Tur Repwoop (Sequoia sempervirens, Endl.) If free growth 
and rapid development were the only qualifications necessary to 
make this tree a success in British forests, it might be planted 
without further delay, but it remains to be proved whether the 
timber will be good enough to warrant extensive plantations. The 
important place occupied by the species in the lumber trade of 
America, is, however, a sufficient recommendation to warrant it a 
good trial here. . 
~ An idea of its rapid growth in the British Isles may be gathered 
from the fact that, although it was not introduced before 1846, 
there are numerous trees between 70 and 110 feet in height, with 
girths ranging from 8 to 14 feet. As fast growth is quite natural 
_to the ‘tree, there is no reason to suppose that the timber from 
forest-grown examples would, on that account, be so coarse as that 
produced by ornamental specimens. Seas 
Sequoia sempervirens is a native of California and is found from 
the northern boundary of the State, southward to the southern 
boundary of Monterey County, on the mountain slopes and on flat 
lands near the rivers, where the atmosphere is moist and the 
temperature fairly equable. ‘ 
- The United States Department of Agriculture, Forestry Section, 
has published a Bulletin, No. 38, on “ The Redwood.” It is divided 
into three parts, i, “ A Study of the Redwood” ; ii, “The Brown 
Rot Disease of the Redwood ”; iii, “ Insect Enemies of the Red- 
wood.” In this Bulletin, which is well illustrated, the redwood and 
its peculiarities are dealt with very fully, and the following notes 
have been extracted. The tree reaches its greatest size on the 
flats where the soil is moist and the atmosphere misty. Under 
such conditions it grows to a height of 350 feet with a diameter of
