It outlines the topics covered and makes statements which are supported by the data given in the body of the Memorandum. Reason for Memorandum . — The following statement is taken in full from the Introduction: This Memorandum was sugges the American Council of Education to University has gone forv/ard or backw Engineering Department was rated as made by that organization in 153^ an resigned from the staff ^-^ince that t sent for consideration the steps \-irA effect of that resignation and to gi in the appraisal of the v/ork of the to 19^2 as compared with that of pre ted by the survey being made by determine vjhether or not the ard since 193^» Since the Civil "Distinguished" in the survey d since one outstanding man has ime, it seems desirable to pre- ch x-'ere taken to offset the ve information which will assist department from the period 193^ oev'^ing years. Changes in Staff . — The resignations which have occurred since 193^ and the manner in which the vacancies were filled are as follows: Professor Hardy Cross resigned in 1937* The position was filled by Professor T. C. Shedd who had been selected for the staff by Professor Cross, x^rho worked with him here for I5 years, who is an outstanding teacher, and the author of txr'O leading treatises in his field. In addition, Dr. N. M. Newraark, a young man, was added to the staff in 193^ in a position especially created for him. Professor Cross in recommending him stated that "He is, I think, the ablest man we ever had in graduate work." Professor Westergaard stated, "I believe that his appointment will be a contribution to the diffi- cult problem of future distinction of the University. His intellec- tual capacity is rare. He ia among the fevj who can be rated as truly brilliant." Recently S. F. Kelley, Chief of the Division of Tests of the Public Roads Administration wrote "In ray opinion he is one of the outstanding men in the United States in the field of re- search in which he is engaged." Professor Stubbs resigned in 193^» The position was filled by the appointment of Mr, H. P. Evans. The following appraisal is selected from many comparable ones in the letters recommending him, Mr. Rockwell, his immediate superior at the U, S. Reclamation Bureau stated, "It has been mypriviledge, for more than 30 years, to with and supervise young engineers. I have man who, in my opinion, showed more promise has to an unusual degree the ability to grasp the vital points of a problem and arrive at a correct answer by clear straight thinking.... His intellectual capacity is of the highest order," His work on the staff has Justified this appraisal. never encountered than Mr. Evans He x-^rork a young ^-^xj^i^c-Mr- ~li- Mr. K. C. Tippy resigned in 1936, The vacancy was filled by Mr. J, G, Clark, one of our own graduates who had made' an excel- lent record and gave great promise for future development. He has lived up to our expectations. The work of the department has been strengthened since 1934 by two further additions to the staff, Mr. A, E, Cummings, recognized as being one of the foremost foundation engineers in the country, was appointed Lecturer in* Foundation Engineering to give regular lectures in credit courses. He has been extremely well re- ceived by the students, Dr, R, B, Peck, a young man who has already become nationally known because of his brilliant research in soil mechanics, was appointed Lecturer in Soil Mechanics in 19^2 to give regularly scheduled lectures and is 'to become a resident Research Assistant Professor next month, Dr, Karl Terzaghi, consultant on the Chicago Subway, selected him t9 take charge of the soil investiga- tions on that project. This proved" to be the largest investigation ever carried out in this field. Mr. _V. 0, McClurg,_in charge of structural design for Holabird and Root, leading architects pf Chicago, has said that he expects Dr. Peck to be Dr, Terzaghi' s successor as the foremost foundation engineer in the country. Considering these additions and adjustments which have taken place in the staff since 1934 it seems certain that, from this point of view, the staff has made substantial progress since 193^ in spite of the resignations which have trJien place. Changes in Curriculum , — A new senior option In Railways was added to the curriculum in 194o when the Department of Railway Engineering was dissolved. This year a new senior option. in civil engineering phases of aeronautics, and a new 5~year curriculum In Public Health Engineering were offered for the first time. These addition", were made to meet the increasing demand for men trained in these fields. The State Department of Public Health very strongly urged the establishing of the curriculum in Public Health Engineering, Development of Staff , — The members of the staff who were here before 1934 have shown marked development through the years. This is ^apparent to anyone v/ho is familiar with the work of the staff. For others, statistical information is given in this memo- randum which will assist in appraising this factor. This Includes research, technical book writing, articles in technical literature, service on committees of engineering societies, and assistance to public agencies. This information will be summarized in the follow- ing paragraphs. Research , — The number of Bulletins and Circulars by mem- bers of the civil engineering staff published by the Engineering Experiment Station for the last three nine-year periods is as follows: All Members Present Members ~" g ■',<■ .V. 1916-1924 1925-1933 1934-1942 ""T 15 28 13 27 -111- A comparison of individual publications will show that the research projects have become more comprehensive, and more significant, as the years have passed. The funds provided by outside agencies and by regular University salary appropriations for research in this department in the Engineering Experiment Station for the last two nine-year periods are: ^ j. ^ ^ r, -, ^ Outside Regular Sewage Agencies Salaries Research Total 1925 to 1933 I 83,000 $ 67,000 1934 to 1942 ^149,000 |!104,000 #27,000 I 150,000 #:'280,000 As noted above, there have been special appropriations of |3,000 per ear for sewage research beginning in 1934, making a total of 27,000 for the nine-year period. Other general appropriations^ are made for research. The above tabulations v^how that the funds avail- able for research have doubled during the last nine-year period. On the basis of the number of publications and the . ": funds devoted to resea,rch this^ activity by members of the staff has practically doubled during the* last nine-year period as compared with the preceding nine-year period. The quality of the work is indicated by the general approval and the increasing outside support which it receives. Professor W, it, Wilson devotes his full time to research. The quality of his research is very . definitely indicated by his being awarded three medals by engineering societies since 1934 for three papers he has given onhis research. Book Writing . — This department has been outstanding for the number, high quality and broad scope of the technical books it has produced. Data presented in the body of this Memorandum shows that the productivity of this department in this respect is continuing. Technical Articles . — The comparisons of the technical articles written by members of the staff during the last two 'nine- year periods show a marked increase during the latter period. The actual totals are: ^^^ Presnnt Members Members 1925 to 1933 77 65 1934 to 1942 128 122 The actual numbers are not important but the trend is significant. Technical Societies , — Every member of the staff is a mem- ber of the American S society in his field, other societies repre they are interested, 20, the total number member is 4,5, These Pi, to which most of ociety of Civil Engineers, the major technical In addition, members of the staff belong to senting the specialized activities in which The total num.ber of societies represented is of memberships is 76, and the average per staff figures do not include Sigma Xi and Tau Beta the staff members belong. -Iv- Statlstics gi staff are active on the the number of committee the past nine-year peri period.

This includes the Bureau of Ships and the Bureau of Yards and Docks of the U. 5. Navy, the U. S. Army Engineers, the Public Roads Administration, the National Resources Planning Board, the National Research Council, the Association of American Railways, the Highway Research Board, the Civil Works Administration, the Illinois Division of Highways, the Illinois State Legislature, the G-overnor of Illinois, the Illinois Planning Commission, the Illinois Emergency Relief Commission, the San Francisco-Oakland Bay Bridge Authority, the Tacoma Bridge Com^nission, and others. The fact that public agencies have come to this department for assistance on a great variety of problems, many of which are important, is a clear indication of the competence of the staff and the high regard in which it is held. The service rendered has always been helpful, frequently it has been very important, and in some cases can only be classed as extraordinary. Conclusion. — The information presented in this Memorandum shows quite clearly that any disadvantage which may have developed. from resignations since 193^ has been overcome, and that a distinct advance has been made by the appointnent of competent men to positions which did not exist previous to 193^. The curriculijn has oeen broadened to keep pace with develop- ments in the general field of civil engineering. The increase in activity and productivity of the depart- ment, as evidenced by research, writing and professional activities, has been very marked. No mention has been made of the teaching Salary budget. This has increased in keeping with the development of the staff member-. -v- All statistical comparisons which are possible indicate that the activity of the department has doubled during' the last nine-year period as compared with the precedinr^ period. As has been stated, the actual numbers and ratios are not Important but the trend is significant. The conclusion that the Civil Engineering Department has gone forward since 193^ seems to be definitely established by the material presented in this I.Iemoranduml The staff is progressive, competent', productive, and developing. Its morale and spirit are very high. The physical facilities for instruction and research are outstanding and are constantly being Improved. The Dublications and activities of Mr. Cummings and Dr. Peck, who are part-time members of the staff as Lecturers, have not been included in the statistical studies given_ in this Memo- randum although their inclusion might be justified. These would add materially to the record of development since 193'^» Memorandum on Developments in the Civil Engineering Department of The University of Illinois From 193^ to 19^^-2 INTRODUCTION This memorandum was suggested by the survey being made by the American Council of Education to determine whether or not the University has gone forward or backward since 193^» Since the Civil Engineering Department was rated as "Distinguished" in the survey made by that organization in 193^ and since one outstanding man has resigned from the staff since that time, it seems desirable to present for consideration the steps x\rhich were taken to offset the effect of that resignation and to give information which will assist in the appraisal of the work of the department from the period 193^ to 19^2 as conpa.red with that of preceding years. When a x^/ell-knovjn man leaves a department, there is a tendency to assume that that department has gone backward. This is commonly, but not necessarily, the case. If a competent man is added to the staff or, better still, if the staff has among its members younger men who soon can develop to fill the vacancy, the initial setback may be overcome. Hovrever, it must be recognized that a younger man will not usually be as well known as the person who has resigned. For that reason, the loss may be more apparent than real. Resignations and retirements must be considered as normal consequences of the passing of time. The vital question is how well they are provided for. In this memorandum, the trend of the department will be considered under several heads as follows: 1. 