SEA: "17 -4A+ CINCINNATI: Printed for the author by Robert Clarke & Co. 1893. Copyright, 1893, by James M. Searles. PREFACE. Should the Life and Times be read by any of my civil engineering acquaintances, I trust that they may wish, and hope for me, pleasant and profitable success in determining, for my chief (Mr. Sylvanus Miller), a good location ol the Ferro Carril del Norte, in Guatemala — for which country I propose embarking before this little book shall be given to the public. The true theory of the Mississippi river is Mr. Charles Ellet's ; and my sole purpose in making such liberal extracts from his great work, is to call the attention of the United States Congress to it in its entirety, that they may be convinced that the Mississippi river problem can be best, most economically, and permanently solved, by outlets, levees, and res- ervoirs.

LIFE AND TIMES OF A CIVIL ENGINEER I propose, in writing of the life and times of a civil engineer, not to attempt instruction in a science which is cosmical in its character and extent, and, therefore, I confess, beyond my ability ; and totally incomprehensible, I verily believe, to the large majority of those who add to their names the two letters C. E.; but, to speak of my experiences as they may occur to me, and thereby, perhaps, be instru- mental in guiding my professional brethren amid the rocks and shoals which are to be met in the current life of real practical engineer- ing. The profession comprehends so much that hesitancy should govern many who pro- pose to adopt it. The precaution is stated, because, not alone that mathematical educa- tion and cultivation are necessary, but that the ability to practically effect or illustrate the great truths of engineering is essential. It may seem a strange and curious circum- stance that, at this time, it should be declared that a science, founded on mathematics, and 4 Life and Times of a Civil Engineer. practically demonstrated by the greatest and grandest physical achievements of all ages, should be, at this epoch, very frequently di- rected — so far as money and adventitious cir- cumstances can and do, direct — by those who have only entered on the threshold of the en- tered apprentice degree. But so it is. He who is least acquainted with the fundamental principles of geometry, to say nothing of nat- ural philosophy, therefore totally uninformed or incapable of practically demonstrating the great truths of those sciences, is the one se- lected, by the very circumstances as indicated, to govern a staff to whose judgment and ef- forts, if the plan and conduct of the battle were left, success would always respond. To give more pertinency to the thought intended to be expressed, the grand results are not to be denied, but the credit for their accomplish- ment is generally appropriated by those who have been negative factors in the working-out process. Occasion will be taken, in the course ol these pages, to particularize some of the re- sults of the circumstances alluded to ; and such, it may be said, will continue as results so long as arrogance can blind the eyes of capital. To forestall abrupt criticism, it should be Life and Times of a Civil Engineer. 5 mentioned that the immediate foregoing state- ment is made to set forth and illustrate the fact that the majority of practical civil engi- neers are modest in their pretensions. Having done with prefatory remarks, I will begin the Life and Times by. announcing that I was born, not of humble, but illustrious par- entage, in that it was honest and always spoke the truth. My schooling as a civil engineer was begun at " Old Brimstone Castle," in the town of Alexandria, Virginia, situated on the right bank of the Potomac river, about seven miles southward Washington City. Within the walls of that old institute, and, I may add, venerable, inasmuch as it was pre- sided over and conducted by Benjamin Hallo- well — than whom none was more able to teach the truths of a great and noble philosophy — I was taught the mathematics which have served me as an engineer. The associations of the times and place are to me of the most pleasant recollections of early days, and should these pages be read by any of the classes of 1 853—54, I trust they too may be gratefully reminiscent of the times when all was indeed " quiet along the Po- tomac." 6 Life and Times of a Civil Engineer. I can recall just now but few of the names of those who composed the classes of thirty odd years ago. First in order of recollection, because of our close and reciprocal friendship, is Bailey Peyton, Jr. He was the eldest son of the Hon. Bailey Peyton, of Tennessee, who represented that state in congress, in times when the office sought the man, and public of- fice was regarded as a public trust, and the records of those days bear testimony to his ability and patriotism. The son gave every evidence of that precocity which sometimes distinguishes uncommon genius. He was cut off, in budding manhood, at the battle of Mill Springs, sharing the lamentable fate of the gallant Zolicoffer. There were, also, Edelin, of Washington City ; Buchanan, of Maryland ; Martin, of New York, and others, bright and noble fellows, all of whom, I trust, have journeyed pleasantly up the hill of life, and are still achieving, still pursuing, those things which will make them happy here and happier hereafter. Before completing the entire curriculum of the Hallowell Institute, I secured, through a recommendatory letter of the then Secretary of War, a position as aid on the United States Cost Survey. This work was conducted under the super- Life and Times of a Civil Engineer. 7 intendency of Alexander Dallas Bache, and certainly no one could have been more em- inently fitted for so high and responsible a po- sition; He was not only a mathematician, capable of comprehending and applying all those geodetic principles which were demanded by the survey, and as contemplated by the act of congress authorizing the work, but he added to this accomplishment an administrative ability which has never been equaled, if, indeed, ap- proached, by any of his successors. It was the writer's good fortune to be personally as- sociated with Prof. Bache, during two summer seasons, in the State of Maine, while the work of primary triangulation was being carried on in that district. The superintendent's princi- pal assistants were Geo. W. Dean and Hilgard. My duties consisted in recording and com- puting the trigonometrical observations as made by Dean. Hilgard, who was engaged in the determination of the latitude and longi- tude of the trigonometrical points, was likewise assisted by my tent mate, Robert J. Brecken- ridge. I had also to make, in addition to the duties enumerated, meteorological observations three times per day. It was during this summer work that the su- 8 Life and Times of a Civil Engineer. perintendent prepared his annual reports, being assisted by a large clerical force, of whom I well remember Hoe, Cooper, Hugh McHenry, and Hayden, and my old friend Col. McDon- ald, the "Atificer." He would never consent to be called the carpenter. During my probationary experience in this particular class of work, the party occupied Mounts Sebattis, Blue, and Ragged as observ- ing points. The heliotropers — or signal men — were located at various other stations, such as Mounts Washington, Pleasant, Kearsage, Har- ris, Cape Small, Isle au Haut, Mt. Desert, and Katahdin. It was on our first visit to the State of Maine that I was sent, in company with Hayden, ahead of the party, to look out a convenient camping-ground about Mt. Blue. Arriving at the little village of Phillips, on Sandy river— every thing in the shape of a stream in this country is dignified with the name of river — the Sandy was about twenty feet wide between top banks — we put up at the hotel of the place, and found supper ready some time before sun-down. The hour of the evening meal was an un- usual one to us, but we were glad of its early coming, as we had appetites that had been hugely built up by a long and jolting stage- Life and Times of a Civil Engineer. 9 coach travel ; so that it did not require the ringing of a second bell to persuade us to the eating-room. Being seated, I was surprised to find the table almost covered with sweetmeats — jellies, preserves, cakes, and pies. There was a total absence of meat. This display was not, however, disconcerting ; but when the landlady asked me if I would take "long or short sweetening" in my coffee, I was sadly confused. I made out, for a while, that I had not heard her ; but realizing, in a moment, that I had, ordinarily, a very sweet tooth, and that I had better take all the sweetening that was offered, I answered that I would " take it long. I have a very long remembrance of that cof- fee — it was " molasses boiled in." My stomach had been aristocratically trained up to the en- joyment of dripped coffee, sweetened to my taste ; so, when breakfast came about, I re- quested the hostess to give it to me " short." We w r ere put to no trouble in making ac- quaintances, as the natives surrounded and plied us with all sorts of questions. A negro boy, John, whom w r e had brought along as a camp waiter, seemed to be an object of ex- ceeding curiosity to them. He w r as as black as charcoal ; and from the w r onder expressed by the people — big and little — as they looked io Life and Times of a Civil Engineer. him all over, we judged that they had never before seen a human being of his complexion. The boy seemed bewildered by the attention that was paid him. While engaged in answering inquiries as to where we lived — -what kind of a country was "down South" — what the coast survey was doing away back among the mountains — how they worked the poor colored people down in Louisiana and Mississippi- — did they really whip them to make them work ? — did you ever see any alligators ? (ku-klux hadn't been born up to that time, else we might have been drawn into a political talk) — we noticed a game of grace hoops that was being played by quite a number of pretty girls in the grassy front yard of a place across the street. The girls had formed a ring, and each one, in turn, would throw the hoop at one or another, and if suc- cessful in encircling the head of one of the party, she had to submit to a kissing by the thrower. On remarking that it was a mighty nice game, and that a boy, in such a game, would never grow tired of it, one of our new ac- quaintances, a Mr. Prebble, at once insisted on our going over and taking a hand. Of course we blushingly demurred to such a proposition, as the girls might object, and as we had had Life and Times of a Civil Engineer. 1 1 no introduction, etc. We were, not excused on any such formal or conventional grounds, and Prebble conducted us over to the charming cir- cle, saying, "Now take your places with me, and throw the hoop to ketch a gal, and, when you ketch one, just run and get your pay." Well, such a time as we had. Suffice it, we had a good play, and the very best of pay. The primary triangulation was made with a theodolite of large magnifying power, so pow- erful, indeed, that a signal pole of six inches diameter could be distinctly seen at a distance of from sixty to seventy-five miles — and at even greater distances when atmospherical condi- tions were peculiarly favorable. The time of occupancy of a station varied from one to three months, according to the state of the weather. Owing to the high alti- tude, it was frequently the case that these poifits were enveloped by dense clouds, pre- vailing for days, and even weeks. The angles were repeated twenty or thirty times in three different positions of the instru- ment. This was done in order to eliminate, as much as possible, any errors of graduation. The azimuth circle was provided with three micrometers, by which the readings were very closely made, thus precluding any probability of an error in measurement exceeding a small 1 2 Life and Times of a Civil Engineer. fractional part of a second, after determining the mean of the repeated observations. As an evidence of the exactness of the work, six triangles were tested, and the greatest error was found to be but six-tenths of a second. This accuracy is arrived at by extreme care in the measurement of the base ; the selection of well-conditioned triangles (i. e., may have such sides and angles that a small error in any of the measured quantities will cause the least possible error in the quantities calculated from them), down to the determination of personal error and spherical excess. The position of each trigonometrical point, with reference to the north star (i. e., its azimuth) was observed, as also its latitude and longitude. The first superintendent of the Coast Survey was Hassler, a Swedish scientist. The great theodolite was constructed after his designs, and under his supervision. It is reported of him, that on the occasion of a conversation between himself and President Jackson, with reference to a suspension of the work of the survey, he became very much ex- asperated by " Old Hickory's " remarking that the government could do without the survey and its superintendent as easily and as readily as it could change its chief executive officer. Life and Times of a Civil Engineer. 