about three-quarters of a mile above the upper pier, and at what was
formerly the Chute a Biondeau, is rather strong. These difficulties can
be easily overcome--the former by building an embankment from the pier
to Brophy's Island, the latter by removing some of the natural dam of
rock which once formed the "Chute."

The following are, in round numbers, the quantities of the principal
materials used:

Earth and puddle in embankment ...cub. yds. 148,500
Rock excavation, " 38,000
Riprap, " 6,600
Lock masonry " 14,200
Rubble masonry, " 16,600
Timber in cribs, lock bottoms and gates " 368,000
Wrought and cast iron, lb ................. 173,000
Stone filling cu yds ...................... 45,300
Concrete " 830

The total cost to date has been about $570,000, not including surveys,
engineering, etc.

The contractors for the canal, locks, etc., were Messrs. R. P. Cooke &
Co., of Brockville, Ont., who have built some large works in the States,
and who are now engaged building other extensive works for the Canadian
Government. The work here reflects great credit on their skill.

On the enlarged Grenville Canal, now approaching completion, there
are five locks, taking the place of the seven small ones built by the
Imperial Government. It will be open for navigation all through in the
