instructions and ordinary precautions taken, there was no danger of 

 their stock being poisoned, the natives withdiew their objections to 

 its use. It is interesting to note that although thousands of swarms 

 of voetgangers were destroyed in the native areas no known poisoning 

 case occurred. A particular word of praise is due to the locust officers 

 of the above-mentioned two districts, who did such good work under 

 such trying conditions. 



Damage to Crops. 



Due to the fact that (1) by the time the swarms that escaped 

 destruction reached the fiying stage, a large proportion of the crops 

 had ripened too far to be damaged by locusts, and (2) by means of 

 the intelligence system in vogue, it was possible to warn the farmers 

 that the flying swarms were going in their direction and that they 

 should reap their crops at the earliest possible moment, the devasta- 

 tion was not so serious as was anticipated.

 BeCHUAN ALAND PROTECTORATE. 



By arrangement with the Protectorate authorities, the Union 

 officers stationed along the Malopo River assisted with the destruction 

 of the yoetgangers in that portion of the Protectorate bordering on 

 Mafeking District. The Union officers worked 20 miles inland in the 

 Piotectorato and were instrumental in destroying 200 swarms in this 

 area . 



Farmk r s ' Circles . 



The farmers' circle system explained below is being adopted in 

 quite a large number of districts, and will, it is considered, be of 

 great assistance to the Department, in that it will ensure the co-opera- 

 tion of the farmers, without which no locust campaign can be success- 

 ful.

 prised of about twelve farms.
