The "pit," an artificial pool in the bank of which the bone deposit ceased about four feet below the present surface of the plain. small boulders, seeds, cones of trees yet native in the mountains, several species of insects, leaves, twigs, broken limbs and badly worn trunks of trees—all massed together and most certainly brought together by wash. Parts of skeletons were found in most unusual places as a rib or a tooth, or a carpal in the neural canal of a ver- tebra or the scutes of the giant ground sloth, the phalanges of the wolf and a tooth of the lion in the cranial cavity of some skull. The specimens show a larger number of aged and younger indiv- iduals than of the middle aged ones. The skeletons were never com- plete, it being the rarest occasion when the major part of a skeleton of an individual could be found, and only such parts of the many as could resist destruction—limb bones, vertebrae, skulls and teeth are the most common finds. The elements of the skeleton were invariably separate, scattered, and most often fragmentary, doubtless by having suffered complete separation and scattering on the. plain, break and wear in the transportation, decay outside the preserving tar or gnaw- ing by the carnivorous animals. Occasionally two or more consecu- tive bones, e. g. vertebrae were found together, but only because of adhesions in disease. Again the skeletal elements were found in the most topsy-turvy relation possible. For example to remove from the 64.