2. 5. Department Policies Concerning Staff Changes in Staff from 193^ to 19i^-2 Special Developments and Activities from 193^1 to 19if2 Comparison of Productivity and Professional Activities of Staff Members for the Nine-Year Period 193^ to 19i^-2 and the preceding Nine-Year Period 1925 to 1933. a. Engineering Experiment Station Publications b. Technical Book Writing c. Technical Papers, Articles, and Reports d. Committees of Technical Societies Summary (Placed at the beginning of the Memorandum for convenience) It is recognized that there are many other factors which enter into the determia-ition of the quality of the work of a department but no others are subject to statistical comparisons. 1 f- '-f -2- Of course, the most Importan of teaching for that is the department. However, it is definite way. So far as the cerned, it is certain that t since 193^ because, exceptin members have become more exp continually improving their t factor of all is the effectiveness principal work of any University impossible to measure this in any situation under discussion is con- eaching in the department has improved g the three resignations, the staff erienced in teaching and have been preparation for teaching. In examining the data which are submitted, it must be kept in mind that they include only a part of the factors which enter into the determination of a staff member's effectiveness. No statistical comparison of effectiveness in teaching is possible. A good teacher may be ineffective in research and one who is dis- tinguished in research may be a mediocre teacher, A staff member nay be of great value to the department even though he has not engaged in research and has not written for publication. Also, there are many departmental, college and university responsibilities whose performance is necessary to the proper functioning of the educational and research program. Some men are particularly effective in this phase of the staffs activity while others are not. As has been stated, these elements are not subject to statistical analysis but it must be realized that they are present. In order to be most effective a staff must be i/ell balanced in these various respects. Since most of the members of the staff have been here through the two nine-year periods, it can be assumed that they have shown t?ie same relative effectiveness in the various phases of the department's work during these two periods. This uncertainty would be present in comparing the effectivene of different staffs but does not enter the present comparison : any important way. iSS in 1. DEPARTMENT POLICIES CONCERNING STAFF Department Policy . — It has been the policy of the depart- ment for many years to so coordinate the members of the staff that any vacancy created by the resignation or retirement of a key member can be filled by another staff member who has been working with him and is adequately trained to step into his position. Such a policy is particularly important to this department at the present time because of the relatively large number of mature men noxir on the staff. The civil engineering staff is large enough to enable this policy to be carried out by^careful planning in the selection of new staff members and the duties which .are assigned to them. The ^ present department is well balanced. I Every effort is made to create conditions in the depart- 1 raent which will encourage the development of staff members. Young men are closely associated with more mature members of the staff I but are not dominated by them. Responsibility is placed on young men as rapidly as they are in position to carry it. They are given ~3- conslderable freedom in the procedures followed. Every effort is made to provide them with the facilities required for effective work. Their effectiveness is Judged by the results secured. Frequent comments by staff members and their desire to stay here in spite of opportunities to go elsewhere show their satisfaction with the conditions v;hich prevail in this department. 2. CHANGES IN STAFF There have been only three resignations during the nine- year period under consideration. This is a remarkably small turnr- over in a department of 17 men. However, one of these resignations was that of Professor Hardy Cross who had won distinction in structural engineering during his I6 years as a member of the staff. Another resignation was that of Professor F. W. Stubbs who had done very creditable l^rork. The third resignation was that for Mr, K, C, Tippy who had been an instructor for about three years. The 1933-3^ Register includes M. S. Ketchum on the staff for that year. He was placed in this position when it became necessary for him to resign from the position as Dean because of ill health. He did not recover but died in 193^ after a distinguished career. How- ever, this career was not as a member of the civil engineering staff so is not pertinent to this discussion. The person who was in training to succeed Professor Cross was Professor T. C. Shedd xijho had his undergraduate work at Brown University under Professor Cross and vrho \-jrs brought to the Uni- versity of Illinois in 1922, upon the recommendation of Professor Cross, to teach structural courses. Professors Cross and Shedd were intimately associated for 15 years at the University of Illinois and for two or three years at Brown, As a result of this close association Professor Shedd became more familiar with Professor Cross' philosophy and methods of analysis than any other person. To these, he has added his own which are very important. Being a younger man than Professor Cross, he is in position to carry on for a longer period in the future. Professor Shedd has had exten- sive experience in structural design and is often called upon by practicing engineers for assistance when difficult problems are encountered. His writings are notable because of his thorough appreciation of actual design as well as theory. Professor Cross depended upon him to provide instruction in this phase of structural engineering. Professor Shedd is known as one of the best teachers in the College of Engineering and one of the best teachers of structural engineering in the country. He is joint author, with Professor Vawter of this Department, of a book entitled "Theory of Simple Structures" which was published in 1931. Immediately this book assumed leadership in this field as evidenced by being more widely adopted as a text than any other book. His book on "Structural Design in Steel" which was published in 193^1-, has met with equal success. Work is far advanced on the manuscript, which he is preparing, for a book on "Bridge Design" and which already has been accepted for publication. He has carried on extensive research in the economic phases of structural design. -4- Professor Shedd ably fills the vacancy left by the resignation of Professor Cross but in addition, the outstanding work in this field by Professor N, M, Nev/mark must be considered. In:4ci''in'.t.ely "fter graduation, with special honors, at Rutgers University in 1930, Mr. Newmark was appointed a Research G-raduate Assistant in our En{3ineering Experiment Station where he worked for two years under Professor W. M. Wilson. He continued with graduate work and was awarded the doctor's degree in 193^* During this period, his work was directed by Professor Cross but he continued his studies under Professor Wilson and also studied under Professor Westergaard. His work with all of these men was so outstanding that Professor Wilson recommended that a permanent position be created for him on the civil engineering staff of the Engineering Experiment Station. In a letter of recommendation for this appoint- ment Professor Cross states that, "He is, I think, the ablest man we ever had in graduate work. He has a great power for originating methods and viewpoints." Professor Westergaard expressed his opinion of Dr. Newmark as follows: "I believe that his appointment will be a contribution to the solution of the difficult problems of future distinction of the University. His intellectual capacity is rare, his personality attractive. He is among the few who can be rated as truly brilliant." The appointment was made. He was given no definite assignment but was free to select his own work and carry it on as he pleased. That this policy was a v/ise one is evidenced by the remarkable work he has done since his appointment in 193^^ a part of which has resulted in the publications listed later in this memorandum. Dr. Newmark, although still a young man, has won considerable distinction and is already recognized as one of the country's outstanding men in his field. In a recent letter to Dean Enger, Mr. E. F. Kelley, Chief of the Division of Tests of the Public Roads Administration, who has a wide acquaintance among structural engineers, made this comment concerning Dr. Newmark: "In connection X'^rith the investigation of concrete floor gl'0,bs that is being conducted at the University I have had an opportunity to obtain a personal knowledge of his ability. In my opinion he is one of the outstanding men in the United States in the field of research in which he is enga^/jed. In fact, I do not know of anyone else who has the unur^u,'»i- to'^chnical ability that is required by this difficult research and at the same time the thorough appreciation of practical considerations that is necessary to the successful utili- zation of its results." He is nox^r serving as Consultant to the following organizations: The Committee on Passive Protection Against Bombing of the National Research Council; the National Defense Research Committee; and one of the builders of concrete ships for the Maritime Commission. In relating the work of Pro- fessor Nei^/mark to the general theme of this memorandum -it should be kept in mind that the position he occupies did not exist before I93J+ and that his appointment, therefore, represents a development in the department which has taken place entirely during the period in question. ''iC -5- The vacancy created by the resignation of Professor F. W. Stubbs was filled by the appointment of Mr. H, P. Evans, who graduated at Carnegie Institute of Technology in 193^, where he ranlted first in his class and was the recipient the annual award of the Pittsburgh Section of the Anerican Society of Civil Engineers for being the most oustaHcllng civil engineering student. "'"'^ " letter of recommendation, Professor McCullough, Head of II' in a the Civil development. had," After securing his master's degree, with the U, S. Reclanation Bureau i-^here he Engineering Department at that institution stated that: "In my opinion he possesses to a marked degree intellectual capacity and promise of future development." Professor Geckeler of that in- stitution wrote that: "Ho has the capacity for growth and should draw attention in the future." Immediately upon graduation, he was awarded a research assistant ship at the University of Iowa and was granted the master's degree in 1933* Professor Sherman Woodward, under whom he studied, wrote that he had "the highest opinion of his ability both as to intellectual capacity and promise of future I consider hira about as good as any student we ever i^ --i-^-^-- he obtained a position -. .-. -, had three years of ex- perience in the design of hydraulic structures. l^.Ifctner, in charge of dam design stated that "Mr, Evans came to the Bureau with an unusually good education and highly recommended. He has ful- filled all expectations in a variety of assignraents given him and is considered one of our most valuable younger engineers." 