DISINFECTION OF STABLES. 259 



(2) harmless to the occupants of the stable ; (3) and free from 

 disagreeable odour. Boiling water is a safe, efficient, and 

 readily procurable disinfectant. Creolin, of which Jay's Fluid 

 is a good form, and fairly pure carbolic acid serve this purpose 

 in an admirable manner, when diluted with about 20 times 

 their bulk of water. Crude carbolic acid is very cheap, but it 

 dissolves only sparingly in water, which is a drawback that can 

 be removed by mixing it with 4 times its volume of glycerine. 

 A solution of sulphate of iron (the impure kind will do) dis- 

 solved in a gallon of water makes a capital disinfectant, and 

 fixes ammonia by converting it into the sulphate. Carbolized 

 sawdust is very useful as a purifying agent, for sprinkling in 

 stables as may be required. It can be prepared by taking a 

 solution of equal quantities of crude carbolic acid and water, 

 and adding as much sawdust as will soak up the fluid. 

 Powdered gypsum (sulphate of lime) sprinkled over dung, 

 urine, and contaminated litter, absorbs the evolved ammonia 

 and thus, not only helps to keep the air of the stable pure, but 

 also retains the valuable ammonia for manurial purposes.
