pouring a large dose of the solution down the fowl's throat three 

 or four times a day. Castor oil and turpentine and warm water 

 are two other highly recommended remedies. 



Mange (Scabies) .^This is caused by mites which live at the 

 base of the feathers, where they bite the skin and cause intense 

 itching. It is quickly spread throughout the flock, and while 

 the general health of the birds does not suffer greatly, still the 

 trouble is discomforting, and if allowed to continue the birds 

 will lose flesh and become unproductive. Moreover, as the mites 

 spread the plumage is destroyed until the birds are almost naked. 



Apply to the affected parts, and for some distance around 

 them, an ointment made by mixing i part flowers of sulphur 

 with 4 parts of vaseline or lard. Carbolated vaseline may be 

 used, too, and if it is mixed at home, use i part carbolic acid to 

 50 parts of vaseline. It is sometimes beneficial to wash the irri- 

 tated surfaces with a solution of creolin or some other disinfectant.

 chronic form of roup, are generally the aftermath of such ail- 

 ments as colds. 



The first symptoms of roup are similar to those of a cold, 

 except in the former there are more fever, dullness and prostration. 

 There is sneezing, accompanied by a watery discharge from the 

 eyes and nostrils. Later this discharge becomes thick and ob- 

 structs the breathing, and as the inflammation, which begins in 

 the nasal passages, extends to the eyes and the spaces below the 

 eyeballs, the fevered condition hardens the secretions into a 

 cheesy matter, which accumulates in the tissues of the head, 

 causing the eyes or other parts of the face to bulge. This cheesy 

 matter has a very offensive smell, sometimes' it obstructs the