1 3 " I think not," Hassler replied, " because the people can, at any time, make a President, but it takes God Almighty to make a Hassler." The effrontery of the assertion might, in a measure, be palliated by the real scientific abil- ity of the old man, and we should not be too hasty in condemning the propriety of his lan- guage, when, it is remembered, that there have been so many manifestations of impudent as- surance by numerous j^z/;^ men, styling them- selves Civil Engineers. On the approach of the winter the party was sent South to engage in the determination of difference of longitude between points in sev- eral states. Our corps occupied, successively, during two seasons, Montgomery, Ala., Wil- mington, N. C, Columbia, S. C, and Macon, Ga. At these and other places, astronomical observatories were hastily erected and con- nected by telegraph. The electric connection was made with a clock and chronographic ma- chine that recorded the observations. The same catalogue of stars being observed on the same night, by the observers at two stations, and the right ascensions repeatedly and accurately recorded, the differences of longitude were found to a nicety. The ob- server having a break-circuit key whereby to record his observations of passage of the star 1 4 Life and Times of a Civil Engineer. across the wires of his transit, could measure a fraction of a second on the chronograph. It was during my connection with the trig- onometrical party in Maine, and when stationed at Mt. Ragged, near the Penobscot Bay; that I met with Professor Joseph Henry. Apart from my appreciation of the man of science, to whose profundity of knowledge a universal tes- timony has been accorded, an observance of his social characteristics was confirmation, to my mind, that modest and natural simplicity is linked with, and inseparable from, true great- ness. In this, as in many other points of char- acter, he had his counterparts in Professor Bache, and that other grand old man and pa- triarch, Benjamin Hallowell. It would be edi- fying and instructive, to an appreciative public, to read the autobiography of the Quaker school-teacher. In the course of my movings around, I was sent to Old Cambridge, near Boston, as an aid to Dr. B. A. Gould, who had charge of the Coast Survey Astronomical Observatory at that place. The doctor was a gentleman of high scien- tific attainments, as the records o( the Coast Survey Office abundantly testify, and, consider- ing his ability and activity in the astronimical world, it is a matter of surprise that his fame Life and Times of a Civil Engineer. 1 5 has not been extensively published. While with this gentleman, I was also employed in the calculation of moon culminations, under the direction of Prof. Benjamin Pierce, the great mathematician of Harvard College. It is indulging in no extravagance in denom- inating him as great, when the learned men of the Athens of America pronounced him peer- less in the realm of his special science. He was a frequent visitor at the Observatory, and I remember that, on the occasion of one of his calls, he had a very earnest and excited conversation with Dr. G. On the day follow- ing, while talking with the doctor, I spoke ol the professor, and expressed some curiosity to know the reason of their animated colloquy of the past night. The doctor was rather re- luctant to confess the unamiability of his dis- tinguished friend, and disposed to extenuate his exhibition of bad temper because of indi- gestion or some other physical ailment, but he finally communicated a piece of intelligence that impressed me with the belief that the Harvard professor had but little respect for in- ternational courtesies. It seems that he had, about that time, con- cluded and published his ad-captandum of math- ematics — the Theory of Probabilities — and that he had received a letter from Prof. Airy, the 1 6 Life and Times of a Civil Enginee7 r . Astronomer Royal of Great Britain, in criti- cism of the theory. This was not to be put up with ; and, in a fit of anger, he answered the British officer in about this style : " I don't know that I am surprised at your not compre- hending my theory, but I should be if the dull- est sophomore in college were in your mental condition ; and it is my opinion that the title of Royal Jackass of Great Britain would better designate you than the one your government has bestowed on you." The letter, though dropped in the post-office, was taken out by the good doctor, and never met the eye of the trans-atlantic star-gazer. As a little spark some- times kindleth a great conflagration, so, per- haps, if the mail had been faster than the doc- tor, the Britisher might have submitted the letter to his government as an international discourtesy, and brought about a war, with all its dire and fearful consequences. Why not ? Many a one has been fought because of a the- ory ; and as the Harvard man's theory was greater, and of more possibilities and proba- bilities than most of the political theories of the day, we are at liberty to congratulate ourselves on escaping a conflict with the great naval power of the world, Before dismissing the subject of the Coast Survey, it should be said that it is the best Life and Times of a Civil Engineer. 1 7 schooling in the world, perhaps, for a young man proposing to enter the Civil Engineering profession. It affords him an opportunity for employment and application of the higher branches of mathematics, in the acquisition of the knowledge of which he may have spent years of laborious study ; it gives him a famil- iarity with the construction and handling of the finest and most delicate instruments that are used in the geodetic works of the civilized na- tions of the earth ; and, as its methods and ex- actness should have their influence in deter- mining his work, he will thus lay a foundation for fidelity and precision of observation and calculation in any of the branches of engineer- ing and surveying work to the study and prac- tice of which he may be called. It is not here contended that a probationary experience on this national work is a necessary part of the education of a Civil Engineer, but that an experimental acquaintance with its va- rious departments will prove a material help, as a mathematical preparation, to one who shall afterward engage in the practical solution of the many and wonderfully complex prob- lems which come up with the necessities pf the time and age, and demand, for their solution, an aptitude to select from the vast storehouse of geometry and its concomitant sciences, and 1 8 Life and Times of a Civil Engineer. so apply as that the demands of such necessi- ties will be fruitfully realized. ^j> 4fe 4t£ 4& $& •$& Severing my connection with the Coast Sur- vey service, I at once entered on railroad work, in the double capacity of chainman and rod- man, on what was then known as the Missis- sippi Central — now the Illinois Central. The assistant in charge of the party to which I was assigned was George R. Wilson, an untiring and indefatigable worker, quick in judgment and rapid in calculation, and filling the bill, in every particular, as a field Engineer. I remained on the line but a month or six weeks. I have always possessed a very large amount of endurance, but as I had to perform double duty during a summer season of ex- traordinary heat, attended with a drought, which is always a matter of anxious concern to a surveying party — as many a one can testify who has had to satisfy a thirsty craving at a mud-hole or a horse-track — and had also to pay for my own subsistence — and this, too, to hunt up, after twelve hours' work, by walking as many miles as would tire a mule — I concluded not to stand on any particular order of going by sending due notice to headquarters of my intention, and notifying it that, on some certain day, it would be privileged to. fill my responsi- Life and Times of a Civil Engineer. 1 9 ble position by the appointment of some party who might wish for hard work and very small pay ; but I went, and went so fast that, on a hot August day, I tramped over forty-eight miles, carrying, one-third of the way, a thirty- pound transit instrument. This is on record as fair pedestrianism for a non-professional. My next service was on the Vicksburg, Shreveport and Texas road. Col. Bonner was Chief Engineer. The assistant to whom I was assigned as rodman was Darrow. Like my former chief, Wilson, he was an industrious worker, but without his capacity to recognize those economic principles which should govern and direct manual labor in surveying, as in all other occupations calling for the exercise of physical force. Two hours' necessary labor was extended over six days in the performance of that which was unnecessary. I don't know that Darrow thought it his duty, strictly en- joined on him by biblical authority, that I should earn my bread in the sweat of my brow. I was, nevertheless, physically so impressed ; and with the impression came the reflection that I had better husband my resources for bigger pay than sixty dollars per month. As on a former occasion, I took no time in severing this association, and, within a few days thereafter, found myself aboard Capt. T. 20 Life and Times of a Civil Engineer. P. Leathers' magnificent steamer Natchez, bound for the Crescent City, and thence pro- posing to embark for the city of Vera Cruz. At that time it was extensively published that the Mexican capital and the city of " The True Cross" were to be united by iron rails — that American Engineers were in great demand, and the pay of the poor devil who carries and uses the transit and level to be as high as five hundred to a thousand per month, while rod- men and chainmen were to receive double the amount of salary paid to bank tellers and cashiers. The temptation was grandly alluring to me, as, doubtless, it was to many others. I was full of the memories of Prescott's un- rivaled descriptions of the w T ealth and magnifi- cence of the Montezumas, and equally confi- dent that the Aztecs of old had but skimmed the surface of the mines of mineral wealth which nature had so bountifully provided. Riches had been found in the sands of Cali- fornia, and why not a speedy fortune, easily made, in a land whose temples were roofed with gold, paved with silver, and glittered with gems of purest ray and dazzling brilliancy ? The prospect was tempting ; but, meeting with an accident, a not unusual one, at any time or place, and r at all times, one of the most incon- Life and Times of a Civil Engineer. 