When he had returned to Cape Tariff, after parting with the Dipsey, he had received several messages from Sammy, which assured him that the submarine voyage was proceeding satisfactorily. But when he went on board the Go Lightly and started homeward, he would be able to hear nothing more from the submarine voyagers until he reached St. John's, Newfoundland—the first place at which his vessel would touch. Of course constant communication with Sardis would be kept up, but this communication might be the source of great danger to the plans of Roland Clewe. Whatever messages of importance came from the depths of the arctic regions he wished to come only to him or to Mrs. Raleigh. He had contrived a telegraphic cipher, known only to Mrs. Raleigh, Sammy, and two officers of the Dipsey, and, to insure secrecy, Sammy had been strictly enjoined to send no information in any other way than in this cipher.

For years there had been men, both in America and in Europe, who had been watching with jealous scrutiny the inventions and researches of Roland Clewe, and he well understood that if they should discover his processes and plans before they were brought to successful completion he must expect to be robbed of many of the results of his labors. The first news that came to him on his recent return to America had been the tale told by Sammy Block, of the man in the air who had been endeavoring to peer down into his lens-house, and he had heard of other attempts of this kind. Therefore it was that the telegraphic instrument on the Dipsey had been given into the sole charge of Samuel Block, who had become a very capable operator, and who could be relied upon to send no news over his wire which could give serviceable information to the operators along the line from Cape Tariff to Sardis, New Jersey.

But Clewe did not in the least desire that Margaret Raleigh should be kept waiting until he came back from the arctic regions for news from the expedition, which she as well as himself had sent out into the unknown North. Consequently Samuel Block had been told that he might communicate with Mrs. Raleigh as soon and as often as he pleased, remembering always to be careful never to send any word which might reveal anything to the detriment of his employers. When a message should be received on board the Dipsey that Mr. Clewe was ready to communicate with her, frequent reports were expected from the Master Electrician, but it would be Sammy who would unlock the cover which had been placed over the instrument.

Before he retired to his bunk on the first night on board the Dipsey, Sammy thought it proper to send a message to Mrs. Raleigh. He had not telegraphed before because he knew that Mr. Clewe would communicate fully before he left Cape Tariff.

Margaret Raleigh had gone to bed late, and had been lying for an hour or two unable to sleep, so busy was her mind with the wonderful things which were happening in the far-away polar regions—strange and awful things—in which she had such a direct and lively interest. She had heard, from Roland Clewe, of the successful beginning of the Dipsey's voyage, and before she had gone to her chamber she had received a last message from him on leaving Cape Tariff; and now, as she lay there in her bed, her whole soul was occupied with thoughts of that little party of people—some of them so well known to her—all of them sent out upon this perilous and frightful expedition by her consent and assistance, and now left alone to work their way through the dread and silent waters that underlie the awful ice regions of the pole. She felt that so long as she had a mind she could not help thinking of them, and so long as she thought of them she could not sleep.

Suddenly there was a ring at the door, which made her start and spring from her bed, and shortly a telegraphic message was brought to her by a maid. It was from the depths of the Arctic Ocean, and read as follows:

“Getting on very well. No motion. Not cold. Slight rheumatism in Sarah's shoulder. Wants to know which side of plasters you gave her goes next skin,

“SAMUEL BLOCK.”

An hour afterwards there flashed farther northward than ever current from a battery had gone before an earnest, cordial, almost affectionate message from Margaret Raleigh to Sarah Block, and it concluded with the information that it was the rough side of the plasters which should go next to the skin. After that Mrs. Raleigh went to bed with a peaceful mind and slept soundly.

Frequent communications, always of a friendly or domestic nature, passed between the polar sea and Sardis during the next few days. Mrs. Raleigh would have telegraphed a good deal more than she did had it not been for the great expense from Sardis to Cape Tariff, and Sarah Block was held in restraint, not by pecuniary considerations, but by Sammy's sense of the fitness of things. He nearly always edited her messages, even when he consented to send them. One communication he positively refused to transmit. She came to him in a great flurry.
