opment, of more widely-tried distribution, and adapted to soils 

 lacking in fertility ; thrives wherever our rainfall reaches an 

 average of sixteen inches, and resists extreme summer heat 

 well ; holds its lower branches and foliage with tenacity to a 

 great age, making it serviceable for wind-breaks or ornamental 

 hedging; the wood is light, but extremely durable under- 

 ground, making it valuable for posts. Its small size makes it 

 unavailable for general lumbering uses, other than as a cabinet 

 wood, for which it is well adapted. 



These two are the only native conifers that have been suc- 

 cessfully planted upon lands deficient in moisture and fertility, 

 upon a scale, and over a period of time prolonged enough, to 

 assert that they will prove valuable for our so-called arid 

 hill-sides. 



In a more experimental way, upon more restricted areas, 

 away from their native habitats, the subjoined coniferous spe- 

 cies have been planted, and success has only followed where 

 the soil was of reasonable depth, fair fertility, and where water 

 was not remote from the surface. Such plantations have 

 proven successful in the northern part of the State where water 

 surface was distant, but only where the average annual rain- 

 fall exceeds twenty inches, and where the plantations have 

 been made in nooks and valleys sheltered from drying winds. 



In the southern half of the State, these conditions are not 

 sufficient, and a deeply-cut, well-sheltered, canon canying 

 water upon or near the surface is a sine qua non. 



The species are : 



Sequoia sempervirens. 



Sequoia gigantea. 



Chamcecyparis Lawsoniana.