2 1 venient and troublesome of accidents — want of money — my trip was indefinitely post- poned. Going back on the line of my journey, I found myself in Baton Rouge, the capital city of the Pelican State ; and, from this time and place, I should date the beginning of my engi- neering career, as it was then and there I was first clothed with the responsibilities attendant on a commanding position. The state was divided into four swamp land districts, and it was my good fortune to be ap- pointed, by the Board of Commissioners, En- gineer-in-Chief of District No. 1. I had reason to be proud of the distinction, as my official commission came just in time to congratulate me on my twenty-first birthday ; and having been long afflicted with a torturing uneasiness produced by chronic impecuniosity, I experi- enced as sudden and gratifying relief from this trouble as I would now, in 1893, if I could hold a capital prize ticket before the window of the paying teller of the Louisiana Lottery Com- pany. At this time Louisiana was in receipt of a large revenue, derived from the sale of lands donated by the General Government, which was appropriated to general drainage purposes, and the erection and maintainance of levees 22 Life and Times of a Civil Engineer. along the Mississippi and other streams within the state. The Commission having determined on the drainage of Cat Island, a section of country lying between the Mississippi River, Bayou Sarah, and the Tunica Hills, I was directed to this as my first work. A topographical survey demonstrated the im- practicability of complete and effectual drain- age, and I so reported to His Excellency, Gov. Robert Wickliffe, and the honorable Board. The legislative appropriation having, however, been made, it was deemed proper to expend it in the effort, though it might fail in the result. It should be observed that Cat Island was in- tensely 'and unanimously Democratic in its votes. Having secured, by a long line of levee, the lands from overflow by the waters of the river and Bayou Sarah, two iron boiler culverts, with self-acting gates, were placed in position at the lowest and most effective point for the drainage of rainfall accumulation during the prevalence of high water. No patent was taken out on this culvert, as its material and design were, doubtless, contemporaneous with the birth of the iron age ; but it is not thought presumptu- ous in claiming credit for the cost of the work, it being but nine hundred dollars — four hundred Life and Times of a Civil Engineer. 23 linear feet of boiler shells, and each culvert forty-two inches in diameter, while a perma- nency of twenty years added additional testi- mony, not only to its economy in outlay, but to its effectiveness in the accomplishment of such work as was expected. It is not the design of the writer to enter into lengthy details in speaking oi the various works of his district, as it certainly would add nothing to the interest of the memoirs of this book, while it might bring upon him the charge of vainly exploiting those things which every- body can do. To those who know me well, I have no apologies to make, as I have no fear of their imputing to me a desire to impress my readers with the idea that I am " learned in engineering above my fellows " ; while to those who might misconstrue my honest intent in in- diting these pages, and ungraciously think of me as one having no modesty, and, therefore, less merit, I can only say that they should lend me all their sympathies, and help me in writing a book in illustration of my Life and Times, and show me how to do so without much speaking of myself Following this work, I was next directed to locate the lines of a large body of timbered land belonging to the state — comprising about 24 Life and Times of a Civil Engineer. one hundred thousand acres, and bordering on the Amite, Blind, and New river and Lake Maurepas. This was by far the most difficult physical task that I have ever had to encounter, and all old sectional swamp-land surveyors must read- ily admit it as one that few of them ever under- took and accomplished. The entire country was under water, varying in' depth from one to four feet, and yet for sev- eral months the running of lines was continued, and the winding up of each day's work found every member of the party soaking wet from head to foot. Necessarily, the camp was, most of the time, from five to six miles from the field of opera- tions ; and those who have tried wading in water, though but knee-deep — and handicapped by heavy boots — the day's work having lasted, with but an hour's intermission, from early morn till sun-down, and the stomach turbu- lently rebellious, because of a short and hasty mid-day lunch — can not withhold their assent to the conclusion that no greater hardship in the way of surveying can be thought of that will so effectually test the endurance of a field party. The evident object of the survey was to pro- tect the lands from the depredations of the Life and Times of a Civil Engineer. 25 timber robbers who were engaged in the trans- portation of ash and cypress to the New Or- leans market.. What effect it had the writer has no means of knowing, but doubtless the illicit traffic has grown with the years. It may be of interest to timber men to know that this was the most compact and extensive brake of ash and cypress to be found in any of the Southern states ; and if it has not been too much culled, a saw-mill at the mouth of Blind river would prove a profitable investment. Next in order, because of the magnitude of the work, was the building of the Bonnet Carre levee. A crevasse had occurred at this place during the flood tide of 1858, and opened up a water-way from the river to Lake Pontchartrain of a mile or more in width. The gap was easily filled up, as ample provision was made out of the swamp land fund ; and the new line having been located at a safe distance from caving bank, and built in due season to permit of thorough settling of material before the coming of high water, it served the purpose of full protection till some time after the war be- tween the states. It is the w r riter's recollection that the crevasse was caused by a caving off of a part of the line of levee. If this be so, it is only an additional 26 Life a7id Times of a Civil Engineer. ' illustration of the negligence of some levee commissioners. But whatever was the cause of the crevasse which entailed so much of ruin and disaster on the people of the lower coast, it could have been prevented by the adoption of simple means and expedients ; and it is here contended that there is no good reason why levees should break, unless it can be shown that the annual necessities of the contractors demand that such should be the case. Doubtless, the positiveness of my assertion regarding the stability of levees will provoke a smile among those who have had much to do with the building of them, but when it is once conceded — as it must be, since fact will force it — that the material of all our levees, however small in cross-section, is ample, by a large fac- tor of security, to withstand the pressure of the water, it should be at the same time ac- knowledged that, if some expedient should be adopted to render the material impervious to water, and act as a successful resistance to the encroachments of woods-rats, crayfish, etc., we could secure for such structures as much permanency as could be expected from the piling up of Indian mounds. This could be accomplished by sinking gal- vanized sheet-iron plates along or near the center line of the levee. Life and Times of a Civil Engineer. 2 7 It is not to be inferred that any claim to originality is made in suggesting this device in the construction of levees, as it has been used in many that were erected to resist the impulsive pressure of sea waves, while defying the boring attacks of the numerous marauders of the briny deep. As a notable instance, at- tention is called to the Jersey flats. Previous to their reclamation, they had but a nominal value, but now furnish the most productive garden spots in the vicinity of New York City. New plans or devices in levee building have, perhaps, been thought of by many, while a few have obtained a general publicity without any practical indorsement. It is well known to the people of the Mis- sissippi and Louisiana bottoms, that the high levees over low marshy localities, are not only costly of erection and difficult to keep up, but require constant and unremitting vigilance in their guarding during high-water periods. It was during the political reconstruction era, and the reconstruction of the big Mor- ganza levee in the Parish of Point Coupe, La., that the writer called on and submitted to the Board of Levee Commissioners, at New Or- leans, a proposal to substitute wood for earth in the building of this line of levee. 28 Life and Times of a Civil Engineer. It had been contracted for and built the pre- vious season, at figures ranging from seventy- five cents to one dollar per cubic yard. Just think of it, you fellows who are greedy to get hold of a piece of work at any thing, from eleven cents downward, so that the commis- sary holds out and pays the usual dividend. It was shown that places of heavy fills could be well secured by the adoption of the wooden plan — the timbers used in building to be thoroughly treated by the Formanizing process for preserving them, and to cost less than half of the ordinary and legitimate price of earth- work. The practicability and economy of the scheme were admitted, but the writer was given no opportunity to demonstrate it on a contract, because the Board had, in its wis- dom, discovered that "some body might set fire to the levee and burn it up." Such was the conclusion of a day's deliberation on the part of these Solons. The king of levee contractors, as he was known in those days, owned the Board, and controled their votes, by the same means as are now so conspicuously and so successfully operated by the railroad lobby with honorable Senators and Representatives in our national legislature. While on this subject, and before dismissing Life and Times of a Civil Engineer. 29 it, it might be asked if the wooden-levee method has ever engaged even the passing at- tention of those having charge of the building and maintainance oi the long- levee lines in Mississippi and Louisiana. Considering the magnitude of the interests dependent, not alone on the integrity, but the skill and ingenuity of the directors of such works, it seems passing strange that some- thing has not been adopted in lieu of earth embankment, because of the many ineffectual attempts to shut out the Mississippi river from the beds of natural drainage therefrom, or other low and marshy localities, such as sloughs and lakes. The inevitable settling of material, when dumped into such places, goes on at such a rapid rate as to require a considerable change in the Engineer's estimate of cost — frequently quadrupling original calculations — and in the end, the mountain of dirt, saturated from top to bottom, and honey-combed throughout by myriads of destroyers that are indigenous to the swamp, trembles for a while on its weak foundation, when, giving way, under a pressure of eighteen to twenty feet of water, a vast area is deluged, and thousands and millions of prop- erty destroyed. It is evident that a levee of great height, ?o Life and Times of a Civil Engineer. j and of the usual and ordinary cross-sectional features, when erected on lines crossing these very low places, necessarily imposes a very great pressure on a very weak foundation. One of the consequences of this is seen in the spreading of the bulk of the earth employed in its construction. The material is generally of a mucky character, requiring a longer time for settling than the sandy loamy soils ordi- narily used in building lower levees. Fre- quently the flood of the river comes upon its slope long before the Irishman and his engine have ceased their work, and the consequences, as adverted to, come to pass. The above was penned some time before the public announcement that Mr. Chas. E. Wright had patented his " Levee Safety- Wall." Since reading the many indorsements of it, and particularly that of Mr. Murphy, who has tried it, and found it effective ; indeed, so far effective, as to bring from him a proclamation in the New Orleans Delta that he had used it for several years — under the most trying cir- cumstances — in the low marshy grounds below New Orleans ; and that he was going to con- tinue using it " regardless of the Wright pat- ent," I congratulate my inquiry of the Engi- neers who have charge of the Mississippi levees, Life and Times of a Civil Engineer. 