362 Select Plants for Industrial Culture and 



growing of European Firs in Tasmania [F. Abbott], A closely 

 cognate tree is the Algerian Fir, P. Numidica (Lannoy), which 

 occurs intermixed with the Atlas-Cedar at elevations from 4,000- 

 6,000 feet. 



Pinus polita, Antoine. 



Japan and Kurile-Islands. A tall superb spruce, forming large 

 forests 011 the mountain -ranges [A. Murray]. Resists severe frost. 

 Allied to P. Smithiana. Wood much like that of P. Alcockiana. 



Pinus ponderosa, Douglas.* (P. Benthamiana, Hartweg.) 



Yellow Pitch-Pine or Trucker-Pine. North -Western America. 

 Height of tree often to 225 occasionally to 300 feet, with a 

 stem reaching' 24 feet in circumference. Growth comparatively 

 quick. Thrives best in deep loamy sand, but grows also on dry 

 rocky ridges [Farlow]. Varies in degree of hardiness according 

 to the locality, in which the seeds were obtained [Prof. Th. Meehan]. 

 The wood is yellowish, hard, strong, heavy and durable ; for general 

 purposes it is locally preferred to that of other pines ; also largely 

 used in mining operations. There are tine groves of this tree up to 

 5,000 feet elevation in California, but the variety P. Engelmanni 

 (Parry) ascends to 12,000 feet. The bark contains a considerable 

 quantity of tanning substance. Wood pale and soft, neither knotty 

 nor resinous, much esteemed for cabinet-work [Hoopes] ; it is of 

 great strength, and used for floors, joists and much other work in 

 carpentry. Gibbons relates, that the wood, with the bark adherent, 

 exposed to the weather, will decay within a year, but that when 

 stripped and covered with soil it is readily persistent. Dr. Kellogg, 

 who aptly calls this tree herculean, saw logs, which had been in the 

 ground twelve years, quite sound. Sap-wood very thick. This 

 pine has proved well adapted even for rather dry localities in 

 Victoria, but is there slow of growth. P. latifolia (Sargent) is an 

 {allied species of Southern Arizona. 



Pinus Pseude-Strobus, Lindley. 



Mexico, up to 10,000 feet. This pine is superior in appearance 

 to any other Mexican pine ; height to about 80 feet. 



Pinus pung-ens, Michaux. 



South-E astern States of North -Am erica. Although seldom over 

 50 feet high, this pine has the recommendation of being of remark- 

 ably quick growth, especially in early life. This species is very 

 resinous, also powerfully and pleasantly odorous [Prof. Buckhout] ; 

 should prove of great value. Flower-spikes red; cones large and 

 early formed [Prof. Meehan].
