wrote about fishing for Atka mackerel on May 28, 1892, in ''American Food and Game Fishes'':

The fish were in schools and it was easy to get great numbers; in fact, one would be kept very busy hauling in the fish and taking them off the hook... When first hooked they would come up very readily, in fact they seemed to swim upward until near the surface when they would become alarmed and dart back and forth in their efforts to free themselves. The sport was very exciting. During 4 hours fishing 9 persons with 26 lines took 585 fish... And as our ship was out of fresh meat of every kind, all these fish were soon eaten by the officers and crew.Jordan, David. Barton Evermann. American Food and Game Fishes. New York.
