USES OF EUCALYPTS. . ol 
Mexico might be similarly divided into four Eucalypt areas. The 
territory of these divisions would not necessarily be contiguous, but 
would be determined by elevation rather than by latitude or longitude. 
USES OF EUCALYPTS. 
The Eucalypts probably serve more useful purposes than the trees 
of any other genus grown on the globe, except, possibly, the various 
palms. Their uses are very diverse. As they grow they serve as a 
forest cover to mountains, hills,-plains, and swamps, as wind-breaks, 
and as shade trees. While growing they are also the source of many 
gums and resins, and of honey. When cut, they furnish valuable tim- 
ber, excellent fuel, and avery useful oil. Besides all this, many of 
them are ornamental, and they have the reputation of improving the 
climate of the region in which they grow. Being hardwood trees, they 
serve the useful purposes that hardwood trees ordinarily serve, and 
besides furnish many useful products similar to those obtained from. 
a variety of other trees, and from shrubs and herbs. This great 
variety of uses is made available, in regions where they have but 
recently been introduced, by reason of their very rapid growth, it being 
possible to enjoy many of their uses while the trees are still standing, 
and to obtain from them many useful products within a very few 
years after planting them. 
AS A FOREST COVER. 
It is as forest trees that the Eucalypts are most useful; planted as 
ornamental or as shade trees they are often disappointing. Planters 
who have put them out as forest trees are the ones who have derived 
the greatest benefit from them. (Pl. I, 4.) Hon. Ellwood Cooper, 
of Santa Barbara, was one of the first Americans to recognize the 
prospective value of Kucalypts as forest trees. He acted upon his 
conviction, and has for a score of years been reaping the reward. 
Besides enjoying the beauty and shade of his groves, as well as the 
beneficial changes they have wrought in the climate of the region, he 
has for many years received from them an annual income of no incon- 
siderable amount. Those who have planted them singly or in small 
groups as ornamental or shade trees have received little or no financial 
return, and have in some cases been disappointed in them because not 
serving, as they had hoped, the purpose for which they were set. 
In many of the semitropic portions of the globe the Eucalypts are 
the trees most suitable to plant for forest cover. Much of the treeless 
land of semitropic America might be covered with these trees. As 
the conditions under which the different Eucalvpts grow in Australia 
are very diverse, it is evident that, if the species are properly selected, 
they will cover nearly all kinds of situations.
