Before I set up my tent I drew a half-circle before the hollow place, which took in about ten yards in its semi-diameter from the rock, and twenty yards in its diameter from its beginning and ending.
Antes de montar mi tienda, tracé un semicírculo delante de la cavidad, de un radio aproximado de diez yardas hasta la roca y un diámetro de veinte yardas de un extremo al otro.
