miles, and from thence, passing the mines of Charcas, Zaccatecas, and Potosi, to the city of Mexico, is three hundred and seventy-five miles; in all, one thousand five hundred and fifty miles from Santa Fé to the city of Mexico. From New Orleans to the city of Mexico is about one thousand nine hundred and fifty miles; the roads after setting out from the Red river, near Natchitoches, keeping generally parallel with the coast, and about two hundred miles from it, till it enters the city of Mexico. The _Illinois_ is a fine river, clear, gentle, and without rapids; insomuch that it is navigable for batteaux to its source. From thence is a portage of two miles only to the Chicago, which affords a batteau navigation of sixteen miles to its entrance into lake Michigan. The Illinois, about ten miles above its mouth, is three hundred yards wide. The _Kaskaskia_ is one hundred yards wide at its entrance into the Mississippi, and preserves that breadth to the Buffalo plains, seventy miles above. So far, also, it is navigable for loaded batteaux, and perhaps much further. It is not rapid. The _Ohio_ is the most beautiful river on earth. Its current gentle, waters clear, and bosom smooth and unbroken by rocks and rapids, a single instance only excepted. It is one-quarter of a mile wide at Fort Pitt, five hundred yards at the mouth of the Great Kanhaway, one mile and twenty-five poles at Louisville, one-quarter of a mile on the rapids three or four miles below Louisville, half a mile where the low country begins, which is twenty miles above Green river, a mile and a quarter at the receipt of the Tennessee, and a mile wide at the mouth. Its length, as measured according to its meanders by Captain Hutchins, is as follows:-- From Fort Pitt To Log's Town 18½ Big Beaver Creek 10¾ Little Beaver Creek 13½ Yellow Creek 11¾ Two Creeks 21¾ Long Reach 53¾ End Long Reach 16½ Muskingum 25½ Little Kanhaway 12¼ Hockhocking 16 Great Kanhaway 82½ Guiandot 43¾ Sandy Creek 14½ Sioto 48¼ Little Miami 126¼ Licking Creek 8 Great Miami 26¾ Big Bones 32½ Kentucky 44¼ Rapids 77¼ Low Country 155¾ Buffalo River 64½ Wabash 97¼ Big Cave 42¾ Shawanee River 52½ Cherokee River 13 Massac 11 Mississippi 46 ----- 1188
