A pair of these Warblers have a nest in one of the elder bushes by our fence, and they wouldn't mind a bit if we went to look at them.

Would it be too far for you to come, sir ?" he inquired timidly of the Doctor, evidently proud of having something to show.
[Illustration: Yellow Warbler] "We shall be glad to see the nest, my boy.

How is it that you have so many birds about your house ?" "I think it's partly for the same reason that you have birds here--for we don't keep cats either--and it's partly because we have four big old mulberry trees." "What have mulberry trees to do with birds ?" asked Nat, without stopping to think.
"Everything," said the Doctor.

"The mulberry is one of the most attractive fruits to our familiar birds, and at least twenty-five species feed upon it greedily.
"Whoever plants a mulberry tree in his garden sends a public invitation through Birdland for its people to come and live with him.

The invitation is always accepted, and the birds appreciate the kindness so much that when they find mulberries they leave the cherries and strawberries in that garden in peace.
