And indeed I watched him with much interest. First he surveyed the country with great care through a field-glass. Then he squinted along a theodolite at a distant pole. Next he used a strange instrument which was, Jones told me, a wind-gauge, and tapped thoughtfully at a pocket-barometer. After that he produced paper and pencil, and was immersed apparently in difficult sums. Finally, he summoned one of his caddies, who carried a metal cylinder. A golf ball was connected to this by a piece of india-rubber tubing, and a slight hissing noise was heard.

"Putting in the hydrogen," explained Jones. "Everything depends upon getting the right amount. New idea? Not very; even a year ago you must have seen pneumatic golf balls—filled with compressed air? Well, this is only an obvious improvement. There, he's going to drive now."

And this he did, using a club unlike anything I had seen before. Then he surveyed the putting-green—about half a mile away—through his glasses, and remarked that it was a fairish shot, the ball being within three inches of the hole. His companion, who went through the same lengthy preliminaries, was less fortunate. In a tone of considerable disgust he announced that he had over-driven the hole by four hundred yards.

"Too much hydrogen," murmured Jones, "or else he got his formulæ muddled. Well, we can start now. Shall I lead the way?"

I begged him to do so. He in turn surveyed the country, consulted instruments, did elaborate sums, inflated his ball.

"Now," he said, at length settling into his stance, "now I'll show you."

And then he missed the ball clean.

... Of course he ought not to have used such language, and yet it was a sort of relief to find something about the game which was entirely unchanged.