1^. Rockwell, his immediate superior stated that: "It has been my privilege, for more than thirty years, to work with and supervise young engineers, I have never encountered a young man who, in my opinion, showed more promise in engineering work than Mr, Evans. He has had a great variety of assignments, all of which have been completed with the utmost satisfaction both to me and to those in higher positions. He has specialized in hydraulics and has an ex- tremely good understanding of the subject. However, the structural problems given him have been handled just as well as hydraulics. He is a splendid draftsman, a very industrious worker, and has to an unusual degree the ability to grasp the vital points of a problem and to arrive at a correct answer by clean straight thinking His intellectual capacity is of the highest order and in ray opinion he holds the greatest possible promise for future development." Finally, Mr, W, H, Nalder, Assistant Chief Designing Engineer in Charge of Personnel, stated that "I can highly recommend Mr, Evans as being a young man of exceptionally high intellectual capacity and technical ability he is outstanding among our younger engineers and I know of no one better qualified for an instructor- ship in civil engineering or who in my judgment has better promise for future development." In appraising the last statement it should be kept in mind that the Reclamation Bureau em.ployed nearly a thousand engineers at the time this statement v/as made and that a large proportion of these were young m.en. These comments emphasize Mr. Evans' natural ability, excellent training and promise of future development. During the six years he has served as a member of this staff he has entirely justified the opinions which have been expressed. vK"' '\ -6- Also, during the Intervening summers he ^las taken the opportunity to broaden his contact with actual engineering work by securing employment with engineering organizations such as the American Bridge Company and Greeley & Hansen, Consulting Engineers of Chicago, Men in these organizations have spoken enthusiastically of Mr. Evans as a man ard ^s an engineer. By filling a vacancy with a man of this caliber, it seems certain that the department has maintained its standing, Mr, J, G-, Clark was appointed as instructor in 193^ "to fill the junior position in the department which had been occupied by Mr. Tippy. He graduated at the University of Illinois in 1935 and was awarded the master's degree in 1939* At the time of his appointment he was v;ith the U. S. Bureau of Reclamation. Since Mr, Clark graduated at this institution and his qualifications were v/ell known to us, no letters of recommendation were required. For that reason, comments from others are not available as they were in Mr. Evans' case. Hov/ever, Mr, Clark made an outstanding record as a student and showed great promise of development. He has made a fine record. Professor Shedd recently stated that Mr, Clark gave promise of developing into a man who could be placed in charge of structures when he retires l6 years hence. I'lr. Clark lias used every opportunity to improve his preparation for his position. During the school years he has carried on an exhaustive research program on the "Development of Design an.d Fabrication Specifications for Iron and Steel Structures" and has given considerable time to the study of the "Stability of Hydraulic-Fill Dams." The results, to 19^0, of the first investigation were issued in mimeographed form to cOO r^tructural engineers. Eventually, this investigation will be published as a Bulletin of the Engineering Experiment Station, Mr, Clark has devoted each suLiraer to securing experience which would improve his teaching. The positions have been so selected as to give him well-balanced ejcperience as evidenced by the following list of positions for six summers: Designer and detailer of reinforced concrete structures with the U, S. Reclamation Bureau in Denver, Colorado Detailer and calculator of steel structures with the American Bridge Company at Ambridge, Pennsylvania Designer of steel bridges with the Bethlehem Steel Company, Eetlilehem, Pennsylvania Designer and estimator of steel structures with the American Bridge Company at Pittsburgh, Pennsylvania Bridge designer with Howard, Needles, Tammen, and Bergendoff, Consulting Engineers, Kansas City, Missouri Structural analyst on airplanes with the Cur tiss- Wright Corporation at Columbus, Ohio '■-^m. m -7- Mr. A. A. Brielraaier Joined the staff as an Associate in 1937, He was awarded the degree of Bachelor of Science by Case School of Applied Science In 1926 and the degree of Civil Engineer in 1929. He came to the University of Illinois In 1929 as a graduate student and was awarded the degree of Master of Science In 1930* ^^^ 1930-31 he studied at Technlsche Hochschule Danslg on an Inter- national Exchange Fellowship. During the suramer of 1931, he studied at the University of Geneva in Switzerland. In September 1936» he returned to the University of Illinois to continue his studies toward the degree of Doctor of Philosophy. He has continued work toward this degree on a part-time basis since Joining the staff. For the last year and a half, he has been on leave of absence with the U. S. Army Engineers. He has had very extensive experience in structural engineering with the U, S. Array Engineers and several firms of consulting engineers. He reads and speaks German readily and reads French. He has made many technical translations from the Engineering Library and is the author of a "German- English Glossary" published by the Engineering Experiment Station. His research has been devoted to his doctor's thesis on "Buckling of Compression Members". Mr. Brielmaler is an experienced structural designer who is extremely well qualified for teaching in this field. The work of the department has been strengthened since 193^ by the addition to the staff in September 19^1 of Mr. A. E. ' Cumralngs and Dr. Ralph B. Peck as Lecturers in Foundation Engineer- ing and Soil Mechanics, respectively. Each of these men spends two days a month on the campus giving lectures in regular courses, advising x>rlth members of the staff on research projects and discuss- ing with them the various developments in their fields. Mr. Cummings is one of the foremost foundation engineers in the country. He is invited to present papers at nearly every conference on soil mechanics and foundations which is held in this country. He has lectured at ten universities during the past five years and has been on the staff of the Graduate School of Engineering at Harvard Uni- versity as Lecturer on Foundation Engineering since 1939» However, his association i>rlth the University of Illinois is much more exten- sive than with Harvard. Mr, Cumralngs has contributed many Important papers to the Transactions of the American Society of Engineers, the Proceedings of the Highway P.esearch Board, the Journal of the Boston Society of Civil Engineers and other technical publications. He has recently been appointed as a meraber of the Executive Committee of the Soil Mechanics and Foundation Division of the American Society of Civil Engineers. field Renss and s slty with under Karl Dr. Peck is a young man who has won distinction I in his at an early age. He was awarded the bachelor's degree by elaer Polytechnic Institute in 193^, the doctor's degree in 1937 tudled at the Graduate School of Engineering at Harvard Univer- in 193^39. He has had e^xpferience in f^tructural steel design the American Bridge Company and in foundation investigations Dr. Arthur Casagrande of Harvard University.

Mr. Cummings and Dr. Peck ing as Lecturers since September 19^1 • The position .

Development of Staff Since 191^ . — Since the 13 members of the staff, who have not yet been mentioned, v;ere here before 193^, it seems unnecessary to prolong this memorandum by discussing the qualifications of these men. The pertinent considerations are those which indicate the effectiveness of each man in 19^2 as compared with that in 193^» *^^ course, the most important consi'^.eration is his developm-ent as a teacher. It is impossible to present tangible evidence of this. From frequent comments of students and graduates, it seems certain that the teaching done in this department is ex- cellent. Hov;ever, since it is relative effectiveness in 19^2 and 193^ that is under consideration, it seems possible to present tan- gible evidence concernin-- this pha.se of the department's work. All of the staff members in this group have continued to develop since 193^» In some cases this development has been very marked. Evi- dence of such development is given later in this memorandum. The arrangement of statistical material given later in this memorandum is approximately in the order of position in the depart- ment. .'iM -?- 3. • SPECIAL DEVELOPMENTS AND ACTIVITIES This section of the report is devoted to developments in the work of the department fror.i 193^ to 19^2 which Beem to warrant special comment. The developments which have occurred in the curriculum are -presented. The entire research program is included because it is not possible to separate the normal work from that which might be considered as special, however, as noted elsewhere the research program for the past nine years is double that of the preceding nine-year period, which in turn represented a considerable increase over the period which preceded it. The expansion in re- search has been very marked. The assistance which the departm.ent has rendered public agencies during the last nine-year period is quite outstanding. There was little activity of this type during the preceding nine-year period. Such a condition m.ight be expected in a staff which is developing and is becoming more generally recognized as the staff members become more experienced. The material on this subject will be arranged in four groups as follows: a. Development of Curriculum b. Developments in Research c. Assistance G-iven Public Agencies d. Conferences and. Short Courses a. Developm.ent of Curriculum Public Health Enfi-ineerlnp . — Beginning with the current school year a new curriculum leading to the degree of Bachelor of Science in Public Health Engineering has been added to the curricula administered by the Civil Engineering Department. This curriculum is offered to meet the increasing demand for engineers trained in this field. The studies during the first three years are the same as those required of all students in civil engineering. During the fourth year, specilization is started in sanitary engineering and at the end of that year the degree of Bachelor of Science in Civil Engineering is awarded. The first semester of the fifth year is devoted to biological and chemical science and publid health engineer- ing while the second semester is spent at the College of Medicine in Chicago taking specialized work in the Department of Bacteriology and Public Health. The Civil Engineering Department tias the enthus- iastic cooperation of the State Department of Public Health in this curriculum and in placing its graduates. H. E, Babbitt, Professor of Sanitary Engineering, is in direct charge of the curriculum. Aeronautical Option . — Beginning with the current school year, the civil engineering curriculum includes a senior option cover- ing the aeronautical phases of civil engineering including aero- dynamics, the structural design of airplanes, airport design and aerial navigation. This option is built on a strong basic training in structural analysis and design including statically indeterminate structures, and includes the application to the design of airplanes and hangars. It develops the principles of drainage and highway de- sign and applies them to the drainage of airfields and the construe- ' tion of runways. The Department of Electrical Engineering is cooperat- ing in providing instruction on airport illumination. The department is well manned for such an option with Professor Shedd's specialized knowledge of statically indeterminate structures and space frames, Mr. Clark's knowledge of indeterminate structures and experience with \m^\ -10- Curtiss-Wright Corporation in airplane design, Professor Crandell's experience in airport layout and design, Professor Doland's ex- perience as consultant with the U, S, Army Engineers in the con- struction of the Caribbean Bases, Professor Newnark's specialized training in the theory of elasticity, and Mr, Dell's experience in navigation with the U. S. Coast and