For choosing the gap over the tree, use is made from the dimensions of toes marked at the tents. the dimensions on both sides starts on the best of the tent and the determine at the scale on the element the place it reaches the floor indicates the space from the head to the ground, on either side, and the precise distance over the tree are available by means of including those figures, supplied one of many traces on which the dimensions is marked is over the precise heart of the tree.
