CRANBERRIES — INSECT PESTS. 179 



flowing, the runners will not cover tlie ground, and you will 

 have a good deal of trouble from weeds. There are various 

 kinds of weeds that it is necessary should be killed by flood- 

 ing. The weeding gives occasion for a great deal of hard 

 labor. 



I do not know anything scientifically about the insects, 

 neither do my neighbors. We are hoping that the scientific 

 people will get hold of some valuable information in regard 

 to them. I have been very much interested indeed in the 

 collection of facts that have been brought together from va- 

 rious places and presented here by our young friend from 

 Amherst. We practical people find that there are about 

 three periods of attack by these worms. The first settlers 

 come along the latter part of May and continue into June ; 

 then, after an interval of about a month, we have another at- 

 tack ; and after an interval of another month, we have a third 

 attack. The first and second attacks are upon the leaves 

 and the stalks, and the last attack is on the berries. Some of 

 the people, not being possessed of a great deal of scientific 

 information, in consequence of the regularity of these inter- 

 vals have an idea that all the mischief is done by difierent 

 forms of the same insect ; the slight diflTerences in appearance 

 and mode of action they refer to the law of progress, in the 

 difi*erent stages of development, and perhaps they think they 

 are referable also to the amount and kind of nourishment 

 that is furnished these different sets of the same insects by 

 nature, as they come on. I presume it is not so, but they 

 have some such idea, and a good many intelligent people 

 hold that opinion^ 



These worms are fought with water, letting the water on 

 early and holding it on, and as it covers the bog over, where it 

 is warm and the sun shines clearly, this insect will be hatched 

 out and float on the surface, and be swept away by the wind. 

 Where the water is deeper and colder, and in places where, 

 perhaps, the sun has not such free access, there the water 

 does not seem to promote the hatching of the eggs, and they 

 will stay there, and the whole thing be checked by the water 

 itself which is let on to destroy them. Usually, after the 

 water is let on, the sun warms them up, and they will hatch 

 out then. One lesson we have been taught is, to have our