G-eodetic Survey and in teaching navigation in the Civil Aeronautics program. There has been a strong demand for civil engineers in aeronautical engineering and many of our graduates have secured positions in this field, some of considerable responsibility. G-reat developments are taking place during the war period and it is expected that there will be intense activity after the war. However, there is a possibility that, when peace returns, the supply of aeronautical engineers will be greater than the demand. If that is the case, the graduates from the aero- nautical option can readily enter other phases of civil engineering. The training value of courses in aeronautics is high and student interest in this field is acute. These factors are brought together in the aeronautical option. Railv/ay Option . — In 19^0, the Department of Railway Engineering was dissolved because of its very small and declining registration and the resultant high cost of instruction. The various curricula offered by that department were placed in the Departments of Civil, Mechanical, and Electrical Engineering:. In the Civil Engineering Department, a Railway Option was added to the senior option. The small registration in railway engineering can be ex- plained, partially at least, by the fact that universities do not usually have Railway Eni.:ineering Departments, so the existence of such a department would not be known to many incomdng students and by the fact that it required the selection of a very specialized field at the beginning of the sophomore year xi^hen students usually have not made up their minds on the specialized field which interests them most. Ma '■-•Xv-" ■'-■ lis It is hoped that by placing the railway courses as senior options or electives in the major engineering curricula the interest In such work will increase. These courses have a much larger body of students to draw upon than they did in a small department of railway engineering. The renewed interest in railways on the part of the public, the recent developments in railway transportation, and the improved financial condition of the railways should result In greater opportunities in this field and a resultant increase in the enrollment in railway courses. « Soil Mechanics and Foundation Engineering . — During recent years, there has been a large and growing interest in soil mechanics and foundation engineering due largely to the work of Dr. Karl Terzaghi. As a result of this interest, many schools are offering courses in soil mechanics. Difficulties are encountered, however. -11- because the field is full of uncerta suitable textbooks have not been ava all, the subject cannot be presented not had extensive field experience, of the courses now taught In univers phase of this subject and it is some tory course in soil testing is a cou point of view is strongly objected t Terzaghi and Dr. Casagrande who are this field. inties, is developing rapidly, liable and, most important of adequately by persons who have Such persons are scarce. Most ities emphasize the laboratory times considered that a labora- rse in soil mechanics. This by such authorities as Dr. the two leading authorities in This department has been active in developing work in soil mechanics and foundations on a conservative basis. It has a well equipped laboratory and offers elective undergraduate and graduate courses in "The Properties of Soils" but not "Soil Meclianics", taught by Professor E, E, Bauer who is an experienced laboratory teacher. He has had special training under Dr. Terzaghi, The undergraduate and graduate courses in " Earth and Masonry Structures" including foundations, have kept pace x^rith the develop- ments of basic principles which apply to such structures. These are taught by Professor W. C. Huntington. In order to obtain intimate contacts with field investiga- tions, Dr. R. B. Peck anrl i^", A. E. Cunnings have been ado'.ed to the staff as Lecturers in Soil Mechanics and Foundation Engineering, respectively. The qualifications of these men are discussed in the section on "Changes in Staff" so vjill not be repeated. They are recognized as outstanding authorities in these fields. These men lecture in re(;^lar courses and advise on research. To supplenont their lectures, series of lectures were given last year by Dr. Karl Ter- zaghi and Dr. Arthur Casagrande of the G-raduate School of Engineering of Harvard University; Dr. Ralph E. G-rim and Dr. George E. Ekblaw, of the Illinois Geological Survey; Mr. Louis Berger of the U. S, Army Engineers; and members of the civil engineering staff. It is planned to continue this arrangement. Emphasis is placed on the behavior of soil in the field as evidenced by actual engineering " /rather than on the laboratory phases of soil testing. Dr. Casagrande has stated that ninty per cent of the latoratory tests which have been made on soil samples might better never have been made because they are misleading and, therefore, dangerous. Dr, Terzaghi, who is thoroughly familiar with the instruction which is being given in this subject throughout the country, strongly endorses the program at this institution. Plans are underway for further development. -12- b. Developments In Research Two members of this department are on the research staff and devote their time chiefly to research although each teaches a graduate class. These are Research Professor W, M, Wilson and Research Assistant Professor N, M, Newmark. A special appropria- tion of $3)000 has been made each year since 193^ ^o^ sewage re- search. This is assigned to Professor H, E. Babbitt* Other smaller appropriations are made for research in general. Many teaching members of the staff are engaged in research but this work is less extensive because their major task is teaching. A large proportion of the funds for research are provided by outside agencies as stated elsewhere. The facilities for research in this department are un- surpassed and are improving. An inspection, of these facilities, located chiefly in Talbot Laboratory, would-be very convincing. Appropriations have been made and plans have been prepared for a new Sewage Research Laboratory. By avoiding all critical materials in the plans, the approval of the War Production Board for the erection of this building was secured. It is expected tliat con- tracts will be awarded very soon. Statistical information concerning the activity in re- search for the nine-year period 193^ "^o 19^2, as compared with the nine-year period 1925 to 1933* is given on pages 27 to 32 of this memorandum. These will not be repeated but they show that, both in number of publications of the Engineering Exi-oeriment Station and in amount of money provided by outside agencies for research, this activity has doubled in the last period. The object of this section is to rive some idea of the magnitude, character, and scope of the research programs of this department. Most of the projects mentioned have' progressed to such a stage that results have been published, one or two arc about ready for publication, and one which is far advanced is mentioned. No projects which are not extremely active are included although many such are underway in the department, their progress being determined by the time available for research on the part of teaching members of the staff. Only the projects which were active during the last nine-year period are mentioned. Welding Research . — Several projects on structural welding have been carried on by Professor W, M, Wilson during this period and several Bulletins giving the results secured have been issued. Others are underway. All of these were undertaken to answer ques- tions which have been brought up by engineers because of the trend fron riveted to welded structures. One investigation was carried out for the Railxfay to determine the effectiveness of increasing bridge members by welding additional metal to them. Nickel Plate ' the size of Many perplexing -13- problems were Involved. The results secured were vital, conclusive and of great value to the profession because one of the important problems of the railways is that of increasing the capacity of existing bridges to carry the greatly increased loads which are being placed upon them. riveting has been adopt ( of the reeling that wel( repeated loads, usually particularly interested Fabrication of steel structures by v/elding instead of d reluctantly by engineers partly because ed joiJ^'ts would have low resistance to called fatigue. The U, S, Navy is in this investigation to secure information for use in the design of welded warships. Because of these con- ditions, the Engineering Foundation sponsored an extensive inves- tigation by Professor Wilson xi^hich was begun in 193^ and has been financed through 19^3 on the basis of an expenditure of $10,000 per year. Two Bulletins have been published on this research and pre- liminary drafts of two additional Bulletins have been written. It is expected that base specifications for welded steel structures will be formulated from this research. The organizationsproviding the funds are: The Public Roads Administration, the Chicago Bridge and Iron Company, the Bureau of Ships of the U, S, Navy, the Asso- ciation of American Railroads, and the Aetna Iron and Steel Company. Professor Wilson was av/arded the Chanute Medal of the Western Society of Engineers for a paper on his welding research. There has been a trend toward the use of low-alloy structural steel having a static strength sOInex^rhat greater than that of the usual structural steel. Little was known of the comparative effectiveness of riveted and welded joints made of the two classes of steels. This investigation has provided important information on these subjects which has been published as a Bulletin. Fatigue Tests of Riveted Joints and Connections . — The possibility of failure of metal after many repetitions of a load considerably belov; the static strength of the metal has been known for many years and tests have been made on small machined specimens. Only recently, there was a realization that fatigue tests of small machined and polished specimens gave no dependable indication of the fatigue strength of structural members. Professor V'ilson undertook an investigation to obtain information on this subject which would be of use to structural engineers. Fatigue machines with much greater capacity than any which had yet been constructed were designed and built. The investigation gave such startling results that restrictions have been placed on the use of low-alloy steels for members subjected to fatigue until further tests can be made. The San Francisco-Oakland Bay Bridge authorities were so interested in this investigation, because of problems which developed on the design of that bridge, that they provided the funds to carry it through. The results have been published as a Bulletin. -m- Because of the many failures of rivets in the connection angles in the floor systems of steel railway bridges, an investiga- tion was made by Professor Wilson of the fatigue strength of such connections. The results which were published in a Bulletin f-.^rr.jf"'. the basis of a new rule of design incorporated in the Specifications for Steel Railway Bridges of the American Railway Engineering Association, Reinforced Concrete Arch Bridges . — Many multiple-span reinforced concrete arch bridges are constructed but there are many uncertainties involved in the design of such structures. These have required that assumptions which are known to be safe be made. Investigations extending over several years were made by Professor Wilson and completed in 1935» "^^e results secured were significant. They were published in three Bulletins and were presented at the annual meeting of the American Society of Civil Engineers in a paper entitled "Laboratory Tests of 1^.1 tiple- Span Reinforced Concrete Bridges" on v/hich he was av/arded the J. Jcmes R. Cross Medal of that society in 193^* -^s stated in the rules for this award, "The medal shall be awarded to a paper which shall be judged worthy of special commendation for its merit as a contribution to engineering science."

