“The disappearance of martins is a loss really of national importance,” he began, in a sickly whine. “It is a shame to see how the pretty house martins are decreasing in this country at the hand of the sparrows,” he continued. “He drives away our migratory and pre-eminently useful insect-eating birds, even turning out the eggs of the owners and using the locality for its own nest.”

He was obviously quoting from the pro-martin authorities, and I stopped him.

“I have heard all that before,” said I.

“There’s a fair amount of it about, pages and pages,” said he; “there’s one story, for instance, of twenty or thirty martins blocking up the bold, bad sparrow inside the nest, which the said bold, bad sparrow had usurped. What do you think of that?”

“I think it is untrue,” I promptly replied.

“It is untrue,” said he; “but it isn’t far away from truth, for all that. Many a dead sparrow has been found in a martin’s-nest, and many a time the entrance was too small for a sparrow to have got out of; but, still, it wouldn’t take a healthy sparrow long to break up a martin’s-nest.”

“What has happened then?” said I.
