the pole stage of growth by the Agaricus melleus, 

 a root parasite which often perforates the plants 

 to a most serious extent, and it is only by the 

 planting of a rapid growing species of broad- 

 leaved tree, such as alder, ash, and red oak with 

 it that such danger can be averted. The cotton 

 louse, Ckermes strobi, has a special tendency to 

 fall upon the Weymouth pine in its twentieth 

 year, lessening its height growth and destroying 

 weak plants. It is more particularly exposed to 

 the ravages of forest animals, nibbling of the 

 sprigs and gnawing the bark (especially by deer), 

 so that a certain German forester to whom deer- 

 stalking, &c., is everything, proposed in all 

 seriousness to do away with the Weymouth pine 

 on account of these ravages. As regards its 

 timber, the Weymouth pine is, in its early years, 

 much tougher than that of the common pines, 

 and succumbs much less frequently to snow- 

 pressure and breakage. Investigations on the 

 subject of the sylvicultural peculiarities of the 

 Weymouth pine, just alluded to, have been more 

 especially carried out, apart from the other 

 authors named, by Dr. Wappes, 1 Prof. Dr.
