BOTAXICAL SUKYEV— SUGAR GROVE REGION 301 



The best and most profitable method of accomplishing reforesta- 

 tion under the varied conditions presented are of course nuitters to be 

 determined by experiment. But it cannot be doubted that tree plant- 

 ing would be profitable on much land that is now going utterly to 

 waste. White pine {Pin us slrohus) has been recommended as the best 

 tree to plant in this sort of country, but in view of the imminent lia- 

 bility of the introduction of the pine rust (Periderniium sfrohi) it is 

 doubtful whether this species should be used. The observations re- 

 ported above (p. 295) indicate the advisability of giving the tulip-tree 

 (Lirioch )idron fulipifera) a trial even on the steep slopes. The prob- 

 ability is that it would not succeed in some of the most difficult situa- 

 tions which might be first seeded to some quick-growing cover. But 

 where it could be grown it would appear, on account of its rapid 

 growth, valuable timber, and freedom from insect and fungus enemies, 

 to be the most promising species with which to experiment.
