Fish Story—A Monster.—Every oneJ Frcknows that the northern portion of this tjcl State abounds in little lakes, of from a I half to two or three miles in extent, and jprn that those lakes, from some cause or other, (CYC all boast of their curiosities. Some twen-maty or twenty-five miles north of this place, near Rochester, is a lake which the Indians, from a superstitious fear, have cliris-thcwiantf1tianod “Lake Martitoe,” or the Devil's c.° Lake. A singular story has lately beenrevived in regard to a monstrous animalnr-nde1 which its waters arc said to contain.Prngv*■»y _t-a-inn-! I*mrnL\va\Plt;lcfie-iicsr-imofiteoi-Some ten years ago, at the building of the Pottawattamie Mills, at the outlet of the Lake, the workmen are said to have observed, perhaps on more than one occasion, something which they took to be an animal of extraordinary dimensions, moving through the water with a rapid motion, and disturbing to an unusual degree the usual placidity of the Lake’s surface. Lately this wonder has been seen again, and by persons entitled to every credibility. It is represented as being fifty or sixty feet long, Of a dun or dusky color, and has a head somewhat resembling that of a horn-1 \ less ox, with sparkling eyes, of a yellow (v hue. One of the witnesses is said to have seen it raise its head a distance of three I1 or fouv feet above the water, and that where it disappeared its wake was not unlike that I { oi a large craft moving with celerity thro’ 11 the water.t£tl\ivfinOWOWoldJUSarsndt ofThe Indians, who neither fish nor bathe in the Lake, have some fearful traditions in regard to the monster, which they say has existed for the last three hundred years. The Lake is very deep, and in some portions of it, the bottom has never been found.
