Control. C'ultixatitiii as late in thv fall ;in(l as earl\- in the 

 si)rini;' as ])ractical)k' cluse to the stems of the berries will disturb 

 their hibernating" c|narters, and by direct injury or exposing;' them 

 to changes of winter temperatures many will be killed. Spraying" 

 the canes in the spring", \yhen the ^•olmg plants are about six inches 

 high, with arsenate of lead, two pounds of the ])owder to fifty 

 gallons of water \yill be very etfectixe. These ])rec;iutions, with no 

 neglected canes in the immediate \icinit}" will control the insect. 



Weed Insects. 



In dtu" studies up to this time about twenty of our common 

 Aveeds ha\e yielded thirt_\' ditterent species of insects. .Sonie of 

 these insects ha\e been so abundant that the weed was not allowed 

 to spread in that locality. This is a benefit that such insects may 

 bestow. ( )n the other hand, some weeds liarbor insects which in 

 turn attack our cultixated crojJS. Sometimes again, a weed insect 

 ma}- api)ear cpiite harmless excejjt to the weed, but if a particular 

 crop ])erhaps of some closel\" related culti\ated form were grenvn 

 near it, the insect ma}- attack the croj) in preference. Such being; 

 the case, it is \-er}- imi)ortant to know- as much as jio^silde concern- 

 ing" weed insects and thus lie ])rei)ared for what tlie future may 

 brinsj".
