FORESTRY, 



[Report of] department of forestry, J. A. Febguson {Pennsylvania Sta. Rpt. 



1915, pp. 465, 4^6) ■ — A new willow holt was established during the year and 

 small plantings of several forest species were made. In tiie nursery seed beds, 

 seedlings of deep-rooted species such as red pine and Scotch pine demonstrated 

 their superiority as compared with shallow-rooted species such as European 

 larch and Norway spruce in surviving the dry summer of 1915. 



A test was made of 1-year-old black walnut seedlings, root-pruned and trans- 

 planted, as compared with seedlings allowed to grow for 2 years undisturbed. 

 Two hundred undisturbed seedlings made an average second year growth of 

 5.25 in. as compared with an average second year growth of 2 in. for 200 root- 

 pruned and transplanted seedlings. 



Two-year seedlings of lodgepole pine were exposed to the sun before planting 

 for lengths of time ranging from 2 up to 300 minutes. Exposures of over 10 

 minutes resulted in losses of from half to all of the seedlings as the time of 

 exposure increased. The amounts of damage for exposures of 10 minutes or 

 less are not conclusive. Of seedlings exposed for 2 minutes, 76 per cent were 

 alive on September 17; of seedlings exposed for 4 minutes, 93 per cent were 

 alive ; and of seedlings exposed for 10 minutes, 83 per cent were alive. 



Some new experiments and miscellaneous work being conducted by the de- 

 partment are briefly noted.
