All the tents were made open to the sky in the centre, but closed in at either extremity with a curious semicircular top.

[PLATE CIX., Fig.

1.] The two tops were unequal of size.

Internally, either both of them, or at any rate the larger ones, were supported by a central pole, which threw out branches in different directions resembling the branches of a tree or the spokes of a parasol.
Sometimes the walls of the tent had likewise the support of poles, which were kept in place by ropes passed obliquely from the top of each to the ground in front of them, and then firmly secured by pegs.

Each tent had a door, square-headed, which was placed at the side, near the end which had the smaller covering.
