All cracks and comers of an infested camp were wa^ed with a 

 3 per cent solution of cresol soap and were then filled up. The 

 building with a floor space of 450 meters was fumigated with 

 75 kilos of stdphur burned in 16 sulphiu* stoves, the burning being

Depediculization in an army should be on a unit basis or it 

 amounts to comparatively Uttle. because reinfestation from occa- 

 sional carriers or adjacent verminous commands is easy and usually 

 rapid. Treatment with na{^thalene or na|Athalene compounds is 

 one of the simplest and more effective methods, especially in the 

 field. The most satisfactory solution of this problem is found in 

 adequate badiing facilities so arranged in case there are vermin 

 present that the men strip in one room, cleanse themselves liioroughly 

 in a bathroom and emerge at the other end where they receive 

 clean clothes or at least those which have been freed of vermin by 

 heating (ironing, dry heat or steam). The essential in this process 

 is an arrangement which will insure against reinfestation after the 

 bath :.r. i :-. _ r • :: for treating the clothes as rapidly as the men