The results r presented before the ts on Rigid Frame Bridges" The medal is awarded worthy of special commen- on was financed by the Cylindrical Shells and Thin Spheres . — Because of the developments in the art of welding, it has become feasible to use the welded tube as a structural member. Two investigations have been made by Professor Wilson on such members, the results of which are published in Bulletins. These have added r.i-tcri"lly to the knowledge of the behavior of such members when usedrs colur.n'^ rnC in flexure. The results have recently proved of particular significance in the design of certain war weapons and will probably lead to another investigation. Large steel spheres are being used for the storage of gas under pressure in place of the older type of gas holder. A significant investigation of such structures was made by Professor Wilson and published in a Bulletin. These investigations were financed by the Chicago Bridge and Iron Company, -15- Flow of Sludges In Pipes . — In construction, in excavation, In various industrial processes, in the purification of v;ater and in the treatment of sewage it is often necessary to pump through pipes mixtures of liquids and solids. An experimental and analytical in- vestigation was undertaken by Professor Babbitt to develop pro- cedures for determing the power, pipe sizes and head losses which pertain to these operations. The investigation was by far the most complete of any ever carried out. A method was developed which permits the computation of the various factors involved and permits designs to be made with certainty. Some of the applications are the pumping of powdered coal, wood fiber in paper manufacture, concrete chemicals in the chemical industry. The results, in two Bulletins, have been enthusiastically re- Another significant investigation carried on deals with the mechanical aeration of sewage. in construction and which are published ceived by engineers, by Professor Babbitt The results of this investigation v/ere published in a Bulletin. Flood F10V7S of Illinois Streams . — In the design of the spilli^ray for a dam, the water opening under a bridge or through a culvert, the size of a storm sewer, the height of a levee, and many other engineering works associated vjith vrater, a fundamental assumption must be made as to the maximum quantity of water which the structure must discharge in a unit of time and the frequency with which such a discharge may be expected to occur. The frequency of a given discharge is of importance because, if it may be expected to occur only ^nce in a long period of years and if loss of life is not involved, it may be more economical to repair the damage^ than to spend the sums required to avoid the damage. This investigation which was made by Professor George W. Pickels, contains an analysis of the flood-flow data on 2^ Illinois streams. It required many years of careful and skilled study and analysis. The results which are of major importance are published in a Bulletin. Slab Investigation . — In 193^, representatives of the U. S. Public Roads Administration and the Illinois Division of Highways requested that the Civil Engineering Department undertake an in- vestigation which would remove some of the uncertainties associated with the design of reinforced concrete floor slabs for highway bridges. Since the Department of Theoretical and Applied Mechanics was also interested in this phase of research, a cooperative agree- ment between the various agencies which have been mentioned was entered into. According to the terms of this agreement, the out- side agencies would provide |20,000 per year for this investigation. Professor Frank E. Richart of the Department of Theoretical and Applied Mechanics was placed in general charge of the project and of the laboratory tests, and the analytical studies were assigned to Professor Newmark. The investigation has been continued with^a total expenditure to date by the outside agencies of about |100,000 and has yielded very valuable results, which have been published in several Bulletins of the Engineering Experiment Station. Mr. E. F. Kelley, Chief of Division of Tests, of the Public Roads Administra- tion, in a letter commenting on a recent bulletin entitled "Moments '.<-' -16- in I-Beam Bridges" "by N, M, Newmark and C. P, Si ess, stated that the results in this bulletin alone are worth the entire cost of the investigation to date. This is a rather striking statement but when one considers the extremely large expenditures on highway bridges throughout the country, information which permits engineers to design with greater certainty and economy is of great economic value. In any case, this comment, together with the fact that this investigation has continued so long and that there is no thought of discontinuing it, is evidence of the value of the in- vestigation to the designers of highvray bridges in this state and throughout the entire country. The participation of the U. S. Public Roads Administration in this investigation insures the general adoption of the procedures developed. Three Bulletins, with Pro- fessor Newmark, as senior author, have been published and four by others associated with this project. Foundation Pressures . — In predicting the settlement of buildings and other structures founded on clay soils it is necessary to compute the intensity of the vertical pressures introduced into the soil by the weight of the structure and the loads it carries. Assumption must be made concerning certain physical properties of the soil. When this has been done the vertical pressures can be computed. This was a very laborious procedure before the Circular by Professor Newmark was published. In this publication, a method is given which reduces the time required from hours to minutes. This has resulted in the universal adoption of his procedures. The method developed for this purpose has been extended to the calcula- tion of the intensity of the stresses in any direction as well as in the vertical direction. A Bulletin covering these further developments is in press and will be available soon. War Investigations . — An extensive research project dealing with the war effort, v;hich is confidential in nature and, therefore, nannot be described, is being conducted by Professor N. M, Newmark of this department and Professor F. E. Richart of the Department of Theoretical and Applied Mechanics. The importamce of this investi- gation is indicated by the annual appropriation of ^20,000 which is being made by the Federal agency for whom the work is being done. A description of this investigation cannot be given at the present time. Simultaneous Eq uations . — Many problems in science and engineering involve the use of quantities determined by means of simultaneous equations whose constants are subject to error or variation. Examples in the field of structural engineering occur in the analysis of continuous frames. A similar situation exists in connection with the determination or the interpretation of ex- perimental data, if equations which are subject to observational errors or physical variations are involved. A mathematical inves- tigation carried out by Professor George H. Dell dealt with the effects of such errors. This was published as a Bulletin entitled "The Effects of Errors on Variations in Arbitrary Constants of Simultaneous Equations." -17- Economlcs of Structural Design . — Investigations extending over many yec^.rs by Professor economics of structural desi for the design of steel stru frames, continuous trusses, bridges, reinforced concrete building frames. The result of "Structural Design in Ste and Erection of Steel Bridge prepared and which has been T, C. Shedd have dealt x^^ith the gn and the development of specifications ctures. These deal with steel rigid steel-roof framing, steel railway bridges and continuous saw-toothed s will be published in the new edition el" and a new book entitled "Design s" for which the manuscript is being accepted for publication. Bridge 5fiecificationa « — An exhaustive study of the origin and development of specifications for iron and steel bridges is being carried on by Mr, James G-, Clark. He has assembled what is probably the most complete collection of bridge and building speci- fications available anywhere. The results of his investigation to 19^0 were duplicated in mimeographed form and sent out to over 60O structural engineers to obtain their comments and suggestions and any additional information which they might be able to provide. Timber Investigations . — Investigations on the load dis- tribution by laminated timber floors, the streases in glued laminated timber arches and the strength of glued laminated wood beams impregnated with creosote have been carried on by Professor W, A. Oliver. The results secured have been partially published in the Year Book of the American Railway Engineering Association and the Proceedings of the American Society for Testing Materials. Study of Cement Prices . — Shortly after Governor Horner took office he was confronted with some problems growing out of what looked like an excessive increase in the prices bid for furnishing cement on the stats highways. He asked the President for a committee to study the matter, consisting preferably of an accountant, a con- crete man, and a road man. Professors H. T. Scovill, F. E. Richart, and C. C. Wiley composed the committee. After meeting with the Governor, Professors Scovill and Richart visited a number of the leading cement mills east of the Mississippi where the former studied the cost records and the latter the technical operations. Meanwhile Professor Wiley devoted attention to the relation of cement prices to pavement costs. A confidential report was presented to the Governor which apparently resulted in a material reduction in the bid prices and set up a price range that appeared satisfactory to all concerned. jgibility of the plates. Several copies of the report were supplied to the Secretary of State. The result was the retention of the straight numerical system for passenger cars which the studies showed to be the simplest, most rapid and accurate to read, and most free from mistakes in reporting. At the same time it resulted in a redesign of the numerals and their arrangement for greater legibility. Conducted by Professor Wiley. -IS- Study of Road 51p:ns . — These studies were carried out v/ith the full cooperation of the Illinois Division of Highways. They related to the height of signs, the size of signs, the design of legends, the spacing and arrangement of reflector "buttons, location of signs, etc. Findings were reported from time to tine infernally to the Division of Highways and several conferences were held. These studies resulted directly in the adoption of the present height of Illinois road signs. They played an inportant part in the final design of the railroad prewarning sign which has becone part of the standard code adopted by the Anerican Association of State Highway Officials. They had influence on many of our sign details with respect to size, legend and reflectorizing. Conducted by Prof. Y/iley. Stabilized Soil . — Earth has been extensively used through- out the world as a material for the walls of small houses and other buildings. Faniliar examples are the adobe houses in the Southwest, In that arid region, little difficulty is experienced with the effect of moisture on such walls but in regions of heavier rainfall earth is not a suitable naterial for this use unless it is treated to make it resistant to noisture. In an investigation by Professor John S, Crandell and Edwin H, Hansen, emulsified asphalt v/as used for these purposes. The results secured have extended the possible use of this low-cost building material. They were published in a Bulletin by Mr, Hansen, The interest in this investigation has been very widespread. Pressures due to G-ranular Materials . — Since 193^> s-^ ir^~ vestigation of the pressures exerted by granular materials such as wheat, corn, soybeans, sand and cohesive soils has been underway in the department under the direction of Professor W. C. Huntington. When the project started, no reliable device for measuring such pressures had been developed although many investigations had been carried on in various parts of the world using many tjTpes of pressure measuring apparatus which have been shown to be defective. The re- sults secured are therefore of questionable value. By ISjG a pressure cell had been devised which greatly reduced these objectionable characteristics and was satisfactory for the experiments on pressures in model and full-size grain bins which were underway. In about 1939, the U. S, Reclamation Bureau started an Investigation of the pressures exerted by earth on retaining walls and on conduits and control works buried in earth dans. After investigating the various types of pressure neasuring devices, the pressure cell developed here was adopted, thoroughly tested under widely varying conditions, and adopted for use in the retaining wall investigations and for in- stallation in various high earth-fill dans. More recently the Panama Canal engineers have installed such cells in structures which are now being built. Satisfactory performance has been reported. In 1939, the Illinois Division of Highways requested the cooperation of the department in an investigation to determine the pressures exerted on rigid culverts through earth embankments. A field installation of two types of pressure cells was made in a large -19- relnforced culvert bein[: constructed near Peoria where the earth fill over the culvert was over kO feet deep, A cooperative agree- ment was entered into. A major part of this investigation was the testing of all known types of pressure cells under controlled con- ditions so that their accuracy could' be determined. This is now underway and has yielded significant results. The type of pressure cell most commonly used throughout the country before this investi- gation started has been shown to give results which are seriously in error. The investigation is continuing at a cost of about $1500 per year and is financed principally by the Division of Highways. Joints in Concrete Pavements . — The practice of installing Joints in concrete pavements to provide for the movements which take place when temperature and moisture conditions change, and to re- lieve the stresses which occur, is as old as the modern hard- surfaced road itself, A large amount of investigational work has been done by various agencies throughout the country. In about 1930 a type of Joint, called the air-cushion Joint, was developed which gave promise of giving superior results and v/hich appeared to Justify the large expenditure of about ^3,000 per mile of pavement for the Joints only. This type crnie into quite extensive use in spite of its cost. When it vras not used, the reason was primarily the cost, because most engineers considered it to be the best tjrpe of Joint available. In 1937 at t-ie request of the G-overnor of Illinois, University of Illinois, through the Civil Engineering Department, began an investigation of joints in concrete pavements to supplement the investigations of the Division of Highways. This assigned to Professors J, S, Crandell and C. C, Wiley Engineering Department, Professor F. E. Richart of Theoretical and Applied Mechanics, the former department as chairman, investigations investigation. the artment to task was of the Civil of highway was set up the Department of and Professor W. C. Huntington of The investigation involved field in many parts of the country, extensive laboratory and conferences with many highway engineers and groups long In engineers. One experimental section several miles in a highway which was being constructed in 1935* this section 21 types of Joints were installed. This included all of the significant types then in use or proposed. They were in- stalled under the supervision of representatives of the Joint manu- facturers so that no objection could be raised to the results on this basis. The behavior of the Joints in this section vjas observed at intervals and will continue for an indefinite period in the future. The results of and have had a pronounced country.

