but, " whi re there is a will, 
 
 there will be a way," and the Correspondence 
 
 School in Architecture comes to your assistance and will enable 
 
 you to accomplish by diligent and faithful work what many who 
 
 have the best of training fail to do. 
 
 It is possible to learn drawing and designing by our method of 
 correspondence instruction. 
 
 A thorough knowledge of drawing is the basis of all architecture 
 as well as of all other branches of IMechanical Science. 
 
 This being the case, drawing must be the principal subject and 
 groundwork of these courses. 
 
 The student begins by drawing lines and curves and learning the 
 simple problems in constructive drawing such as, how to bisect a 
 line or an angle, how to construct simple geometrical figures and 
 the theory and practice of drawing to various scales. As the stu- 
 dent progresses he becomes familiar with the best methods of 
 working and is gradually led from simpler constructive drawing to 
 the more complex methods of projection. 
 
 Architectural drawing is of course founded on mechanical draw- 
 ing, but it is in itself a special branch. To the architectural drafts- 
 
 man, architectural forms must be familiar, so the student is very 
 soon put to work drawing out plans, elevations and sections of cor- 
 nices and other architectural details in order that he may become 
 familiar with them. 
 
 The five orders of architecture must be carefully drawn out. 
 Throughout an architectural career these five orders, or the various 
 modifications of them, will be found to be indispensable, so their 
 careful study is absolutely necessary. 
 
 Details of classical architecture will accompany the orders and 
 a thorough knowledge of classical architecture will thereby be 
 gained. 
 
 The successful architect of to-day is the one who can design in 
 the classical styles, whether it be a hotel, theatre, store, office 
 building or private residence. 
 
 The popular style of to-day, yesterday, and to-morrow is and 
 will always be some modification of them as they seem to meet 
 the various conditions of living more completely than any 
 others. 
 
 It is important that one should be familiar with all styles, but 
 they are so varied it is impossible to obtain more than a speak- 
 ing acquaintance with them in a course of this character. 
 Having mastered the classical styles, the student will find that the 
 others will come naturally by observation and study. 
 
 Next, the designing of simple structures will be taken up and 
 the student taught the essentials of good planning. At first small 
 buildings will be designed, but they will lead to larger and more 
 complicated ones. 
 
 As the student's horizon becomes more extended he will be 
 
36 
 
 National Correspondence Institute, Washington, D. C. 
 
 shown how to construct his buildings and malce the details for 
 them. 
 
 It is deemed of great importance that a thorough knowledge of con- 
 struction be imparted, as a well-designed building poorly constructed 
 will be of very little credit to the designer and less to the owner. 
 As the course in architectural drawing progresses, other branches 
 p of drawing essential to the good drafts- 
 
 • ^ ■" , man will spring up and must be mas- 
 
 ^ tered. A proper knowledge of shades 
 and shadows naturally succeeds sim- 
 ple projection, and perspective will 
 follow as a matter of course. 
 
 Every architect should be able to 
 make a perspective drawing of his 
 1 design in order that he may see just 
 how it will look in reality, and that 
 others may see it, too. One thing 
 leads to another, and the student will 
 iind almost before he is aware of it 
 that he has a knowledge of Stereotomy 
 and will be able to draw out in 
 isometric projection details of arch- 
 stones, window-sills and other pecu- 
 " liarly-cut pieces of stone, and, if 
 
 necessary, be able to cut them out of paper and paste together so 
 as to form an exact reproduction to a smaller scale of the particular 
 piece he may be working on. 
 
 By this time the student will be very well advanced and can de- 
 vote himself almost entirely to designing and free-hand drawing 
 and sketching. A knowledge of these subjects makes designing 
 easy, as a facile pencil facilitates ideas and will prove of immense 
 value to a draftsman in more ways than one. 
 
 The Course in Architecture. 
 
 This course is complete in that it comprises all the subjects, both 
 practical and artistic, necessary to make a thoroughly equipped 
 architect. 
 
 A preliminary training, such as one would get in the average 
 high school, is essential, and is provided for in the course. 
 
