An observation is reported in the German 

 Resistance Dendrological Society of the resistance to 



of attack of the Nun (Lymantria monacha, 



Douglas Fir L.) by the Douglas Fir. Almost wholly 



to denuded shoots bud out in most cases and 



Insects. only few entirely denuded individuals have 



succumbed. Even two and three-year-old 

 plants did not suffer much from the ravages of the insect. In 

 view of the large quantity of foliage which the Douglas Fir pro- 

 duces, in order to destroy extensive Douglas Fir plantations, the 

 plague would have to develop in much greater numbers, than the 

 worst known. 



Sitka Spruce, Tsuga inert cnsiana and canadensis, Pinus strobus 

 and koraensis have been entirely free from attacks, accentuating 

 the value of the introduction of exotics.

Small forest owners can most profitably 

 Homegrown purchase such plants as their planting oper- 



or ations require and purchase is best made 



Nursery from some reliable firm making a business 



Stock? of growing forest trees for sale. The man- 



agement of a nursery is too exacting an un- 

 dertaking for one whose demands for plants are not large and 

 permanent enough to call for the employment of a skilled gar- 

 dener. In some cases the larger users of plant material produce 

 a surplus over and above their own needs and ofifer this for sale. 

 This class of material frequently consists of the poorest stock, the 

 owner keeping the better for his own use. There have been many 

 objections raised against the purchase of plants from nurserymen, 

 some of which are entirely unfounded and the rest valid against 

 none but a few untrustworthy producers of which it is strikingly 

 true that the evil they do lives after them. 



Plants produced by reliable nurserymen are grown under the 

 best possible conditions to develope into vigorous individuals, are 

 sorted, packed and shipped with elaborate precautions against 

 damage and reach the small planter in better condition and 

 cheaper than he himself can grow them.
