548 mil, connected with the fact that a large boat will require more proportioned dimen- sions in ,the Canal, we are not warranted in calculating the enlarged Canal as adap- ted to boats of more than 70 tons burtlien, or double the present capacity; and when the locks are doubled equal 4 times the pre- sent capacity with single locks. Is this calculation at all commensurate with the prospective magnitude of the trade to be ac- commodated? The Canal Committee in their report recommend such a Canal as will accommodate boats of 120 tons burthcn; and by a table given in their report, as also in the report of the Canal Commissioners, it appears that a Canal adapted to the most favorable navigation: of boats of 130 tons burtlien, requires 8 feet depth of water and 80 feet width {at surface. But the dimen- sions settledby the Canal Board will only be suflicient for about half this burtlien. NoW,iit is not pretended, such a Canal will not floatga larger boat, nor that a larger one could not be navigated: but it is settled by the rule of calculation referred to, that such "a size is necesssry, for the most economi- cal and convenient navigation. This is also corroborated by experience on the Erie Canal, when the average load exceeds the rule of calculation ‘Mlly about one sixth; and it is apparent the rule should not be ex- ceeded when applied to larger boats, if safe- ty, convenience, and economy in the navi- getion, is to be secured. In adopting a liberal plan for the boats in general use, we shall have the advantage of a navigation, that in seasons of great pres- rsure in business, an additional 20 or 30 tons may be taken in the boat that usually car- ii-ies 120 tons, a consideration of great im- yportance. i ‘ i A _ The Canal Commissioners consider it important, as will be seen in the quotation sfrom their report, that such dimensions should be settled as will meet the prospec- tive demands of the trade, and thereby avoid the necessity of furtlier enlargement: which is no doubt the correct view of the subject. The inhabitants of towns, villages, and ci. ‘ties on the Canal, will desire to make per- manent improvements on its banks ; which ‘will render further enlargement expensive, and a severe encroachment on the establish- ved business arrangements of the country; it will be less expensive to make all neces. sary enlargements at one, than at two dif- ferent times; and the work may be better done. ; When the Canal was commenced, its _success_ and ultimate productiveness,‘was, m_,the View ofa large portion of the citizens ‘of the state, highly robleinatical; and many believed it woul load the state with debt, only to be relieved by heavy taxation. But the problem has been solved by expe- rience, which now exhibits the most con. -elusive demonstration, and will leave us "wholly without excuse, if we fail tomeet the question, on the scale demanded, by the clearest evidence of its prospective mag- nitude and importance. , ' The Canal Commissioners, in their re- IPON. say, “that doubling the locks will not double the capacity of the Canal.” This is ‘°lWl0l1S. as no lack can be placed so conve- niently for the navigation as the one that lays directly on the! towing-path. Boats will enter and leave this more conveniently, and with less delay than they, can the 2d A 3d lock should never be thought of; -as the delay in passing a 3d set on the eafilieiitrisection would greatly embarrass the Iiavigaftion, if only one towing-path was used. 'The passing each other on one path; ,.,., ls AMER1°N.“” AND terially enhance the expense of navigation. Very little reflection is required to show, that the most economical navigation would. be that which required only. one _set of locks, which is a further consideration for acanal of liberal diineiisions, that the navi- gation may not be subjected to the delay incident to the necessary use of the 2(_l1s_et of locks, when it is practicable to avoio. it. To remedy this by a towing-path on the berme side, is considered by the _Canal Commissioners, in their report, ‘<15 1n_00m- ‘patiblc with thciaccommod ation of . business on its borders, as also the convenient navi- gation of the Canal itself: We are, there- fore, brought to a single towing-path and _a double set of locks, as affording the maxi- mum capacity of the canal. From the suggestion of the Canal Com- missioners and our own observation, We infer that the 2d set of locks would do about two-thirds the business of the 1st set: and if the capacity of the boat is doubled, we may estimate the entire capacity of the Canal when enlarged to 0' feet deep and 60 feet wide, in comparison with the present capacity as 10 to 3, or a fraction over 3 times. » By the report of the Canal Committee, it appears the business on the Canal has, ex- cepting a small fraction, been confined to our own state. In view of the increased facilities that will be afforded by the en- larged Canal, in cheapening transportation, the improvements that may confidently be expected in our agriculture, the extension of our mechanic and manufacturing opera- tions, and {the tributaries that will be crea- ted by new lateral Canals, can we entertain any reasonable doubt, the business of our ownstate will alone double in the. course