UTILIZATION OF CALIFORNIA EUCALYPTS. At 
used extensively in California and have been shipped to Canada 
and the Eastern States. After fifteen years’ service, sound pins are 
still in use. 
Eucalyptus is sometimes used by farmers in California for wagon 
poles, shafts, axles, doubletrees, bolsters, spokes, hubs, felloes, and 
for the wooden parts of plows, harrows, and other agricultural 
implements, and, so far as known, it has 
given satisfaction. The results of the lab- 
oratory tests show that its strength is 
sufficient for vehicle construction. 
As yet the value of eucalyptus for coop- 
erage stock is unknown. A barrel com- 
pany in California made some 5-gallon and 
10-gallon kegs from blue gum, which pre- 
sented a satisfactory appearance. These 
kegs have been filled with wine to determine 
the effect of the wood upon it. 
Ax and pick handles have been made 
from blue-gum planks cut from young trees. 
The planks had been air seasoned for about 
two years, but the handles, particularly 
those for axes, warped excessively. 
Eucalyptus wood from immature trees 
may be regarded as having many pros- 
pective uses. The methods by which the 
wood is to be handled for the various uses 
are, however, not yet worked out, and 
many difficulties will doubtless be en- 
countered on account of the tendency of the 
wood to shrink, warp, and check. Until 
these tendencies can be controlled the 
waste in utilization must necessarily be 
very great, and returns from commercial 
plantations consequently will be lower than 
they otherwise would be.

Another possible source of revenue is the fee 
distillation of the leaves and twigs for the production of eucalyptus 
oil. The higher grades of eucalyptus oil are at present manufactured 
largely in Australia, and there seems to be no good reason why the 
same methods applied in this country should not produce equally 
valuable oil.
