A TRUSTWORTHY writer in one of our exchanges says that last summer near his room a humming-bird built her tiny nest and reared her family. One day when there was a heavy shower coming up, just as the first drops fell the mother came fluttering home, seized a large leaf which grew on the tree near her nest, drew it over the nest in a way to completely cover it, then went back to whatever work she had been about when the coming storm disturbed her. The amused watchers from the window wondered why the leaf did not blow away, and finally reached out and examined it; they found it hooked to a tiny stick which was just inside the nest, as if it had been built in for that purpose! The storm lasted but a few minutes, and after it was over home came the mother, unhooked the green curtain she had so carefully put up, and found her babies perfectly dry.
