On the table, amid that bewildering assortment of queer-looking instruments, all scrupulously clean and highly polished, were two small brass lamps burning behind a long, narrow strip of transparent celluloid whereon was marked a minute gauge. On the edge of the table, before these lamps, was a switch, with black ebonite handle.

As the two Englishmen entered, the German’s eyes caught the small, round brass clock and noted that it was time to make the test—every five minutes, night and day, while the cable was in process of completion.

Therefore, without further word to his visitors, he carefully pulled over the long ebonite handle of the switch, and, at the same instant, a tiny spot of bright light showed upon the transparent gauge.

This the engineer examined to see its exact place upon the clearly-defined line, afterwards noting it in his book in cryptic figures, and then carefully switching off again, when the tell-tale light disappeared.

“Well?” asked Barclay. “How are you getting along? Not quite so much excitement in this place as yesterday—eh?”

“No,” laughed the engineer. “Der people here never see a shore-end floated to land wiz bojes (buoys) before. Dey have already buried der line in der trench, as you see. Ach! Your English workmen are far smarter than ours, I confess,” he added, with a pleasant accent.

“Is it being laid all right?” the airman asked.

“Ja, ja. Very good work. Der weather, he could not be better. We have laid just over one hundert mile in twenty-four hours. Gut—eh?”
