[Illustration: DETAILS OF THE OTTAWA RIVER DAM, AT CARILLON.]

The construction of the dam and slide was ably superintended by Horace
Merrill, Esq., late superintendent of the "Ottawa River Improvements,"
who has built nearly all the slides and other works on the Ottawa to
facilitate the passage of its immense timber productions.

The contractors were the well known firm of F.B. McNamee & Co., of
Montreal, and the successful completion of the work was in a large
degree due to the energy displayed by the working member of that
firm--Mr. A.G. Nish, formerly engineer of the Montreal harbor.
