Three black ink drawings of a round hut: the top drawing sets the hut in its landscape, with the sea and a European ship in the right hand of the background (much like the watercolour drawing BTL/2/1/3); the middle drawing is a cross section of the hut from the centre of the roof, looking down on a fire pit in the centre of the circular room, with the door below; the lower drawing is a lateral cross section of the hut, looking out of the door in the centre, showing the structure of the roof and thickness of the walls.