The significance -20- of this investigation will be appreciated when it is known that the annual expenditure in this country for this type of Joint ran into the millions of dollars. The conclusiveness of the findings is in- dicated by the fact that the manufacturersof the air-cushion Joint accepted the situation with very little protest even though it closed the market for this product and caused the abandonment of manufacturing facilities costing many thousands of dollars. The results of the investigation are to be published in a Bulletin of the Engineering Experiment Station under the Joint authorship of members of the staffs of the University and the Division of Highways. The manuscript for this Bulletin is nearing completion. The investigation was financed by the Division of Highr- ways. This involved a direct payment to the University of $10,000 and an indirect cost to the Division of Highways of several times that amount due to services rendered by members of its organization and materials furnished. Hydraulic Model Tests . — Model tests were made to determine the hydraulic characteristics of the spillway at West Frankfort, Illinois. These tests were the first of a series which were intended to include studies of all of the impounding reservoir spillways in Illinois. The tests made were successful in determining the probable flood capacity of the spillway and indicated certain changes which should be made to insure the safety of the structure. The general program had to be postponed on account of conditions but will prob- ably be resumed in the post-war period. This work was directed by Professor J. J. Doland, Study of Dolomites in Chicago Area . — An investigation of the dolomites in the Chicago area is being made by Professor E. E, Bauer in cooperation with the Illinois Division of Highways and the Illinois Creoiogical Survey. This investigation has as its main ob- jectives the determination of the durability of these stones for masonry construction, concrete aggregates and for use in sewage filters. The investigation is practically complete and will form the basis for a Bulletin. Particle Size Determination . — One of the important tests used in classifying soils is tliat for particle size. The sizes of the larger particles can be determined by sieve analysis but the sizes of the smaller particles cannot be determined in this way. The usual procedure makes use of the hydrometer and calculations based on Stokes' law. Professor E. E. Bauer has made investigations of this procedure and has developed and improved the technique for com- puting the particle si^e from the hydrometer test data. He has also pointed out the effectP/flocculation on the results secured. The re- sults of this investigation have been described in the Engineering News-Record, the Proceedings of the American Society for Testing Materials, and the Proceedings of the Purdue Conference on Soil Mechanics and its Applications. -21- c> Assistance Given Public Agencies Introduction . — There Is no distinct line of demart; atlon between the research program and the assistance which has been rendered to public agencies. For example, much of the research which has Just been described was for public agencies or quasi public agencies such as the railroads. This Includes such organizations as the United States Navy, the Public Roads Administration, the Illinois Division of Highways, the Association of American Rallxvays, the American Rallv;ay Engineering Association, the San Francis co-Oakland Bay Bridge Authority, and others. In the paragraphs which follow other actlvltes of the staff which were undertaken at the request of various public agencies will be described. The Important considera- tion Is, of course, the results achieved and not the classifications followed. Tacoma NarroTifs Bridp:e . — Professor W. M. Wilson was engaged as an engineering expert In connection with the Tacoma Narrows Bridge failure. This bridge, which failed after being in service for only a few months, was Insured for more than five million dollars. Be- cause of the large sum involved, the insurance com.panles appointed a board of engineers to determine an equitable basis of settlement for the loss. Professor Wilson was appointed a member of this board. After the failure, major portions of the bridge remained in place and the extent of the loss depended primarily upon whether or not it would be good engineering to Incorporate these standing parts in a new structure in view of the fact that they had been subjected to some local overstress. The appointment of Professor Wilson to membership on this board was a recognition of his standing as an authority in the field of the damaging effect of an occasional over- stress in localized sections of structural members, a field that has become recognized as one of growing importance. Highway Finance and Administration . — The Illinois Hlghx^ay Survey Committee of the 61st General Assembly was created by Senate Joint Resolution for the purpose of studying current highway require- ments, including finances and administration, in relation to needed or proposed legislation. Professor C. C. Wiley v/as appointed special engineer to this committee by Acting Governor Stelle and served from March 29 to June 15, inclusive, in 1939. His duties v/ere to study the general problems, analyze proposed legislation, and act as tech- nical adviser to the committee. His reports were made to the com- mittee and were Included in the conunittee' s report to the two houses. Much of the work related to a mode of financing a system of super- highways for Chicago but Included a scheme of local roads downstate. Other important bills related to changes in motor license fees and the motor fuel tax. All of these adversely affected the state road program and the committee's work resulted in their elimination. Professor Wiley* s work aided materially in keeping the Illinois high- way program on a sound basis. ,i|r ;; Si:. -22- Caribbean Bases . — During the summer of 19^1 Professor J. J. Doland served as principal engineer for the Trinidad District of the U. S. Engineers Department in charge of the engineering division. The project involved the construction of air bases and fortifications at Trinidad, St. Lucia, and Antiqua, in the British West Indies, and British (Juiana in South America. The work included site inspection formulation of construction policy, and approval of plans and specifications proposed by the Caribbean Architect Engi- neer. This was a substantial contribution to the war effort by a member of this staff. National Resources Planning Board . — Professor James J. Doland has been rendering valuable service to the National Resources Planning Board since 193^» ^^ July 193^ ^e was appointed Associate Consultant and prepared water plans for nearly all river basins tributary to the Mississippi River from its source to Cairo, Illinois. These reports v/ere published in abstract form by the Planning Board. In 1937, he revised the 193^ plans with suggestions from Drainage Basin Committees composed of Regional, State and Federal representa- tives. These were published in 1937* ^^^ 193^-, ^e continued the Basin Committee work which involved conducting meetings and prepara- tory reports of the meetings held. Emphasis xras on evaluation of projects and their relationship to a satisfactory basin plan. In 1939» he continued the Basin Committee v/ork and in the summer was called to Washington for staff duty in charge of the evaluation of projects contained in the Six-Year Federal Construction Program from 19^0 to 19^6, In 19^1-0, ho was appointed consultant for the entire Ohio Drainage Basins. He conducted basin committee meetings and continued the development of integrated plans for both the Ohio and Mississippi drainage basins. In 19^+1, he continued the basin committee work and was appointed vice-chairman of the Evaluation Sub- Committee of the Water Resources Committee. This committee was char.ged with recommending action to the Bureau of the Budget for all water projects. Such recommendation is necessary before construction funds are allotted. In 19^2, he prepared completely revised Basin plans for the Upper Ohio, Kanawha, and Miami- Scioto-Hocking River drainage. The Evaluation Sub-Committee was changed to the^ Project Review Committee of the National Resources Planning Board and is charged with the evaluation of all Federal Projects. Professor Doland was also appointed Chairman of the Cooperative Investigation Committee which is charged with the development of techniques and procedures for coordinating the investigation work of the several Federal agencies which may be working in the sa.me region. The pur- poses are to avoid duplication of effort, to prevent inconsistent findings, and to reconcile conflicts which would be adverse to the best interests of the region. By serving the National Resources Planning Committee in these capacities. Professor Doland is render- ing valuable service to the Federal Government and is at the same time gaining experience which reflects favorably on his teaching. ;:a:;:;i ^23- River Basin Reports * — In 1935* ^^ the request of the Illinois Emergency Relief Uornnission, a study was undertaken by the Civil Engineering Department to determine possibilities for public construction projects In the Basin of the Birj^ Muddy River In southern Illinois on which relief labor could be used. The department re- quested and received the cooperation of other University departments and the three State Surveys located on the campus. At that time, a large percentage of the population of this area was on relief. The men were r-.ostly coal miners who were out of employment because of the declining demand for coal from the region. They were, there- fore, accustomed to manual labor. For many years, Professor G-. W, Pickels had been studying the possibilities in this area for the creation of reservoirs by the construction of dams. Since earth r'^ams involve a large amount of labor and a relatively small material cost, they are ideal work- relief projects. His studies shov/ed that there were desirable dan and reservoir sites located near the center of the relief load and it seemed quite possible that further study on the part of the Relief Commission or other agencies might show that the construction of some of these dams would justify the cost involved. After considerable discussion by Federal Agencies, the construction of a dam on Crab Orchard Creek by the Resettlement Administration v/as approved. This was completed at a cost of about 13,000,000 and the first water flowed over the spillway on December 27, 19h-1 about exactly 7 years after the first visit was made to the site by representatives of the group m.aking the report. Crab Orchard Reservoir is 9 iniles long, has a storage capacity of about 3^ billion gallons and is the largest lake in Illinois. Two other dams were constructed en tributaries of Crab Orchard Creek and form reservoirs with a combined capacity of about 20 billion gallons. The government- owned area around these projects adjoin the Illlni and Shawnee National Forests. The U. S. Forest Service has planted thousands of evergreen trees on this area which will add greatly to its attractive- ness. The recreational possibilities of the lake were discovered immediately as evidenced by the cars, approaching 15,000 in number, which \jere parked around the lake on some Sundays in the summer of 19^1. The lake is located in a region which has little ground water and is often short of water for domestic and other purposes. Water is frequently supplied to some communities in tank cars. Practically no dependable water supply has been available for industrial use. In the summer of 19^1, the water shortage was especially serious in Carbondale which is about three miles below Crab Orchard dam. To re- lieve this situation a water main was run from the town to the reservoir. The most important development vjhlch has grown out of the Crab Orchard project is the U. S. Army Ordnance Plant which occupies 35 square miles around the east end of the lake. This land is of little value for farming purposes. The location is desirable -2i+- because of the large labor supply available portation facilities. However, the location site was made possible by the v;ater supply i in turn developed out of the report which ha 50 million dollars was spent in the construe the monthly payroll for operation runs into All of this has been of great aasistance to in such desperate financial condition.

