Scarcely a week passes without thunderstorms and rain; but the latter falls in such small quantities that it is almost useless.

It is evidently on this account that there are no waters or watercourses deserving of the name.

I should like to know how much rain would have to fall here before any could be discovered lying on the ground.

All waters found in this part of the country must be got out of pure sand, in a water channel or pure rock.

The native orange-tree grows here, but the specimens I have met are very poor and stunted.
