A quart of water, evaporated to dryness, gave _thirty-one_ grains of a residuum. The same quantity of water, treated agreeably to the rule laid down by Westrumb, contained eighteen and a half inches of carbonic acid gas. The residuum, treated according to the rules given by Dr. Henry, in his system of Chemistry, gave the following result. Sulphate of Magnesia or Epsom Salts, 20 grains. Sulphate of Lime, . . . . . . . . . 3¾ " Muriate of Soda, . . . . . . . . . . 2½ " Muriate of Lime, . . . . . . . . . . ¾ " Carbonate of Iron, . . . . . . . . . 1¼ " Carbonate of Lime, . . . . . . . . . 2 " Loss, . . . . . . . . . . . . . . . ¾ " ——— 31 grains. To which must be added 18½ cubic inches of carbonic acid gas. “These waters,” says our author, “have acquired so great a reputation that immense quantities are sent away daily in barrels to perform long and expensive journeys by land to go and cure those who cannot come to them. The price of a barrel filled, and ready booted and spurred for its journey, is three dollars—and that is enough to last a regular and prudent toper four months.” _Letter VIII_ is dated “_Somerset, August 14_.” At 10 in the morning of this day, our traveller left the Springs in a hack, to join the mail coach at Bedford on its way to Somerset. “In an hour,” says Mr. P. “we were snugly ensconced in one of Mr. Reeside's well-appointed coaches, and rumbling over the stone turnpike on our way to the great west.” The road for eleven miles is, we are told, not very hilly. Afterwards the country rises gradually from plateau to plateau, for a {449} distance of fourteen miles, when you reach the summit of the Alleghany. Here is a large stone tavern, where the coach takes fresh horses. The country is now nearly level—but for the next six miles descends by alternate declivities and levels into “the broad valley which lies between the summits of the Alleghany Mountain and Laurel Hill,” the distance between which is about twenty miles. In this valley stands Somerset, which Mr. P. reached at half past 7 P. M. “having been eight hours and a half in travelling thirty-eight miles from Bedford.” _Letter IX_ is dated “_Pittsburg, August 16_.” At half past 3 A. M. on the 15th, the tourist took the coach from the east bound to the City of Furnaces—at 7 passed the summit of Laurel Hill—at 8 arrived at _Jones' Mills_, about one-third down the western declivity of the mountain, and breakfasted—at one reached Mount Pleasant, having passed through two mountain villages, Donegal and Madison—thence twenty miles to Stewartsville—thence thirteen farther to _Pittsburgium, longæ finis chartæque viæque,_