W. Pickels, H, E, Babbitt, and W, C. Huntington. The latter served as chairman. A hundred-page mimeographed report supplemented with many maps was issued. About 200 copies v/ere distributed but there has been a demand for many more because of its great significance. In 1937, the Illinois State Planning Board requested the University and the three State Surveys to make a study of the Basin of the Kaskaskia River. This study was similar to the Big Muddy study but more comprehensive. The civil engineering staff members who participated were Professors G-, W. Pic]7.els, J. J. Doland, and W, C. Huntington. The latter served as chairman. A three-hundred page mimeographed report was issued. About 1,000 copies were dis- tributed. So far, no practical results ha.ve come from this report but it may, at any time, prove to be quite pignificant. National Research Council . — Prof ops or N. M. Newaark is serving as Consultant to the Committee on Passive Protection Against Bombing of the National Research Council and the National Defense Research Committee of the Office of Scientific Research and Develoj^- ment. His work is concerned with various toi^ics relating to the defense and war effort. Most of the work is of a confidential nature and cannot be described here. Generally it relates to the development and testing of methods of structural design, particularly in reinforced concrete to improve the resistance to bombing. Pro- fessor H. E, Babbitt is a member of the Advisory Committee on Sani- tary Engineering of the National Research Council, Navy and Maritime Commission . — During 1935 -^nd 1936, Pro- fessor Nevjmark was consult^.nt to the Bureau of Yards anc". Docks of the U, S. Navy on special features of the structural design of a large floating dry dock. Recently he has been consultant to a builder of concrete cargo ships for the U, S. Maritime Commission. His work has been concerned v/ith special features of the structural design of the hulls. -25- Clvll Works Administration . — At the close of the year 1933 and the beginning of 193^, Professor W. C, Huntington was appointed by G-overnor Horner to talte direct charge of forming an engineering organization to approve plans, purchase materials, and equipment, and supervise construction for projects on which men on relief In the State of Illinois could be employed through the Civil Works Administration. Beginning as the only member of such a staff, on November 19, 1933> ^^ ^^^ necessary for him to develop a state-wide organization with such speed that one hundred thousand men could be placed on the payrolls In two weeks- from the tlm.e he was notified of his appointment and another one hundred thousand could be added by the end of the following two weeks. The number employed reach a peak of 226,000 on January ig, 193^, "two r^onths after Professor Huntington was appointed. At that time, the engineering staff numbered 1200. The total expenditures for labor up to April I5, 193^ were 53 million dollars and for materials 6 million dollars, making a total of 59 million dollars, not Including the several million dollars spent by the public agencies for v;hom the work was done. By April 5j 193^ the number employed was reduced to 11^,000 and from then on the program was brought to a close as rapidly as possible. The program was Intended as a stop-gap to take care of the critical unemployment situation durinr; the period while the slower-moving Public Works Administration TPwA} was retting underway. The Civil Works Administration organization in Illinois performed in an effective and creditable manner. By pajrticlpntin;];, as it did, the University rendered a valuable service to the State anr! Federal G-overnment, Caribbean Base . — The remote location of rock for concrete aggregate required for the U. S, Air Base at Hyde Park, British Suiana, South America, created a tir.e hazard in the completion of runways. The availability of a beach sand at the air base site suggested the possibility of the use of this material in place of rock for the concrete used in taxi ways and parking strips and possibly for the runways themselves. Data were needed on the abrasive resistence and ultimate strength of the concrete produced by the use of the sand with Portland cement. Professor E. E. Bauer devised a unique type of test to determine abrasive resistance, A large sample of the sand was shipped to the University of Illinois laboratory and as a result of the test the material was used for parking strips and taxlways. This resulted in the saving of valuable time and consider- able cost to the government. -26- d. Conferences and Short Courses The civil engineering staff holds annual conferences and short courses to assist engineers and others in keeping up to date with developments in their fields. The Annual Conference on Highway Engineering started in 191^ as a Short Course in Highway Engineering, These conferences are directed by Professor C, C. Wiley. During the period 193^ to 19^2, two other conferences and two short courses have been inaugu- rated. The Annual Surveying Conference held in cooperation with the Illinois Society of Engineers was started in 1932» These conferences are directed by Professor W. H, Rayner. A Traffic Engineering Con- ference was started in 19^1 with the intention that it be biennial. It was directed by Professor Wiley. This conference is sponsored Jointly by the Departr.ient of Civil Engineering and the Illinois Division of Highways. The first Short Course for Water Treatment Plant Operators was held in 19^0, The State Department of Public Health cooperates in this conference. These courses are directed by Professor H, E. Babbitt. The first Short Course for Sewage Treatment Works Operators vms held in 1939« I'he State Department of Public Health cooperates in this course also. These courses are directed by Professor Babbitt. The increase in the number of meetings of this type since 193^ show the progressive spirit which prevails in the staff. Such meetings are of considerable value to the engineers of the state and add to the University's prestige in the state. y^\< •ad ~i:::iiit -27- k. COMPARISON OF PRODUCTIVITY AND PROFESSIONAL ACTIVITIES a. Engineering" E^cperlment Station Publications for the Nine-Year Periods 193^19^2 and 1925-1933 An Important index of research activity in the department is the number of publications of the Engineering Experiment Station. These are reports on major pieces of research which usually Involve large expenditures of time and money. Most of the more expensive projects are carried on by cooperative agreements with agencies which pay the direct cost of the investigations. These are commonly public agencies or technical societies such as: Civil Public Roads Administration The American Society of/ Engineers Federal Works Agency San Francisco-Oakland Bay Bridge Bureau of Ships U. S. Navy Engineering Foundation The Division of Highways of Illinois Association of American Railroads The American Welding Society Portland Cement Association The total amount received from outside sources for projects of the Engineering Experiment Station was $1^1-9,000 for the nine-year period 193^ to 19i+2 and |g2,000 for the nine-year period 1925 to 1933. It is seen that those funds have nearly doubled in the last nine- year period. This is a very definite measure of the amount of organized research being carried on in the civil engineering depart- ment. Also, an examination of the publications resulting from this research will show conclusively that the quality has certainly been maintained. Actually there has been an improvement in this respect as would naturally be expected from the accumulated experience of those who are doing the work. One of the best measures of the quality of this research is the continuous support given by various agencies. All of this research is basic in character and in no case is money accepted for research which would promote the sale of any product. Any commercial aspect is carefully avoided. Two me N. M.