 A knowledge of the elementary studies, such as Arithmetic, 
 Geometry, Trigonometry, and the simpler forms of Algebraical 
 formulas. Physics, History, etc. , is given as a ground-work upon 
 which to build a thorough knowledge of the profession. Begin- 
 ning with mechanical drawing and the theory of projection, shades 
 and shadows, the student is introduced to architecture proper by a 
 sludy of the five orders of Classical Architecture. 
 
 Each order will be carefully drawn and the various proportions 
 studied. 
 
 Order of Subjects. 
 
 Architectural History will be begun and will be continued 
 through the course. Free-hand drawing will go hand in hand 
 with the more precise mechanical drawing. Stereotomy, or the 
 developing and drawing of the various odd-shaped stones which 
 form the arch and vault, will follow shades and shadows, and will 
 be followed by graphical statics, or the graphical method of dis- 
 covering the stresses and strains in beams, trusses, girders and the 
 like. The principles and the simpler forms of architectural de- 
 sign will then be taken up. 
 
 The course in Geometrical Drawing will be concluded by per- 
 spective, a knowledge of which will enable the draftsman to make 
 a picture of the building or object he may have designed. 
 
 Materials and the principles of the different kinds of construc- 
 tion as practised to-day will precede the subject of specifications

 strength of materials, ijlunibing and drainage, licating and ventil- 
 ation, and estimating, in the order named. 
 
 The subject of Architectural Design will include the planning of 
 the simplest structure as well as the most complicated, and will 
 fully explain the problems to be met with in practice and their 
 legitimate solution along artistic lines. To finish the course of 
 Architectural Design, the student will be i-equired to select a sub- 
 ject for a final design, or thesis, which will be of a monumental 
 character, such as a museum of tine arts, a public library, or other 
 building of similar nature, and he will be shown how to study and 
 finish the drawings in a manner to satisfy the requirements of any 
 public competition. 
 
 Competitions provide a sure means of acquiring a reputation of 
 the best sort, and when a young man wins one his professional 
 career is most favorably begun. 
 
 The Course iu Architecture is intended as a review for 
 those who are more or less familiar with the subject and for those 
 who may have the necessary preliminary training. 
 
 Students, mechanics, builders, clerks, etc., can, by taking this 
 course, obtain sufficient knowledge of architecture, both practical 
 and artistic, to enable them to fill responsible positions. It will 
 give them such a foundation that they can easily solve the more 
 dilficult problems which will constantly occur. This course will 
 prove of great advantage to those who are interested iu archi- 
 ture but who may be unable to pursue the study of it in the ordinary 
 way. 
 
 Course in Architectural Drawing and Designing. 
 
 This course is, as its name implies, a partial course. Some of 
 the less important subjects are omitted, giving only the essential 
 ground-work. The bright student will be able to continue bis 
 
 studies unassisted after having taken this coui.-e 
 value to draftsmen generally.

 The Course in Architectural Drawing. 
 
 Mechanics and artisans too often are unable to thoroughly under- 
 stand and read drawings. When they wish to express their ideas 
 on paper they are generally unable to do so, owing to their lack of 
 knowledge. By taking this course they will be able to compre 
 hend drawings at a glance, saving time and trouble and possible 
 loss to their employers. A man who has this knowledge of draw- 
 ing is of especial value to his employer and can command higher 
 wages in jiroportion to his greater worth.

 WIio is Master ?— Man or Machine ? 
 
 Every day new machines take up the work which was before 
 done by hand. The mm displaced, too often merely laments his 
 fate, accepts the situation and settles down, content merely to feed 
 the machine. But if he undertakes to study it, he sets the machine 
 in his head to going. If he keeps that machine — his brain — at 
 work he will find that his brain will help him conquer the man- 
 made machine, make him independent of it, and open the way for 
 him to do more than merely nurse some machine. With the most 
 wonderful power at his command, man too often neglects the ad- 
 vantage it gives. But he must learn how to use it. 
 
 The food of the brain is study ; a little of such nourishment 
 creates a craving for more, and pr0t)erly directed study produces 
 wonderful results. The man is then able to use his brain, and the 
 machine is no longer his master.

