advanced, the males became very pugnacious, and great contests took place between themselves, as well as with the Pigeons and the young poultry that occasionally intruded on their domicile. In May the hens commenced laying, both in one nest, and the eggs were hatched under a Domestic Hen." Dr. Bachmann was prevented carrying out his experiments further, but other observers have been more fortunate, and have without trouble reared many of these delicate birds in closed rooms. Their great fertility is very favourable to their increase, wherever it is wished that they should be naturalised. Several attempts have been made to introduce this species into England, and from time to time specimens have been shot in different parts of the country. The American Partridge is easily caught by means of snares and traps of various descriptions. Many are shot, but they are most frequently netted in the following manner:--A number of persons, furnished with a net, ride along the fences and thickets where the birds resort, one of the party simulating the call of the bird, which is soon answered by a covey; the party approach in an apparently careless manner to ascertain the position and number of the others; and then a horseman furnished with a net gallops a hundred yards in advance, and places it so that his companions can drive the Partridges into it. In this manner fifteen or twenty Partridges may be caught at one driving, but a pair out of each flock usually receive their liberty for fear that the breed should be destroyed. * * * * * The CALIFORNIAN PARTRIDGE (_Lophortyx Californianus_) and GAMBEL'S PARTRIDGE (_Lophortyx Gambelii_) represent an American group principally remarkable for the crest that adorns their head. These birds have a powerful body, short neck, and moderately large head. The short arched wing is rounded at its extremity, and has its fourth or fifth quills longer than the rest. The tail, composed of twelve feathers, is short and remarkably graduated; the beak is short, strong, and much arched at its culmen; the foot is of medium height, and the thick plumage compact and glossy. At the top of the head rises a crest, formed occasionally of from two to ten, but generally of from four to six feathers; these are slender at the roots, becoming gradually broader towards the tips, which incline forward, and have somewhat the form of a sickle. This crest is much developed in the males. The coloration of the plumage, though by no means gorgeous, is both beautiful and brilliant. THE CALIFORNIAN PARTRIDGE.