3 1 why they do not adopt something that will prevent crevasses ? In a late issue of the Vicksburg Commercial Herald, the writer indorsed the Wright Safety- Wall as the best and most economical that could be adopted as a prevention of crevasses. It is of inch plank. The center, or inner plank, to stand vertically from the bottom of a muck ditch to two or three feet below grade of levee. Inch timbers to cross the vertical plank, on either side or both sides — longitudinally ; a continuous section being made by breaking joints ; thus making a strong section over a long span. Hydraulic cement being applied as a filling between the joints and surfaces. A -Levee Safety- Wall Co.," of which Mr. Wright is president, has been organized ; and it is the hope of the writer, as well as the wish of the thousands who have property interests in the valley lands, that the company may be given an opportunity by the several Levee Boards, or the Federal authorities, to prove the merit of the invention. It was during a very warm summer that, in connection with Fred Farrar, the Chief Engi- neer of the second swamp land district, I was engaged on the survey of the Lafourche valley. It is not to be thought that a complete 32 Life and Times of a Civil Engineer. survey of this entire section was accomplished in one season's work. It was merely begun by traversing the Mississippi from Donalclson- ville to Fort Jackson, and thence down the Lafourche bayou to Houma, beside the run- ning of several lengthy cross lines. We had with us, as a check-leveler, a com- rade who is now well known to the states — but perhaps better to that of the Lone Star — as what the Hon. J. Proctor Knott terms a com- mercial evangelist. The party should be quickly recognized by traveling men, when it is said that he has a pointer dog, wears a white slouch hat, dresses neatly, plays on the banjo, sings a good song, talks rapidly but well, and is, altogether, as good company as one could find in a day's travel. It is reported that all Texas chews his tobacco — that his commissions are heavy, and he is, altogether, bloomingly prosperous. So mote it be, for he was always a prince of good fellows. How often do we hear repeated the woeful experiences of swamp land surveyors, when telling of the miseries inflicted on them by the mosquito tribe. Why, my dear fellows, unless you have handled an instrument in the Parishes of Plaquemine and St. Bernard, you hav n't the slightest conception of the magnitude and voracity of that pestiferous insect. It was be- Life and Times of a Civil Engineer. 33 cause of these, and horse-fly blood suckers, that the Lafourche valley work was brought to a sudden close. That it has been continued and carried out, as originally proposed, I do not know. There is a large area of this valley that is irreclaimable, but a comprehensive survey of it would develop the fact that thousands of acres, by,a judicious system of draining and embank- ing, could be brought under the plowshare. Is it not curious that so much capital should now be employed in the digging of canals to penetrate the Everglades of Florida — through a section of country that is reeking with mala- ria — when lands equally as fertile, and requir- ing no more money nor ingenuity to redeem them, are to be had in the Teche country — the Eden of America ? Following this work was one of an attempted location of a tide-water levee. That it was not effected, was the result of combined resist- ance on the part of the horse-fly and mosquito tribes. They drove us from the field 'ere we had succeeded in placing an instrument in po- sition. Perhaps this statement will not be credited with being the full truth. To those who doubt, and are proud of their incredulity, it can only be said, go down and try it. " The proof of the pudding is in the eating." Brave Fred Farrar! He went to the battle 34 Life and Times of a Civil Engineer. fields in defense of his country, and met his death, heroically, at Murfreesboro ; and with him died another of the party — Adolph Kent. One was Lieutenant-Colonel and the other Adjutant of Gladden's regiment of Louisiana Regulars. It was about this time that one of my field associates, John Van Pelt, became engaged in a dueling difficulty with a Mr. Le Blanc. Be- ing solicited by Van Pelt to act as bearer of a challenge, I declined to second him in that ca- pacity, but persuaded him to permit of my of- fices as a peace-maker. Llaving failed in get- ting an apology from the other party, I stood aside, while James McDonald, the then editor of the Natchez Free Trader, and at this partic- ular time sojourning in Baton Rouge because of a shooting scrape he had had with another Mississippi editor, Bob Pnrdom, was selected to further conduct proceedings through the challenging and shooting phases. The parties met on the pegged line at Pass Christian, thirty paces apart, and emptied their shotguns of ounce balls. Fortunately no blood was shed. The combatants were men of nerve, and their friends had occasion to congratulate themselves that, after but one shot, matters were amicably adjusted. Van Pelt entered the Confederate service as Life and Times of a Civil Engineer. 35 a private. He was a native of Elizabethtown, New Jersey. He made a gallant soldier. By the bursting of a cannon at the battle of Shi- loh, he was afflicted with great deafness. Un- til within the last few years he filled the posi- tion of Chief Engineer of the State of Louisi- ana. It was during his occupancy of this office that he was promoted to a heavenly po- sition, for that he was a Christian his every act did testify. These were dueling days-, and two more of my friends sought the " field of honor" to ad- just a difficulty, and how unfortunate the re- sult ! This " adjusting practice " has been resorted to in all ages. Its advocates have speciously argued in its defense, while by far the larger majority of very good people have more rea- sonably condemned it. The writer, when a boy, back in the early fifties, was, with his two school companions, Jim Stetle and Henry Vick, delightfully en- gaged in camp hunting amid the wilds of the Deer creek and Sunflower country. And what a glorious time that was for game ! In those days the shooters of the creek — and "who were not shooters " could be more read- ily answered than "who were" — could see no fun in spending ammunition on coons, squirrels, 6 6 Life and Times of a Civil Engi7ieer. and mallard ducks, or even the strutting turkey cock ; such sport was too tame beside the chas- ing and killing of deer, and bear, and panther. We were initiated into the ways of hunting their favorite game by that brave and grand old Nimrod, Belcher. Is there an old settler along the Issaquena or Bogne Phalia who does not remember him ? Measuring six feet large in his stocking feet, full-chested, with square shoulders, bronzed vis- age, black, fiery, and determined eye, erect and graceful in his every attitude, warm and gener- ous in his affections, while terrible in his ven- geance, yet playful and frolicksome in disposi- tion, full of anecdote, and, above all (I state this as a reminiscence for the old, and as a rec- ommendation to the favor of the new denizens of that country), he loved all kinds of whisky, and was never known to be at the tail end of a crowd when they marched to the jug or counter " to take sugar in their'n," only he didn't take any sugar in his'n. Many a side-splitting laugh did we have as, lying in bed at night after a day's hunting tramp, we listened to his unbottling of anec- dotes, while Col. Vick, whom he was specially fond of entertaining, would pass the jug with "Take another, and tell another; you are bet- ter than a good story-book to these young fel- Life and Times of a Civil Engineer. 3 7 lows, and I really believe your yarns will cure me of my dyspepsia." "Yarns! did you say, Colonel? No, sir; I tell you, my life's a fact." And it was indeed a fact — a theme which, told by the magical pen of William Gilmore Sims or Fennimore Cooper, would reveal a his- tory wonderfully marvelous in its incidents, while impressively illustrative of one of the apparent paradoxes of Hie, that truth is stranger than fiction. The old man has long since passed away, but " Belcher's Bridge " and " Belcher's Scales " are yet to be seen, the one over Deer creek, formed by the falling and meeting of two large sycamore trees, clean, and slick, and limbless, full seventy-five feet above the stream ; and it was over this bridge of novel structure — built of two straining beams — that the hunter, with rifle slung over the shoulder, cooned it up and down in hot pursuit of a bear. The other a large cypress log, having one end firmly im- bedded in the muddy bottom of the Sunflower river, while the other bobs up and down, first under, then high above the water. A young man on his first swamp trip, which he was taking on one of the little "stern- wheelers" that navigated that river, seeing this cypress sawyer, was curious to know what it was, and on inquiring of Belcher, who was a 38 .Life and Times of a Civil Engineer. fellow passenger at the time, was told that it was his scales. " Why, Colonel Belcher," he further inquired, " what, in the name of sense, do you use them for?" " Why, you see," was the reply, ''these rafsmen up here got to stealin' so much of the state's timber, and there bein' no way to stop 'em from cuttin' it, I jus' went down ter our legislater at Jackson, and made it give me a 'sclusive charter to weigh all the timber that was floated out'er the Sunflower river. The state, you see, couldn't 'ford to lose all this valuable timber ; so the weighin' charges was put at a heavy rigger, and me and the state was to dervide. Well, since I put them scales in the river, I've made lots and cords of money — and 'praps the state would 'er made some too, if the timber had hel' out long enough." It was during this very happy hunting time that the difficulty arose between my two friends, which, in years long thereafter, termi- nated in a duel to the death. The result of the conflict brought grief and sadness not only to the immediate relatives of Henry Vick, but to another who, within a week from the day of the fatal encounter, was to have been made his wedded wife. Stith was my assist- ant engineer at the time, and I have often re- gretted not being present on the occasion of Life and Times of a Civil Engineer. 39 the renewal of the boyish quarrel. The origi- nating circumstances were, beside these two, known to me alone ; and I have always felt that I could have accommodated all differences, and thus prevented the hostile meeting which .took place on the Mobile race course. Vick was seconded by Col. A. G. Dickin- son, the gallant adjutant-general of Magruder in the late civil war, and now a prominent cap- italist of New York city — and Col. Locker- idge, of Nicaragua fame — while the friends of Stith were Tom Morgan and Frank Cheatham, of Baton Rouge. Stith died in Vicksburg during the siege of that city by the Federal army. He was a lieutenant, in charge of a river battery, at the time of his death. Following the Lafourche valley survey came that of the New river district. It was an ex- tensive one — from the Mississippi to the Amite river, and embracing Spanish Lake, Bayou Fountain, and numerous other streams that lie within its limits. This work occupied a large party during many months. The New river section was embraced within the boundaries of the once notorious Houmas Land Grant, and, at the time of the surveys, there was much excitement among the planters of Iberville and Ascencion Parishes, because of an attempt on 40 Life and Times of a Civil Engineer. the part of J. P. Benjamin and John Slidell, then representing Louisiana in the United States Senate, to have the title confirmed by act of congress. It is an interesting case, the particulars of which are all set forth by a de- cision of the United States Supreme Court, in the case of Slidell v. Grandjean. Then came a trigonometrical survey of the Mississippi river, from the upper end of the first district to the last cultivated lands in the lower portion of the Parish of Plaquemine. These surveys, and all others that were made throughout the First Swamp Land District, under my admin- istration, were kept up in a connected form, and the entire system of levels was referred to a common bench work, on the southwest cor- ner of the capital building, at Baton Rouge. Maps of the many surveys that had, for years, been in progress in the four depart- ments, were in course of preparation when the late war broke out — work being done on them up to the time of the passing of Forts Jackson and St. Philip by the Federal fleet. As such notes were not essential to the posting of our state authority or military de- fense, they were — not quickly — but hurriedly rustled into drawers and boxes. Where they are now, may possibly be known to Major H. B. Richardson, the present distinguished chief Life and Times of a Civil Engineer. 