Tree-frogs have, of course, in most circumstances much greater difficulty in getting at water than pond-frogs; and this is especially true in certain tropical or desert districts. Hence most of the frogs which inhabit such regions have had to find out or invent some ingenious plan for passing through the tadpole stage with a minimum of moisture. The devices they have hit upon are very curious. Some of them make use of the little pools collected at the bases of huge tropical leaf-stalks, like those of the banana plant; others dispense with the aid of water altogether, and glue their new-laid eggs to their own backs, where the fry pass through the tadpole stage with the slimy mucus which surrounds them. Nature always discovers such cunning schemes to get over apparent difficulties in her way: and the tree-frogs have solved the problem for themselves in half a dozen manners in different localities. Oddest of all, perhaps, is the dodge invented by "Darwin's frog," a Chilean species, in which the male swallows the eggs as soon as laid, and gulps them into the throat-pouch beneath his capacious neck: there they hatch out and pass through their tadpole stage: and when at last they arrive at frogly maturity, they escape into the world through the mouth of their father.
The last blow came to me that evening, when my men informed me that we had no food whatever left. All that remained of our three months' provisions were six tins of sardines and one tin of anchovies. That was all. My men made no secret of having thrown away everything as we came along. The sugar, for which they had a perfect craving, they had eaten, consuming in the last two days the entire supply of 30 lb., which had remained until then. It was then that I understood the cause of the internal inflammation from which they all suffered. They were greatly excited, and demanded the balance of their money, not wishing to come on any more; they wanted to fall back on the River Tapajoz and go home. There was a riot. They threatened to shoot me if I insisted on their coming on.
