“It may seem so here,” said Margaret Raleigh, “but it will be quite another thing out under the arctic ice.”

Preparations for the expedition were pushed forward as rapidly as possible, and Clewe would have been delighted to make this voyage into the unseen regions of the nether ice, but he knew that it was his duty not to lose time or to risk his life when he was on the brink of a discovery far more wonderful, far more important to the world, than the finding of the pole. Therefore he determined that he would go with the expedition no farther than the point where the ice would prevent the farther progress of the vessel in which they would sail from New York.

It was not to be supposed that Roland Clewe intended to intrust such an expedition to the absolute command of such a man as old Samuel Block. There would be on board the Dipsey an electrician who had long been preparing himself for this expedition; there were to be other scientific men; there would be a submarine engineer, and such minor officers and assistants as would be necessary; but Clewe wanted some one who would represent him, who could be trusted to act in his place in case of success or of failure, who could be thoroughly depended upon should a serious emergency arise. Such a man was Samuel Block, and, somewhat strange to say, old Sammy was perfectly willing to go to the pole. He was always ready for anything within bounds of his duty, and those bounds included everything which Mr. Clewe wished done.

Sammy was an old-fashioned man, and therefore, in talking over arrangements with Roland Clewe, he insisted upon having a sailor in the party.

“In old times,” said he, “when I was a young man, nobody ever thought of settin' out on any kind of sea-voyagin' without havin' a sailor along. The fact is, they used to be pretty much all sailors.”

“But in this expedition,” said Clewe, “a sailor would be out of place. One of your old-fashioned mariners would not know what to do under the water. Submarine voyaging is an entirely different profession from that of the old-time navigator.”

“I know all that,” said Sammy. “I know how everything is a machine nowadays; but I shall never forget what a glorious thing it was to sail on the sea with the wind blowin' and the water curlin' beneath your keel. I lived on the coast, and used to go out whenever I had a chance, but things is mightily changed nowadays. Just think of that yacht-race in England the other day—a race between two electric yachts, with a couple of vessels ploughin' along to windward carryin' between 'em a board fence thirty feet high to keep the wind off the yachts and give 'em both smooth water and equal chance. I can't get used to that sort of thing, and I tell you, sir, that if I am goin' on a voyage to the pole, I want to have a sailor along. If everything goes all right, we must come to the top of the water some time, and then we ought to have at least one man who understands surface navigation.”

“All right,” said Clewe; “get your sailor.”

“I've got my eye on him; he's a Cape Cod man, and he's not so very old either. When he was a boy people went about in ships with sails, and even after he grew up Cap'n Jim was a great feller to manage a catboat; for things has moved slower on the Cape than in many parts of the country.”

So Captain Jim Hubbell was engaged as sailor to the expedition; and when he came on to Sardis and looked over the Dipsey he expressed a general opinion of her construction and capabilities which indicated a disposition on his part to send her, and all others fashioned after her plan, to depths a great deal lower than ever had been contemplated by their inventors. Still, as he wanted very much to go to the pole if it was possible that he could get there, and as the wages offered him were exceedingly liberal, Captain Jim enlisted, in the party. His duties were to begin when the Dipsey floated on the surface of the sea like a commonsense craft.
