Parasites Affecting Poultry and Methods of Extermination 139 



pour it very gently into the crock of linseed oil, stirring it constantly 

 all the time. Keep stirring for from 20 to 30 minutes until a smooth, 

 thick soft soap is formed. Then stir in the commercial cresol, which will 

 dilute the soapy mixture into a clear, reddish brown liquid. This is 

 a very powerful disinfectant and only three per cent of it is needed 

 to destroy all insect life. This makes a cheap, good disinfectant that 

 one can afford to use in quantity. No tick, flea, mite, or louse that this 

 gets near will ever live to tell the story. It can be diluted and used 

 to spray hogs and cattle in the spring time, when they get vermin on 

 them. 



The Sulphuric Acid Spray. — This disinfectant is more as a cleanser 

 of ground than for vermin, wherever there are sick poultry, roup, 

 diarrhoea, or any contageous or infectious disease, the sulphuric acid 

 spray will be found useful. Materials: Sulphuric acid (50 per cent sol.) 

 16 ounces; water, 6 gallons. 



Directions: Have the water in a barrel or large wooden pail. 

 Add the diluted sulphuric acid slowly, being careful not to splash any 

 on the flesh or clothing, as it burns either one. It is best to mix 

 just what you intend to use at once, and put on an old suit of clothes 

 to work in. Woolleni will not burn so readily as cotton goods. 

 Carefully made and used, there is no better disinfectant, but it must 

 be used carefully and children kept away from it altogether. 



Whitewash For Spraying.— Pour boiling water over sufficient quick- 

 lime to ser\'e your purpose, cover over and let stand one hour, add 

 salt at the rate of one cupful to the gallon and to each gallon one 

 ounce of crude creosote. Strain through a burlap if wanted for spray 

 pump. If a little tallow is added to the lime wash, it will not peel 

 off so readily and will stand the rain better. 



Creolin Spray For Brooder Houses, Brooders, Etc. — Creolin solu- 

 tion may be made any strength to suit the purpose it is wanted for, 

 and it is absolutely safe. It is far the best to use where small chicks 

 are to be housed. 



Always get "Pearson" Creolin, eight ounces to six quarts of water 

 makes a very strong solution that will kill any insect or vermin it 

 comes in contact with, and yet to chicks or persons is practically non- 

 poisonous. It can be painted on woodwork, or on floors of brooder 

 houses or sprayed. When dry it is colorless, and there is nothing 

 to be seen, yet as a germ destroyer it cannot be excelled. Can be 

 used to spray brooder, incubator or anywhere about the house, barn 

 or poultry buildings. 



A Good Roost Paint. — By painting the roosts, walls, etc., of 

 poultry houses with this liquid louse killer, lice will never get a footing 

 in the building. The fumes from it are too strong to suit mites or 

 Other insects. One gallon crude oil, one pint crude carbolic acid,
