How does the toad catch its prey orseize the offered food? Both toads and frogs do much good by destroying manyinsects. One observer, quoted by Professor Gage, reportsthat a single toad disposed of twenty-four caterpillars inten minutes, and that another ate thirty-five celery-wormswithin three hours. This observer estimates that a good-sized toad will destroy nearly ten thousand insects and wormsin a single summer. The garden can have no more desirableanimal inhabitants than toads; not only should they not bekilled but it would be worth while to introduce them into flowerand vegetable gardens where they are not naturally present.

H. 102 THE ANIMALS AND MAN BIRDS The animals whose life-history we have so far studieddo not take care of their young, though making certainprovision for them nevertheless. The female mosquito,although an aerial creature, is careful to lay her eggs onthe surface of water so that the young will find themselvesat the moment of hatching in their proper element; thefemale moth or butterfly, although she never eats leaves her-self, always lays her eggs on the plants or trees wherethe young, on hatching, can find at hand their properleaf food. Such is the habit of all moths and of them indeed take no food in their adult stage;others do, but this is always liquid nectar from flowers, orother sweet juices, and water, and their mouth-parts areformed into a long flexible, coiling, sucking proboscis. Theycould not eat green leaves if they would; and yet each mothand butterfly mother seeks out, at egg-lay
