The poultry keeper will find that spraying the quarters once 

 a month with a one per cent solution of carbolic acid, to 

 destroy the lice and disease germs, will make a vast differ- 

 ence with the measure of his success. 



Question. Is one per cent of carbolic acid sufficient to 

 spray for lice? 



Professor Brigham. Yes, I think it is. If 3'ou are not 

 satisfied, use three per cent ; if .that does not meet with 

 success, use five per cent. 



Question. How does that compare with kerosene? 



Professor Brigham. Kerosene kills them. The louse 

 breathes through its pores. If you can get these substances 

 into contact with the lice, their breathing wdll be stopped. 

 I suppose that carbolic acid is the best disinfectant and deo- 

 dorizer for killing germs that we have. I would use the 

 carbolic acid once a month the year round, if possible. 



Question. Have you had any experience with carbo- 

 linoleum? 



Professor Brigham. Yes, I think it is good ; all tar prod- 

 ucts are good. I do not think, however, it is wise to pay 

 a large price for it, when the real thing that kills is carbolic 

 acid. It is all right sometimes to buy these things and use 

 them. In using carbolic acid, you can put one part with 

 ninety-nine parts of water and apply it with a broom or 

 cloth, being careful to keep it from your eyes and clothe^. 

 You want to apply it in such a manner that it will come in 

 contact with the lice and mites. 



Question. Would you reconmiend using air-slaked lime ? 



Professor Brigham. I would not use it, because it would 

 get in the throats of the fowls, and bring on bronchitis and 

 other troubles. If you are going to use it, it better be as 

 whitewash. 



Question. I think the lecturer failed to recommend 

 decidedly the Brown Leghorns. Why do they not compare 

 well with the White Leghorns and the other breeds you 

 spoke of ? 



Professor Brigham. They are all right : I have had them. 

 If you are going to put them on the market as dressed fowls, 

 the Avhite pin-feathers will show less than the dark ones. 

 It is not so nuich the matter of breeds, as of family and
