Here the approximation of the Apennines to the sea, at once keeps off
the north and east winds, and reflecting the sun's rays, affords the
temperature which the orange, lemon, &c. require. The moment you recede
from the coast, especially if a very trifling elevation of ground takes
place, farewell to oranges and lemons at least in any perfection.
_Sweet Lemon._--At Naples a curious variety of lemon is exposed in the
streets for sale, having externally the exact colour and shape of an
orange, except that at the stalk end is a depression, and on this a
prominence, as in the lemon, but within having the pale pulp of the
lemon, and sweet juice.
_Economy._--In the square of the town of Caserta, Mr. Spence saw exposed
for sale bundles of green lupine plants pulled up by the roots, and of
the roots of couch grass, which we burn, but which the Italians more
wisely give as a saccharine and grateful food to horses.
_Campagna Felice_ is the title given to the extensive tract of land
which lies between the mountains to the north-east of Caserta and
Naples, and the Mediterranean.
