quarts of commercial cresol. The cresol will blend perfectly 

 with the soap solution and make a clear, dark brown fluid. The 

 resulting solution will mix in any proportion with water and 

 yield a clear solution. 



Cresol soap is an extremely powerful disinfectant. In the 

 Station poultry plant for general purposes of disinfecting the 

 houses, brooder houses, incubators, nests, and other wood work, 

 it should be used in a 3 per cent solution with water. Two or 3 

 tablespoons full of the cresol soap to each gallon of water will 

 make a satisfactory solution. This solution may be applied 

 through any kind of spray pump or with a brush. Being a clear 

 watery fluid it can be used in any spray pump without difficulty. 

 For disinfecting brooders or incubators which there is reason 

 to believe have been particularly liable to infection with 'the 

 germs of white diarrhea or other diseases the cresol may be 

 used in double the strength given above and applied with a 

 scrub brush in addition to the spray. 



B. Fresh Air and Light. — Too great stress cannot be laid on 

 the importance of plenty of fresh air in the poultry house if the 

 birds are to keep in good condition. And it must be remem- 

 bered in this connection that "fresh" air, and cold stagnant air 

 are two very different things. Too many of the types of curtain 

 front and so-called "fresh air" houses now in use are without 

 any provision other than an obliging southerly wind, to insure 

 the circulation or changing of air within the house. Even with 

 an open front house it is wise to provide for a circulation of 

 air in such way that direct drafts cannot strike the birds. This 

 applies not only to the housing of adult birds in laying houses, 

 but also to the case of young stock in colony houses on the 

 range. Further a circulation of fresh air under the hover in 

 artificial rearing is greatly to be desired and will have a marked 

 efifect on the health and vigor of the chicks. 



Not only should the poultry house be such as to furnish 

 plenty of fresh air, but it should also be light. The prime im- 

 portance of sunlight in sanitation is universally recognized by 

 medical authorities. Disease germs cannot stand prolonged 

 exposure to the direct rays of the sun. Sunlight is Nature's 

 great disinfectant. Its importance is no less in poultry than in 

 human sanitation. The following statement made some years 

 ago (1904.) by a writer signing himself "M" in Farm Poultry
