JNTS 



jrp or ants, spraying is unsatisfactory. Each nest must be 

 Ir dealt with separately. They may be killed by mixing 

 Paris-green and sugar and dropping around the holes. An 

 ingenious method suggested is to soak sponges in sugar 

 water and place them near the holes, occasionally throwing 

 the sponges into hot water. Carbon bisulphide is an effec- 

 tive poison. Inject it into the ant-hole with a common ma- 

 chine oiler with a long spout. A heavy gas is formed which 

 permeates the nests. Remember that this chemical is ex- 

 plosive. Potassium cyanide may be used effectively in the 

 same manner, and is cheaper. Dissolve one ounce of ninety- 

 eight per cent, potassium cyanide in one quart of water. 



MOLES 



71 /TOh^s are often a great nuisance on the golf course and 

 1 K/can be destroyed only by persistent trapping. As moles 

 pass obstacles by going around them rather than by digging 

 under, and as some species ordinarily work less than six 

 inches below the surface, they may sometimes be kept out 

 of small areas by sinking thin boards, edge down, just be- 

 low the surface. Traps should be set with care, and gloves 

 worn in the process as the animals have a keen sense of 

 smell. 



BROWN PATCH 



r TNTiL recently nearly every brown area appearing in a 

 C/ putting-green or fairway during periods of moist hot 



weather, was attributed to "sun-scald." Such patches of 



brown are often noticeable 



on the turf in early morning, 



givmg a smoky or cloudy 



appearance to the affected