 Courses in Mechanical and Topographic Drawing.

 fNSTRUCTION in Mechanic-al or Topographic 
 ' Drawing forms a verj' important part of eacli 
 
 j 71 of the different courses of the Department 
 
 of Engineering. The work done in connection 
 with these courses affords the student valuable 
 training in the general principles and the 
 fundamental practice of mechanical drawing, 
 with special instruction in the particular 
 branch of drawing suitable to the needs of 
 the particular course. The instruction is 
 the same for all courses, up to the point wliere a substantial 
 foundation has been laid for further progress in the drawing of 
 machinery for the Mechanical EngineeringCour.--e, structures of all 
 kinds for the course in Structural Engineering, Architfctural 
 Designs, Topography, etc., depending on the line of work the 
 stu<lent is pursuing. 
 
 For the benefit of these who prefer to omit, or to postpone to 
 some more convenient period, a study of the technics and theory 
 of Engineering; and also for those who propose to devote their 
 entire attention to drawing, we have prepared two courses in draw- 
 ing, separate from the Engineering Courses. These are : first, the 
 Complete Mechanical and Topographic Drawing Course for those 
 who desire to become thoroughly capable in all the varieties of 
 technical drawing ; second, the Course in Mechanical Drawing for 
 those who wish a thorough training in technical drawing, but de- 
 sire instruction in those particular branches only that are more com- 
 monly employed. 
 
 [n the following description of the line of instruction pursued 
 in the course of Complete Mechanical and Topographic Drawing, 
 the preliminary work is that given in all courses of which drawing 
 forms a part. Tnen in our other courses we give the student work 
 in the kind of drawing particularly applicable to that course, while 
 our complete drawing course includes some work from all the tech- 
 nical courses. 
 
 As a preliminary we will state that any one may become a 
 good draftsmau ; to some it may come more easily than to 
 others ; but with patience and care any one may acquire that most 
 valuable art. 
 
 Course in Complete Meclianit-al and Topog'faphic 
 Drawing'. 
 
 The subjects of mathemetics and the elementary mechanics are 
 first taken up, as they are the foundation of all technical drawing. 
 
 This is followed by a discussion of drawing instruments and 
 materials, their selection and use, together with hints of great 
 value to the student in actual practice. 
 
 We take great pains to start him right, so that he may not acquire 
 faulty habits, which in time become very difficult to correct, and 
 which may interfere with his development as a draftsman or injure 
 his eyes. Illustrations are freely used to make clear the proper 
 handling of the draftsman's tools and material. The work in actual 
 drawing begins with the lines and curves, followed by easy con- 
 structions with the necessary geometrical and mechanical problems. 
 
40 
 
 National Correspondence Institute, Washington, D. C. 
 
 
 After this the student will take up the construciion of sections and 
 projections. Then will come line shading of curved surfaces and 
 section lining, followed by instruction and practice in the use of 
 water-colors, with instruction and practice in such free-hand draw- 
 ing as is found necessary in Mechanical and Topographic Drawing. 
 Instruction in tracing and blue prints will conclude what may be 
 considered the prelindnary drawing work of all the courses. 
 
 After this will be taken up 
 more complex work of machine 
 drawing, truss and bridge work, 
 or structural drawing in general, 
 architectural drawing, map mak- 
 ing, and topographic drawing. 
 
 Upon the completion of this 
 course the student will be fully 
 equipped as a professional drafts- 
 man, ready to take up work of 
 any character. 
 
 In going through this course 
 the student will work from care- 
 fully finished plates, or from rough 
 sketches with measurements, as 
 the needs of the different parts 
 of the course may require. 
 Throughout all the work close 
 attention is paid to the subject 
 of lettering, and the student is 
 carefully trained in this most 
 important detail. 
 
 The course will include thorough training in the preparation of 
 drawings for the United States Patent Office. The rules of 
 the Office are very strict ; and 50,000 applications for patent are 
 
 tiled annually, accompanied by an average of two sheets of drawing 
 each ; a considerable number of these drawings are rejected each 
 year, and must be re-drawn. These drawings come from all parts 
 of the United States, and a large field of work is open in each of 
 our principal cities to those who are expert in the preparation of 
 drawings for the Patent Office. Our instructor has had extensive 
 experience in this line, and the instruction in it will be thorough. 
 The Course in Meclianical DraAving' differs from that above 
 described only in extent, the training is just as careful and thorough 
 and the instruction is just as complete ; but there are not so many 
 special classes of work taken up. An examination of the following 
 synopses of the courses will show fully the difference between 
 them :

 A Mystery Unveiled. 
 
