expect nothing better from the most skillful architect. The length of the structure is greater or less, according to the size of the stream which they wish to restrain. Dams of this kind a fifth of a mile long are sometimes found. But, if the river swell more than is safe, they break open some part of the structure, and let through as much water as seems sufficient. As the forests abound in wild beasts, so the rivers teem with fish. There is one in the lake of the Iroquois,[67] which is not mentioned by early authors. It is called by the natives "Causar," and is eight feet long, sometimes ten. It is as thick as the human thigh; it is dun-colored, approaching white; it bristles all over with scales, so hard and so firmly set together that they turn the edge of a knife or the point of a spear. The head is large, and protected by an exceedingly hard skull, like a helmet. Hence, the name of "armored fish" has been given it by the French. It carries on perpetual war with, and feeds upon, other fishes. For a weapon it carries an immense beak, of the length of a man's arm and furnished with a double row of teeth. With this hunting-spear it not only devours other fishes, but also, whenever it wishes to vary its diet, deceives and ensnares birds. For this latter purpose it hides itself among the sedge; it projects its beak from the water and opens it slightly. It thus remains motionless until the birds approach and thoughtlessly perch upon the beak, deeming it a reed or a bush; then the treacherous ensnarer seizes the feet of the unfortunate birds by closing its beak, and, dragging them into the water, devours them.[68] The birds are fully as abundant as the fishes. During certain months of the year the pigeons sally forth from the woods into the open country in such great numbers that they overload the branches of the trees. When they have settled upon the trees at night they are easily captured, and the savages heap their tables with royal abundance. Besides this, in the huge gulf into which the river saint Lawrence flows may be seen a small island, or rather a double rock; they call it the isle of birds.[69] For so many congregate there from the neighboring ocean that it is impossible to count their numbers. The natives make an easy prey of them with clubs, or by trampling them under foot, and bring back their canoes filled with sumptuous food acquired without price. [345] Everywhere may be seen, sporting in the water, geese, ducks, herons, cranes, swans, coots and other birds whose habit it is to seek their living from the waves. A certain peculiarity attaches to one, which is about the size of a cock; its wings are black on the outside and white beneath. One of its feet is armed with hooked claws, the other has webbed toes, like those of a duck; with the latter it swims, with the former it seizes and disembowels fishes.
