INTRODUCTION 
whole process of skinning should take only from two to four min¬ 
utes. 
As soon as the skin is turned back, the feathers should be smoothed 
and arranged, the eyelids adjusted, and the edges of the opening of 
the skin laid together before it is put down. 
Stuffing. — For the sparrow, take a short thick piece of cotton — 
tow for large birds —that will make a form the size of the body 
that has been removed from the skin, and press it firmly together 
with the fibers all one way. To fill the skull and make a firm neck, 
pinch one end of the cotton flat and double it over twice, holding it 
firmly after each time between the thumb and finger of the left 
hand. Then catch the hard compact point of cotton between the 
forceps in a position to hold it securely and push it into the bird 
skin, forcing the point up through the neck and base of the skull, 
catching it again with the left thumb and finger in the mouth of 
the bird. Loosen and draw out the forceps, but hold the cotton in 
the mouth until the skin is drawn back and adjusted over the 
stuffing, and superfluous bits of cotton removed or tucked in. 
Then draw together the edges of the skin and catch with a couple 
of stitches. When the wings have been put in place under the 
feathers at the sides, and the feathers properly arranged and 
smoothed, the skin is ready to be labeled and wrapped in a thin 
film of cotton. Then the bill can be tied shut with a thread and 
the bird laid away to dry. 
A beginner’s skins are often greatly distorted, and only practice 
can teach the correct amount of cotton to use and its proper form 
and proportions. The best way is to keep in mind the size and 
form of the bird’s body, and try to reproduce them. Be careful not 
to make bulging or weak necks. Leave each skin straight and 
symmetrical when put away to dry, and each feather back in its 
original place. 
Labeling. — Skins should be fully labeled with locality, date, sex, 
number, and collector’s name, while such additional data as color of 
eyes, bill, feet, or any parts that fade, notes on breeding or locality 
where taken, stomach contents, etc., can be placed on the back of 
the label or kept in a catalogue under the number of each specimen.

Sexing. — To determine the sex, cut through the side of the ab¬
