"In that case we'll boot and saddle an hour before sunrise," declared Wilmshurst. "My man, Bela Moshi, will be able to follow the spoor like a cat.... Oh, yes, light as many fires as you like. Von Gobendorff is too far away to see the glare."

The night passed quietly. Although there were wild animals prowling round they kept a respectful distance. Men in pairs took turn in keeping watch, their comrades lying wrapped in blankets, with their feet towards the fire, each with his loaded rifle by his side.

After a good meal, consisting of roast goat's-flesh, millet bread and hot chocolate, the trek was resumed, the Haussa following the spoor with the sagacity and skill of a sleuth-hound until it was light enough to enable the Rhodesians to follow up the trail.

After a distance of five miles had been covered the patrol halted in perplexity, for, seemingly from nowhere another spoor joined that of the one they were following. There were distinct imprints of two men walking—one wearing veldt-schoen, the other the heavy marching boot supplied to the German colonial units.

The latter was of slightly recent origin, as witnessed by the fact that here and there the footprints of the boots had partly obliterated those of the veldt-schoen.

"It strikes me we've only just tumbled on the right spoor," declared a Rhodesian. "Of the two I should imagine von Gobendorff was wearing military boots. I suppose you didn't happen to notice what he wore while he was attached to the Waffs?"

"Boots and gaiters," replied Wilmshurst. "But, of course, that was some time ago."

"And boots are scarce in this show," rejoined the other tentatively. "When a man gets used to wearing a certain pair he's not likely to discard them in a hurry. I'll bet that is von Gobendorff's trail."

"And the other?" asked Dudley.

"A nigger might be wearing veldt-schoen," suggested another Rhodesian. "Perhaps he looted them, and in his natural vanity, decided to put them on instead of slinging them round his neck. In my experience I find that a native 'boy' will wear veldt-schoen, but he'll draw the line at boots."
