During the greater part of our stay of a week the sky was
cloudless, and if the trade-wind failed for an hour the heat became
very oppressive. On two days the thermometer within the tent stood
for some hours at 93 degrees; but in the open air, in the wind and
sun, at only 85 degrees. The sand was extremely hot; the
thermometer placed in some of a brown colour immediately rose to
137 degrees, and how much above that it would have risen I do not
know for it was not graduated any higher. The black sand felt much
hotter, so that even in thick boots it was quite disagreeable to
walk over it.
