THE CABBAGE MOTH. 161 



Before applying the tar-water or the emulsion, as the 

 case may be, care must be taken that the plants are not 

 previously disturbed, otherwise many of the grubs may 

 temporarily absent themselves only to crawl up the stems 

 again after the danger has passed. 



Give the plants a thorough watering (the rose to do the 

 work properly must be a fine one) ; spraying is of course 

 the best system, and after having gone through the beds, 

 water with the same material a narrow space around the 

 beds, as the larvae which have fallen to the ground will be 

 on the look-out for a chance to escape, but will seldom 

 attempt to cross the line of tar-impregnated surface of 

 soil, where they will soon die. 



Before planting, the bundles of young plants should be 

 submerged in a decoction of weak tobacco-water, to which 

 a little soft-soap and tar water could with advantage 

 be added. In this they should remain for fully an hour, 

 when they could be dipped into clean water, and planted 

 out into the positions in which they are to remain until 

 required for market. 



Our plants may now be supposed to have been set out 

 where they are to remain, and an occasional spraying 

 would be the best, and in the end cheapest, for which 

 purpose the Strawsonizer, or the admirable machine 

 invented by the chemist to this department, Mr. A. N. 

 Pearson, could be used. I feel sure that if such measures 

 as these were adopted, the losses occasioned by the 

 cabbage-worm pest in Victoria would be greatly reduced. 



In cabbages, we know by the experience of some of 

 our old and successful growers, there is a small fortune. 

 A knowledge of this, therefore, should make us the more 

 determined to adopt any reasonable precautions that can 

 be easily carried out, taking the expense, of com-se, into 

 serious consideration. 



The cabbage aphis also cannot stand the smell of tar, 

 so we can fight these two destructive pests at the same 

 time and by almost the same methods. 



When the cabbages are large, too large for the spraying 

 material to reach the caterpillars or cocoons, which are
