Zii SELECT PLANTS FOR INDUSTRIAL CULTURE 



Mediterranean. Height of tree 60 feet. The wood is whit- 

 ish, light, but full of resin, and much used for buildings, 

 furniture, and ships. The seeds are edible, somewhat resem- 

 bling almonds, but of a resinous though not disagreeable 

 taste ; they should be left in the cones until they are about to 

 be used, as otherwise they speedily become rancid ; they only 

 ripen in their third year. This Pine grows as easily and 

 almost as quickly as the Cluster Pine. 



Pinus Pinsapo, Boissier. 



Spanish Fir, In Spain, on the Sierra Nevada, 4,000 to 6,000 

 feet. A tree 60 feet high, with branches from the ground. 

 The timber is similar to that of the Silver Fir. 



Pinus polita, Antoine. 



Japan and Kurile Islands. A tall superb tree, forming large 

 forests on the mountain ranges (A. Murray) . 



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



Yellow or Pitch Pine or Trucker Pine of the mountains of 

 North-West America. Height of tree up to 225 feet, with a 

 stem of 24 feet in circumference, of comparatively quick 

 growth. The wood is heavy, and for general purposes pre- 

 ferred to that of any other Pine. There are fine groves of 

 this tree up to 5,000 feet in California. P. JefEreyi (Murray) 

 is, according to Dr. Vasey, a variety of this species. The 

 variety P. Englemanni, PaiTy, 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 is 

 used for floors, joists, etc. Dr. Gibbons relates that the wood, 

 with the bark adherent, exposed to the weather, wUl decay 

 within a year, but that when stripped and covered with soil 

 it is very durable. Dr. Kellogg saw logs which had been in 

 the ground twelve years quite sound. Has proved well adapted 

 even for dry localities, in Victoria. 



Pinus pseudo-strobus, Lindley. 



In Mexico. This tree is superior in appearance to any other 

 Mexican Pine; height 80 feet. 



Pinus pungens, Michaux. 



Eastern States of North America. Although seldom over 50 

 feet high, this Pine has the recommendation of being of remark- 

 ably quick growth.
