about two o'clock
We walked no longer , we staggered , now and again falling from exhaustion , and being obliged to call a halt every hour or so . We had scarcely energy left in us to speak . Up to this Good had chatted and joked , for he is a merry fellow ; but now he had not a joke in him . At last , about two o'clock , utterly worn out in body and mind , we came to the foot of the queer hill , or sand koppie , which at first sight resembled a gigantic ant-heap about a hundred feet high , and covering at the base nearly two acres of ground . Here we halted , and driven to it by our desperate thirst , sucked down our last drops of water . We had but half a pint a head , and each of us could have drunk a gallon . Then we lay down .
