The submerged plumbing in Lake Yamamoto needs to be inspected. Goto Dengo has Rodolfo ask around and see if there are any men among them who have worked as pearl divers. He quickly finds one, a lithe, frail-looking fellow from Palawan, named Agustin. Agustin is weak from dysentery, but he seems to perk up around water, and after a couple of days’ rest is diving down to the bottom of Lake Yamamoto with no trouble. He becomes another one of Rodolfo’s picked men.
