"What does evaporate mean," asked Tommie bringing out the long word with a jerk.

"Do you remember, dear," answered Mamma, "that early in the morning when the grass is all wet with dew, my little boy cannot run in it without his rubbers? But before long it is all dry and then my little boy takes off his rubbers and does not get his feet wet. The sun and the air absorb or suck up the water and carry it off to their homes. Now, the bubbles are made of a little water and a little air. The water is on the end of the pipe, and Tommie blows the air into the pipe, and the bubble grows big and round. When it breaks, the air sucks up the water, which was the outside of the bubble, and the air which was inside mixes with the air in the room."

"Now do you suppose you can tell Papa all about it, when he comes home to dinner?" asked Mamma.

"Of course I can," said Tommie, proudly. "Haven't you just told me all about it?"
