Schuyler's Island, upon the shore of which we passed Tuesday night, is nearly in the latitude of Burlington, Vermont. The distance from Port Douglass on the west, to Burlington on the east side of Champlain, over an open expanse of water, is nine miles and three quarters. We breakfasted by starlight, and passed Ligonier's Point early in the day. One mile and a half east of it is the group of little islands called Four Brothers. The lake grew narrower as we rowed southward, until, after passing Port Henry Iron Works, and the high promontory of Crown Point, upon which are the ruins of the French Fort Frederic, built in 1731, it has a width of only two miles. At eight o'clock P. M. we dropped anchor under the banks of Ticonderoga, not far from the outlet of Lake George. It is four miles by road between the two lakes. The stream which connects them can be ascended from Champlain about two miles to the Iron Works, the remainder of the river being filled with rapids. A railroad now (1867) connects lakes George and Champlain, over which an easy portage can be made. The ruined walls of Fort Ticonderoga are near the railroad landing. A little south of this the lake grows so narrow as to resemble a river. At its southern end, twenty-four miles from Ticonderoga, is situated the town of Whitehall, where the Champlain and Hudson River Canal forms a junction with Lake Champlain. This long river-like termination of Champlain gave to the Indians the fancy of calling it Tisinondrosa -- "the tail of the lake;" which in mouths inexperienced with the savage tongue became corrupted into Ticonderoga. Wednesday broke upon us a glorious day. Proceeding three miles to Patterson's Landing, into the "tail of the lake," I left the Mayeta to explore on foot the shores of Lake George, promising Bodfish to join him at Whitehall when my work should be finished.

In the last chapter I gave, from seemingly good authority, the appellation of the narrow terminal water of the southern end of Lake Champlain, "the tail of the lake." Another authority, in describing Lake George, says: "The Indians named the lake, on account of the purity of its waters, Horicon, or 'silvery water;' they also called it Canderi-oit, or 'the tail of the lake,' on account of its connecting with Lake Champlain." Cooper, in his "Last of the Mohicans," says: "It occurred to me that the French name of the lake was too complicated, the American too commonplace, and the Indian too unpronounceable for either to be used familiarly in a work of fiction." So he called it Horicon.
