We have now arrived at an important division of the feathered tribes, all the members of which are more or less terrestrial. They generally procure their food from the surface of the ground, upon which they run or walk with facility, and many of them scratch up the earth in search of such nutritive materials as serve for their subsistence. They have, therefore, in conformity with such a mode of life, a short or moderately long beak, which is usually vaulted above. Their body is heavy, and their wings generally short. They all live principally upon grain, and are furnished with a strong muscular gizzard. To this order belong our game birds, and most of our poultry. Their flesh is edible, and supplies us with wholesome and nutritious food, and from the facility with which they are procurable, and the ease with which some are domesticated, are of the utmost importance to mankind. The members of this division were separated by Cuvier into two sections--the COLUMBÆ, or Pigeons, and the GALLINÆ, properly so called. More recently, however, these sections have been considered as forming two distinct orders, distinguished by the names of the PIGEONS (_Gyratores_) and the SCRAPERS (_Rasores_), or TRUE GALLINACEOUS BIRDS. PIGEONS. The place which the Pigeons ought to occupy in the zoological system has been a very fertile subject of dispute. Linnæus classed them with the _Passeres;_ Buffon, Pennant, and Latham arrange them as an order by themselves; while Cuvier and others place them in the category of Gallinaceous Birds. The settlement of this question is, indeed, a matter of considerable difficulty, as the habits of the entire race are in many respects very peculiar. Like the Passerine Birds, they associate in pairs during the nuptial season, work together in the construction of their nest, and materially assist in the incubation of their eggs and the care of their progeny, which latter, blind and helpless when they are first hatched, are fed in the nest that forms their cradle, and which they never quit until fully fledged; indeed, for some time afterwards they are unable to supply their own wants, and depend entirely upon the assistance of their parents. The features in which they differ from the Passerine race are, however, equally well marked; these consist in their manner of drinking and of administering food to their young family, in the singularity of their caresses, in the nature of their plumage, and in their vocal capabilities. They neither sing nor utter any cry; their only voice in the adult state consists of a full, rolling sound, generally designated by the term "cooing." Other dissimilarities separate them from the Gallinaceous races, with which they have little in common, either in their instincts, their manner of life, or their mode of pairing. The _Gallinæ_ are almost all of them polygamists, and the females, by laying numerous eggs, produce a covey at a single brood. Moreover, in temperate
