PHEASANTS IN COVERT AND AVIARY 



known as sarcoptes laevis, which exist at the base of the 

 feathers, causing the feathers to be shed or break off at 

 the surface of the epidermis ; the head and the upper part 

 of the neck are commonly affected, but the thighs, back, 

 etc., as well as neighbouring parts, readily become implicated, 

 whilst the trouble seldom affects the wings and the tail. One 

 bird will soon affect others, unless preventive measures 

 are adopted. It is sometimes mistaken for early or late 

 moulting in birds, but its infective nature serves to distin- 

 guish it from the normal process. The best treatment is 

 to arrest the affected parts with a liniment as per pre- 

 scription below : — 



Flowers of Sulphur . . . 2 oz. 



Linseed Oil ... ^ pint 



Mix and apply daily.
