escaping, as in No. I, in preference to going on to the untreated 

 plants. A few dead slugs were seen clinging to the branches. 



After 28 hours there was a slight increase in the number of 

 ■dead. The same semi-stupor apparent in the corresponding 

 observation in No. I was here also evident. 



After 52 hours a few more bugs had left the treated and 

 •crossed over to the.undusted plants. 



After 68 hours only a few bugs were remaining and these were 

 eating heartily on the basal leaves, the stupor apparently having 

 passed away. 



Nothing of importance was observed in the following three 

 days at the end of which time the experiment was discontinued. 



THIRD EXPERIMENT. 



Statemeni of Conditions. The four plants which were taken 

 In this group were all first thoroughly wet with water, then liber- 

 all) sprinkled with Bug Death. The operation was repeated, 

 first wetting and then sprinkling, until the leaves were evenly 

 covered with Bug Death, and there was no dust apparent as such. 

 The plants were next freely covered with slugs. 



Results : As in experiments Nos. i and 2 the slugs soon 

 sought the underside of the leaves. 



After 6 hours a few of the slugs were noticed making their 

 escape from under the netting and four were found dead under 

 the plants. 



After 22 hours there were a few more dead under the plants. 

 There was a general leaving of the upper leaves for the basal. 

 Almost half of the insects were driven as in previous experiments. 



After 28 hours no marked change was noticed. A few more 

 bugs had gone to the base of the leaves, and the semi-stupified 

 condition was becoming evident. 



After 52 hours there were only a few slugs left on the vines, 

 the others apparently have been driven away. 



After 68 hours the few remaining bugs were feeding freely 

 on the basal leaves. The semi-stupor was not apparent. 



During next three days no change was observed and the 

 experiment was discontinued.
