Entrance is gained to the house by a square hole in the flooring, and the primitive staircase by which the inhabitants ascend into their houses is equally simple and effectual. It is necessary that the stairs--if we may use the term--should be so constructed, that while human beings can easily obtain access to the house, the rats and other vermin shall be kept out. If an ordinary ladder or even a notched pole were fixed to the house, the rats and snakes would be sure to climb up it and take possession of the dwelling. The native architect, therefore, proceeds after a different fashion. Immediately under the opening in the floor he fixes two stout posts in the ground, leaving them to project rather more than three feet. The posts have forked heads, and upon them is laid a transverse pole, which is firmly lashed to them. From this transverse pole another pole is laid to the ground, so as to form an inclined plane up which the inhabitants of the house can walk. It will now be seen, that if a man walk up the inclined pole, to the transverse one, he can pass along the latter in a stooping attitude until he comes to the opening in the floor. He can then pass his body through the opening and lift himself to the level of the floor, while the space which intervenes between the horizontal post and the floor affords an effectual barrier against the rats and other vermin. The reader will better understand this description by comparing it with illustration No. 1, on the 916th page, which represents three of these huts. That on the right is seen from the end, and is represented as half finished, in order to show the structure of the interior. The sides and roof of the hut are formed of slight spars which are lashed together by a framework, so as to form a support for the thatching. This is made of coarse grass pulled up by the roots in large tufts, and covered with an outer layer of cocoa-nut leaves. If the house be a large one, there is an entrance at each end, and another in the middle, each being closed with neatly woven mats. Similar but coarser mats are fastened to the lower portion of the sides, in order to exclude the wind. Up to this point the architecture is identical throughout the island, but a divergence takes place in the shape of the house itself, according to the locality. The usual form is that which is represented in the illustration. Such a house as is there drawn is on the average thirty feet in length, nine in width, and thirteen in total height, so that a space of about three feet intervenes between the upper floor and the roof. The central figure of the illustration shows the side view of a finished hut, and the left-hand figure shows the end view of a similar dwelling.
