On the end of the back building was fastened a strong pole, running up into the air some ten feet.

On the top of this pole was a bird-box, in which a pair of pigeons had their nest.

Two young pigeons had been hatched out, and now nearly full-fledged and ready to fly, they were thrusting their glossy heads from the box, and looking about from their airy height.
A fluttering of wings, as the mother-bird returned with food for her young ones, attracted the attention of Andrew, and looking up, he saw the young pigeons.

Instantly came a desire to remove them from their nest.

But the way to that nest was too difficult and perilous for him to think of securing his wish.
