He is often pleased to note the progress in American enterprise, and among other events that has come under his own observation, relates the following: In the year 1839, he commenced his first railroad service upon the foundation of a bridge that was then being erected across the Connecticut river at Springfield, Mass., of 1260 feet in length. It was regarded as a very difficult undertaking, as the bed of the river was composed mostly of quicksand, and a rise of 25-1/2 feet in the river had to be provided for, and floating ice, its full width, fifteen inches in thickness. Maj. George W. Whistler, the first of his profession, was chief engineer of the work, and he had as advisers Maj. McNeal, Capt. Swift, and other eminent engineers. The work was about three years under construction, at a cost of over $131,000, and every effort was made to keep its cost at the lowest possible point, at the same time making certain the stability of the structure. Within nine years from the time of its completion, a similar structure, in every particular, was to be constructed across the same river, at Hartford, twenty-six miles below. Its length varied but a few feet, although it covered more water, and its foundations and other contingencies were quite as difficult and unfavorable. Mr. Stone concluded a contract for its construction for the firm of Stone & Harris, complete, for the sum of $77,000, and to have it ready for the cars in twenty months. The work was executed in accordance with the terms of the contract, and has not only proved as substantial as that at Springfield, but in many particulars, more so. It was the pride of Mr. Stone for many reasons, (among others, that it was stated by many that it could not be done for this sum of money,) to personally superintend this work himself, and to put in practice some of his own inventions, the most important of which was the cutting off the foundation piles with a saw arranged on a scow, propelled by a steam engine, and the sinking of the piers below water by means of screws. The result proved to be satisfactory, and as favorable, in a financial point of view, as he estimated. It will be noticed that the bridge structure, complete, at Hartford, cost $54,000 less than that at Springfield, of like character.
