PITTSBURG, October 2. Practical Demonstration.-On Wednesday evening, before sunset, a sinall keel boat, with seventy barrels of salt, towed by one small horse, arrived at Alleghenytown, from Freeport, which place she left that morning. To have conveyed this salt by land, would have requir cd six wagons, with five horses and a driver each, and one day and a half travelling.

Thus, on the Canal, one horse and two men have performed the work, in one day, which, by a turnpike road, would have employed thirty horses and six men for one day and a half each.

LUMBER.--About eight million feet of lumber, at the lowest estimate, will be consumed the present season in this borough and vicinity, which has made it a scarce article, and advanced its price two-fold. All the sawmills in the neighbourhood have been kept in full gear, but the quantity they supply has not been adequate to the demand, large quantities having been brought from the Susquehanna and Philadelphia.

Large tracts of well-timbered land abound in the Catawissa Valley, along the Mahanoy, and in fact throughout almost every portion of this country, through which streams are winding, on whose courses numerous sawmills can be erected at a trifling expense, and would abundantly reward those who feel disposed to embark in such undertakings.

In some of these vallies the soil is of an excellent

quality, and could be cultivated to great advantage. Miners Journal.

CANAL COMMISSIONERS' OFFICE,
Philadelphia, Feb. 3, 1826.

SIR,-I have the honor herewith to transmit to your Excellency, a report of the Commissioners, together with the field notes, drafts and maps, therein referred

to.

With the highest respect,
Sir, your most obd't serv't,
JOHN SERGEANT, Pres't.

His Excellency, J, ANDW. SHULZE,
Governor of Pennsylvania.

The Canal Commissioners of Pennsylvania, in obedience to the 8th section of the act of 7th April last, requiring them to present "a plain and comprehensive report of all their proceedings," respectfully submit the following statement:

The attention of the board during the past season, has been directed exclusively to those routes, which were supposed to admit of a navigable communication between the Allegheny and Susquehanna rivers, across the great ridge which divides the eastern and western waters of the state. Four such routes have been accurately levelled and surveyed--and it remains only for the board to detail the results.

what point the waters of that stream could be used for him to propose sinking his summit, by means of a tunnel, and deep cut 142 feet below the top of the ridge. At this level, it was ascertained that a large quantity of water could be procured from the branches of Toby, and other streams in the vicinity. These streams were carefully measured, and the number of cubic feet, which they are estimated to furnish per day, is as follows:

[blocks in formation]

It is believed that reliance may be placed upon the method pursued in these measurements; but Mr. Wil son has justly remarked, that in the midst of a wilderness, and with no other tools than axes, it was impossible to construct the dams employed, in such a manner as to be tight, and that the flow of water on this account, is probably much undervalued. Two streamsMill creek and Otter run, were not guaged, and are therefore omitted in the foregoing list, although Mr. Wilson thinks they would afford a considerable supply.

It has been stated, that in order to obtain this supply of water, the summit level must be depressed, and a tunnel constructed. Mr. Wilson ascertained that the length of the tunnel would be 482 perches, supposing the open canal continued at each end, until it reached the depth of 40 feet. The soil was found to be a soft clay-slate, and sand stone, very favorable for such a work, as it is easy of excavation, and wouli prevent the necessity of arching.

down to the mouth of the Juniata.

The examination of the most northern route, was entrusted to William Wilson, Esq. of Lycoming county, who left Williamsport with his party, on the 4th July. According to the instructions of the board, he proceed ed immediately to the dividing ridge, in order to search for a pass by which a cana! might be conducted with a sufficient supply of water upon its summit level. Such a pass was supposed to exist at Flag Swamp, a marsh situated between the north end of Boone's mountain, and the ridge whish separates Kersey's run, (a tributary of Bennett's branch of the Sinnemahoning,) from Little Toby's creek, This marsh occupies the centre Having finished these operations upon the summit, ground so exactly, as to discharge part of its waters in- the routes to the Susquehanna, by the Sinnemahoning to each of these streams, and had therefore been repre- and West branch, and to the Allegheny by Toby's sented to the board as an eligible route for a canal. creek and Clarion river, were next to be attended to. Accordingly, Mr. Wilson gave his earliest attention to The season was so far advanced, that the first of these this spot. But after levelling from it to the neighbor-only, could be examined. But this was carefully done ing streams, in various directions, he found it did not admit of an adequate supply of water. Compelled to abandon this route, Mr. Wilson extended his levels towards the head waters of the Driftwood branch of Sinnemahoning, and after many fruitless researches, was at length so fortunate as to find a pass 140 feet lower than Flag Swamp, and much nearer to the feeding streams, which alone can supply any summit in that quarter. Subsequent examinations render it extremely probable, that this pass is in fact the lowest in that part An impression having very generally prevailed, that of the country. It is about 400 feet lower than the divi-a practicable pass for a canal might be found, at the ding ridge to the southeast, which separates the branch-head waters of the West branch of Susquehanna, John es of Big and Little Toby, and to the north, the ridges rise far above it, uniting themselves with the high table land in which the Big Toby, the Allegheny, Gennessee, Cowanesque, Pine Creek, and Sinnemahoning, have their sources. Its height above the mouth of Juniata, is 1400 feet, and above Pittsburg, 967 feet. After discovering this pass, Mr. Wilson proceeded with his levels to Big Toby, in order to determine at VOL. IV. 37

The accompanying map and profiles will give the result of this survey. The draft of Toby's creek, and Clarion river, and of the Allegheny river to the mouth of Kiskeminetas was copied from the state map, and the board cannot therefore be responsible for its correctness. The entire descent to Pittsburg was ascer tained from a connexion of the levels, taken by the different parties, under the direction of the board.

Mitchell, Esq. of Centre county, was engaged to examine in that direction. He left Bellefonte with his party on the 2d of August, and after passing some days in exploring the country, which divides the waters of Big Mahoning and the Susquehanna, established his first level bench, at a part of the ridge called in the map "the Clover Patch." From this point he directed his levels to the river, which he struck about a mile and a half below the mouth of Chest creek, and at a depres

sion of 794 feet below the suinmit of the ridge. He must be depressed;- and it was ssccriained that this then took his course up the river to the Cherry Tree," could be done tv the depth of 220.34 fret below the which stands immediately below the mouth of Cushing top of the ridge, by a tunnel 367 percles in length.