4 1 engineer of the state. Doubtless, however, they are stowed away in Washington City, with other and more interesting historical papers, which bear the signatures of Jeff. Davis, J. P. Benjamin, R. E. Lee, Joseph E. Johnston, Beauregard, and a host of colonels. I never knew, until after the war, how many colonels it took to prolong it from 1861 to 1865. The title seems to be one of common inheritance. I will risk the ring of the chest- nut bell by repeating the experience of a Phila- delphian, on his first trip, by an Anchor Line steamer, down the Mississippi. The boat hav- ing rounded to at a cotton shipping landing, our Quaker City gentleman stood on the boiler deck until the last bale had been rolled aboard — the bell tapped, and the boat was moving out from shore, when, observing a group of a dozen or more men astride their horses, watching the movements of the steamer, and bethinking himself of what he had heard of the number of titled people in the country — raised his hat, and, in a loud voice, shouted, " Good-bye, Colonel," when, to his amazement and amusement, every man lifted his slouch. Under the direction of Captain J. K. Dun- can, chief engineer of the state, I made a sur- 42 Life and Times of cv Civil Engineer. vey of Old river, between the head of the Atchafalaya and the Mississippi. The object was the improvement of the water way be- tween these points. Capt. Duncan's report to the state legislature suggested the closing of the mouth of the Red and the digging of a canal for slack water navigation from the Mis- sissippi — following the bed of a " dry bayou ' for a mile or two, and entering Old river about that distance below the Atchafalaya. Of the merits of the plan, for that time, I can say nothing, as I have no remembrance of any particular features that were developed by the survey. I have, however, a very distinct recollection of observing a very expeditious and practical solution of the navigable prob- lem, by a stern-wheel boat called the " New Era." ' While engaged in cross-sectioning the mouth of the river, the little steamer, coming up with a heavy freight, turned her head down stream, and went vigorously to work on a backing- wheel. It being a sandy bottom she quickly- cut a passage through the shoalest places, when, straightening up, paddled on an unob- structed way to Shreveport. The term Old river, is the local name of the old channel of the Mississippi at the mouth of Red river. At this point, and immediately be- Life and Times of a Civil Engineer. 43 low, the Mississippi formerly exhibited two great bends, the lower and greater of which was cut off by the State of Louisiana, and is known as the Roccourci cut-off. The upper of these bends was cut off at an earlier period by Captain Schreve, for the purpose of short- ening the navigable channel. The portion thus cut off is known as Old river. Red river discharges into this old channel, and the Atch- afalaya, which has an independent outlet to the Gulf of Mexico, has its source in this Old river, two or three miles below the mouth of Red river. Some time in the summer of '58 — in the month of August, I believe— I had presented to me, by an engineer friend, a prospect for obtaining a large surveying contract under Uncle Sam ; -certainly not less than one hun- dred townships in Nebraska. At that time General Ward B. Burnett, of Mexican War notoriety, was Surveyor-General of the Territory, and Mr. Delohnde, of Louisi- ana, was Register of the Land Office. The Register being a brother-in-law of the Hon. John Slidell, who was then representing Louisiana in the United States Senate, I had the good fortune, as a preliminary step, to ob- tain a flattering introductory letter to him from the senator's pen, and with this, and kind rec- 44 Life and Times of a Civil Engineer. ommendatory notes from the Hon. Tom Green Davidson, then a Congressional representative of the same state, I posted off for the Ne- braska prairies. The Kansas and Nebraska — Squatter Sover- eignty — Free Soil — Abolition — Pro-Slavery — or whatever name it may be remembered by — War! had, about this time, worn itself out; so far, at least, as marshaling big battalions on the field ; but the blue shirt and red shirt — con- spicuous and unmistakable designations of the side a fellow was on — could be observed along- every bend of the Missouri river. Outside the shirt two six-shooters and a bowie were sure to be seen ; and they were, doubtless, a very necessary rigging of the shirt, as ''grim visaged war' had not entirely "smoothed his wrinkled front." Some little personal matter might require explanation — instanter settlement — and each fellow needed to have a ready adjuster at his side. In other words, in this time of peace war was already prepared for. On the trip from St. Louis, up the Big Muddy, to St. Joseph, the lower, boiler, and hurricane decks of the steamer were crowded with peo- ple of all sorts ; and, to pass dull time away, I made many acquaintances ; but memory is oblivious of all names and features of those Life and Times of a Civil Engineer. 45 with whom I talked and smoked, except one fellow who played on me what, nowadays, is known as the Bunco or Confidence game. He was, in age, but a few years my senior ; of fine physical development, and possessed of conversational ability that was wonderfully cap- tivating. Having edited a pro-slavery paper, and commanded soldiers on many desperate fields, I was impressed with the fact that he was a brilliant writer and an heroic fighter. My destination was Nebraska City, and my entertaining man, as he informed me, was bound for the same place. In due time we reached St. joe, and as the stern- wheeler which was to take us on our journey beyond was billed to leave late in the afternoon, thus giving us sev- eral waiting hours to stroll around and see the sights, my friend suggested a ride out to his farm — about four miles from town — where I was to see his wife, " a true, noble and beau- tiful Southern woman," his waving fields of wheat and thorough-bred stock, and, having lunched, we would drive back to town, and, being refreshed, we could the better stand the crowded boat trip to Nebraska City. In an elegant vehicle, drawn by a prancing team, we made a rapid drive over a splendid road to the farm. And it was, indeed, a model farm, such as I wish might be built and kept 46 Life and Times of a Civil Engineer. up over every quarter section of our fair South- ern land ; but I fear the wish will ever remain a fruitless one, until we get rid of a labor that consumes more than it produces, and it shall be supplied by one that is industrious, intelli- gent and responsible. But having seen the wife whose grace and beauty had been so lovingly depicted by my hospitable friend, I thought of the broad green acres as but glittering baubles in com- parison with his spousal possession, So rare was her beauty, And so charming her face. Just imagine what Bulwer or James would say, in picturing a lovely woman, and relieve me of a very large difficulty just here. Having partaken of a lunch that was ele- gantly and luxuriously served, we returned in haste to St. Joe, and arrived in time to hear the ringing of the boat's second bell. The team was quickly surrendered into the hands of a livery boy, and we bent our way toward the steamer. We had not, however, proceeded very far when my companion sud- denly remembered that he owed a gentleman, around the corner, fifty dollars. His money was in his trunk aboard the boat — he would Life and Times of a Civil Engineer. 47 not have time to make two trips before the boat left, etc., etc., etc. —just loan him the amount, and he would be on hand before the boat shoved out. Of course I loaned the amount without hesitation. To reach the steamer was but a few minutes' walk. Comfortably seated on the outer deck, smoking a Western cigar, reflecting on the kind and generous attention which had been shown me by such nice people, and congratu- lating myself on having as a fellow-passenger my ci-devant friend, as far as Nebraska City, I did not realize, till looking at my watch, that an hour's time had passed since returning. Now the captain's pulling the bell-rope ; stage is or- dered hauled aboard ; last, departing tap of bell — and yet Jack Henderson is not in sight ; and Jack never did turn up, so far as I know. The trip onward was accomplished without accident to life or limb, though the little boat had many twists among the snags that studded almost every bend of the upper river. My introductory letters gained me a cordial welcome from the Surveyor-General, and, soon after meeting with him, I was invited to a prairie ride in an army ambulance, with himself and a one-armed Major of U. S. Infantry. The ambulance had been trotted along two or three squares, when it was halted in front of 48 Life and Times of a Civil Engineer. an unpretentious, California-built shanty, over the door of which swung a sign of WEL- COME. The inner man having been temporarily sat- isfied at the counter, and a half-dozen bottles of " saddle-bag cocktails " deposited in the army wagon, we went rolling along an undu- lating prairie road for, perhaps, a mile or two, when the Surveyor- General perpetrated what might be called that old Gubernatorial chest- nut, and — there was but little left of one bot- tle ; this one, however, got me the promise of ten townships. The increase in promise, how- ever, only counted by arithmetical progression to the emptying of the last bottle ; and, on our return to town, I found it optional to take or refuse fifteen townships. I was not long in de- termining the matter, as business at home was more profitable than such a contract. On the homeward journey — making the ac- quaintance of two surveyors- — "old timers," as they let me know — I was informed that I could employ such as they were for $75.00 per month, and that they would guarantee to run up a crib each a day. On asking to be enlightened as to the mean- ing of that new surveying term, the " old timers " expressed surprise that a man propos- Life and Times of a Civil Engineer. 49 ing to handle a hundred townships contract should not know that much. A crib comprises a north and south row of sections, from the south to the north boundary line of a township ; making an actual line run of eleven miles, and a walk of sixteen miles (interior sectionizing). A few moment's re- flection convinced me that I should have closed with the offer of the Surveyor-General, and hired my crib men to do the work, thereby making a very respectable profit out of the fifteen townships. It seems, however, that a crib a day was nothing compared with the amount that could be done, and done, too, without much outfit or undue exertion. All that was necessary, according to the statements of my surveyor acquaintances, was to provide a light wagon and team, a tent or two, provisions, and a few et ceteras — some few jolly fellows— shot guns and plenty of amuni- tion, and a seven-up deck ; camp out, and have a good old time ; only running a few miles and locating a few corners. Expenses would be almost nothing — all feed and no work — and, when a reasonable time had passed away, notify the authorities, by sending in a nice set of field notes, that the contract was complete, and call for an immediate inspection. 