midnight
At nightfall they again started , their course leading steeply up the gorge in which they had rested . Although the pathway became more and more indistinct , Ghamba appeared never to be at a loss . Langley several times shuddered , when they passed by the very edge of some immense precipice , or clambered along some steep mountain-side , where a false step would have meant destruction . He began to show signs of fatigue soon after midnight , so at Ghamba 's suggestion a considerable portion of his load was transferred to the shoulders of Whitson , who seemed to be as tireless as Ghamba himself . At daybreak they halted in the depths of another tremendous gorge with precipitous sides . The scenery in this particular area of the Drakensberg range , the neighbourhood of the Mont aux Sources , is indescribably grand and impressive , and is quite unlike anything else in South Africa . Enormous and fantastically shaped mountains are here huddled together indiscriminately , and between them wind and double deep gloomy gorges , along the bottoms of which mighty boulders are thickly strewn .
