In the Austrian forests this tree reaches a height of eighty to 120 feet 

 and a diameter of three feet. It grows rapidly and well adapts itself to a 

 variety of soils. On account of its dense foliage it is suitable for backgrounds 

 in landscape architecture. It has a long tap root which makes it wind firm 

 and this quality together with its compact foliage makes it desirable for wind- 

 breaks. It is also well adapted for planting in cities,.since it is highly resistant 



to smoke. 



MONTEREY PINE 



The Monterey pine (Pinus radiata) is a native of California where it 

 occurs in patches for a distance of 130 miles along the coast south of San 

 Francisco Bay. It reaches its best development near Monterey, where the 

 trees average forty to sixty feet high and one to two feet in diameter. Near 

 the sea the trees lose their upright character and are distorted by the wind 

 into many fantastic shapes. Monterey pine is not cut into lumber these 

 days because of the knottiness of the wood, but the early Spaniards used it 

 somewhat for boat building eighty years ago. 



From early days this tree has been extensively planted for ornamental 

 purposes and windbreaks, not only in California but in England and Aus- 

 tralia where it makes a remarkable growth. It has a very symmetrical, narrow 

 and round topped crown, and rich green leaves beautifully arranged in clumps 

 on the branches. The growing season is practically continuous. At Berkeley 

 trees attain a height of sixty to ninety feet in thirty years. 



The Monterey pine is a comparatively short-lived species and begins to 

 show signs of old age under cultivation at the end of thirty-five or forty years. 

 It will not thrive on wet soils, preferring the slopes, bluffs, ridges and the well 

 drained soils of the coast. It thrives best when the annual rainfall avpragps 

 about seventeen inches. 



For a rapid growth conifer, this species is unexcelled. It is useful for soil 

 protection in semiarid regions, and serves well as a windbreak tree, besides 

 being good for fuel. Its short life and susceptibility to insects and fungous 

 diseases, however, are disadvantages which often cause other species to be 



chosen. 



TORREY PINE 



Torrey pine (Pinus torreyana) occurs naturally only in a small area on 

 the California coast at Del Mar near San Diego and on Santa Rosa Island. It
