Recovery from near extinction

In 1892 Doctor Townsend and myself were sent to Guadalupe Island by the State Department to secure evidence of the occurrence there of fur seals, and found, to the surprise of all naturalists, nine of the supposed extinct elephant seals. Acting again on the plan of saving them from the oil barrel, we shot seven, only three of which we were able to take from the beach, owing to the heavy surf.
