Col. T. Pickerini*-. in a letter to Mr. Lowell the same year and pul)- 

 lished in the same volume, stated that there were trees in New Hamp- 

 shire uninjured hy the borer, as well as in some of the Southern States; 

 that he had obsei-ved the stems of younj; trees in Washint^ton, D. C, 

 infested, while in 

 (reortjetowniD.C) 

 he saw lartj^e th ri f ty 

 trees uninjured; 

 and he concluded 

 that natural uTowth 

 in groves was much 

 less liable to injury 

 than transplanted 

 •growth. 



Fitch, wiitinii' in

 numbers of s]>eci- 

 mens were sent to 

 him year after year 

 from Indian Teni-

Schwarz {ls\H\) 

 observed that in 

 and around the 

 Di.striet of Columbia the insect lives in lare-e colonies, aH'ectinj^all trees 

 of small frr()V(>s. while lonj^- hillsides full of locust are not infested. 



K. S. Kcllo^jLT, i" his discussion of forest plant in*,'- in western Kansas, 

 says:" 



By locating plantation on pood gronml and giving it tirnt-claRs care, the trees will 

 reach fence-post size l)efore tlie liorers flo much <himage. They should th«-ii he cut 

 and utilized. The rapiil sprout growth will soon make a new crop. A stinii]) sprout 

 sometimes attains a height of 10 feet the tirst season. Hamlled in this manner, hlaek 

 locust can he prolitahly raised in many places where it is altogether inisuited for a 

 permanent tree. 



At i)resent horers are a menaee to l.jaek li.eust trees throughout western Kansas 

 and Nebraska, though there are oceiL-ioual lo( al areas that are uot affecte<l. They
