Of course a detail cost keeping system 

 will be necessary. 



Those of us who look forward to 

 some such system as outlined above 

 must realize that it cannot be put into 

 operation at once nor will it be per- 

 fected in ten or twenty years. 



The man we want must get the for- 

 estry point of view and the funda- 

 mental principles of his work in some 

 undergraduate school or some ranger 

 school where the course is shaped for 

 him, and his woods training under the 

 best woods bosses we now have. Some 

 of the brightest young fellows in our 

 camps today will probably make the 

 best men, if they will get the necessary 

 education. 



HICKORY BARK BORER

IDEAL SPRUCE LEFT FOR SEED PRODUC- 

 TION AND GROWTH. NOTE SYMMETRI- 

 CAL, THRIFTY TOP, ALSO THE OTHER 

 SPRUCE LEFT AFTER LUMBERING BY 



pernicious hickory bark borer 

 has already destroyed thousands 

 of magnificent trees in Central 

 and Eastern Xew York. The inner 

 bark of many of the affected trees con- 

 tains stout, white grubs, about one- 

 quarter of an inch long, which will de- 

 velop into beetles from the last of June 

 to the last of July. These insects, in 

 the natural order of events, will con- 

 tinue their nefarious work, and numer- 

 ous other trees will succumb. 



It is extremely important that all in- 

 fested hickories, especially those show- 

 ing only particles of brown or white 

 sawdust in the crevices of the bark and 

 the characteristic working of the in- 

 sects within, should be located and the 

 infested bark destroyed before the end 

 of May. Such trees are more danger- 

 ous to the welfare of adjacent living 

 hickories than others, which may be 

 fairly peppered with the numerous exit 

 holes, appearing as though they had 

 been made with No. 8 buckshot. The 

 borings of this pest in the inner bark 

 are very characteristic, there being 

 longitudinal galleries 1 to l l / 2 inches 

 long, about one-eighth of an inch in 

 diameter, and with numerous fine. 

 transverse galleries arising therefrom 

 and gradually spreading out somewhat 

 fan-shaped. 



There is only one thing to do in the 

 case of a serious infection, such as that 

 indicated by dying trees or branches. 

 All badly infested trees or portions of 

 trees should be cut and the bark at least 

 burned before the following June, in 

 order to prevent the grubs from ma- 

 turing and changing to beetles, which 

 may continue the work in previously 

 uninfested trees. It is especially desir- 

 able to locate the hickories which have 

 died wholly or in part the last sum- 

 mer, because they contain living grubs. 

 General cooperation over an extended 

 area in the cutting out of infested trees 

 and burning of the bark, as indicated, 

 will do much to check this nefarious 

 pest. It is essential to destroy the 

 grubs in the bark by fire or by sub- 

 mersion in water before the date given. 

 This does not make it impossible to 

 utilize the timber and most of the fire-
