Some of Mr Anderson's remarks on the natural appearances of Teneriffe,
and its productions, and what he observed himself, or learnt by
information, about the general state of the island, will be of use,
particularly in marking what changes may have happened there since Mr
Glas visited it. They here follow in his own words:

"While we were standing in for the land, the weather being perfectly
clear, we had an opportunity of seeing the celebrated Pic of Teneriffe.
But, I own, I was much disappointed in my expectation with respect to
its appearance. It is, certainly, far from equalling the noble figure of
Pico, one of the western isles which I have seen; though its
perpendicular height may be greater. This circumstance, perhaps, arises
from its being surrounded by other very high hills; whereas Pico stands
without a rival."

"Behind the city of Santa Cruz, the country rises gradually, and is of a
moderate height. Beyond this, to the south-westward, it becomes higher,
and continues to rise toward the Pic, which, from the road, appears but
little higher than the surrounding hills. From thence it seems to
decrease, though not suddenly, as far as the eye can reach. From a
supposition that we should not stay above one day, I was obliged to
contract my excursions into the country; otherwise, I had proposed to
visit the top of this famous mountain."[71]

Teneriffe, in Sprat's History of the Royal Society, p.200, &c. Glas also
went to the top of it.--History of the Canary Islands, p. 252 to 259. In
the Philosophical Transactions, vol. xlvii. p. 353-356, we have
observations made, in going up the Pic of Teneriffe, by Dr T. Heberden.
The doctor makes its height, above the level of the sea, to be 2566
fathoms, or 15,396 English feet; and says, that this was confirmed by
two subsequent observations by himself, and another made by Mr Crosse,
the consul. And yet I find that the Chevalier de Borda, who measured the
height of this mountain in August 1776, makes it to be only 1931 French
toises, or 12,340 English feet. See Dr Forster's Observations during a
Voyage round the World, p. 32.--D.]

"To the eastward of Santa Cruz, the island appears perfectly barren.
Ridges of hills run toward the sea; between which ridges are deep
valleys, terminating at mountains or hills that ran across, and are
higher than the former. Those that r
