ontier by the pioneers of our civilization, have always extended, in wild swarms, a little distance into the wilderness. But, at most, they appear to have wandered only for a few miles beyond the homestead, going no further away than would permit their use of the cultivated plants. The aborigines early learned to regard the insect as the _avant courier_ of European men. When they came upon an individual of the species they always knew that some white man's dwelling stood nearby. Those who are familiar with the solitudes of our Appalachian forests must often have remarked, in the stillness of a summer day, the hum of a swarm from some forest or domestic hive in its search for a dwelling-place. Those who have followed up the movements of these migrating colonies have had a chance to perceive how long is the search before they find a fit abiding place. Doubtless by far the greater part of these searchers for a home fail of their quest, and the wandering swarms perish without finding a suitable shelter. In certain kinds of woods, as, for instance, those occupied by pine trees or other species which do not develop spacious hollows in their trunks, and where there are no crannied rocks--all the swarms which seek habitations there are foredoomed to destruction. If by chance the colonies wander too far, they generally find the wilderness so ill provided with plants which may furnish them with the sources of wax, honey, or other necessaries, that they cannot maintain their life. Thus it is that the bee, though domiciled with us rather than domesticated, has become united in its fortunes with civilization. In this position they have shown a remarkable adaptation to extremely varied conditions. They can withstand any climate which permits the development of the vegetation to which they need have access, provided the growing season continues long enough to accumulate their store. In the tropical lands they harvest so little honey that they are not profitable to man, and in the high north they need all their summer's accumulation to maintain them through the long winter. Thus, though they may range almost as far as man through the gamut of climates, they are profitable to their masters only in the middle latitudes. They commonly do not do well close to the sea, and cannot be kept on inconsiderable islands for the reason that they are, in their wanderings, likely to be lost in the waters. The bee, like the other social insects, evi
