Magnificently built, 26-year-old Captain Wallace Caswell, Jr, follows the worlds most perilous profession. He fights and kills sharks for a living, and in this unparalleled series of pictures he is shown in a deep sea fight with the monster shark. A wonderful swimmer, Caswell first taught of fighting sharks in their own element when they ripped and destroyed his fishing nets. He has two methods of killing - by the knife and by thrusting his arms in the gills and drowning them. Although he has many encounters with the monsters, Captain Caswell has only been injured twice, but he bears a silver plate in his head as a grim reminder of a fight with a swordfish. Photo shows: Captain Wallace Caswell slashes again and again as the shark attempts to get into striking position. 6 March 1937
