A custom among whalemen in the Arctic seas, that the iron holds the whale, is reasonable and valid to bestow title upon the party who first harpoons a whale. The usage for the first iron, whether attached to the boat or not, to hold the whale, is fully established.
A fisherman shot a fin-back whale with a bomb-lance identifiable as belonging to him, which caused it to sink to the bottom of the ocean. A local custom existed in the community that when a whale resurfaced, the fisherman would be notified and the finder would be paid a small salvage fee for his services. In this case, the whale was found on the beach by a third party, who sold it to respondent. The fisherman sued respondent for conversion of the whale.