Without doubt, the Engineering Experiment Station organization contributes greatly to this. This phase of the organization is a very desirable one because the Station is not a separate entity but is open, without formal action, to all members of the staff whp are interested in research. The active program of research carried on in close contact with instruction Improves the quality of both. Through the Research Graduate Assistantshlps, the research program in the Station has a definite training value which might be considered as comparable to the value of the results of the research. This effect is evidenced by the outstanding^, records in research made by many who h,nve served as such assistants. The forward trend of the department in research is very definitely indicated by a comparison of the number of publications during the two periods under consideration, as listed in the follow- ing pages. For the nine-year period, 1934 to 19^-2, there were 24 Bulletins and 3 Circulars, makin-^ a total of 27 publications, while during the nine-year period, 1925 to* 1933, there were 12 Bulletins e^data are for present productivity of the staff and 1 Circular, maJcing a total of 13, Th( members of the staff and indicate that th< has doubled during the last nine-year period. If the publications of all of the members of the staff for' both periods are included the total from the nerlod 1934 to Bulletin and from the period 1925 1942 would be increased by one to 1933 "by "two Bulletins. This trend of the department in research is still further emphasized by comparison with the preceding nine-year period 1916 to 1924 during which there were only three Bulletins and three Circulars published. Two of the Bulletins and the two Circulars were by Professor Wilson v/hile one was by Professor Babbitt, who was not then a member of this department. The number of Experiment Station publications by members of this department may be summarized as follows: •• All Members Prcfiont Members 1916 to 1924 6 6 1925 to 1933 15 13 1934 to 1942 28 27 These data indicate quite conclusively that the increase in research activity in the department, as indicated by these publications, is very marked but an examination of the publications will show that this increase is even m.ore marked beca.use there has been a strong trend toward more extensive, more costly, and more* significant re- search as the general program of research develops. v'>';'-.">vv.': da i -29- Comparlson of Publications by The Engineering: Experiment Station page - 3 The publications of the Engineering Experiment Station by members of the civil engineering staff have had a pronounced effect on engineering practice. They have resulted In new design procedures and changes In old procedures. They form the basis for many design specifications and give basic data on which designs are based. The Proceedings of the Annual Highway Conference, which are published as Circulars, are not Included in this discussion. There have been seven of these all since 193^» These are not in- cluded in the fo2*Ggoing tabulations.

These books cover nearly all phases including matorials, surveying, highways, drainage, bridges, and buildings, and indi program in the department. All of these b ceived and most of them have won positions the leaders, in their respective fields. engineering staff have oks. Probably no other ntry has written as of civil engineering water supply, sewage, cate a well balanced ooks have been well re- or leaders, or among Three factors enter into the appraisal of one's book writing activity. The first factor is, of course, that he must write; the second, that the book be of high quality; and the third that it be kept abreast the times by revision. It is to be expected that, after one writes a book, he will devote his energies' available for such work to keeping the book up-to-date if the book is successful. During the nine-year period from 1925 to 1933* six books were written by present members of the staff and three books were revised. During the following nine-year period from 193^ to 19^2, three books were written and nine were revised. This is in accordance v/ith the natural trend mentioned above. These data do not include books for which members of the staff were junior authors with members of the staffs of other institutions or books to which they contributed chapters or sections. There have been several such contributions during both periods. The data presented show that the department has been very active in book v;riting and that this activity has continued through both periods in question. That the staff will continue its productivity in book v/riting beyong the year 19^2 is evidenced by the fact that the manuscript for a book on "Earth and Masonry Structures" by W. C. Huntington is far advanced and a contract for publication has been entered into with John Wiley and Sons; a large amount of work has been done by Professor J, J, Doland on a book on "Water Power Engineering" and a contract for publication has been signed v/ith John Wiley and Sons. An agreement has been reached betvreen Professor T. C. Shedd and John Wiley and Sons for a book on "Bridge Design", the manuscript for which is well under way; and the manuscript for a book on "Soil Testing" by Professor E, E, Bauer is nearly complete although no arrangenent has yet been made for publication.

Airtlcleg. and Rer)orts for the Nine-Year Periods 1934-1942 and 1925-1933 The followint; pages list the papers, articles, and re- ports by present members of the staff for the tv/o periods beinr; considered. All of the documents in these classes as listed by members of the staff in tho annual Record of G-eneral Activities, compiled for the Dean, are included for comparative purposes al- though it must be realized that some of the papers are the result of many months or even years of study while others required relatively little effort to prepare. This comment applies to^ both periods. However, the complete list as ^^iven serves as one means of comparison of the activities of members of the staff. The three associates in the department are not included in this list although they have done some writing. Two of these men are studying toward the doctor's degree and "have devoted all of their available time to graduate study and v/ork on their doctor's theses. Certainly one, and possibly both, of these theses will develop into a Bulletin of the Engineering Experiment Station, An examination of the following pages will show that members of the civil engineering staff have been active in writing papers, articles, 'and reports covering practically all phases of civil engineering. Also, it will be seen that this activity during the last nine-year period is a'oout double that during the preceding nine-year period. This increase would naturally be ex- pected as the staff members develop and merely serves to indicate that development is taking place. Certainly tliere is no indica- tion of decrease in productivity. The actual number of articles in each period is of no great significance.

Committees of Technical Societies for the Nine-Year Periods 193^19^2 and 1925-1933 Evidence of the trend of the Civil Engineering Department for the years 193^ to 19^2 can be gained by comparing the member- ship and activities of members of the staff in the affairs of national and state technical societies for that nine-year period with corresponding data for the preceding nine-year period. On the following pages are given tabulations of society memberships in 1933 ^"^^ 19^+2 followed by lists of the committees of these societies on which members of the staff have served during the nine-year periods 193!^- to 19^^-2. and 1925 to 1933* No committee records are Included for Messrs. Evans, 3rielraaler, and Clark, who are associates. They have served on few committees largely because of the time devoted to graduate study. The primary source of information from v/hich these data have been compiled is "The Record of General Activities", a form each staff member fills out each year for the records of the Dean of Engineering. On this blanic, lie expects each staff member to give complete information concerning all of the technical committees on which, he is serving for the current year. No effort is made to distinguish betv/een the importance of these committees. Since the present report is for comparative purposes, all of the committees listed by each staff member during each nine-year period are given so the records for the two periods will be com- piled on the same basis. They include committees and sub-committees. If a staff member has been chairman of the committee at any time during the nine-year period, he is listed as being chairman although he may or may not have been chairman for the entire nine- year period. Society offices held are included. Other sources of information are the "Annual Reports" of the Department which do not vary much, in this respect, from the Record of G-eneral Activities because the latter is used in preparing the formtr. Each member of the staff has examined the data which refer to him and has stated that they are correct. In examining this material, it should be kept in mind that some of the societies have increased their committee activity during recent years and that this would naturally be reflected in the number of staff members serving on committees. However, it is certain that this factor could only partially offset the large in- crease in committee activity by members of the staff. ..'"1 -49- Comparison of Activities on Coranlttees of Technical Societies page - 2 Servinr, on the comnittees of technical societies is con- sidered to be an important factor in the quality of the instruction, writing and research done by members of the_ staff. It keeps them in touch with the develooments in their various fields and en- courar;es participation in such developments. It promotes acquain- tance witii other ea^^ineers and f^ives them information concerning the work being done by the department. Comments and criticisms of committee members on reports submitted by staff members contribute to the value of reoorts on research projects or other procedures followed in any study. The appointment of a staff member to a com- mittee is a recognition by his associates that he is qualified to contribute to the work of the committee and is, therefore,* a recognition of the work being carried on by the d.epartment. In order to serve on committees, ^ it has been for staff members to attend meetings of the societies, dance at such meetings has been noteworthy. This has large expenditures for traveling expenses, which v;ith have been paid by the staff member because the Univers pR,y such expenses, even in cases where they present pa societies d.o not often pay such expenses. Since most held at a considerable distance from Urbana, the cost especially large for m.srnbers of this staff. necessary Their atten- involved rare exception, Ity does hot pers, and the meetings are of travel is An examination of the data presented will show quite con- clusively that the members of the staff of this department are active in nearly every phase of civil engineerlnj; work and that their activity has been Increasing through the years. page it By consulting the membership ta,bulatlon on the following will be seen that eveiy member of the staff is a member of the American Society of Civil Engineers, the leading national society in his general field. Also it will be seen that staff mem- bers belong to many other national societies representing his special interests and to the state society. The total number of ^ technical societies to which staff members belong is 20, the total number of memberships is 76, and, the average per member is 4,5, This does not include Sigma Xi. Nearly all of the members of the staff belong to these societies. The number of offices and committee memberships held by members of the staff for the two periods being compared is: 1925 to 1933 193^ to 1942 All Members 98 196 Present Members 88 187 I At cfS^ -50- sdTilsaaquiaiAi i^aoj, to tnoj rH r^zt LPsCMvo r^mvo j-.d- t^irso^ 0^ sa89UTSu3 OTJJ^^I JO a^naiasui OJ rH JO jCq.afoos 'uiV cu .H •X -N JO •u,ssv iTBici x^uofSsH OJ H •Su3 -[^uoxssejoJci JO 'oos l^uofaHM OJ cu OJ • f^ •u,ssv OJ rH •U,S9V sx«io/i aS^MSS 385.-60.8 lHa:;uao cu rH •2u3 •q.ona^S =? aSpT^H •u,^ssv iBU0Tq.BUj:ac^ui cu r^ cu uoxun i-BOTs/lqdoe-o 'uiV t\j f^ C\J 90U8T0S JO "Apv J.OJ 'oossv *'W cu f^ OJ Uissv SuxpiTng p-eou 'm ^ '^ OJ s:;s-;SoT:oiu:oaj,j ^ rH " u I s SY i rH JO 'OOS SfOUTIIIj O rH •u,ssv '3-y[J.o^x iJ9Q.^Ai 'UIV f^ i^ <^i f><-N •Sua TO 'OOS UJ.9%S3^{\ r^N H C\J 8^nq.Tq.sui 8q.aaouoo 'm\ r^cu r-^CKi ^'^c^J cvii r-- 1 SuT^^syj, aoj 'oos 'W t i 'u,ssv 'Sua y^-CMXT^H *W r^ cu i^ r^^ ^ uo-fq.T?onp3 •Sua JO 'moacj joj 'oog KNCU t^rH OJ r^ r^KM^KM^oj r^ rH "Sua ITATD JO 'oos 'inv h^r^oj OJ t<>r^K\oj r^^cu KNro>K\r^KNKM^ iliST ^ouTS jj^as pauTor XX XX Total Memberships E Q 1 JH.E.
