evolved to resist prolonged periods of drought characteristic of so 
much of Australia. 
E. marginata has leaves somewhat paler beneath. Under the name 
of jarrah its timber has become renowned as a desirable, strong wood, 
capable of resisting the teredo, and consequently particularly adapted 
to piling. It is a tree well worth trying in southern Florida. It lives, 
but does not succeed for commercial promise, in the elimate of Calli- 
fornia. 
Another valuable timber tree of this unequally green leaf is EH. gom- 
phocephala, tooart gum. This tree grows well in California and makes 
a thick, symmetrical head, but is not a phenomenal grower. None of 
this type resist temperatures much below freezing; nor, with the excep- 
tion of the FH. corynocalyx, do they withstand dry air with long con- 
tinued high temperatures such as those occurring in central Australia, 
southern Algiers, Arizona, etc. 
SPECIES IN SOUTHERN FLORIDA. 
Mr. Alex. Bauer, of Wauchula, Fla., reports to the Division of For- 
estry, under date of April 18, that the past severe winter had killed 
or badly injured all his eucalypts. Among the growths reported by 
Mr. Bauer are the following: 
Eucalyptus (species unknown), planted Oetober 7, 1890, height 524 
feet, circumference at base 3 feet 10 inches. 
EH. raniculata, planted same date, height 42 feet, circumference at 
base 29 inches. 
EH. lanceolata, planted same date, trunk branched at surface, height 
27 feet, circumference at base 27 inches. = 
Mr. Bauer is not discouraged by the damage of last winter, but has 
already sent to Australia for a supply of seed for renewed experiments. 
I should think that. in middle and southern Florida the very hand- 
some E..calophylla would do well.. It has cream-white flowers, dark- 
green, shining foliage, and its timber is valuable. The fruit of this 
timber is large. A company here is polishing these fruits and making 
them into pipe bowls. 
A large and important group of the eucalypts has leaves dark shin- 
ing green above and pale beneath. This group has less or none of the 
sickle-shaped foliage, makes a better head and gives more shade, as the 
leaves are not generally, if at all, turned edgewise to the sun. The 
species in this group generally contain a large amount of kino. 
This kino is a gum something similar to the resin of our pines and 
more or less permeates the timber of these trees. It is usually red or 
reddish brown in color, has 4 powerful preservative effect on the tim- 
ber, antagonizing insect life, and has an antiseptic action. This latter 
property is availed of in medicine for the treatment of indolent ulcers, 
gangrenous tendencies, and is a deodorizer in external cancer. The 
foliage of this group is poor in the oil to which the therapeutic and 
hygienic reputation of the eucalypts is due.
