grains of Bismuth mixed with dough and make into a 

 small pill. Give one every six hours. 



When in addition to the above symptoms a bloody dis- 

 charge is present, give six drops of Tincture of Catechu 

 every four hours. Warm mashes made of bran or oat- 

 meal are very nourishing and soothing to the intestinal 

 canal. 



DIPHTHERITIC ROUP 



(Diphtheria) 



Cause: Due to a specific germ. The disease is very 

 contagious and is communicated by direct contact. Great 

 care should be exercised, therefore, when showing or 

 buying birds. Any new birds to be added to the flock 

 should be kept in separate pens for a week or two to 

 make sure they are in good condition. 



Symptoms: The first symptoms are similar ^to those 

 of catarrh or cold. A clear, watery liquid escapes from 

 the eyes and nostrils, the head is drawn in toward the 

 body, the feathers appear rough, the breathing fast, the 

 temperature rises from three to five degrees above nor- 

 mal. The bird walks about as if blind, sneezing, swal- 

 lowing with difficulty, and showing signs of great weak- 

 ness. If the mouth is opened small white spots or ele- 

 vations will be seen on the back of the tongue. There 

 may be diarrhoea of a green or yellow color. As the dis- 

 ease progresses the discharge from the nose and eyes 

 becomes thick and stringy, obstructing the air passages 

 and gathering in large quantities between the eyelids. 

 The mouth, throat and tongue are very much inflamed 

 and swollen and in most cases it is impossible for the 

 bird to make a sound. Recovery is doubtful after the 

 disease has reached this stage. 



Treatment : Isolate the affiected birds in some clean, 

 warm, light, well ventilated quarters, excluding drafts. 

 Dissolve thirty grains of Chlorate of Potash in one ounce 

 of water and one ounce of Glycerine, and to the average