5 t^jc y(s vpr After occupying myself, in connection with Mr. 'George D. Stonestreet, in general en- gineering and surveying in Birmingham, Ala., the magic city of the South, for a year or more, I next moved to Kansas, where I was employed, during a winter season, by Captain A. W. Gloster, the then Chief Engineer of the Kansas City, Wyandotte and North-western Railroad. My stay in this State was of such short duration that I have nothing to relate of an en- gineering experience. I had heard so much of the great and grow- ing State of Kansas — its climate, productive- ness, varied industries, its many churches and school-houses, and the general intelligence of its people — that I was prepared to see some- thing that I had never seen before ; and I did see it, but not as Emigration Agents had ad- vertised it. The thermometer, on the day of my arrival, registered twenty-eight degrees below zero, and so continued, with no material variation, so far as comfort was concerned, for several months ; while the wind blew with almost hur" ricane velocity. This is one beauty of the cli- Life and Times of a Civil Engineer. 1 09 mate. I left in the springtime, and therefore missed a delicious summering in that mild lati- tude. I am told that it is blissfully inviting at that season of the year. When the topmost thermometrical gradua- tion is almost reached, and you are sweltering under a red-hot sun, and thirsting for water, there comes along a gentle breeze which, in other states, brings cooling comfort and re- freshment ; but this is a Kansas breeze — and it burns and parches you. The United States Census averages its corn production at thirty bushels per acre. A ne- gro's mule would laugh at the task of making such a crop in the Mississippi or Louisiana bottoms. Its industries are not comparable to those of Georgia, or even Alabama. But, as to the number of its churches and school- houses, it is bountifully supplied — and it needs them. It has more religious denominations, so-called, than any other two states. You can see a school-house on nearly every square mile, but, withal this, the general knowledge and in- telligence of the state that, only recently, the Kansas Legislature wanted Congress to put under martial law — Arkansas — is far beyond the people of Kansas who claim so many edu- cational aids and privileges. Of the masses, it may be said, that their ignorance borders on i io Life and Times of a Civil Engineer. stupidity, and their bigotry and intolerance are of the most sickening order. I have said, in the beginning of this book, " Occasion will be taken, in the course of these pages, to particularize some of the results al- luded to," etc. Subsequent reflection, how- ever, has concluded me to go back on the promise, as, in attempting to fulfill it, in its original intent, I should be obliged to mention names — for the owners of which, in their per- sonal capacity, I have high respect — and what- ever may be my estimate of their professional worth, is a matter of no concern to the general public ; and, while refraining from such publi- cation, I will be adhering to that ethical code of the fraternity, which should not be disre- garded. . I will, however, say this much, that the proper adaptability of means at hand never fails of legitimately corresponding results. This is not only true of mathematics, but may be asserted of the various commercial and practical enterprises of the world. The right use of the means is the determin- ing factor in producing beneficial results. The Engineer having charge of the building of an important line of several hundred miles of rail- road may be backed with ample capital to en- Life and Times- of a Civil Engineer. 1 1 1 able him to construct the road ; and this may be done regardless of economy in location and construction, while another have so little of pecuniary backing as to prevent the employ- ment even of the field assistants, demanded by the convenience and necessities of the surveys (and made distressingly: anxious concerning the payment of his own small salary), yet gives due consideration to every surveying item', and from it determines a location on true engineer- ing principles. The writer has no hesitancy in proclaiming that the contracted engineering as indicated in the above paragraph had its practical counter- part in the location of an important line of rail- road with which he was connected, and his suggested but rejected plans have been ap- proved by many Civil Engineers of unques- tionable competency. The results alluded to are conspicuously ex- posed on every hand, and the practical eye finds no difficulty in discerning them. In concluding this short narration of the " Life and Times," I think it a duty I owe to the many comrades who have faithfully toiled along the hard road of "out-door" Engineer- ing, and to the profession at Targe, to protest against the money estimate of their services. 112 Life and Times of a Civil Engineer. While it must be admitted that, as a science, there is none of higher rank than that of Civil Engineering ; and that, to an attainment even of such elements as will enable the Engineer to comprehend its simplest works, years of mental, and, in most cases, physical labor of the most arduous character, are required, it can not be denied that, of all professions, it is the most poorly paid. This undervaluing of such service was begun, and is now continued, by those of the profession occupying more or less high positions. The salary of competent- field Engineers ranges from sixty to one hundred dollars per month ; many of them more thor- oughly acquainted with the work they have to do than the one who thinks it labor merely to sign their papers ; and yet the latter is paid by the thousand per month. Why do n't these small salaried fellows climb to the top rung of the ladder ? Because money and influential circumstances, uncoupled with true merit, push so many up that ladder that the worthy ones can only look up. THE TRUE THEORY OF THE MISSISSIPPI RIVER.

The actual drainage below Red river, during sixty days of the high water of 1851, was, therefore, very nearly the eighteenth part of the total annual downfall over the whole area of the Mississippi Valley. The value of the drainage during these sixty days, reduced to inches, is 2^^. Now let it be supposed, that, from any cause as to the tillage of the prairies, the destruction of the vegetable growth, or the better drain- age of the fields, out of the forty inches of rain which falls, two-fiftJis of an inch, or nearly one per cent of the whole, should be discharged into the Mississippi in the course of these sixty days of flood, over and above the present average discharge. If this slight increase of the total discharge were distributed . uniformly over the whole period of sixty days of high water, it would require that the channel of the river should be competent to give vent to an in- Life and Times of a Civil Engineer. 1 1 7 creased volume equal to 220,000 cubic feet per second ; and the result would be an increased elevation of high water of six feet. This con- clusion is derived from an approximate deter- mination of the increased height of a flood, due to any given increase in the volume discharged, when the general dimensions and slope of the river are given.. The average depth of the river at high water of 1850, in mid-channel way, from Vicksburg to New Orleans, was one hundred and fifteen feet, while the area of high water section from Vicksburg to Donaldsonville was 215,200 square feet. The general slope, at high water, between Red river and Donaldsonville, being" taken at twenty-five hundredths of a foot per mile, the working of the accepted formula, for the de- termination of mean current velocity, shows 4,584 feet per second, and a discharge of 985,560 cubic feet per second. But if the surface should rise twelve inches higher, in consequence of an increased supply of water, the depth would become 1 16 feet, the slope about tVi/V feet, and the area of the average section would be increased to 218,300 square feet. The working of these new ele- ments gives an increased discharge of 1,015,- 640 cubic feet per second. This shows that 1 1 8 Life and Times of a Civil Engineer. the average volume which must be supplied to the channel, when in full flood, in order to raise the surface one foot, to be 30,080 cubic feet. The average volume of 35,000 cubic feet per second has been assumed as a result applica- ble to the general or average dimensions of the Lower Mississippi. No rule can be given which will apply to every position ; for the width, depth, and area of the stream are most variable ; and as the same volume of water must pass through different sections, its veloc- ity, both surface and mean, must be subject to continual change. A great flood is the result of a simultane- ous discharge of the great tributaries, which usually run off successively. The high water produced by the Red and Arkansas rivers, in the ordinary course of things, has begun to subside before that of the Ohio, Cumberland, and Tennessee comes down ; and these, again, begin to recede be- fore the Mississippi discharges its volume ; and this, in its turn, subsides before the snows of the Rocky Mountains, which swell the northern tributaries of the Missouri, are melted by the tardy sun in those high latitudes, and the wa- ter has had time to flow through the three thousand miles of channel intervening between Life and Times of a Civil Engineer. 1 1 9 the sources of the distant streams and the head of the delta. It is a part of the natural order of events that these great rivers shall discharge suc- cessively. But there were, doubtless, in former ages, as now, exceptions to this natural rule ; and a meeting of the flood-waters of distant tributaries may have occurred many a time in the course of the tens of thousands of years which have witnessed the formation of the delta. Such things may occur hereafter, and greater floods than have yet been seen by men may be felt along the banks of the Mis- sissippi. The floods which now carry annual distress and destruction into the Lower Mississippi, are the result of artificial causes. The water is supplied by nature, but its height is increased by the works of men. The prominent cause is the extension of the levees. The Mississippi has been accustomed to find vent for its surplus waters in the vast swamps which are to be found along the valleys of Red river, the Arkansas, White river, the Yazoo, and the St. Francis ; and to the right and left of its proper course, almost the entire distance from Cape Girardeau to the Belize. In the progress of the levees no regard has been paid to those bayous, or natural outlets, 1 20 Life and Times of a Civil Engineer. through which the Mississippi, in its unre- strained condition, vented, as it rose, a large portion of its surplus water. The numerous channels through which the rising floods were safely discharged into the swamps, with few exceptions, have been all stopped by the extension of the levees across their mouths, consequently that portion of the flood which these openings allowed to pass into the great reservoirs of the delta, has been ex- cluded from them, and is now forced, when the levees stand firm, to flow between the artificial banks down the main channel of the river. It will be readily perceived how this com- pression of that surplus water which, in the original condition of the stream, spread over a width of fifty or one hundred miles of inun- dated country, within a channel of half a mile in breadth, will cause the flood to rise higher. Shall the river be restored to its original condition by reopening the closed outlets, and again allowing the water to pass out through its natural vents ? This is now wholly im- practicable. The bayous are all types of the Mississippi itself. They originally received their supply from the river, and, in extreme floods, were subject, like the river, to overflow their borders. Naturally, as on the main river, these overflows left their deposits. To open Life and Times of a Civil Engineer. 