 tressed at base, covered with thick, fibrous bark, deeply 

 and widely lobed; heartwood dark red, soft, durable,

 and parts of Europe, but now liiiiitc.l tc. two species, 

 which are conlined to the mountains of California. 



The wood of S. sempervireiis at present forms the 

 bulk of the redwood lumber in the trade, and is used 

 on the Pacific coast wherever a light, durable, easily 

 worked material is desired. Most wooden buildings are 

 constructed with this lumber in California, and it is 

 sometimes exported to Europe to be employed as a sub- 

 stitute for red cedar in the manufacture of lead-pencils. 

 Logs with a curly grain are highly prized by cabinet- 

 makers, from whom they have received the name "curly 

 redwood." 



The wood of S. gigantea resembles that of S. semper- 

 virens, but is coarser-grained and lighter (In weight), 

 and is therefore not adapted to :is wiilc U'-i' as the latter. 

 It is very durable in contact with tin- s..il, li.nvever, and

S. gigantea has been more widely pla 

 and in JEurope, and in sheltered locations has maintained 

 itself for a number of years. The most notable exam- 

 ples are those in the Ellwanger & Barry grounds, at 

 Rochester, N. Y., which are now about 40 yrs. old, 30 

 ft. high and 12 in. in diameter at base of trunks. When 

 seen in the winter of 1900-1, however, these trees were 

 beginning to show the effects of the rigorous climate by 

 their dead and dying tops. This species is far more

hardy than S. scmpervirens , and even in the dry climate 

 of southern California is reported to be doing very well. 

 A weeping variety known as S. pendula is advertised, 

 which originated some years ago in European nurseries, 

 and is described as having "all pendulous branches, 

 closely pressed against the stem." Both species are said 



to dislike heavy soils, and to thrive best when planted in 

 deep sandy loam. Both are easily propagated from seed, 

 which sprout readily in a few weeks.

 distichum, the deciduous cypress. Lilir nearly all lax- 

 ads, the deciduous cypress has a very ancient relation- 

 ship among fossil trees; it once grew on a large part of 

 western Europe and portions of England. Forms of 

 Sequoia, whose ancient history constitutes one of the 

 most interesting chapters in fossil botany, once grew in 

 immense forests in Europe, Asia and North America. 

 The first fossil remains occur in the lower chalk-forma- 

 tions and increase in extent to the tertiary strata, in 

 which they are numerous. In miocene times, fossil Se- 

 quoias extended "from the Hebrides to the Steppe of 

 Kirghis." Asa Gray and others have told the story of 

 the rise and fall of this great and strong family of coni- 

 fers, once as powerful as any tree-group in the world.
