The plantain bears at 1,529 yards, in a temperature of 61 deg.
Fahrenheit, and requires fifteen months, but its cultivation is of
little benefit in so high a latitude. It is the same with the cassava
root. The cane at 1,160 altitude, in a temperature of 66 deg., gives
no sugar; and indigo at 1,620 affords no coloring matter.




SECTION I.

DRIED LEAVES, SEEDS, AND OTHER SUBSTANCES USED IN THE PREPARATION OF
POPULAR DIETETIC BEVERAGES.


No substances are so essentially necessary to mankind, or form such
important articles of commerce, as those which we come first to
consider, the dietetic products--cacao, coffee, tea, and sugar. The
consumption of these in all civilized countries is immense,
notwithstanding that in many they have been fettered with heavy fiscal
duties. The investigation of the culture of the plants from which they
are obtained, and the manufacture of the products, is a very curious
object of research.
