The Lake 120,000 Survey Board estimates the average flow to be 265,000 feet persecond. To develop the power would therefore require ll-265thsor a little more than four per cent, of the total flow, an amountscarcely perceptible at the Falls. This estimate is based on theassumed diversion of all the water that the tunnel will amount taken at first will be much smaller. The whole amountwould operate 240 mills of 500 horse-power each.— The Satisfactory Way. The execution of this little bookwas entirely turned over to The Matthews-Northrup Co., ofBuffalo, N. Y. They furnished everything for it except the readingmatter. The result is submitted as a good example of the wisdomof having work of this kind done as a whole by a firm which takesall the responsibility and guarantees satisfaction, in every particular. Thorough specialists in railroad work. The Matthews-NorthrupCo. stand equally high in every other branch. They furnish thebest value for the money in every kind of engraving, printing,or binding. You will find their imprint everywhere. They wouldlike to have you ask any of their customers whether it is not truethat it pays to get work done at a Complete Art-Printing Works. Tonawanda, on the Niagara River, between Buffalo andNiagara Falls, is noted the world over as being, with possiblyone or two exceptions, the largest lumber port in the UnitedStates, more lumber being handled th
