One of the beavers ventured to go upon the breach, after having several times approached it, and returned again like a spy. I lay in ambush in the bottom, at the end of the dam: I saw him return; he surveyed the breach, then struck four blows, which saved his life, for I then aimed at him. But these four blows, so well struck, made me judge it was the signal of call for all the rest, just as the night before. This also made me think he might be the overseer of the works, and I did not choose to deprive the republic of beavers of a member who appeared so necessary to it. I therefore waited till others should appear: a little after, one came and passed close by me, in order to go to work; I made no scruple to lay him at his full length, on the persuasion he might only be a common labourer. My shot made them all return to their cabins, with greater speed than a hundred blows of the tail of their Overseer could have done. As soon as I had killed this beaver, I called my companions; and finding the water did not run off quick enough, I caused the breach to be widened, and I examined the dead.

I observed these beavers to be a third less than the brown or common sort, but their make the same; having the same head, same sharp teeth, same beards, legs as short, paws equally furnished with claws, and with membranes or webs, and in all respects made like the others. The only difference is, that they are of an ash-gray, and that the long pile, which passes over the soft wool, is silvered, or whitish.

During this examination, I caused my people to cut boughs, canes, and reeds, to be thrown in towards the end of the pond, in order to pass over the little mud which was in that place; and at the same time I caused some shot to be fired on the cabins that lay nearest us. The report of the guns, and the rattling of the shot on the roofs of the cabins, made them all fly into the woods with the greatest precipitation imaginable. We came at length to a cabin, in which there were not six inches of water. I caused to undo the roof without breaking any thing, during which I saw the piece of aspin-tree, which was laid under the cabin for their provisions.

I observed fifteen pieces of wood, with their bark in part gnawed. The cabin also had fifteen cells round the hole in the middle, at which they went out; which made me think each had his own cell.

I am now to give a sketch of the architecture of these amphibious animals, and an account of their villages; it is thus I call the place of their abode, after the Canadians and the Indians, with whom I agree; and allow, these animals deserve, so much the more to be distinguished from others, as I find their instinct far superior to that of other animals. I shall not carry the parallel any farther, it might become offensive.

The cabins of the beavers are round, having about ten or twelve feet in diameter, according to the number, more or less, of fixed inhabitants. I mean, that this diameter is to be taken on the flooring at about a foot above the water, when it is even with the dam: but as the upper part runs to a point, the under is much larger than the flooring, which we may represent to ourselves, by supposing all the upright posts to resemble the legs of a great A, whose middle stroke is the flooring. These posts are picked out, and we might say, well proportioned, seeing, at the height this flooring is to be laid at, there is a hook for bearing bars, which by that means form the circumference of the flooring. The bars again bear traverses, or cross pieces of timber, which are the joists; canes and grass complete this flooring, which has a hole in the middle to go out at, when they please, and into this all the cells open.

The dam is formed of timbers, in the shape of St. Andrew's cross, or of a great X, laid close together, and kept firm by timbers laid lengthwise, which are continued from one end of the dam to the other, and placed on the St. Andrew's crosses: the whole is filled with earth, clapped close by great blows of their tails. The inside of the dam, next the water, is almost perpendicular; but on the outside it has a great slope, that grass coming to grow thereon, may prevent the water that passes there, to carry away the earth.

I saw them neither cut nor convey the timbers along, but it is to be presumed their manner is the same as that of other Beavers, who never cut but a soft wood; for which purpose they use their fore-teeth, which are extremely sharp. These timbers they push and roll before them on the land, as they do on the water, till they come to the place where they want to lay them. I observed these grey Beavers to be more chilly, or sensible of cold, than the other species: and it is doubtless for this reason they draw nearer to the south.

We set out from this place to come to a high ground, which seemed to be continued to a great distance. We came the same evening to the foot of it, but the day was too far advanced to ascend it. The day following we went to its top, found it a flat, except some small eminences at intervals. There appeared to be very little wood on it, still less water, and least of all stone; though probably there may be some in its bowels, having observed some stones in a part where the earth was tumbled down.
