120 THE CULTIVATED EVERGREENS 



sus arizonica, Abies Pinsapo and A. concolor, Picea pungens var. 

 Kosteriana. Other species worthy of mention are: Cryptomeria 

 japonica var. elegans, Thuja orientalis var. aurea, Cupressus 

 sempervirens and C. macrocarpa, Pinus radiata, and Juniperus 

 chinensis. 



In the cold snaps of January, in the years 1913 and 

 1922, many of the largest and oldest Araucaria excelsa were 

 frozen to death and size and age seemed to be no protection, 

 as it is generally conceded to be with trees in general. Some 

 of the very largest in Los Angeles perished, and they seemed to 

 be frozen in all parts, from the base of trunk covered with 

 thick bark, up to the tip, seventy-five or more feet above. 

 This freezing of mature bark-protected trunks is believed to be 

 due to continuation of low temperatures through several 

 nights, which was cumulative in effect, gradually breaking 

 down the tissues. Lower temperatures of shorter duration 

 would not have resulted in such fatalities, which, strange to 

 say, were not visited upon any other conifer. 



The remarkable ease with which the Monterey pine and the 

 Monterey cypress may be grown from seeds and safely trans- 

 planted, coupled with their drought-resistance, have made them 

 prime favorites for covering bare hillsides when landscape 

 effect is sought. When fuel is desired, eucalypts are planted. 

 California, except in very cool and damp coastal districts, is 

 too hot and dry during summer to suit some very ornate 

 species. Araucaria hrasiliana and Cunninghamia lanceolata are 

 two of this class. Unless planted in a lawn, where there is a 

 constantly rising humidity, Araucaria araucana grows but 

 slowly and is poorly furnished with branches near the ground. 

 In Golden Gate Park, San Francisco, it reaches a better 

 development than at any point farther south. Cedrus Deodar a 

 has proved a pleasant surprise in its really remarkable adapta-
