So Uncle Nelson took the delicate machinery apart, and found some particles of dirt, which prevented the piston from working smoothly. Then he cleaned and oiled it, put it together again, and once more it started. This time it was a complete success. How Bertie clapped his hands, as the steam hissed, and the boat went round and round, as if it were alive!

It was half an hour before the water in the little boiler gave out.

A STORY ABOUT SQUIRRELS.

Freddie is a bright little boy six years old. He goes with his papa and mamma every summer to stay a few months at a nice place in the country. In front of the house, near the fence, stands a large elm-tree, which is the home of many little squirrels.

One day Freddie got his papa to build him a small shelf on the tree, about four feet from the ground, so that he could put nuts on it to feed the squirrels. At first the little fellows were very shy, and would not come near the shelf, but sat on the branches of the tree; and we fancied that we heard them saying to each other, "Do you think that little boy would hurt us, if we should run down, and take one of those nuts?"

But, after a while, they came down, one by one, took the nuts, and went scampering up to the top branches; and in a few minutes down came the empty shells. They grew so tame before the summer was over, that if we put any thing on their shelf, and took a seat a few steps away, they would come down quite boldly, and get their breakfast.
