Sawdust and Mill Rubbish
Sawdust and Mill Rubbish.
A careful examination of the Ottawa River below the city of Ottawa was made by Mr. Mather. The burning of the sawdust and refuse in furnaces constructed for the purpose, is recommended by him. The cost of each furnace is estimated at a little over $100,000, and the annual cost of working at $42,147. Between Ottawa and Grenville every year 12 300,000 cubic feet of sawdust is deposited in the Ottawa, but in 143 soundings taken by Mr. Mather, sawdust was only brought up from the bottom in 26; in 117 soundings the matter was pure sand, gravel or clay, and in only 7 places was sawdust found in the navigable channel of the river, and navigation is in no way affected by it between Ottawa and Grenville.
