EUCALYPTUS TREES. 605 
Cranberry (Vaccinium macrocarpum) is annually much 
increasing in some of the States; boggy sands of the 
savannahs, cleared of Cedar brushes (Taxodium dis- 
tichum), being chosen for this culture. In New Jer- 
sey about 1,800 acres are now in bearing,* and about 
4,000: acres more were, up to 1869, planted with Cran- 
berries. The profit on the capital thus invested is 
from 25 to 50 per cent. annually. One grower real- 
ized, in eighteen years, from only ten acres Cranberry 
land, a fortune of £40,000. In the United States 
many thousand people are employed almost exclu- 
sively in picking this and kindred fruits. In June 
commences the harvest of Strawberries ; a month later 
follows the Raspberry ; then comes the Blackberries ; 
in August commences the gathering of Whortleber- 
ries ; after that the picking of Cranberries is proceeded 
with, which extends to November. + 
The miners, in prospecting through the ranges, 
might scatter the seeds of berries of those kinds along 
water-courses, or set out plants along rivulets or 
springy spots, from whence, when left to themselves, 
they would be sure to spread. The explorers of the 
_ interior, by strewing a few seeds of Acacia lophantha, 
_ Casauarina quadrivalvis, or some Eucalypts over their 
camping-ground, might yet more permanently indi- 
- eate these bivouacs than even by burning or cutting 
letters in many trees. In all this a botanic garden 
has a fruitful field for exertions. I endeavored to 
naturalize the medicinal squill on our sea- shores. 
Lately the American species of Sumach have come in 
* Producing 150000 bushels in 1869, worth 12s. per bushel, therefore 
- £90,000 the year’s crop in that small State.
