30th June, 1853.

GENTLEMEN,--I am directed to draw your attention to the accompanying advertisement from this Department, calling for Tenders for the improvement of a portion of the Channel of the River St. Lawrence,-a class of work in which you are stated to have had extensive experience.

I am, Gentlemen,
Your obedient servant,
T. A. BEGLY,
Secretary.
Messrs. Maillefert & Raasloff,
Sub-marine Engineers,
New York.
River St. Lawrence.

Notice is hereby given that Tenders addressed to the "Commissioners of Public Works" will be received at this Office until Thursday, the first day of September next, for the opening and permanently defining a navigable Channel throughout the whole of the Rapids of the St. Lawrence, from Prescott to Montreal; such Channel to be not less than 200 feet in width, to have at no place, at low summer water, a less clear depth than 12 feet, and in those Rapids subject to much swell, not less than 13 feet.

It is to be stated in the Tenders a bulk sum for the entire work necessary to open and permanently define a Channel, as above mentioned, and the period for its completion.

The test for the Channel, being so opened, to be the passing of as many vessels as the Commissioners of Public Works may consider necessary, each vessel to be so loaded as to draw ten feet water. The security for the performance of the work to be ample and bona fide. Conditions of payment and any other information may be known by applying at this Office.

Tenders to be endorsed "Tender for improving the Rapids of the Saint Lawrence."

By order,
THOMAS A. BEGLY,
Secretary. Department of Public Works, 29th June, 1853.
