First. Their heads were broad and extremely flat; the eyes protuberant, and the ears scarcely perceptible--being a small opening closed by a movable valve shaped like the scale of a salmon. Their mouths were very large, extending entirely across the cheeks, and bounded by a hard rim of bone, instead of the common lip. In appearance, therefore, the head did not look unlike an immense catfish head, except there were no fins about the jaws, and no feelers, as we call them. Second. Their necks were short, stout, and chubby, and they possessed the power of inflating them at will, and thus distending them to two or three times their ordinary size. Third. Their bodies were long, round, and flexible. When wet, they glistened in the sun like the back of an eel, and seemed to possess much greater buoyancy than those of common men. But the greatest wonder of all was a kind of loose membrane, that extended from beneath their shoulders all the way down their sides, and connected itself with the upper portion of their thighs. This loose skin resembled the wings of the common house bat, and when spread out, as it always did in the water, looked like the membrane lining of the legs and fore feet of the chipmunk. Fourth. The hands and feet were distinguished for much greater length of toe and finger; and their extremities grew together like the toes of a duck, forming a complete web betwixt all the fingers and toes. The Pol-i-wogs lived chiefly upon fish and oysters, of which there was once a great abundance in the lake. They were likewise cannibals, and ate their enemies without stint or compunction. A young Washoe girl was considered a feast, but a lake maiden was the _ne plus ultra_ of luxuries. The Washoes reciprocated the compliment, and fattened upon the blubber of the Pol-i-wogs. It is true that they were extremely difficult to capture, for, when hotly pursued, they plunged into the lake, and by expert swimming and extraordinary diving, they generally managed to effect their escape. Juan having exhausted his budget concerning the Pol-i-wogs, I requested him to give us as minute a description of the Lake Mermaids. This he declined for the present to do, alleging as an excuse that we would first attempt to capture, or at least to see one for ourselves, and if our hunt was unsuccessful, he would then gratify our curiosity.
