PROCEEDINGS OF THE THIRD ENTOMOLOGICAL MEETING 



Does not the variety of wood make a difference 1 



Certainly it does, and therefore we have tried several different kinds. 



Do you think there is some difference when the wood is buried 

 entirely underground and when part of it is underground and another 

 part of it outside ? 



Certainly ; the part underground is attacked first. 



Did you try hot creosote under pressure ? 



No ; we have no pressure plant. Certainly, the more you can get 

 into the wood, the better. Creosote seems to be the best preservative 

 but cannot well be used for indoor purposes ; for outdoor use it is good 

 and well worth using where durability is desired. 



I have heard, although I have not tried it myself, that corrosive 

 sublimate, mixed with mortar and spread in a layer when the founda- 

 tions of a house are at a certain height, is useful in keeping off white- 

 ants. Have you tried it ? 



No. 



In some places they use arsenic mixed vvnth mortar and lay a layer 

 of it in the basement. 



Have you tried the White-ant machine in exterminating them from 

 a building ? I once had great trouble from termites in a godown. They 

 came out in numbers from the floor and attacked the boxes. I removed 

 the bricks from the floor and, by means of a wire, cleared the hole through 

 wliich the white ants were coming up. I then put the nozzle of the 

 machine into the hole and fumigated. It was very successful. 



I have used the machine successfully in a bungalow, but it is generally 

 necessary to break a hole into the galleries with a crow-bar. When 

 termites come up through the floors of the bungalows at Pusa, I generally 

 paint the place with crude creosote and that keeps them down for a 

 long time afterwards.
