Passing by Mrs. Brett's cottage they saw the old lady beckoning to them. When they went to her she explained that she wanted them to aid her swallows. A pair of house-martins were flying about their nest in the eaves, uttering cries of distress.
"What is the matter? Have the sparrows taken possession of it?" said Frank.
House-martin.
"No, dear, but it seems breaking away from the wall. There are young ones in it, and I suppose the old birds did not make it strong enough to hold their weight. I am afraid it will fall down every minute."
The boys undertook to put matters right, and with the aid of a ladder they climbed up to the nest, and with a hammer and nails they nailed up the nest in a broad piece of flannel. While they were engaged in doing this, the martins ceased their cries, as if they knew that a friendly act was being done for them; and when the boys left the nest the birds returned to it, and by their busy twitterings and short excited flights seemed to wish to express their gratitude.
Leaving the cottage, they went for a long aimless ramble through the fields and woods, trespassing with impunity, for they were well known everywhere, and visiting every hedgerow and copse on the look-out for nests.
