The trees u]M>n whirh the ruterpiUars of thesi- moths feed art- ii^iirrd in the manner 

 repres«"nt»tl in the foregoing .sketeh ; and though few iK-rsons are so i>atriotic as to gi\c 

 their srrvices to the public for the purjxjs*" of destroying noxious inserts, murh private 

 l>rn<-tlt would accrue fnmj the extertuinatioii of thes«- fon-st caterpillars. To this end, our 

 s|H-cinl friends the birds come in aid, and rid us of thousnn<ls of them : the cuckoo, cat- 

 blnl, n>bln, Jay, and many others fe<-d upon them, and thus diminish their numU-ni very 

 materially. The murderous gun sliould therefore never l>c }M)int(>d at birds who make It 

 their busim>ss to .servo us so efl'ectjuilly, esiHH-ially as we si-em little dlsi»osod to do any 

 thing this way for ourselves ; and even w<re the disjM.sition not lacking on our i«art, the 

 birds are certainly in'tter adapteil to <Io the work, and, no doubt, if spared by the fowler, 

 would l>c comiK'tent, from their coiise«|uent increus«' of nunilx-rs, to hold the increase of 

 InM'cts .so much in check as to save us fn>m serious danger fn'm that source. Indet-d any 

 man has a |H'rfect right to prevent the destruction of birds, on the same ground that he 

 has a right to protect himself from i>ersonal harm. 



The direct means for destroying the forest tent cater])illar are the .«amc as required In 

 the case of the ('. amrricann, namely, ib sfruclion of the webs and their contents at the 

 proper time, that is, when the inhabitants arc at home.
