Compared with his rival, the frog, the toad reacts more promptly and learns more readily. Toads can figure out a maze far more quickly than frogs can. They discover after eight or nine trials that a glass barrier cannot be passed, whereas frogs keep bumping their noses against it. When set on a high table, toads will peer cautiously over the edge, appearing to estimate the drop, and then refuse to jump. Frogs will fling themselves off anything . . . another indication of the toad's mental capacities is that he is easily tamed. Toads in captivity learn to come out of hiding when called and to feed from the hand. They seem to enjoy being petted and stroked.
