The heat did not affect _them_.
"My word!" said Sir Henry.
"It is hot!" echoed Good.
It was hot, indeed, and there was not a bit of shelter to be found.
Look where we would there was no rock or tree, nothing but an unending glare, rendered dazzling by the heated air that danced over the surface of the desert as it dances over a red-hot stove.
"What is to be done ?" asked Sir Henry; "we can't stand this for long." We looked at each other blankly.
"I have it," said Good, "we must dig a hole, get in it, and cover ourselves with the karoo bushes." It did not seem a very promising suggestion, but at least it was better than nothing, so we set to work, and, with the trowel we had brought with us and the help of our hands, in about an hour we succeeded in delving out a patch of ground some ten feet long by twelve wide to the depth of two feet.

Then we cut a quantity of low scrub with our hunting-knives, and creeping into the hole, pulled it over us all, with the exception of Ventvoegel, on whom, being a Hottentot, the heat had no particular effect.

This gave us some slight shelter from the burning rays of the sun, but the atmosphere in that amateur grave can be better imagined than described.

The Black Hole of Calcutta must have been a fool to it; indeed, to this moment I do not know how we lived through the day.

There we lay panting, and every now and again moistening our lips from our scanty supply of water.
