There are two other diseases which many claim are 

 related to roup — chicken pox, or sore head, and canker. 

 Chicken pox affects the unfeathered parts of the head. It 

 first appears as a blister; later, a dark, hard scab forms. 

 Canker consists of sore spots in the mouth. These spots are 

 often covered with a thick coat or yellowish scab. 



ISTo one has been able to show exactly what the relation 

 between these three diseases is, but it is certain, at least, that 

 they respond to the same treatment. Creolin or zenoleum is 

 a good remedy when applied directly to the affected parts. 

 As a system treatment, the following often proves effective : 



Magnesivim sulphate i. ■ 10 oz. 



MagTiesium oxide 1 oz. 



Sulphate of iron 2 oz. 



Ground ginger 2 oz. 



Sulphur 3 oz. 



Give 1 teaspoonful to 12 fowls in moist mash each morning for 

 3 mornings then discontinue till needed. For severe cases douhle 

 the dose. 



Another common disease of poultry is gapes. This is 

 caused by a small worm which fastens itself to the inside of 

 the windpipe of a fowl, and lives by sucking the bird's blood. 

 A fowl aiSicted with gapes stands in a drooping position, fre- 

 quently gaping and showing signs of irritation in the throat.
