“I shall be most happy,” replied the Hyla, slipping into the water in a jiffy, and in a second later he was resting on the bottom of the pool, just under Mrs. Water Spider’s glittering balloon.

“That certainly is very beautiful, Mrs. Spider. Would you mind explaining how it is done?” said he.

“Not at all,” said the spider, as she came and sat in the door of her home. “My house, sir, is woven of silk, just as are those of other spiders, but instead of a web I weave this egg-shaped nest with the door at the bottom. Now, although I live under water, I breathe air, and it is necessary for me to fill my house with it. So up to the top I go and catch a bubble of air with the hairs of my abdomen and my two hinder legs. I then bring it down here and hang it in my silken balloon until it is, as you see, a glittering, transparent bell. In the top of my nest I weave a little chamber in which to lay my eggs, and when my babies hatch out they stay in this shining home until they are strong enough to build a nest for themselves.”

“And how many eggs, Mrs. Spider,” asked Hyla, politely, “do you put in the chamber?”

“A hundred is the usual number,” replied Mrs. Spider, “but now you really must excuse me, as I am in need of more air.”

“Goodness gracious,” mused the tree-toad, looking after her as she darted toward the top. “I should think she would feel something like that old woman who lived in a shoe, who had so many children she didn’t know what to do. But what have we here?” and Mr. Hyla leaned forward to watch a wee log hut that was creeping in the queerest way on a water-weed.

“Ugh! What great goggle eyes you have!” piped a tiny voice from the door of the hut. “I should like to know what you are staring at.”

“Well, this is surprising,” gasped the Hyla. “Now, who in the world are you?”

“I am a caddis-worm out for an airing,” said the voice again, as the hut reached the edge of the leaf. “I hope you have no objections.”
