22 all my life at last boiled over, and, resolving that the martins should have one safe place, I began to protect them by killing down the sparrows. It was a hard fight at first; the martins' nests had to be watched almost constantly, and, if I remember rightly, 150 sparrows were shot—mostly about these nests—in about a fortnight. War has been waged against them ever since. The first year or two we did not take the trouble to kill them in winter, but this did not answer; a great number lived about the place, many roosting in the martins' nests. When we began shooting the sparrows in spring they would all go away for a day or two, but kept coming back again, so that constant watchfulness for weeks was required to kill them down; the plan was therefore adopted of paying a penny for shooting each sparrow as soon as it shows itself all the year round. They are shot with very small charges of dust shot, mostly from inside doors and windows, or from loopholes made to command the places they generally come to; they dislike this practice, and do not come much—less and less every year. The plan has been most successful; the place is wonderfully free from sparrows—sometimes we do not see one for weeks together—and the martins have increased in numbers, till last year they had 170 nests about my house and buildings, and this year there are 237, and more will be built yet.

The food in the sparrows killed at first (June, 1870) was examined and found to be mostly corn and broken maize, for which they went to a farmyard nearly half a mile off. In this way becoming much interested in the subject, I investigated the food and habits of sparrows with special care during some seven years, and worked pretty hard collecting from a wide extent of country, and