1 2 1 all these bayou outlets would lead to certain and immediate destruction of great interests. What will be the effect of the levee system above when it shall be prosecuted to such an extent as to fill up all the gaps above Red river ? That we may have a more definite idea of the consequences that will result from the ex- clusion of the water from a given portion of the swamps, and confining the volume so ex- cluded to the channel of the river, when the Mississippi has already overflowed its banks, and is pressing on the levees, let's figure some more. It has been stated that the swamp lands of the delta are supposed to cover about 40,000 square miles. But if we confine our attention to that portion of this area which is found above the mouth of the Red river, we may es- timate its length, northwardly, at four hundred miles, and its average breadth at about sixty- five miles, dimensions which give for the total area of inundated lands north of Red river, 26,000 square miles. If we assume that the water over the whole of this area is excluded from the swamps to a sufficient extent to reduce the depth of over- flow only twelve inches, we shall have for the additional volume which, by that process, will 122 Life and Times of a Civil Engineer. be forced into the river, and which must, there- fore, be carried off by the channel. 26,000X5, 28o 2 = 724,838,400,000 cubic feet. This additional volume must be discharged through the channel of the river in the ordi- nary period of high water, which is assumed to be .sixty days. The increased discharge through the channel due to this cause, will then be 12,080,640,000 cubic feet per diem, and, conse- quently, 139,822 cubic feet per second. This is about the one-seventh part of the ac- tual high-water discharge of the Mississippi below Red river, as previously shown. But, it having been shown that if only 35,000 cubic feet per second were added to the high- water discharge, the surface would be raised at or above Plaquemine fully one foot, it follows that by reducing the depth of over- flow throughout the swamps above Red river only one foot, the high-water surface below Red river will be raised nearly four feet for a period of sixty days. •In the above calculation, it has been assumed that the depth of overflow, prevented by the levees, is but twelve inches. From the best Life and Times of a Civil Engineer. 1 2 data obtainable, it is estimated that five feet is about a fair average for the depth of the inun- dation, distributed over the total area north of Red river, which is subject to overflow. It follows, therefore, that whenever the levees are made to stand firm and exclude all the water from the swamps, the quantity so excluded will be equal to five times that above obtained, or sufficient to require an increase of discharge through the channel, of 699,110 cubic feet per second, kept up for a period of sixty consecu- tive days. The actual discharge of the Mississippi in extreme high water, in 1851, below Red river, was 1,134,000 cubic feet per second. It fol- lows, therefore, that to fill up the computed area of the swamps which are found above the mouth of Red river, to an average depth of five feet, will require a supply from the over- flow of the river equal to 700,000 cubic feet per second for a period of sixty days, or equal to the total high water discharge of the Missis- sippi for a period of thirty-seven days. In other words, if all the water which passes through the channel of the Mississippi below the mouth of Red river, when at its highest point, were discharged into the swamps above Red river, it would require a period of about thirty-seven days to fill up all those swamps 124 Life a?id Times of a Civil Engineer. to an. average depth of five feet. And, there- fore, on the other hand, if that portion of the Mississippi floods which is absorbed in filling up the swamps, were entirely excluded from the swamps, by a system of substantial levees, and forced into the channel — when an increase of 35,000 cubic feet per second will cause an increased elevation of surface of about one foot — the 700,000 cubic feet per second, so ex- cluded, would raise the surface about fifteen feet above the present high water marks. Let it be conceded that the abrasive force increases with the volume of water transported, and that the channel is enlarged as the abrasive force is augmented. The scouring force of the river can not be increased until after the surface has been raised ; and, therefore, after the damage from overflow has been done. When the bottom will be washed ont deep enough, and the banks will have caved in far enough to accommodate the total drainage of the Missis- sippi Valley, is beyond the prescience of science, or the light of experience, to foreshow. When the volume discharged by the river is increased, the channel will, no doubt, undergo a gradual enlargement ; but more than a thou- sand miles of material must be excavated and transported, re-deposited, re-excavated, and again transported many hundred times ; and Life and Times of a Civil Engineer. 125 there is no reason to doubt that hundreds, and, perhaps, thousands of years will be required to accomplish, by the levee system, the re- clamation of the Mississippi delta lands from overflow. It is contended that the construction of levees in the upper part of the river can not increase the floods essentially below, for the reason that the channel below is larger than that above, and can, therefore, vent between levees all the water that can be brought down between any new levee which may be built above. There are portions in the upper divisions of the Mississippi which are much larger than other portions below the Yazoo. The Missis- sippi, when in flood, discharges more water im- mediately beloiv the mouth of the Ohio than it does at a7iy point in the neigJiborhood of Red river. It is said that the water which is now dis- charged into the swamps above, passes through those swamps and reappears at their outlets, and aids in swelling the flood in the river below. But this is at war with the facts. The flood in the river travels faster than the flood in the swamps ; and the highest rise at the mouth of the St. Francis is not produced by the water of overflow which entered those 126 Life and Times of a Civil Engineer. swamps above and is drained off by the St. Francis ; nor that at the mouth of the Yazoo by the water which is drawn through the swamps of the Yazoo ; nor that at the mouth of Red river by that which is discharged by the Cocodrie and the Tensas. The floods of the Mississippi are produced by water which does not go into the swamps at all, but which de- scends through the main channel of the river, aided by the discharge received from the tributaries on the way. The height of the flood at any point depends on the volume that is brought down by the river and its tribu- taries, and not by the discharge from the swamps. But, after the river has attained its height, the supply is kept up, and the duration of the flood prolonged, by the subsequent dis- charge from the swamps. It is not unreasonable to assume, that if it be in the power of the government to so control the waters as to add to the height and violence of the river, it will be equally within its power to reduce its force and moderate its velocity ; and that, too, without impairing its navigable channel way. The total steam power engaged in navigat- ing the Mississippi and its tributaries is about equal to 600,000 horses ; adequate to the lift- ing of all the water discharged by the river Life and Times of a Civil Engineer. 127 and its outlets, at the moment when this dis- charge is greatest, as fast as it comes down, to a height of four feet. It is evident that these floods can be restrained by mere mus- cular strength, by steam power, by a dead lift, and without the aid of any resources which are supplied by art and experience. But great volumes of the Mississippi floods may be dis- charged directly into the sea, by merely remov-. ing a portion of the artificial embankments which now confine them to the river, while the floods may be controlled by retaining a portion of the waters in the valleys above. Right here we are met with the objection, that the river will be shoaled below the site of the outlet. The Mississippi and its natural outlets are now greatly overburdened in times of extreme high-water, and are unable to vent the volume which is forced into them by the distant tributaries as fast as it is brought down. This excess of water finds new outlets by over- flowing the natural banks, or through crevasses in the artificial levees. Outlets then, acting only as high-water vents, through which this surplus water may be let off, can not possibly dimin- ish the actual area of the river's section be- low; for such outlets will discharge water which does not pass through the channel at all. The water which injures the country is 128 Life arid Times of a Civil Engineer. not that which descends between the natural banks, or even that larger quantity which now descends between the levees of the Mississippi, but is precisely that which, after the levees have given way, leaves the river and spreads over the cultivated fields. This portion, there- fore, may be discharged through the artificial openings leading to the sea, without affecting the area of the channel below ; for it does not now, and never did, flow through the channel, and can have, therefore, no influence whatever on its condition. In consequence of the extension of the levees above, the volume discharged by the floods of the Lower Mississippi will be annually in- creased. In opening outlets below Red river sufficient to give passage to this increased supply as it comes, the efficiency of the channel can not possibly be impaired, for this increased dis- charge has had no part in the creation or maintenance of the present channel. To the extent then, in the first place, of dis- charging the waters of overflow, or the crevasse water ; and to the further extent of providing for the increased discharge which the new levees will occasion, artificial outlets may be employed without the least apprehension that Life and Times of a Civil Engineer. 129 the present area of the river will be diminished by success. About eleven miles below the city of New Orleans, and one hundred above its mouth, the Mississippi approaches within five miles of the Gulf of Mexico. The ground between the river and the gulf, here known as Lake Borgne, is a plane sloping from the river back to the sea. The first three thousand feet from the river is cleared and highly cultivated land ; but the residue of the distance is swamp, always wet, and sometimes completely overflowed by the high water of the gulf. When the Mississippi is in flood, its surface stands six feet above the level of the adjacent soil, and at this point the levee is about six feet high. At the distance of half a mile back from the levee, the surface of the- ground is 9^ feet be- low the high-water surface of the river. At the distance of a mile, it is 10^2 feet, and so continues, almost a perfect level from that point back to the borders of the lake, where the surface of the swamp or prairie is 10^ feet below the high water of the Mississippi, as it stood in April, 1851. The average fall of the surface, from the river back to the level of the gulf, was found to be 2} feet per mile. The velocity of the 130 Life and Times of a Civil Engineer. surface current would be 5 feet per second (if the opening were made suddenly). If the levee were removed along a space of 5,000 lineal feet, the area of the outflowing column would be 52,500 square feet, and the discharge, con- sequently, about 210,000 cubic feet per second. It is reasonable to suppose that it would be practicable to form a vent at this point that would in a short time obtain an average depth nearly or quite equal to the difference between the high-water level of the river and the bot- tom of Lake Borgne near the shore, or about 14 feet, and that such an outlet would produce a reduction of the surface of the Mississippi at high-water, of not less than four feet, suffi- cient to secure the protection of New Orleans and the whole coast below the city ; and to some considerable distance above, for a very long period. All the water that is drawn off at this point, and all the reduction of surface that can be ef- fected by this outlet will be productive of good. There is here no interest to be injured but that of the few individual proprietors whose estates would have to be appropriated, and to whom, of course, compensation would have to be made. As to increasing the bars at the mouths of • Life and Times of a Civil Engineer. 