ADDY sat looking thoughtfully at the aspen-trees he would have to cut to complete his store of food for the winter. All those near the edge of his pond had been cut. The others were scattered about some little distance away. "I don't know," said Paddy out loud. "I don't know."

"What don't you know?" asked Sammy Jay, who, now that he and Paddy had become friends, was very much interested in what Paddy was doing.

"Why," replied Paddy, "I don't know just how I am going to get those trees. Now that Old Man Coyote is watching for me, it isn't safe for me to go very far from my pond. I suppose I could dig a canal up to some of the nearest trees and then float them down to the pond, but it is hard to work and keep sharp watch for enemies at the same time. I guess I'll have to be content with some of these alders growing close to the water, but the bark of aspens is so much better that I—I wish I could get them."

"What's a canal?" asked Sammy abruptly.

"A canal? Why, a canal is a kind of ditch in which water can run," replied Paddy.

Sammy nodded. "I've seen Farmer Brown dig one over on the Green Meadows, but it looked like a great deal of work. I didn't suppose that any one else could do it. Do you really mean that you can dig a canal, Paddy?"

"Of course I mean it," replied Paddy, in a surprised tone of voice. "I have helped dig lots of canals. You ought to see some of them back where I came from."

"I'd like to," replied Sammy. "I think it is perfectly wonderful. I don't see how you do it."

"It's easy enough when you know how," replied Paddy. "If I dared to, I'd show you."

Sammy had a sudden idea. It almost made him gasp. "I tell you what, you work and I'll keep watch!" he cried. "You know my eyes are very sharp."