 To the man who does not understand Mechanical Drawing, it 
 seems a mysterious art, beyond the power of the average man to 
 understand. Yet what is it all ? Nothing but straight lines and 
 curves and nearly all made by machine, ihe handling of most 
 machinery looks complicated to those ignorant of the principles 
 of its working; but yet the average man with practice and teach- 
 ing can master it. So with drawing-ordinary shop drawing can 
 be learnt by any one who makes a fair trial at it. And while it is not 
 possible for everyone to become a draftsman of the highest grade, 
 excellence in this line is within reach of a far greater number of 
 people than most persons would suppose. You may be sure that 
 if you try you can become a draftsman, possibly even a 
 very good draftsman. In our experience we have seen remarkably 
 fine work devel )ped from very poor beginnings.

 ITH these courses the more complicated and diffi- 
 cult questions of the subjects of Mathematics 
 and Mechanics are taken up. These courses 
 may be taken separately by those who are 
 acquainted with subjects properly preliminary to 
 them. One or both of these courses form a 
 necessary part of the instruction of candidates 
 for degrees. The holder of a degree from the 
 National Correspondence Institute will 
 be equipped with all the theoretical knowledge 
 that is required for (he same degree in any 
 college in the country. See pages 10, 13 and 43. 
 
 The instruction of the regular courses prepares the student to 
 understand these more abstruse matters ; he will find himself 
 fully able to conquer them ; and so crown his efforts toward the 
 acquisition of a profession by qualifying himself for the solution 
 of the problems which call for the services of engineers of the 
 highest standing. 
 
 In submitting this description of the courses of our Engineering 
 Department for your considei'ation, we wish to state that it has 
 been carefully prepared, having constantly in view the omission of 
 everything that might confuse tlie 
 average reader in examining the in- 
 struction we offer with the intention 
 of understanding how it will benefit 
 him. But we realize that there may 
 be points, differing in each case, upon 
 which further information may be de- 
 sired. 
 
 Therefore, we ask you to advise 
 us if theie is anything in this book 
 that needs further discussion on ac- 
 count of the special circumstances 
 of your own situation. We will be 
 very glad to answer any questions you 
 wish to ask, or to give you advice 
 about the course most suitable to you, 
 or to assist you to overcome any diffi- 
 culties and doubts that may be in the way of your eflbrts to im- 
 prove yourself.

 Enpflish Course for Eno-meerino^ Students. 
 
 OURSES in English have been arranged for our 
 different Departments in accordance with the 
 regular practice of the Na-tional Correspondence 
 Institute (that of giving exactly what the stu- 
 dents need and only that) ; and our Engineer- 
 ing students will find this course well adapted 
 to their needs if they require training in the 
 English Branches. 
 
 The engineer is frequently called upon to submit I'eports con- 
 cerning enterprises which may be under consideration. Not only 
 mu.st these reports be clear, exact and definite in their explana- 
 tion of technical matters, but also the language used must be such 
 that the meaning intended will be easily apparent. A poor pre- 
 sentation will surely affect the employer's opinion of such a report, 
 no matter how great its professional merit. Consequently, it will 
 sometimes happen that an opportunity for employment in an im- 
 portant work will "I)e lost because of the unfavorable impression 
 made by the engineer's report. 
 
 In all other matters which it may be necessary to put in writing, 
 an ability to use good English is just as essential. The engineer is 
 expected to be a man of education, and most persons, unable to 
 judge of the technical part of his education, will judge him by his 
 knowledge of the common English branches. 
 
