being crooked, and not equal in beauty."

[Footnote 74: The writer of the Relation of Teneriffe, in Sprat's
History, p. 207, takes notice of this lemon as produced here, and calls
it _Pregnada_. Probably, _emprennada_, the Spanish word for impregnated,
is the name it goes by.--D.]

"From him I learnt also, that a certain sort of grape growing here, is
reckoned an excellent remedy in phthisical complaints; and the air and
climate, in general, are remarkably healthful, and particularly adapted
to give relief in such diseases. This he endeavoured to account for, by
its being always in one's power to procure a different temperature of
the air, by residing at different heights in the island; and he
expressed his surprise that the English physicians should never have
thought of sending their consumptive patients to Teneriffe, instead of
Nice or Lisbon. How much the temperature of the air varies here, I
myself could sensibly perceive, only in riding from Santa Cruz up to
Laguna; and you may ascend till the cold becomes intolerable. I was
assured that no person can live comfortably within a mile of the
perpendicular height of the Pic, after the month of August."[75]

[Footnote 75: This agrees with Dr T. Heberden's account, who says that
the sugar-loaf part of the mountain, or _la pericosa_, (as it is
called,) which is an eighth part of a league (or 1980 feet) to the top,
is covered with snow the greatest part of the year. See Philosophical
Transactions, as quoted above.--D.]

"Although some smoke constantly issues from near the top of the Pic,
they have had no earthquake or eruption of a volcano since 1704, when
the port of Garrachica, where much of their trade was formerly carried
on, was destroyed."[76]

[Footnote 76: This port was then filled up by the rivers of burning lava
that flowed into it from a volcano; insomuch that houses are now built
where ships formerly lay at anchor. See Glas's History, p. 244.--D.]

"Their trade, indeed, must be considered as very considerable; for they
reckon that forty thousand pipes of wine are annually made, the
greatest part of which is either consumed in the island, or made into
brandy, and sent to the Spanish West Indies.[77] About six thousand
pipes were exported every year to North America, while the trade with it
was uninterrupted; at present, they think not above half the quantity.
