While on those trips, they frequently passed an island on one of the ledges of which, they often saw a monster sea lion--the largest among the thousands in that locality.

One of his crew assured Paul that that lion was known to all the fisherman and was remarkably cunning.

Boyton at once made up his mind to capture the brute.

With that purpose in view, he ran the sloop for several days to a point behind the island near the big lion's resting place, in order to get him accustomed to their presence.

He was always found occupying the same ledge of rock, surrounded by smaller lions.
