Rand, McNally & Co.'s illustrated guide to Niagra Falls ; with maps and diagrams . The Niagara is never frozen over, but it accumulates more icethan any other river in the world. From records kept, a rise in height of water of one foot at topof Falls will, by actual measurement, raise it 173^ feet below. The river, within four or five miles of the Falls, contains someof the best fishing grounds to be found anywhere. On the surface below the Falls, the current, when the water issmooth, runs on an average about 6 or 7 miles per hour. Sailorssay, about 30 or 40 feet deep, it runs at least 10 or 12 knots. Andthis is the reason, we think, why saw-logs and other bodies plung-ing over the Horseshoe Fall are not seen until they come up at theWhirlpool, a distance of 3 miles. There is a tradition that there is a periodical rise and fall inthe level of the Lakes, embracing a period of 14 years. In 1843, 1857 and 1871 the Niagara river was very low. March 29, 1843, a heavy gale from the west caused the highestwater ever known. The water rose 6 feet perpendicularly on theRapids.. Scde of Statute Miles, 0 5 Map of Niagara River.19 20 NIAGARA FALLS. On March 29, 1848, a strong east wind drove the water back intoLake Erie. The heavy ice was wedged in at the mouth of theriver. This jammed the water up, and soon the river was nearlydry. The rocks under the Rapids were bare, and people walkedand drove over them. The Falls, of course, shrank to a merenothing The next morning, the ice was forced out, and Niagararesumed its sway, but the sights and the experiences of that daywere novel ones. The average depth of the river from Lake Erie to the Falls isabout 20 feet. In some places it is over 2 miles wide. At thenarrowest point, near the Whirlpool, the current is above 40 milesper hour, and at the widest part, about 4 miles per hour. Between the Falls and the Whirlpool, the depth varies from 75to 200 feet, At the Whirlpool Rapids, it is estimated at 250feet; in the Whirlpool, at 400. But i
