the wings where the temperature is warm; but 

 they may be found on any part of the body and 

 at all seasons of the year, but are most common 

 in the hottest months of the year, July and Au- 

 gust. During these months conditions are more 

 favorable for their propagation. 



Dealing with Louse Infestation 



A time-honored and very effective method of 

 treating young chicks for lice is to grease the head 

 and neck, under the wings and around vent. Blue 

 ointment, lard and sulphur, salt and butter, and 

 various other greases are used, but none is more 

 effective than lard alone, which, although tedious 

 to apply, is justified by the excellence of the re- 

 sults obtained from its application. 



Older chickens may be either dusted with insect 

 powder or dipped in a preparation for destroying 

 the parasites as we dip larger animals. A dust- 

 ing powder composed of equal parts of pyreth- 

 rum and sulphur is an excellent one for ridding 

 birds of lice ; tobacco dust, which may usually be 

 secured at any tobacco factory, may be added 

 to the combination and perhaps will increase its 

 efficiency. This powder should also be sprinkled 

 in the dusting places of the infested chickens. 

 Dusting places should always be provided. 



An insect powder gun is needed for dusting 

 the birds. This may be secured at almost any 

 drug store. 



If it is the wish to dip the birds, prepare a fiv&- 

 per cent solution of creolin, or the same strength 

 of either zenoleum or kreso dip.
