EUCALYPTUS TREES. 5338 
Rubus rugosus, Smith. —South Asia. The fruit, 
which ripens here all the year round, is nearly twice 
the size of the ordinary blackberry. 
Salix alba, Linné. — With other large willows and 
poplars one of the best scavengers for back yards, where 
drainage cannot readily be applied ; highly valuable 
also for forming lines along narrow water-courses or 
valleys in forests, to stay bush- fires. The charcoal 
excellent for gunpowder. The wood in demand -for 
matches. s 
Secale creticum, Linné. — Though probably only a 
variety of S. cereale, L., it deserves specially to be 
mentioned as furnishing a bread of peculiar taste. 
Sequoia sempervirens, Endl. — Furnishes the red 
deal of California. Measurements up to 360 feet are 
on record. Its growth is about 32 feet in 16 years, 
Often found on metamorphic sandstone. 
Sequoia Wellingtonia, Seemann. — Traditional ac- 
counts seem to have overrated the height of the mam- 
moth tree. Inthe Calaveras grove two of the largest 
trees, which may have been the tallest of all, were 
destroyed ; the two highest now existing there are 
respectively 325 and 319 feet high, with a circumfer- 
ence of 45 and 40 feet at 6 feet from the ground. At 
the Mariposa grove the highest really measured trees 
are 272, 270, and 260 feet high, but one of these has 
the enormous circumference of 67 feet at 6 feet from 
the ground ; while another, the height of which is 
not recorded, is 93 feet in girth at the ground, and 64 
feet at 11 feet from it. The branches of this individ- 
ual tree are as thick as the stems of large elms. The 
height of the Calaveras grove is 4,760 feet above sea- 
level,
