In the presence of this great assemblage, and of the chosen representatives of the people of these two great cities, of the Governor of the State of New York and of the President of the United States, the pleasing duty devolves upon me, as the official agent of the Board of Trustees of the New York and Brooklyn Bridge, to announce formally to the chief magistrates of these two municipalities that this Bridge is now ready to be opened for public use, and is subject in its control and management only to such restrictions as the people, to whom it belongs, may choose to impose upon themselves. If I were at liberty to consult my own wishes I should not attempt to occupy your attention any further. I am not here as the spokesman of my associates in the Board of Bridge Trustees. They are well content to let this great structure speak for them, and to speak more fittingly and more eloquently yet for the skillful, faithful and daring men who have given so many years of their lives--and in several instances even their lives--to the end that the natural barrier to the union, growth and greatness of this great commercial centre should be removed, and that a vast scientific conception should be matched in the skill, and courage, and endurance upon which it depended for its realization. With one name, in an especial sense, this Bridge will always be associated--that of Roebling. At the outset of this enterprise we were so fortunate as to be able to secure the services of the late John A. Roebling, who had built the chief suspension bridges in this country, and who had just then completed the largest suspension bridge ever constructed up to that time. His name and achievements were of invaluable service to this enterprise in its infancy. They secured for it a confidence not otherwise obtainable. He entered promptly and with more than professional zeal into the work of erecting a bridge over the East River. As is universally known, while testing and perfecting his surveys his foot was crushed between the planks of one of our piers; lockjaw supervened, and the man who designed this Bridge lost his life in its service. The main designs were, however, completed by the elder Roebling before he met his sad and untimely death. He was succeeded at once by his son, Colonel Washington A. Roebling, who had for years before shared in his father's professional confidences and labors. Here the son did not succeed the father by inheritance merely. The elder Roebling, according to his own statements, would not have undertaken the conduct of this work at his age--and he was independent of mere professional gain--if it were not for the fact, as he frequently stated, that he had a son who was entirely capable of building this Bridge. Indeed, the elder Roebling advised that the son, who was destined to carry on and complete the work, should be placed in chief authority at the beginning. The turning point--as determining the feasibility of this enterprise--was reached down in the earth, and under the bed of the East River. During the anxious days and nights while work was going on within the caissons, Colonel Roebling seemed to be always on hand, at the head of his men, to direct their efforts, and to guard against a mishap or a mistake which, at this stage of the work, might have proved to be disastrous. The foundations of the towers were successfully laid, and the problem of the feasibility of the Bridge was solved. Colonel Roebling contracted the mysterious disease in the caissons which had proved fatal to several of the workmen in our employ. For many long and weary years this man, who entered our service young and full of life, and hope, and daring, has been an invalid and confined to his home. He has never seen this structure as it now stands, save from a distance. But the disease, which has shattered his nervous system for the time, seemed not to have enfeebled his mind. It appeared even to quicken his intellect. His physical infirmities shut him out, so to speak, from the world, and left him dependent largely on the society of his family, but it gave him for a companion day and night this darling child of his genius--every step of whose progress he has directed and watched over with paternal solicitude. Colonel Roebling may never walk across this Bridge, as so many of his fellow-men have done to-day, but while this structure stands he will make all who use it his debtor. His infirmities are still such that he who would be the centre of interest on this occasion, and even in this greatly distinguished company, is conspicuous by his absence. This enterprise was only less fortunate in securing an executive head than in obtaining scientific direction. For sixteen years together the late Hon. Henry C.
