"Yes, I dare say, but I'm not particularly anxious to get a fellow to fill your place just as you're becoming useful. Your hydroplane is all very well as a plaything for your spare time; but it's no earthly use, and I only hope it won't lead you into scrapes. A stitch in time saves nine."

Will's eyes twinkled, and the ghost of a smile played about his lips. The Chief had a habit of finishing his little speeches with a proverb, not always appropriate to the occasion.

"Well now, this job," continued Mr. Jackson. "I want you to check some calculations of level about six miles up. Here you are, on the plan: that's the section. You've been over the ground before; it's the most difficult part of the track. You can take Ruggles as rodman. You'll be some time over the job, so take some grub with you, and be as quick as you can. Time and tide waits for no man."

"Can I have the plan?"

"No. Trace a copy of the section: it won't take you twenty minutes. And, I say, make sure your level's in order; it won't do to get there and find there's a screw loose. Look before you leap, you know."

Having traced the plan of the section he was to survey, Will got his instruments (a hand-level, a surveyor's camera, and a pocket compass), his revolver, and a note-book, sent José to find Ruggles and saddle a couple of ponies, and in half-an-hour set off on his task. The country, as the Chief had said, was the worst bit of the whole line. It was much broken by hills and ravines, and the surveyor, choosing the easiest way for the iron road, had been compelled to trace out a rather tortuous course, which was indicated by stakes driven into the ground at intervals. The line would twice cross the little stream which Will had recently navigated in his hydroplane. Fortunately it was fordable at both points.

Will rode on with his companion at a steady trot. Ruggles was a sturdy grizzled veteran of about fifty years of age. He was the handy man of the staff. He could act as rodman, chainman or slopeman as circumstances required. He could build a boat, repair an engine, and cook a dinner with equal facility, and once he surprised Will by helping him out in a knotty calculation in trigonometry. It had been a source of wonder to Will that a man whose attainments were so various should have risen no higher than the humble situation he at present occupied. One day he ventured delicately to hint at the matter.

"I'll never earn more than two pound a week as long as I live," said Ruggles.

"But why? I earn more than that, and you could do my work better than I can."

"Drink--that's why. Every sixpence I earned above two pound would go in drink, and so, to be on the safe side, I'm never going to earn a penny more, that's flat."