 No student (who stands in much need of instruction in English) 
 can complete a course in our Department of Engineering without 
 more or less improvement of his English, but, of course, only a 
 passing attention can be paid to language in a scientifio study, and 
 those who^are deficient in the English branches should take ad- 
 
 vantage of the opportunity offered by the Institute to perfect 
 themselves in this respect. The work of English may be carried 
 on without interference with the engineering studies ; and the 
 student will find it a pleasant change to turn from one to the other 
 
 The English course for engineering students consists of orthogra- 
 phy, punctuation, capitalization, grammar (especially construction 
 of sentences) and elements of rhetoric. In orthography, the 
 students will be drilled in the spelling of some twenty-five hundred 
 or more words of common usage, in which will be included most 
 of the technical words which the engineer will need in his profes- 
 sion. The drill in punctuation will be in the correct use of the 
 various punctuation marks : period, comma, semicolon, colon> 
 dash, etc. In capitalization, the correct use of capitals will be ex- 
 plained and practice in their use will be given. The instruction in 
 grammar will not go deeply into theoretical grammar, but will aim 
 to familiarize the students with the use of correct English so that 
 they will think grammatically and, therefore, will express them- 
 selves in irreproachable language unconsciously and without 
 labored effort to that end. It will be the aim in rhetoric to 
 instruct our students in those mattei-s which pertain to the appear- 
 ance of the written page and to the form in which to cast one's 
 ideas: the paragraphing, the best method of presenting thought, 
 the essentials of a description, etc. 
 
 Arithmetic is not a part of the English Course for Engineering 
 Students, because that subject is very thoroughly gone over in the 
 Engineering courses. 
 
 "The terms for this course are $8 cash in advance; or §10 in 
 monthly installments of v^o each; or §12 in installments of S2 each. 
 
 There will be no text-books to buy, as we supply all reading 
 matter needed in the course.

 Are you included in one of these three 
 classes ? 
 
 1. Those who, on account of youth or of 
 being needed at home, are unable to leave 
 home or business to attend collei;e. 
 
 Those who have been compelled, for 
 L any reason whatsoever, to give up a college 
 (course after they have begun it. 
 
 . Those older ones who wish to supply 
 Tthe omissions of their earlier education. 
 
 If you are one of those, this page is in- 
 tended for you. We ^re not offering to give 
 students all of the advantages of a coui'se in 
 college ; we rather advise all who can do so, to enter some good 
 university and to complete their courses there. But to those who, 
 for some reason, are not able to attend a university during the four 
 years necessary for a degree, we offer a snlistitute which has much 
 to commend it. This is a tliorou.i;h (■<lii<-atioii by corre- 
 spoiideiice, with a degree at its close to attest it. 
 
 The chief a.lvantages of a course by correspondence may be 
 summed up as follows : 
 
 Money is Saved. — Expenses of travel and of board away 
 from home are cut off, and the expense of tuition is reduced. 
 
 Time is Saved.— The student does not have to attend lectures 
 at certain specified hours, with the consequent loss of time owing 
 to preparations to leave his boarding house, the tramp to the college, 
 the tramp back (or expense of carfare), the resuming of his house 
 coat and slippers for work again and the taking up again of the 
 train of thought which was interrupted a couple of hours before. 
 
 Biisiue.ss is Saved.— The studeot may study at home, mak- 
 ing his study hours suit his convenience, which enables him to 
 maintain his bu-in<=ss while he pursues his studies. 
 
 Tlie Student Gains a more personal, individual attention 
 than is possible to instruction in classes. 
 
 The Student Progresses more rai>id'y, because he is not 
 held bat k l:)y the one or two dull or lazy or negligent pupils, who 
 are nearly always present in every class. 
 
 Special Courses are given in Astronomy, Botany, Chemistry, 
 Geodesy, (ii'iiliitiv, Meteorology, Mineralogy, Physics and Zoology. 
 
 Graduation Courses leading to the degree of Bach^^lor of 
 ScieiK-e (B. S.) consist of elective studies from the above with 
 certain required studies in English, Modern Languages (French and 
 German), History, Mathematics, Drawing and Philospliy. Those 
 who enter for a degree must pass satisfactory examinations at the 
 completion of every subject, and must, at the close of tlie course, 
 pass a satisfactory examination on all of the subjects of the course. 
 
 Our method is different from those built upon the University 
 Extension, Cosmopolitan or Chautauqua plans. Our assistance is 
 not limited to outlii e, suggestion, and "keeping tab" on the 
 student, but it includes, also, active, personal instruction wherever 
 the studeat needs it. It differs from the regular college work in 
 that ours is written, while the class recitation is oral. 
 
 Our Faculty is a collection of bright, brainy, college men, who 
 know what students need and how to supply those needs. \Ve in- 
 vite cori-espondence froui all who have a desire for academic 
 honors or who wish to pnisue .some special line of study.

