Again they were on their way, slowly drifting down the great river. They passed the mouth of the Illinois, and glided beneath that line of rocks on the eastern side, cut into fantastic forms by the elements, and marked as "The Ruined Castles" on some of the early French maps. Presently they beheld a sight which reminded them that the Devil was still lord paramount of this wilderness. On the flat face of a high rock, were painted in red, black, and green a pair of monsters,--each "as large as a calf, with horns like a deer, red eyes, a beard like a tiger, and a frightful expression of countenance. The face is something like that of a man, the body covered with scales; and the tail so long that it passes entirely round the body, over the head and between the legs, ending like that of a fish." Such is the account which the worthy Jesuit gives of these _manitous_, or Indian gods. [Footnote: The rock where these figures were painted is immediately above the city of Alton. The tradition of their existence remains, though they are entirely effaced by time. In 1867, when I passed the place, a part of the rock had been quarried away, and, instead of Marquette's monsters, it bore a huge advertisement of "Plantation Bitters." Some years ago, certain persons, with more zeal than knowledge, proposed to restore the figures, after conceptions of their own; but the idea was abandoned. Marquette made a drawing of the two monsters, but it is lost. I have, however, a fac-simile of a map made a few years later by order of the Intendant Duchesneau; which is decorated with the portrait of one of them, answering to Marquette's description, and probably copied from his drawing. St. Cosme, who saw them in 1699, says that they were even then almost effaced. Douay and Joutel also speak of them; the former, bitterly hostile to his Jesuit contemporaries, charging Marquette with exaggeration in his account of them. Joutel could see nothing terrifying in their appearance; but he says that his Indians made sacrifices to them as they passed.] He confesses that at first they frightened him; and his imagination and that of his credulous companions were so wrought upon by these unhallowed efforts of Indian art, that they continued for a long time to talk of them as they plied their paddles. They were thus engaged, when they were suddenly aroused by a real danger. A torrent of yellow mud rushed furiously athwart the calm blue current of the Mississippi; boiling and surging, and sweeping in its course logs, branches, and uprooted trees. They had reached the mouth of the Missouri, where that savage river, descending from its mad career through a vast unknown of barbarism, poured its turbid floods into the bosom of its gentler sister. Their light canoes whirled on the miry vortex like dry leaves on an angry brook. "I never," writes Marquette, "saw any thing more terrific;" but they escaped with their fright, and held their way down the turbulent and swollen
