[Q] On the Culture and Uses of Potatoes, by sir John Sinclair, bart.
This is a subject becoming every year of greater moment, and attention
to it a national benefit. The reduction of bulk alone, facilitating
the transport from one place to another, is an essential gain. The
produce, from a certain number of acres of this valuable esculent, may
be greatly augmented by planting the potatoes whole, at a great
distance between each, and hoeing freely between them--_See Knight's
Papers in Horticultural Transactions, and Payen et Chevalier, Traite
de la Pomme de Terre. Paris, 1826, p. 17._

[S] "Among the plants cultivated by man, the sugar-cane, the plantain
(_musa_), the mammee-apple (_mammea_), and alligator-pear-tree
(_laurus persea_) alone have the property of the cocoa-nut-tree, that
of being watered alike with fresh and salt water. This circumstance is
favorable to their migrations; and if the sugar-cane of the shore
yield a syrup that is a little brackish, it is believed at the same
time to be better fitted for the distillation of spirit, than the
juice produced from the canes of the interior."--_Humboldt._

[T] "The quantity of these insects is incredible to all who have not
themselves witnessed their astonishing numbers; the whole earth is
covered with them for the space of several leagues. The noise they
make in browsing on the trees and herbage may be heard at a great
distance, and resembles that of an army in secret. The Tartars
themselves are a less destructive enemy than these little animals. One
would imagine that fire had followed their progress. Wherever their
myriads spread, the verdure of the country disappears; trees and
plants stripped of their leaves and reduced to their naked boughs and
stems cause the dreary image of winter to succeed in an instant to the
rich scenery of spring. When these clouds of locusts take their
flight, to surmount any obstacles, or to traverse more rapidly a
desert soil, the heavens may literally be said to be obscured by
them."
