These general features being noticed, mention of a few extraordinary rainfalls may be of interest. The most remarkable rain in one day occurred September 13, 1879, at Purneah, in Bengal, when thirty-five inches fell; about as much as Illinois gets in a year. At Nagina, thirty-two and four-tenth inches fell. Some extraordinary showers have been recorded in our own country, the most rapid being one and one-half inches in five minutes: the most rapid long one, ten inches in three hours; but no record of a day in anywise approaches the Bengal rain. A peculiar phenomenon of occasional occurrence in the Western States is that of “cloud-bursts,” or “water-spouts” as they are sometimes called, when immense masses of water fall in a few minutes. As the entire amount of moisture that can be held by the atmosphere at ordinary temperature would make but two inches of rain, it must follow that to produce such downpours as are here recorded, immense quantities of moisture from a wide area must be drawn in and condensed rapidly at a single point. Perhaps this is done by a reverse cyclonic movement, the atmosphere rapidly descending in a “spout,” instead of ascending. August 11, 1876, a tremendous downpour occurred at Fort Sully, Dakota: “and on the opposite side of the Missouri River, the water draining from a canon was reported to have moved out in a solid bank three feet deep and two hundred feet wide.” Two others of nearly equal violence occurred during the same month: one in Utah, and one in Kansas. “June 12, 1879, on Beaver Creek, ninety miles south of Deadwood, Dakota, there was a cloud-burst, which, without a gradual rise of water, in a few minutes covered the country and drowned eleven persons.” A cloud-burst in June, 1884, sent a torrent eight feet deep from the hillside into Jefferson, Montana, drowning several persons. Another one in June, 1885, destroyed a town in Mexico, drowning over one hundred and seventy of its eight hundred inhabitants. Cloud-bursts near Pittsburg, on the night of July 25, 1874, destroyed $500,000 worth of property, and drowned or crushed in the wrecks, one hundred and thirty-four persons. A cloud-burst in Arizona, August 6, 1881, changed the Hassayampa River from a dry ravine at sunset to a river a mile wide and from two to fifteen feet deep by 11 P.M.; by noon next day the river was again dry. Two days later a downpour at Central City, Colorado, suddenly left from four to six feet of water in the two principal streets. Snow is practically unknown over two-thirds of the land surface of the earth, and the damage done by it is confined largely to the inland regions of the temperate zone. And even then heavy snowfalls do no great injury unless followed by extremely cold wind. The blizzard laden with “icy sand” is fearful.