 OURNALISM

 Positions. 
 
 Among all modern professions Journalism 
 is the most powerful, the most fascinating, the 
 most remunerative. The steadily-increasing 
 demand for well equipped writers has led the 
 National Correspondence Institute to 
 provide a new and attractive plan for preparing 
 students in journalistic woik, the most beneficial 
 returns being assured for the least expenditure 
 of time and money. 
 
 All the great authors of to-day first entered 
 the journalistic field. The path which they 
 have trod to fame and financial success is 
 open to thousands of men and women who need 
 only to have their latent talents developed and 
 directed. The Schools of Journalism in the large cities, which 
 compel the actual attendance of the pupil, do not meet the require- 
 ments of the situation. They are unsatisfactory and expensive. 
 In teacliing Journalism by Mail we have solved the problem 
 of imparting complete knowledge of the journalistic art to each 
 individual student. Your Spare Moments are the rounds 
 of the ladder upon which you can mount to success. The plan is 
 endorsed by practical journalists. 
 
 Mr. West, who has personal charge of the Department of 
 Journalism of the National Correspondence Institute, is one of the 
 most accomplished, successful and versatile journalists at the Na- 
 tional Capital. Mr. West has had long experience in training 
 journalisfs, and many of the most noted members of the profession 
 have graduated from under his instruction. He is commended by 
 the most distinguished of the brilliant corps of Washington corre- 
 spondents and has himself achieved a high reputation as a maga- 
 zine writer. He is admirably capable of imparting the results of 
 his long experience and knowledge to the students of the National 
 Correspondence Institute. He will be assisted in his work by a 
 corps of specially -selected assistants. 
 
 The courses are divided as follows : 
 
 Practical Course.— Acquaints the student with every detail 
 of Journalistic Work ; this includes Rhetoric and Style; How to 
 begin work as a Reporter or Correspondent ; Methods of Journalis- 
 tic Work ; The Art of Interviewing ; Editorial Writing, etc. 
 
 Complete Course.— Embraces all of the Practical Course and 
 in addition Book Reviewing ; Dramatic Criticism ; Essay Writing ; 
 Short Story Writing; City and Managing Editors' Work, etc. 
 
 Select Course.— Embraces subjects selected from the Practical 
 and Complete Courses and designed for Teachers, Lawyers, Doctors — 
 in fact, all professional and business men and women who desire 
 instruction in composition and literary work as an accomplishment 
 and who do not wish to follow journalism as a profession. 
 
 Special Course. — For those who have endeavored to secure 
 acceptance of literary work, but have failed to gain a foothold in 
 the ranks of successful authors. Publishers have neither the time 
 nor inclination to criticise the manuscripts which they find 
 unavailable. Our Department of Rejected Manuscripts in this 
 course, supplies this need, making story writing a lucrative employ- 
 ment. 
 
 The system which we have adopted is thorough, practical and 
 successful. It teaches Journalism by methods which are easy 
 to understand and certain in their results. There is no time-limit 
 to the courses, but each pupil is given ample opportunity to become 
 proficient without interfering with the regular work in which he 
 orslie may be otherwise engaged. 
 
 The Diploma which will be finally awarded will be of value 
 in securing employment. Students with adaptability and talent 
 can easily make their expenses by journalistic work while engaged 
 in acquiring a complete knowledge of all the details of the profession. 
 
 Our Plans provide practical assistance in securing employment.

 Degrees. — Graduates of this Department receive the degrees 
 of B. Acct and M. Acct. This Institute is incorporated by law, 
 with power to confer degrees the same as the leading Colleges and 
 Universities of the country, and in this has a decided advantage 
 over the ordinary Business College. 
 
 Not a " Feeder." — The instruction in this Department is com- 
 plete in itself and exdusivdy by correspondence. A student in Cali- 
 furnia is instructed in the same manner as one in Baltimore or 
 this city. This Department is not a side issue and a " feeder " for 
 a business college run in connection, with the object of securing 
 students ostensibly for correspondence instruction, and then draw- 
 ing them to the College to '' finish the course" at extra expen.se, 
 nor is it run for the purpose of selling text-books.
