It from North America, for internal consumption, as well as for 
the use of the navy. The large-fruited American vaccinium 
has been successfully cultivated at Spring-Grove, the country 
house of the late Sir Joseph Banks, near London, for several 
years. This shrub produced flowers and fruit the first year, 
and the quantity obtained the following harvest was still more 
abundant. It gradually threw out spreading roots like those 
of the gooseberry, but longer, and which took with more diffi- 
culty; they succeeded, however, and afforded at the proper 
time in spring, branches from ten to twelve inches long, with 
flowers. The berries were gathered, and were found excellent, 
and much superior to those commonly imported. The ground 
employed for this purpose was 326 square feet, while the quan- 
tity used for the cultivation of gooseberries in Spring-Grove gar- 
den, is 5,646 square feet, deduction made of the spaces left be- 
tween each row. It is to be remarked, that the harvest of these 
berries has been constantly abundant for seven successive years, 
without having been damaged by the vicissitudes of the weather, 
by mildew, or by any other accident. The flowers, which have 
expanded abundantly in the season, have been blasted in much 
smaller number than in the other species of plants. The fruit 
has been developed, and has acquired its full maturity, without 
being attacked by Insects, and without suffering from excess of 
cold or heat, rain or dryness *.

25. Steam Navigation .- While a great steam- vessel is crossing 
the Atlantic Ocean from the mouth of the Thames to the mouth 
of the Ganges ; while other English vessels of the same descrip- 
tion are intended to establish communications between Alexan- 
dria and the Island of Malta, several undertakings of a like na- 
ture, although not so extensive, are daily tending to give a greater 
activity to the navigation between the trading ports, upon the 
lakes and in the internal seas of Europe. A steam-boat goes 
from Hamburg to London in sixty hours : Another navigates 
between Kiel and Copenhagen, across the Baltic : A company 
is forming at Copenhagen, at this moment, for establishing a 
* The fruit of the Vaccinium oxycoccos (Cranberry) is, in the opinion of many, 
superior as an article of domestic use to that of the V. macrocarjnm , and Mr 
Mylne of the Fulham Nurseries, has found that it is easily susceptible of garden 
cultivation.
