140 SILVA OF NORTH AMERICA. CONIFER. 
The trunks of Sequoia are largely manufactured into lumber used in construction and the interior 
finish of houses, and for fencing and railway-ties. 
Comparatively few insects’ prey upon Sequoia, which is free from serious fungal diseases.” 
Sequoia can be easily raised from seeds, which germinate usually at the end of a few weeks. 
The name of the genus immortalizes Sequoyah,* the inventor of the Cherokee alphabet. 
1 Little is known of the insects which attack Sequoia. The most 
destructive is Bembecia Sequoie, Henry Edwards, which, it is said, 
“is devastating the Pine forests of Mendocino County, California, 
and is particularly destructive to Sequoia sempervirens, Pinus pon- 
derosa and Pinus Lambertiana. The eggs appear to be laid in the 
axils of the branches, the young caterpillar boring in a tortuous 
manner about its retreat, thus diverting the flow of sap, and caus- 
ing large resinous nodules to form at the place of its workings. 
These gradually harden, the branch beyond them dies, and the tree

trees in the forests of the region indicated are to be seen in various

serious diseases. 
Sequoia sempervirens and about ten on Sequoia Wellingtonia. Among 
the latter may be mentioned Scleroderris Sequoic, Saccardo, which 
occurs on the trunks, and Lachnea Sequoia, Saccardo, and Lestadia 
consociata, Cooke, on the leaves. Sequoia sempervirens is attacked 
by such widely spread species as Hypocrea rufa, Fries, Pitya Cu- 
pressi, Saceardo, Stictis versicolor, Fries, and by special parasites 
like Amphispheria Wellingtonie, Berlese & Voglino, Leptostroma 
Sequoie, Cooke & Harkness, Melanopsamma confertissima, Saccardo, 
and other small species not found upon other hosts. Young plants 
of Sequoia Wellingtonia cultivated in Europe are said to suffer from 
attacks of a species of Botrytis, and a species of the same genus 
has been reported on wild trees in this country, although it is not 
known whether or not the same species attacks these trees in Cali- 
fornia and Europe. 
° George Guess or Sequoyah (about 1770-August, 1843), a 
Cherokee half-breed, was first known as a small farmer in the 
Cherokee country of Georgia, and as a skillful silversmith. In 
1826 he published his syllabic Cherokee alphabet of eighty-five 
characters, each representing a single sound, which was afterward 
used in printing The Cherokee Phenix, a journal devcted to the 
interests of the Cherokee nation, and a portion of the New Testa- 
ment. Guess moved with his tribe to the Indian Territory, and 
died in San Fernando in northern Mexico.
