A. P. J.—The Yellowstone River flows in a northerly direction out of Yellowstone Lake, and after a course of about 1300 miles, during which it descends about 7000 feet, it reaches the Missouri. The lake is one of the most beautiful sheets of water in the world, twenty-two miles in length, and from twelve to fifteen in breadth. Its elevation above the level of the sea is 7788 feet, and its greatest depth is 300 feet. Only four other lakes are known to have a greater elevation—lakes Titicaca and Uros, in Peru and Bolivia, which are respectively 12,874 and 12,359 feet above the level of the sea, and lakes Manasarowar and Rakas-Tal, in Tibet, which lie at the great height of 15,000 feet. The Upper and Lower Falls of the Yellowstone are wonderfully beautiful. They are not more than a quarter of a mile apart. Before reaching the first fall the river flows through a grassy valley with a calm, steady current, until it plunges over a ledge 140 feet in height. The second fall is more than 350 feet high. Over this precipice the river plunges in snow-white foam and spray. From the foot of the falls rises a dense and heavy mist, and no one can approach within several hundred yards without being drenched to the skin. On the west side the wall of rock is covered to the height of about 300 feet with a dense carpet of mosses, grasses, and other vegetation, of the most vivid green. There is nowhere in the world a more beautiful scene than that which is presented by this remarkable fall, although Niagara is more impressive on account of the volume of water which pours over the precipice.
Mary B.—Among the most celebrated poems of Robert Burns are "Tam o' Shanter" (about which an article was printed in the Post-office Box in No. 56), "The Cotter's Saturday Night," "To a Mouse," "Highland Mary," "John Anderson," "To a Mountain Daisy," "The Twa Dogs," "The Banks o' Doon," "Mary Morison," "Bruce's Address," "John Barleycorn," and "For a' That, and a' That." The best piece for speaking is "Bruce's Address," which can be found in almost every collection of poetry.
