PROGRESSIVE POULTRY CULTURE 133 



(ninety-eight parts water, two parts concentrated car- 

 bolic acid) will tend to keep the pests at a distance. An 

 emulsion for spraying may be made as follows: 



One pound of hard soap is cut into thin shavings and 

 dissolved in one gallon of water. Heat gradually until 

 it boils, then add one pint of crude carbolic acid. Force 

 this through a force-pump, directing the nozzle of tne 

 outlet pipe so that the stream strikes back into the 

 receptacle, thus churning the warm liquid until it be- 

 comes a creamy mass. On cooling the mixture becomes 

 jelly-like. This is kept as a stock emulsion. For use 

 take one pint of the stock, add fourteen pints of water, 

 mix well and apply thoroughly with a spraying pump or 

 a brush. 



Some poultrymen use crude petroleum, others ordi- 

 nary kerosene for applying to the poultry perches. In 

 either case the addition of one or two per cent, of strong 

 carbolic acid makes the liquid more effective. 



A kerosene emulsion may be used which is made as 

 follows: One-half pound of hard soap cut into thin 

 shavings is dissolved in six quarts of water, brought to 

 boiling and removed from the stove. While the liquid 

 is yet hot add eight quarts of kerosene. Churn the mix- 

 ture with a spray-pump until it changes to a soft butter- 

 like mass. Use one part of this stock liquid to nine parts 

 of water for applying with pump or brush. 



To render the kerosene emulsion still more offensive 

 to the vermin add one part of concentrated carbolic acid 

 to ninety-nine parts of the liquid before spraying. This 

 is both economical and effective. 



Creolin in two per cent, solution is excellent for use 

 in spraying. 



Many of the prepared liquid lice killers on the mar- 

 ket are excellent and may be bought in any quantity de- 

 sired. 



LICE. 



Body lice of several kinds are very prevalent on the 

 skin of fowls where the parts are covered by fluffy feath-
