Excerpt from Allowable Pressures on Deep Foundations The piers Of the Cincinnati Suspension Bridge are founded on a bed of coarse gravel 12 feet below low water, although solid limestone was only 12 feet deeper; if the friction on the sides of the pier be disregarded, the maximum pressure on the gravel is 4 tons per square foot. The piers Of the Brooklyn Suspension Bridge are founded 44 feet below the bed of the river upon a layer of sand 2 feet thick resting upon bed-rock the maximum pressure is about 55 tons pea° square foot. At Chicago sand and gravel about 15 feet below the surface are successfully loaded with 2 to 2g tons per square foot. At Berlin the safe load for sandy soil is generally taken at 2 to 2§ tons per square foot. The Washington Monument, Washington, D.C., rests upon a bed of very fine sand 2 feet thick underlying a bed of gravel and boulders the ordinary pressure on certain parts Of the founds tion is not far from 11 tons per square foot, which the wind may increase to nearly 14 tons per square foot.

Elmer Lawrence Corthell was born on September 30, 1840 in South Abington (now Whitman), Massachusetts, United States, the son of James Lawrence and Mary Gurney Corthell.
Corthell prepared for college at the South Abington high school and the Phillips Exeter Academy and then entered Brown University in 1859. He was graduated in 1867, taking the degree of Master of Arts a year later.
At the outbreak of the Civil War Corthell enlisted as a private in the 1st Rhode Island Artillery, serving for the period of the war. He left the army with the rank of captain.
In his youth it was Corthell’s desire and intention to become a Baptist minister. His health made it advisable, however, for him to enter a more active profession, and he chose civil engineering. He found employment with Samuel Barrett Cushing, a prominent engineer of Providence, and began what proved to be all but a half-century’s work devoted to engineering in its various fields and on two continents. In 1868 he was assistant engineer on the construction of the Hannibal & Naples Railroad in Illinois—now a part of the Wabash System—and a year later was engineer on the location and construction of the Hannibal & Missouri Railroad.
In 1871 he began his work in connection with the levees along the Mississippi River. He was chief engineer of the Sny Island Levee, fifty-one miles in length, and then became assistant to James B. Eads in the construction of the jetties at the South Pass mouth of the river. His health forced him to go north again in 1880.
During his convalescence he wrote his History of the Jetties at the Mouth of the Mississippi River (1880). Some construction work for the New York, West Shore & Buffalo Railroad Company was followed, in 1884, by Corthell’s association with Eads in the promotion of the Tehuantepec Ship Railway. In exploiting this railway he visited various cities of the United States and exhibited perfect working models of the railroad and a ship being placed in its cradle on the rails. By this time he had established himself as a consulting engineer and was variously engaged on the construction of railroads, bridges, and harbors all over the country.
He was engineer in charge of the design and construction of the substructure and foundation of the St. Louis Merchants’ Bridge over the Mississippi, and acted as special consultant in charge of the terminal work in Chicago for the Chicago, Madison & Northern Railroad. In 1889 he examined and submitted plans and a report on an improvement of the harbor at Tampico, Mexico, for the Mexican Central Railroad; later he was chief engineer for the construction of their jetties. In 1891 Corthell went to Europe to study engineering education as it was administered in the leading universities and technical schools there. This was in conjunction with his work as a trustee of the University of Chicago. He also examined European railroad terminals and harbors in order to fit himself better for solving problems in the United States and Mexico. He revisited Europe in 1897.
The results of his investigations were published in the Engineering Magazine and presented in a paper which he read before the Fiftieth Anniversary Meeting of the American Association for the Advancement of Science held in Boston in 1898. In 1900 he sailed for Buenos Aires where, for the Argentine minister of public works, he investigated and reported on many problems pertaining to commerce. A few years later he was engaged on important commercial works in Brazil, at Para, and in other South American cities. He maintained his consulting engineering office in New York City.
Corthell was representative for the Department of State of the United States at the International Engineering Congress in Brussels. It was he who suggested and then acted as chair man of the executive committee having charge of the International Engineering Congress held during the Columbian Exposition. He was active in advancing the interests of the national technical and scientific societies and his printed papers on engineering subjects fill many volumes.

Corthell had boundless enthusiasm and industry, and was generous not only with advice but with financial aid to younger members of his profession.
Corthell was married in 1870 to Emily Thcodate Davis of Providence, Rhode Island. She died in 1884, and in 1900 Corthell married Marie Kiichler of Berne, Switzerland.
