tenanted by twenty or thirty ,,., pairs of Martins; others are plain, unpainted soap boxes or the like, but the birds seem to take to one as kindly as the other, making nests in their compartments of weeds, feathers, etc. They also, and most commonly in the west, nest in cavities of trees making nests of any available material. During June

Barn Swallow
613. BARN SWALLOW. gastra.
Range. Whole of North America; winters south to South America.
This Swallow is the most beautiful and graceful of the family, and is a familiar sight to everyone, skimming over the meadows and ponds in long graceful sweeps, curves and turns, its lengthened outer tail feathers streaming behind. Throughout their range, they nest in barns, sheds or any building where they will not be often disturbed, making their nests of mud and attaching them to the rafters; they are warmly lined with feathers and the outside is rough, caused by the pellets which they place on the exterior.
Before the advent of civilized man, they attached their nests to the sides of caves, in crevices among rocks and in hollow trees, as they do now in some localities. Their eggs cannot be distinguished from those of the Cliff Swallow. Data. Penikese Is., Mass., July 2, 1900. Nest on beam in sheep shed; made of pellets of mud, lined with feathers.
614. TREE SWALLOW; WHITE-BELLIED SWAL LOW. Iridoprocne bicolor.
Range. Whole of temperate North America, breeding from middle United States northward; winters in the Gulf States and along the Mexican border and southward.
This vivacious and active species is as well known as the last, and nests about habitations on the outskirts of cities and in the country.
