Mr. HENDERSON. I ask the pardon of the Senate for proposing one other amendment. I said that I would not do so. The Senfrom Iowa objected that the bottom lands of the river could not be crossed without trestle work, and that where that will be very high it will endanger the railroad interest. I now river may be in consequence of the building of ll propose to enable them to build iron submerged tubular bridges so as to enable them to go entirely beneath the river. I understand from competent engineers that such bridges can be constructed without any impediment to navigation; and I have the indorsement of them in my hands. of Mr. Linville, also of Mr. Thomas A. Scott, the VEEP of the Pennsylvania Central; J. Edgar Thom son, who is known to most Senators; the certi cate of Mr. Miller and of Mr. Herman J. Lomhaert, and also of Mr. W. W. Wright. who it will be remembered was the engineer in charge of the bridge building under GenlSherman . They all say that a submerged iron tubular bridge can be constructed so as not in the least to impede the navigation of this stream, and so constructed as to enable the railroads to carry on their business without any serious obstruction. If this can be done, why not let this commission certify the fact to us? If we can get rid of this trestle work, which the Senfrom Iowa thinks to be so very dangerous, and can go entirely beneath the surface of the water, let us do it. Sir, I am serious and in earnest about this thing. I do not wish to take up the time of the Senate, and I am not making frivolous motions. Iam making motions which I believe would subserve the very best interests of the country. provided this Senate would adopt them. I am satisfied that the future will demonstrate it. I know that these bridges will not stand there. I know that they are going to prove an obstruction of the river. When I say that. I simply mean to say that Congress will repeal the law and will leave these gentlemen without any substantial foundation, and they will be beaten in the courts of the country; I mean to say that it will turn out that these bridges are an obstruction to the navigation of the river, and I mean to say that Congress, in the just exercise of a proper discretion in regard to the very best commercial and navigation interests of this country, will not permit them to stand. Senators may so they know as much as I do uponthissubject. I’erhapstheydo. Ifeelsatis lied that no such bridge could be built upon any other great river in this country except the Mississippi river today by this Congress. am satisfied that no other river navigable as this is could be so bridged. No proposition to bridge any of the waters from Lake Superior to Niagara falls would receive the consent or support of this Senate today; and yet there is no river between those lakes possessing the importance that this does; it is not a river having on it the commerce that this has. The Senfrom Iowa is vastly mistaken when he supposes the railroad interests of this country are superior, so for as the business done is concerned.
