Newcombe had constant difficulties owing to excess of zeal, and his habit of doing four times more than any other Englishman would do: ten times what the Arabs thought needful or wise. Hornby spoke little Arabic; and Newcombe not enough to persuade, though enough to give orders; but orders were not in place inland. The persistent pair would cling for weeks to the railway edge, almost without helpers, often without food, till they had exhausted either explosives or camels and had to return for more. The barrenness of the hills made their trips hungry for camels, and they wore out Feisal’s best animals in turn. In this Newcombe was chief sinner, for his journeys were done at the trot; also, as a surveyor, he could not resist a look from each high hill over the country he crossed, to the exasperation of his escort who must either leave him to his own courses (a lasting disgrace to abandon a companion of the road), or founder their own precious and irreplaceable camels in keeping pace with him. “Newcombe is like fire,” they used to complain; “he burns friend and enemy”; and they admired his amazing energy with nervous shrinking lest they should be his next friendly victims.