of the next twelve or fifteen years '5 Since the completion of the Canal it has doubled in about eight years. If then the Canal is made 6 feet and 60, at the end bf fifteen years we shall have it fully occupied for single locks, by the business of our own state; and the only resort to provide for further increase of our own business would be in doubling the locks; and if no other trade was to be provided for, this subject might be considered a reasonable provision. But when we look beyond the limits of our own state, and traverse the extensive and fertile regions that will naturally seek this channel as the avenue of intercourse with the Atlantic ma~rket——a district just emerg- ing from a wilderness,..and filling up with an intelligent and enterprising population,-— can we doubt for a moment, that the capa- city of the canal should be at least as large as will accommodate boats of the capacity recommended by the Canal Committee, to wit: 120 tons burtlien. It is not necessary to enter on any contested ground, for there will be as much as we can accommodate by a Canal on the most liberal scale, that will seek this route in preference to any other, if we provide the means for its accommoda. tion. But if our means are inadequate, still a large share will press into the Canal, and toe must feel the delays and embarrasments it will unavoidably produce, in the enhanced price ,of transportation. \ If this project was one that might load the state with a heavy debt, that could only l1f3_pa1d by imposing a general tax on its citizens, then, however bright might be the prospects of its ultimate utility, to those im- irgediately interested in its navigation, there would be reason to proceed with greater circumspection in the degree to which the improvement should be carried. But on this point there is no further ‘ground to revenue will in a few years, (at most 4 or 5,') pay the difference between the cost of6 and 8 feet depth. It is believed by men fa- miliar with this work, that the difference between 6 and 8 feet depth and correspond- ing width will not be more than $4,000,000. But to provide most liberally, suppose it cost $5,000,000 more; it will not require the revenue on the present tolls, over and above its maintainance, more than 4 or 5 years, and then we shall have a navigation that may be considered good for the next 50 years. Is it wise to do less '3 We do not censure the Canal Board ; they have been compelled to make their decision without any expression of the wishes of their fellow-citizens on the subject; for un. til their decision was published, we were slumbering over this important matter. We have been informed that one of the consi- derations that influenced the Board was, that no public meeting of citizens or their ineiiiorial indicated the importance in which they viewed the project of enlargement. But, as before observed, the Board have left this subject with a tacit expression, that they hold it open for re-consideration in Oc- tober next. Let us then lose no time in ob- taining such an expression of opinion, by public meetings and memorials, as will leave the Board no ground to doubt, that to com- ply with the wishes of their fellow-citizens, as well as to meet the magnitude of the ob- ject, a Canal of'8 feet in depth, and from 70 to 80 feet in general width, is indispensable. While surrounded by pressing calls of business, we have briefly called your atten. tion to some of the considerations involved in this project, and we hope, fellow-citizens, you will take such measures aswill secure your own interest, and promote the honor and prosperity of the state. . Shall a work of eminent usefulness, deeply affecting the interest of the state, fail to receive that degree of perfection which is demanded by the clearest demon- strations of its importance’! It is ‘not for the benefit, or to please the ambition of an individual, who may control the destinies of millions, to gratify a love of splendid things ; but, on the simple principle of use- fulness, _in affording the means of easy‘ communication to market fora numerous people, it is a magnificent project, and pe- , culiarly demands the attention of a govern- ment that is formed for purposes of utility. The means of accomplishment are 5 fully provided in the work itself ; not the least prospect of embarrassing the state with tax to defray the cost, can be indulged. It is indeed the grand artery, through which cir- culates the elements of -our -prosperity. Shall it then be said, the people of the State of New-York have not the sagacity to ap- preciate the importance, or the enterprize to promote .a work so deeply afl‘ec,ting their interest, and which at the same time is of so easy an accomplishment? They have only to say the word, and the work is done. And what will be done’! Let every citizen who regards the interests or the honors of the state, read carefully the reports that have been referred to, and reflect on the im- portance of the project, and we feel assured that an emcient effort will be put forth to accomplish the work on a scale that will be commensurate with its importance, and, in point of utility, will render it an imperisha. ble monument of the wisdom and enterprise of a free people. ‘ ’ .
