Disinfection. — Disinfection shonld be constant 

 while this disease is on the premises. For this pur- 

 pose a solution may be made by mixing one pound of 

 carbolic acid with twenty -four pounds, or say twelve 

 quarts, of hot water. Or one pound of sulphuric acid 

 to fifty quarts of water may be used. The latter is 

 the cheapest but it is more dangerous to use. When 

 the sulphuric acid is purchased have the druggist 

 dilute it with twice its weight of w^ater. If thus 

 diluted it will not burn the flesh or clothing as severely 

 as when concentrated and there is little danger of an 

 explosion when it is further diluted. When diluting 

 it, always pour the acid very slowly into a compara- 

 tively large quantity of water, being careful that it 

 does not splash into the eyes, and remember that con- 

 siderable heat results. A wooden bucket is, therefore, 

 better than a glass bottle, and, on account of its cor- 

 rosive nature, metal vessels can only be used for the 

 most dilute solution. If carefully used with proper 

 precautions to prevent it flying into the face or eyes 

 ■ when diluting, sulphuric acid is the most satisfactory 

 disinfectant. If any gets upon the flesh, apply large 

 quantities of water at once, or it will burn very 

 deeply; if it reaches the clothing it causes discolora- 

 tion and soon destroys the fabric. It may be neutral- 

 ized with ammonia or a solution of baking soda. 

 With this digression concerning disinfectants we will 

 now return to the methods of disinfecting. If possi- 

 ble move the fowls to new runs and new houses when 

 cholera appears among them. Before they are moved,
