In a subsequent portion of this narrative I shall have frequent occasion to mention this species of tortoise. It is found principally, as most of my readers may know, in the group of islands called the Gallipagos, which, indeed, derive their name from the animal--the Spanish word Gallipago meaning a fresh-water terapin. From the peculiarity of their shape and action they have been sometimes called the elephant tortoise. They are frequently found of an enormous size. I have myself seen several which would weigh from twelve to fifteen hundred pounds, although I do not remember that any navigator speaks of having seen them weighing more than eight hundred. Their appearance is singular, and even disgusting. Their steps are very slow, measured, and heavy, their bodies being carried about a foot from the ground. Their neck is long, and exceedingly slender; from eighteen inches to two feet is a very common length, and I killed one, where the distance from the shoulder to the extremity of the head was no less than three feet ten inches. The head has a striking resemblance to that of a serpent. They can exist without food for an almost incredible length of time, instances having been known where they have been thrown into the hold of a vessel and lain two years without nourishment of any kind--being as fat, and, in every respect, in as good order at the expiration of the time as when they were first put in. In one particular these extraordinary animals bear a resemblance to the dromedary, or camel of the desert. In a bag at the root of the neck they carry with them a constant supply of water. In some instances, upon killing them after a full year's deprivation of all nourishment, as much as three gallons of perfectly sweet and fresh water have been found in their bags. Their food is chiefly wild parsley and celery, with purslain, sea-kelp, and prickly pears, upon which latter vegetable they thrive wonderfully, a great quantity of it being usually found on the hillsides near the shore wherever the animal itself is discovered. They are excellent and highly nutritious food, and have, no doubt, been the means of preserving the lives of thousands of seamen employed in the whale-fishery and other pursuits in the Pacific. The one which we had the good fortune to bring up from the storeroom was not of a large size, weighing probably sixty-five or seventy pounds. It was a female, and in excellent condition, being exceedingly fat, and having more than a quart of limpid and sweet water in its bag. This was indeed a treasure; and, falling on our knees with one accord, we returned fervent thanks to God for so seasonable a relief.