131 the Mississippi by the withdrawal of a large volume of water from any part of the channel, it was clearly shown in a report to the War Department, by Mr. Ellet, that these bars are not produced by the destruction of the velocity of the river, where the fresh water meets the sea, but by the refluent under-current \ which is set in motion by the outpouring floods of the Mississippi. That the bars at the em- bouchures of the passes, can not be reduced in height by increasing the velocity of the river over them, and will not be increased in height by reducing the velocity. On the contrary, if the river could be made to discharge a large portion of its burden by some other channel, the depth upon the bars would be increased by the action of the sea, which would then set higher up, and if the river could be turned off entirely, and let into Lake Borgne, the bars which are thrown out by the Mississippi, and maintained in the deep water of the gulf by its power, would be swept off by the waves, when a heavy sea would set into the mouth of the river, unresisted by a descending flood. The Bayou Plaquemine should be enlarged, and the x^tchafalaya should be made the drain- age course for the waters of Red river. Next to the Lake Borgne outlet, the Atchafalaya would be the most important, because it would 132 Life and Times of a Civil Engineer. draw off the waters at the highest accessible point on the river. I have quoted, at some length, from Charles Ellet, one of the most scientific, practical and distinguished civil engineers of his day. The above extracts, from his great work on the Mississippi river — published in 1853 — are es- sentially verbatim ; and it is right that they should be so made, as no one has ever more intelligently investigated the Great River prob- lem, or published views respecting it, more lu- cidly or more logically. The book is commended to those who rely on the levee or jetty system alone for the re- clamation of the delta lands from overflow. Mr. Ellet does not attack the levee system. It is one of the means that must be used, in connection with the outlets, for a partial pres- ervation of the low lands from inundation by the floods of the river. I quote further from this eminent engineer, who, after suggesting various plans necessary to be adopted, concludes as follows : " But, while recommending these prompt and vigorous measures, it is the duty of the writer to express his conviction that, after all these means of relief — carried as far as pru- dence and a proper regard to economy and the interests upon which this excess of water will Life and Times of a Civil Engineer. 133 be turned — have been exhausted, they will be found insufficient to secure even the State of Louisiana against the floods which, at no dis- tant day, will be poured down the Mississippi ; while the great area, subject to inundation, in the States of Arkansas and Mississippi, can receive no sensible relief from any of these ex- pedients but that of levees. " To secure the whole delta it will be necessary" to commence promptly and press vigorously the great work of retaining the water in the mount- ains. " We come then to the question which is to be decided by the enterprising men and reflect- ing minds destined hereafter to cope with this vast subject. Shall the upper states go on to construct their levees, and raise them higher and higher, as the water is found to rise in con- sequence of their construction — endeavoring to overco7ne by levees the difficulties mainly produced by levees — doing work, daily, which will inevit- ably lead to the necessity of more work to render that work secure — or shall they begin to adopt, in connection with that which pro- duces so much incidental damage, a system of protection which, at every step, will do some good service to every interest ? Shall it con- tinue to be the policy — the favored and exclu- sive policy — to make whole provinces and 134 Life and Times of a Civil Engineer. counties depend for their salvation on the per- fection of every part of several hundred miles of embankment ; and to force every individual to seek to protect himself against the efforts of every interest above him? Shall this sys- tem continue until the artificial banks of the Mississppi shall rise in height with those of the Po, and the populations in the low lands, be- hind the intrenchments, along a coast of more than a thousand miles, shall be in hourly dread of crevasses of which the force will then be irresistible ? In short, shall the aid of Con- gress continue to be invoked, and the legisla- tion of states to be directed, to the indefinite prosecution of a scheme which adds to the present distress at every step of its progress, when the same results may be ultimately ob- tained by a process which harmonises every in- terest and does good to all, which will, at the same time, protect the entire coasts of the Mis- sissippi and the banks of its tributaries ; re- claim the swamps of the whole delta, and im- prove the navigation of every river of which the floods are received by the Mississippi. " But it may be asked when is this work to be commenced, and how is it to be prosecuted, to accomplish visible results over a field so im- mense, in any reasonable time ? The public mind has yet to be convinced that it is even Life and Times of a Civil Engineer. 135 practicable to retain a sufficient volume of wa- ter in the mountains to reduce the floods in the Mississippi any sensible amount. It has, it may be added, yet even to be persuaded to reflect upon the practicability of the sugges- tion. In the view of those accustomed to ad- vocate and conduct difficult enterprises, it is precisely the persuasion and conviction of the public mind of the feasibility of a measure, that constitutes its difficulty. When men re- flect on any thing which has a solid basis of truth, they have arrived near the point of con- viction. "It is not difficult to show that, to reduce the floods of the Mississippi one foot, we must draw off, or retain in reservoirs, about 20,000,- 000,000 cubic feet per week ; and that, to re- tain this volume, will require a reservoir 1 10 feet deep and covering seven square miles. Consequently it would not be difficult to show, that, to reduce the floods twelve inches for a space of sixty tlays, would require that nine such reservoirs should be applied to that pur- pose. It would not be difficult to show that these reservoirs would retain water enough to maintain the navigation of as many of the most valuable rivers that flow into the Missis- sippi from the east ; but, to bring the proof in detail, will require surveys ; and to obtain such 136 Life and Times of a Civil Engineer. surveys, will require the confidence and action of Congress. " But when the minds of men are directed to the fact that floods are increased by the de- struction of the natural reservoirs of the delta, it will not, perhaps, be difficult for them to ap- preciate that they may also be reduced by the creation of artificial and better reservoirs to re- place those that are destroyed. Under the operation of the causes which have been explained, the course of nature has been disturbed, and floods once regarded as exceptions to the usual order of things, are now of almost annual occurrence. Under the operation of human agency, and nothing else, the waters have been and are still being di- verted from their course, and concentrated in the great rivers ; and it is now proposed to counteract the hurtful effects of this diversion, by works of art, calculated first to restore, and ultimately to improve, the natural regimen of streams. It is proposed, in short, to construct new reservoirs to receive the increased drainage produced by the plow, and to compensate for those reservoirs which have been and are about to be destroyed by the spade ; to sub- stitute for the swamps, which have already re- ceived the water oi overflow, capacious lakes Life and Times of a Civil Engineer. 137 in the rock-bound valleys of the Allegany and Rocky Mountains. It would seem to be useless to demonstrate that such reservoirs will be cheaper and more efficient than the reservoir which has been formed by the river itself, by the levees, and which can only be made secure, by the maintenance of from two to three thousand miles of embankment, reared on a soil always liable to slip and to be under- mined by the action of the pent-up water. "Every effort should be made, while new vents are being opened and guard levees con- structed below, to retain the surplus water in the lakes at the sources of the Mississippi and Missouri, and along the course of Red river ; while proper sites for reservoirs should be sought in all the appropriate valleys of the Alleghany, and ultimately those of the Rocky Mountains. Surveys should be promptly insti- tuted at the sources of the Monongahela, Alle- ghany, Kanawha, Cumberland, and Tennessee, and other tributaries of the Ohio, for the pur- pose of ascertaining the most advantageous sites for great reservoirs that will discharge through their respective channels. That, in the selection of these sites, regard be had pri- marily to the supplying of the Ohio and the greatest of its navigable tributaries with water in the summer months; using the reservoirs 138 Life and Times of a Civil Engineer. for the double purpose of withholding the flood-water from the Mississippi when that river is overflowing its banks, and supplying the water so withheld to the Ohio itself, and its navigable arms, when their navigation is impeded by droughts. "That these surveys be extended promptly to Red river and its tributaries, for the twofold purpose of applying the great lakes with which that valley abounds to keeping back the floods, and relieving summer navigation from obstruction, by allowing the surplus so retained to pass down in the season of low water. The lakes in the valley of Red river may be turned to good account in the prosecution of this plan ; and the valleys of its tributary streams are understood to afford remarkable opportun- ities for the creation of great artificial reser- voirs. "The flood of 1849, by the destruction of the cotton crop of Red river alone, was pro- ductive of damage to the amount of five or six millions of dollars, while less than half of this sum would probably have sufficed to create reservoirs sufficient for the permanent protec- tion of all its valley, and the great relief of the Mississippi delta from the mouth of Red river to the sea. " It is recommended that attention be first Life and Times of a Civil Engineer. 139 given to the control of the great navigable tributaries which pass through the most highly cultivated portions of the valley of the Missis- sippi, because on these a double service can be performed — the navigation can be improved while the floods are arrested. But it is to be recollected that, while this motive prompts us to look to the distant arms, it is particularly those streams which, like the Washita and the Cumberland, discharge' nearest the point of suffering, that add most injuriously to the height of the floods of the Mississippi. " It is not at all necessary to keep watch upon the reservoirs to see that they perform properly. It is perfectly practicable so to ad- just their apertures that they may discharge constantly and almost uniformly ; filling up when the flood comes down and the supply is in excess, and falling again when the sources of supply begin to fail. The system, when fully carried out, will be almost self-regulating." 3/ ~^ ••
