“When the cableway is working we’ll start to build a miniature construction camp out there on the rock. There will be derricks, for one thing, for no man, or group of men, could handle one of those tremendous blocks without some mechanical assistance. It is probable that half a dozen derricks will be built during the course of construction work, for storms will sweep them away in a jiffy once the waves get piling up on the Head. We’ll be lucky if we don’t lose some of our workmen too. There’s many a lighthouse along the coast the building of which has cost more than one human life. This sort of work, my boys, is not the easiest in the—”

“Ow-w-w-w-ye-e-e-e-o! Ow-w-w-w-ye-e-e-o!”

“Good gracious, what’s that,” exclaimed Jack, jumping as if he had been shot.

Ray smiled and turned around slowly. “That’s a conch. Some one’s calling.”

“Yes, that’s Eli Whittaker’s dinner horn,” said Mr. Warner, smiling at Jack’s surprise.

“Call to dinner, is it?” said Jack, smiling too; “sounded to me as if a whole drove of elephants was charging down upon us. Well, if it means something to eat I’ll welcome it as terrible as it sounds,” said the lad from Vermont.

“So’ll I,” assured Ray, “though I don’t know how I’m going to handle a knife and fork with my arm out of commission.”

“Pooh, don’t mind that as long as your mouth isn’t in a sling,” said Jack. “I’ll cut up your food and you can use the fork with your good paw, can’t you?”

“Just watch me,” said Ray.

The sound of the conch was evidently the camp’s signal for dinner too, for as Jack and Ray and Mr. Warner walked back toward the lighthouse they passed scores of men on their way to the long, half-finished mess-hall where Bongo, the dusky cook, was piling a board table full of good wholesome victuals. The men of the crew were of all nationalities, but they were men every one of them. Jack noted the fact that every eye was clear and each moved with a stride that bespoke strength and agility. They were big chested and brawny and Jack did not know when or where he had ever seen finer specimens of manhood, a fact which he remarked to Ray and Mr. Warner.
