238 APPENDIX. 



All these are species reaching heroic dimensions, and the 

 first and last rank in the very first class as unsurpassed timber 

 trees. 



The limits of their utility for forest planting is, owing to the 

 conditions stated above, restricted to very narrow limits. 



Pinus Sabiniana and Juniperus California both extend into 

 the lower foot-hills, and naturally occur upon barren, stony 

 lands of poorest quality ; and though nothing more than occa- 

 sional experimental tests have been made, no question or 

 doubt as to their utility upon utterly waste lands exists. 



Their relatively slower growth, and inferior fuel and timber 

 value, to the Monterey pine and Monterey cypress, explain 

 their neglect, rather than any doubt as to their successful 

 development. 



For points where the conditions of soil and climate discour- 

 age the planting of the latter, these two species can be success- 

 fully introduced. 



Of our native oaks, occasional tests have been made with a 

 few species. The most valuable, the Quereus densiflora, makes 

 but poor growth outside of humid and elevated ravines. Quer- 

 cus lobata demands soil of both depth and fertility. Under 

 these conditions it makes phenomenal growth. I have cut a 

 tree displaying but forty-five annular rings, that measured four 

 feet ten inches in diameter above any buttress. 



Quercus agrifolia has proven most tractable of all upon dry, 

 stony sites. Transplants easily, and after establishment makes 

 fairly rapid growth. Its rather small size is an objection. The 

 timber is inferior, stands but little transverse strain, but yields 

 a superior fuel. 



With our other trees no transplantations other than orna-
