At each corner was a two-storied loop-holed block-house to act as a bastion.

The stout log-cabins were arranged in straight lines, so that their outer sides formed part of the wall, the spaces between them being filled with a high stockade, made of heavy squared timbers thrust upright into the ground, and bound together within by a horizontal stringer near the top.

They were loop-holed like the block-houses.

The heavy wooden gates, closed with stout bars, were flanked without by the block-houses and within by small windows cut in the nearest cabins.

The houses had sharp, sloping roofs, made of huge clapboards, and these great wooden slabs were kept in place by long poles, bound with withes to the rafters.
