4- DEVELOPED BY SEMI-TROPIC HEAT. 



The fourth factor necessary, it is found, for the 

 production of largest growths, is a high degree of 

 heat, of which the Puget Sound region lacks suffi- 

 cient for some plants, although many of her trees, 

 such as the Noble, Grand, and Amabilis firs, and 

 the very valuable Gigantic Cedar, or Shingle tree, 

 became monsters, and the Douglas Spruce, one of 

 the most valuable timber trees on the earth, be- 

 comes in Oregon and Washington the tallest trees 

 known, 450 to probably 480 feet high! 



This necessary heat is found under the semi- 

 tropic sun in the latitude of California. This heat 

 added to the enclosed condition of the state the 

 high Sierra on one side, the lower Coast Range on 

 the other admitting the ocean breezes through its 

 passes, and with low interlocking ranges at each 

 end furnishes just the right conditions, it seems, 

 for strongest allurement to enter and for highest 

 development afterward, for here only, in this cul- 

 de-sac of California, are found the largest cone- 

 bearing trees on earth, of some nine different 

 genera; and here only are found the largest and 

 heaviest cones of sixteen different species! 



Is it not passing strange that out of the twenty 

 pines of Europe and Asia, and the twelve pines of 

 the eastern states, not one should develop cones as 

 large as either one of five pines in California? 



TRIBUTE TO CALIFORNIA CLIMATE. 



The great truth is forced upon the attention that 

 it is California that was set apart from all the 

 world, when, as the geologists tell us, the Pacific
