“They’re not very hard to catch,” she told me. “They freeze in the beam of light so you can just grab them.” The toads, which are warty, sand colored, and roughly the size of a man’s hand, have a large gland on each side of their necks, and smaller ones on their legs. “You gently squeeze the gland while holding a mirror in front of it to catch the spray.” The toad is apparently none the worse for being milked. Overnight, the venom dries on the glass, turning into flaky crystals the color of brown sugar.
