the rump without loosening the feathers; but this difficulty 
will be overcome by using particular care while skinning the 
spot that is tender. Some birds also have tender skin on 
the breast, and in such cases it almost always adheres so 
closely to the flesh that it is necessary to cut it away; 
this operation is somewhat tedious, but it is better than 
to risk tearing the skin by pulling it. An example of this 
is sometimes seen in the Wood Duck. 
The best time to skin a bird is as soon as it is shot, 
when the muscles are relaxed, as the plumage is then in 
the best condition. In a short time the muscles become 
rigid, when it is extremely difficult to remove the skin ; 
but the muscles soon relax again, and then you must skin 
at once, as this is the first stage—or the state imme- 
diately preceding the first stage —- of decomposition. In 
very warm wether this rigidness of the muscles sel- 
dom occurs, then the bird rapidly decomposes. In warm 
weather, birds should be kept on ice until wanted ; for if 
a bird remains only an hour in a warm room, or in the 
sun, it will sometimes spoil, especially if the blow-flies 
are allowed access to it. There is a species of blow-fly 
that is viviparous; I have seen such a fly alight upon 
a fresh bird, and, after introducing her ovipositor into the 
month of the specimen, exude an immense number of liv- 
ing, thongh minute, maggots. These maggots spread over 
the skin in all directions, moistening it with their slimy 
bodies, and soon render the specimen unfit for use by 
loosening the feathers. 
It is difficult to remove the eggs of the common blow- 
fly when they are once placed upon the feathers. It is 
much better to prevent the flies from attacking specimens 
—which, if they are exposed during warm weather, they 
will do very quickly — by covering them, or placing them 
immediately upon ice.
