Some pronounce this bird the unmixed and immediate descendant of the Gray-leg; while others assert that it is only the common domestic, enlarged by early hatching, very liberal feeding during youth, fine climate, and, perhaps, by age, and style them grenadier individuals of the domestic goose--nothing more. THE WHITE-FRONTED GOOSE. In its wild state, the White-fronted or Laughing goose is twenty-seven inches long, and found in great numbers in Europe and in the North American Fur countries, but rare along our coasts. When domesticated, it belongs to the class of birds which are restrained from resuming their original wild habits more by the influence of local and personal attachment than from any love which they seem to have for the comforts of domestication; which may be trusted with their entire liberty, or nearly so, but require an eye to be kept on them from time to time, lest they stray away and assume an independent condition. The white-fronted goose well deserves the patronage of those who have even a small piece of grass. The first impression of every one, upon seeing this species in confinement, would be that it could not be trusted with liberty; and the sight of it exercising its wings at its first escape would make its owner despair of recovering it. This is not, however, the case. By no great amount of care and attention, they will manifest such a degree of confidence and attachment as to remove all hesitation as to the future; and they may be regarded as patterns of all that is valuable in anserine nature--gentle, affectionate, cheerful, hardy, useful, and self-dependent. The gander is an attentive parent, but not a faithful spouse. The eggs are smaller than those of the common goose, pure white, and of a very long oval; the shell is also thinner than in, most others; the flesh is excellent. * * * * * Having completed the enumeration and description of the varieties of poultry, it will, perhaps, be appropriate to give some account, before proceeding to the next general division of the subject, of the structure, or anatomy, so to speak, of THE EGG. In a laying hen may be found, upon opening the body, what is called the _ovarium_--a cluster of rudimental eggs, of different sizes, from very minute points up to shapes of easily-distinguished forms. These rudimental eggs have as yet no shell or white, these being exhibited in a different stage of development; but consist wholly of _yolk_, on the surface of which the germ of the future chicken lies. The yolk and the germ are enveloped by a very thin membrane. When the rudimental egg, still attached to the ovarium, becomes longer and larger, and arrives at a certain size, either its own weight, or some other efficient cause, detaches it from the cluster, and makes it fall into a sort of funnel, leading to a pipe, which is termed the _oviduct_.
