The navigation from lake Erie to Albany, can be completed in ten days with perfect safety on the canal; and from Albany to New-York, there is the best sloop navigation in the world. From Buffalo to Albany, a ton of commodities could be conveyed on the intended canal, for three dollars, and from Albany to New-York, according to the present prices of sloop transportation, for $2.80, and the return cargoes would be the same. We have not sufficient data upon which to predicate very accurate estimates with regard to Montreal and New Orleans; but we have no hesitation in saying, that the descending conveyance to the former, would be four times the expense, and to the latter, at least ten times, and that the cost of the ascending transportation would be greatly enhanced.

It has been stated by several of the most respectable citizens of Ohio, that the present expense of transportation by water from the city of New-York to Sandusky, including the carrying places, is $4.50 per hundred, and allowing it to cost two dollars per hundred for transportation to Clinton, the geographical centre of the state, the whole expense would be $6.50, which is only fifty cents more than the transportation from Philadelphia to Pittsburgh, and at least $2.50 less than the transportation by land and water from these places, and that, in their opinion, New-York is the natural emporium of that trade, and that the whole commercial intercourse of the western country north of the Ohio, will be secured to her by the contemplated canal.

In addition to this, it may be stated that the St Lawrence is generally locked up by ice seven months in the year, during which time produce lies a dead weight on the hands of the owner; that the navigation from New-York to the ocean, is at all times easy, and seldom obstructed by ice, and that the passage from the Balize to New-Orleans is tedious; that perhaps one out of five of the western boatmen who descend the Mississippi, become victims to disease; and that many important articles of western production are injured or destroyed by the climate. New-York is, therefore, placed in a happy medium between the insalubrious heat of the Mississippi, and the severe cold of the St Lawrence. She has also pre-eminent advantages, as to the goodness and extensiveness of her market. All the productions of the soil, and the fabrics of art, can command an adequate price, and foreign commodities can generally be procured at a lower rate. The trade of the Mississippi is already in the hands of her merchants, and although accidental and transient causes may have concurred to give Montreal an ascendency in some points, yet the superiority of New-York is founded in nature, and if improved by the wisdom of government, must always soar above competition.

Granting, however, that the rivals of New-York will command a considerable portion of the western trade, yet it must be obvious, from these united considerations, that she will engross more than sufficient to render her the greatest commercial city in the world. The whole line of canal will exhibit boats loaded with flour, pork, beef, pot and pearl ashes, flaxseed, wheat, barley, corn, hemp, wool, flax, iron, lead, copper, salt, gypsum, coal, tar, fur, peltry, ginseng, bees-wax, cheese, butter, lard, staves, lumber, and the other valuable productions of our country; and also, with merchandise from all parts of the world. Great manufacturing establishments will spring up; agriculture will establish its granaries, and commerce its warehouses in all directions. Villages, towns, and cities, will line the banks of the canal, and the shore of the Hudson from Erie to New-York. “The wilderness and the solitary place will become glad, and the desert will rejoice and blossom as the rose.”

While it is universally admitted that there ought to be a water communication between the great lakes and the tide waters of the Hudson, a contrariety of opinion (greatly to be deplored, as tending to injure the whole undertaking) has arisen with respect to the route that ought to be adopted. It is contended on the one side, that the canal should commence in the vicinity of the outlet of lake Erie, and be carried in the most eligible direction across the country to the head waters of the Mohawk river at Rome: from whence it should be continued along the valley of the Mohawk to the Hudson. It is, on the other side, insisted, that it should be cut around the cataract of Niagara; that lake Ontario should be navigated to the mouth of the Oswego river; that the navigation of that river, and Wood creek, should be improved and pursued until the junction of the latter with the Mohawk at Rome. As to the expediency of a canal from Rome to the Hudson, there is no discrepance of opinion: the route from Rome to the great Lakes constitutes the subject of controversy.

If both plans were presented to the legislature, as worthy of patronage, and if the advocates of the route by lake Ontario did not insist that their schemes should be exclusive, and of course, that its adoption should prove fatal to the other project, this question would not exhibit so serious an aspect. If two roads are made, that which is most accommodating will be preferred; but if only one is established, whether convenient or inconvenient to individuals, beneficial or detrimental to the public, it must necessarily be used. We are so fully persuaded of the superiority of the Erie canal, that although we should greatly regret so useless an expenditure of public money as making a canal round the cataract of Niagara, yet we should not apprehend any danger from the competition of Montreal, if the former were established.

The invincible argument in favor of the Erie canal is, that it would diffuse the blessings of internal navigation over the most fertile and populous parts of the state, and supply the whole community with salt, gypsum, and in all probability coal. Whereas the Ontario route would accommodate but an inconsiderable part of our territory, and instead of being a great highway, leading directly to the object, it would be a circuitous by-road, inconvenient in all essential respects.

The most serious objection against the Ontario route, is, that it will inevitably enrich the territory of a foreign power, at the expense of the United States. If a canal is cut around the falls of Niagara, and no countervailing nor counteracting system is adopted in relation to lake Erie, the commerce of the west is lost to us for ever. When a vessel once descends into Ontario, she will pursue the course ordained by Nature. The British Government are fully aware of this, and are now taking the most active measures to facilitate the passage down the St Lawrence.

It is not to be concealed, that a great portion of the productions of our western country are now transported to Montreal, even with all the inconveniences attending the navigation down the Seneca and Oswego rivers; but if this route is improved in the way proposed, and the other not opened, the consequences will be most prejudicial. A barrel of flour is now transported from Cayuga lake to Montreal for $1.50, and it cannot be conveyed to Albany for less than $2.50. This simple fact speaks a volume of admonitory instruction. But taking it for granted, that the Ontario route will bring the commerce of the west to New-York, yet the other ought to be preferred, on account of the superior facilities it affords.

In the first place, it is nearer. The distance from Buffalo to Rome, is less than 200 miles in the course of the intended canal: by lake Ontario and Oswego, it is 232.
