236 APPENDIX. 



No attempt or experiment with exotic species has ever been 

 tried within the timber belt, and the values of the endemic 

 species, and their readiness to conform to such unpromising 

 situations as those described, justify us in thinking that they 

 will best fulfil future systematic mountain reforestation. 



PART II. 



SPECIES USEFUL FOR REFORESTATION OF FOOT-HILL-LANDS, 

 WASHES, OR LANDS UNSUITABLE FOR GENERAL AGRI- 

 CULTURE IN CALIFORNIA. 



(A) Endemic Species. 



First among them I rate the Pinus insignis, or Monterey 

 Pine. Naturally restricted to a narrow strip of land upon the 

 Mid-California seaboard, not extending inland more than ten 

 miles, it has taken kindly to transplantation to the interior 

 hotter, drier valleys for more than one hundred miles from 

 the sea. It rarely exceeds a height of thirty metres ; the tim- 

 ber is generally twisted, coarse in grain, deficient in strength, 

 not durable, and rates low for either lumber or fuel uses. Its 

 pre-eminent value is as a forest cover and wide adaptability to 

 soil and climate. 



Extensive plantations upon arid, gravelly hill-sides, without 

 care or cultivation, have attained an average height of twelve 

 feet in five years from the seed, and isolated specimens have 

 made a growth of sixteen feet during that time. It resists 

 fire well, young plantations where badly burned over i.e., with 

 three-quarters of the foliage destroyed generally recuperating. 



Cupressus macrocarpa, a smaller tree, fifty to seventy feet, 

 nearly as local as the Pinus insignis, of still more rapid devel-
