We learn, too, that grasshoppers and other insects annually destroy fifty-three million dollars' worth of hay and that two million dollars' worth of cereals are each year eaten by our insect population. In fact, we are told that one-tenth of all the cereals, hay, cotton, tobacco, forests, and general farm products is the yearl

Naturalists call it Colaptes auratus, but name it as you may, this bird of many aliases is well worthy of the esteem in which it is held. It gathers its food almost entirely from the ground, being different in this respect from other Woodpeckers. One may flush it in the grove, the forest, the peanut fi

Without the assistance of ants, it appears that the plant lice would be unable to reach the roots of the corn. In return for these attentions the ants feast upon the honey-like substances secreted by these aphids. The ants, which have the reputation of being no sluggards, take good care of their diminutive milch cattle, and will tenderly pick them u

It is readily seen that thirty seeds a minute was below the average of these birds; and if each bird ate at that rate for but a single hour each day it would destroy eighteen hundred seeds a day, or twelve thousand six hundred a week.

In some of the American ports incoming vessels are systematically fumigated to kill the rats for fear they may bring with them the bubonic plague. In April, 1898, while engaged in field natural history work in Hyde County, North Carolina, I found the farms alo

Some years ago the naturalist, Dr. A. K. Fisher, discovered that a pair of Barn Owls had taken up their abode in one of the towers of the Smithsonion Institution building. He found the floor thickly strewn with pellets composed of bones and fur which these birds and their young had disgorged. He collected two hundred of these and

So important and yet so unexpected is the ultimate effect of the activities of predatory creatures that in a state of nature I am convinced the supply of game birds is increased rather than decreased by being preyed upon. Like all other creatures, birds are subject to sickness and disease, but by the laws of nature it appears that they are not designed to suffer long. Their quick removal is advisable if they are to be prevented from spreading contagion among their fellows, or breeding and passing on their weakness to their offspring. Sometimes the Haw
