Mr. Macon (Speaker) opposed the rising of the committee, because it was leaving the business exactly where it stood, unless it was meant to recommit it to a select committee for modification. But as he was determined to vote against it in any and every shape, he was prepared to decide now. As to the mode he had taken to come at his object, he should only say it was a fair one, and such as had been the uniform practice of the House since he had a seat in it.

The gentlemen in favor of this dam or causeway, say it will do no harm; but where is the demonstration? On the other side, serious apprehensions are entertained of its injurious effects upon the United States navy yard in the Eastern branch, and its causing obstructions in the harbor of Alexandria. He would assure the committee he was ready to promote the welfare of any of the citizens; but it must in justice be done, without injuring any other portion whatever.

At the last session, an application was made for a permanent bridge across the Potomac, with a draw for the passage of vessels; the petitioner urged the general utility of the measure to all persons travelling North or South, but particularly the vast benefit accruing to the inhabitants of the district, by affording a solid and secure means of intercourse between its several parts. This measure was opposed by the present petitioners, on the ground of the compact between Maryland and Virginia securing the right of free navigation to the river, and also alleging that their navigation to Georgetown would be impeded. The argument which they applied then, now applies against them, and it ought, in the minds of the same legislators, to apply with equal success.

Mr. Findlay was rather in favor of the bill, believing the mode proposed would be successful in deepening the channel, which would certainly improve the navigation to and from Georgetown, and in that object the citizens of some of the western counties of Pennsylvania were materially interested; several of their boatable creeks nearly interlocking with those of the Potomac. He would, however, agree to the committee rising, with a view to postpone the bill, until gentlemen acquired the information they asked for.

Mr. Goddard hoped the committee would rise, and the subject be postponed until sufficient light was obtained to guide their votes to a proper decision. He also hoped that no member might be considered as the friend or the foe of the present bill, until he became such by an examination into its merits or demerits. He narrated the course the business had taken since its introduction into this House, and inferred that the same deliberate mode ought to be pursued to the end. Whether the measure was good or evil could only be determined in that way, and gentlemen ought not to object to doing positive good, unless it was demonstrated that positive evil would result to counterbalance the good that was intended. He conceived the members ought to inquire for themselves on this point, and legislate accordingly. He would on all occasions endeavor to promote the interests of the district; and as it had no immediate representative on the floor, he considered every representative bound to serve them, while the seat of Government remained among them.

Mr. G. W. Campbell would not declare whether he should vote for the final passage of the bill or not. But he was disposed to take notice of the applications made from time to time by the inhabitants of the district; whether to redress grievances, or procure benefits. But he by no means approved of the principles of legislation without representation. He regretted that they were placed in this unfortunate situation; but he should decide on the present question according to its merits; and if it was found to be of great consequence to the petitioners, and not likely to work an injury to others, he presumed the bill would finally pass. But he wished the committee to rise, in order to give further time to obtain information. It had been alleged that the friends of the measure ought to demonstrate that the erection of a causeway would do no injury to any one. This was not a fair position; it was requiring them to prove a negative. The burden of proof should lie on those who oppose the bill, and it was for them to demonstrate that injury would result. The gentleman from Virginia (Mr. J. Randolph) has stated that the boats from the western country have a choice of passing by the western or eastern channel to the market below Georgetown, and this, it is presumed, he means they should be still entitled to under the compact between Maryland and Virginia. Let us hear from those persons also, and then ascertain whether they have any objection to the project on that account. This was also an argument in favor of the rising of the committee, and perhaps it may be added, that a little delay will enable the House so to modify the bill as to render it less exceptionable than at present.

Mr. Southard had not considered this subject of much consequence in the outset, but he found that its importance increased as it toiled along. He thought this morning it would have occupied but a short portion of their time; in that he found himself deceived; and he believed he was not singular in these opinions. He suspected many other members were in the same predicament. He therefore would vote for the committee’s rising. That navigable waters are considered as highways, is a matter of great notoriety; but he did not know that to deepen a channel, by contracting its surface, was considered as obstructing the free navigation of a river, nor could he conceive that the body of sediment meant to be removed, would descend en masse and deposit itself at the confluence of the next stream it met. On the contrary, he imagined it would be separated by the force of the current giving it action into millions of particles, some of which would settle promiscuously on either side, while a part would ultimately be deposited in the ocean.

The committee hereupon rose and reported progress, and asked leave to sit again. On the question, Shall the committee have leave to sit again?

Mr. J. Randolph requested that the act of cession by Virginia might be read, by which it would clearly appear that she had not ceded, or intended to cede to the United States any right acquired under her compact with Maryland. [The act was read.]

It is plain from the preamble, said Mr. R., that the intention of the State was to make a cession above the tide water; that the expected seat of Government would be fixed in some place contiguous to the limits of Maryland and Pennsylvania. It is not contended that the United States were bound to select any particular spot. This circumstance is mentioned only to show what was contemplated at the time by the Legislature of Virginia. Her act of cession was more broad. It extended to any tract of country not exceeding ten miles square, “to be located within the limits of the State.” Over this she had relinquished to Congress her jurisdiction as well of soil as of persons. But her limits did not extend beyond high water mark on the western bank of the Potomac. Her right of highway on the river was a natural right acknowledged and secured by convention with Maryland. Her civil jurisdiction over its waters was a conventional right, entirely derived from compact with that State, was a jurisdiction not within her limits, and which the words of the act just read could not embrace or convey.
