Alligators Swallowing Stones.
Reading edition
The alligators on the banks of the Oronoko, previous to going in search of prey, swallow large stones, that they may acquire additional weight to aid them in diving and dragging their victims under water. Bolivar shot several with his rifle, and in all of them were found stones varying in weight according to the size of the animal. The largest killed was about seventeen feet in length, and had within him a stone which weighed sixty or seventy pounds.
