PINE. TRUNK — PINE BLIGHT, 169 



I have never succeeded in discovering any winged individuals 

 of tliis species, and hence cannot decide with confidence as to its 

 genus. The one jointed feet indicate that it pertains to the Fttraily 

 CocciDa: of the Order Homoptera, and the facts in its history which 

 are above recited, leave but little doubt that it belongs to the ge- 

 nus Coccus as restricted in systematic works at the present day. 



By many the white pine is much esteemed as a shade tree* 

 around dwellings, particularly upon their north and west sides, 

 for breaking olf the winds of our severe northern winters. It is 

 also highly prized as an ornamental tree in those sections of our 

 country where it does not grow naturally. Hence whatever re- 

 tards the growth and impairs the health of these cultivated trees, 

 becomes a matter of interest. I have repeatedly noticed this 

 blight upon transplanted trees, but have never observed it upon 

 trees growing in their native situations. 



There is every probability that scrubbing the affected parts of 

 a tree with soyp-suds, will prove a sovereign remedy for this as 

 it is known to be for other species of lice. And this remedy will 

 be of easier application here, than in most other cases where it is 

 the smalhtwigs of trees which are infested with these vermin. 

 As this blight is located upon the trunks, chiefly of young trees, 

 it can be readily reached by the scrub-broom. Th« remedy is so 

 simple and so easy of application, that no one should suffer the 

 young pines in his yards to dwindle and become stinted and sick- 

 ly from this cause.
