“It is two years now that the first martin house has been up, and yet I have never had any martins to stay!” said the boy. “They would come, go into the house and twitter, and then fly away.”

He began talking again about his manual training teacher: how she called one day, and told him that the martin house was mounted too low, and too near trees; that martins want to be fifty feet away from a tree or building, and sixteen feet up from the ground; also, that it pleases martins to have openings near the ceiling of their rooms so they can have a change of air.

I remarked that this ventilation would make their rooms more comfortable.

“Yes,” said the boy; “and this new martin house is made according to teacher’s directions.”

As we stood there, martins were flying about, twittering, singing, perching on the telephone wires near by and on the roof and the porches of their house. The pole had hinges so that the house could be brought down and cleaned, when necessary, or closed.

One lovely June day found me again at the boy’s home. I remarked the large number of young robins on the lawn.

“The young have just left their nests in that tree,” answered the boy, pointing into a big cherry tree. “Robins have nested in that tree every year since I can remember.”

I guessed that perhaps the cherries were the attraction.

“Well,” he said, “we think birds earn all the cherries they eat; we never pick those on the top branches at all, but leave them for the birds.”

During that visit the boy showed me several bird homes. First he apologized for doing it. “Every bird home is a secret between mother and me,” he said; then added, “but I know I can trust you.”
