INSECTS INJUEIOUS TO THE CKANBBEEY. 115 



worms of the second brood nearly full grown upon one 

 bog, while upon another, several miles away, the millers 

 were just laying their eggs for the second brood. 



"Water is, and probably always will be, the most ef- 

 fective agent in destroying this insect. Those that have 

 this convenient will find it best, I think, to flow their bogs 

 once or 'twice between the 10th of May and the 7th of 

 June — ^that is, if they let off the water early in the spring. 

 If they keep on the water until the first of June, it would 

 be well to flow two or three times during the month. 



I think it will be difiicult to find anything that can be 

 readily applied to destroy these insects in their larva, or 

 worm state. They live so sheltered within the leaves that 

 they have drawn together, that it is almost impossible to 

 reach them all, except with water. 



When they have spun their cocoons, and have been 

 changed to chrysalides, I think it doubtful if we can reach 

 them with anything. 



I hope that, in time, we shall find some way to entrap 

 the millers and destroy them ; or that something will be 

 found that will make the vines oflfensive, and drive them 

 away. 



Knowing that some moths were attracted by a mixture 

 of molasses and water, I experimented with that, and 

 found that it did uot attract this' miller. I have had no 

 opportunity to test fires, but from what I can learn from 

 others, I think that it is an uncertain remedy, at least. 



Many of these millers might be destroyed by Catching 

 them in a hand-net of muslin, and crushing them. On a 

 large bog, this would be tedious ; but on a small bog, one 

 or two persons could soon catch most of the millers after 

 a little practice in handling the net, going over the vines 

 about sunset. 



Sawdust, or old rags that have been soaked in kerosene, 

 or something else offensive- to insects, if scattered about
