Working on (he basis of the Italian one, he has made such improvements that in recent experiments it was found possible at the first shot to hit a boat three miles out at sea. The Electric Tight.—The achievements of science will speedily make the electric light one of the grandest and most useful ad .items to the many useful inventions of mankind, The chief cities of the universe will soon be lighted in dark nights as in noon day, and ocean steamers will flash from their mast heads such ligh sas will make collisions at sea easily avoidable. —Correspondent York 1/erald, Niagara Falls.—The amount of water passing over Niagara Falls has been estimated at 100,000,000 tons per hour, and its perpendicular descent maybe taken at 120 feet, without considering the rapids, which represent a further fall of 150 feet. The force represented by the principal fall alone amounts to 16,800,000 horse power, an amount which If it had to be j produced by steam would necessitate an expenditure of not less than 266,000,000 tons of coal per annum, taking the consumption of coal at four pounds per horse power. In other words, all the coal raised throughout the world harely suffices to produce the amount of power that annually runs to waste at this wonderful fall.
