Here and there on the shore was a dome-shaped ant's nest with a pathway to it from the pond, showing, as the Indian said, that here the beaver came on sunny days to lie on the hill and let the swarming ants come forth and pick the vermin from their fur.

At one high point projecting into the still water they found a little mud pie with a very strong smell; this, the Indian said, was a "castor cache," the sign that, among beavers, answers the same purpose as the bear tree among bears.
Although the pond seemed small they had to tramp a quarter of a mile before reaching the upper end and here they found another dam, with its pond.

This was at a slightly higher level and contained a single lodge; after this they found others, a dozen ponds in a dozen successive rises, the first or largest and the second only having lodges, but all were evidently part of the thriving colony, for fresh cut trees were seen on every side.

"Ugh, good; we get maybe fifty beaver," said the Indian, and they knew they had reached the Promised Land.
Rolf would gladly have spent the rest of the day exploring the pond and trying for a beaver, when the eventide should call them to come forth, but Quonab said, "Only twenty deadfall; we should have one hundred and fifty." So making for a fine sugar bush on the dry ground west of the ponds they blazed a big tree, left a deadfall there, and sought the easiest way over the rough hills that lay to the east, in hopes of reaching the next stream leading down to their lake..
