concerning the house, previously to quitting the Knoll; and he was now
well pleased to perceive that they had been attended to. As this spot
will prove the scene of many of the incidents we are bound to relate,
it may be proper, here, to describe it, at some length.

The hillock that rose out of the pond, in the form of a rocky little
island, was one of those capricious formations that are often met with
on the surface of the earth. It stood about thirty rods from the
northern side of the area, very nearly central as to its eastern and
western boundaries, and presented a slope inclining towards the south.
Its greatest height was at its northern end, where it rose out of the
rich alluvion of the soil, literally a rock of some forty feet in
perpendicular height, having a summit of about an acre of level land,
and falling off on its three sides; to the east and west precipitously;
to the south quite gently and with regularity. It was this accidental
formation which had induced the captain to select the spot as the site
of his residence; for dwelling so far from any post, and in a place so
difficult of access, something like military defences were merely
precautions of ordinary prudence. While the pond remained, the islet
was susceptible of being made very strong against any of the usual
assaults of Indian warfare; and, now that the basin was drained, it had
great advantages for the same purpose. The perpendicular rock to the
north, even overhung the plain. It was almost inaccessible; while the
formation on the other sides, offered singular facilities, both for a
dwelling and for security. All this the captain, who was so familiar
with the finesse of Indian stratagem, had resolved to improve in the
following manner:

In the first place, he directed the men to build a massive wall of
stone, for a hundred and fifty feet in length, and six feet in height.
