COLORADO POTATO-BEETLE. 



The bugs are disposed of by burying them in perpendicular holes, 

 covering them with a foot of earth and stamping it down. At first 

 Mr. Squires thought it necessary to kill the bugs, and drenched them 

 with strong lime-water, but he found this to be unnecessary. The bugs 

 thus buried, en masse, soon perish 



We have not space for comments, but every reader can draw his 

 own conclusions. The machine could, no doubt, be improved by ex- 

 perience and ingenuity. The one which we saw was a rough and 

 cheap, but efl'ective piece of work ; but these are the very qualities 

 which make it available to the common farmer, and which have ap- 

 peared to us to justify this somewhat extended notice of it. If this 

 machine proves as successful in the hands of others as it did in those 

 of the inventor, it will supply an important need in potato culture upon 

 a large scale. 



The Paris green will still have to be used whilst the vines are small, 

 or until they are four or five inches high, but at this time its applica- 

 tion is very easy, and it requires comparatively little of the poisonous 

 material ; and we cannot too often reiterate that experience has shown 

 that the Paris green may be, and ought to be very largely diluted, 

 that is to say, with about twenty times its bulk of flour or lime, or 

 other inert powder.
