Seeing the man well out of sight, Craft and Hathaway carefully made their way back to the statue, and were soon inside of the pedestal. The slab door was then nearly closed, leaving but a slight aperture for the entrance of air, the opening covered by boxes, to prevent the rays of their lights being seen by any chance visitors to that neighborhood.
During their absence, Cobb had taken out two lanterns from one of the boxes, and now a bright light made everything quite clear within the chamber.
“Now,” said Cobb to Hathaway, “take that hatchet and open all of the boxes.”
The lids were quickly torn off and thrown to one side.
The contents of these boxes needed careful inspection. The large one was first emptied. The sides of this box were wrenched off, disclosing a large glass case, seven feet six inches by two feet eight inches, and sixteen inches in height. This glass coffin – for such, indeed, it resembled – was carefully taken out and set upon the floor. Then followed, from the same box, an ordinary set of single bed-springs, or woven-wire mattress, such as are used on single beds. Cobb then took from one of the smaller boxes a pair of iron horses or trestles, and placed them in one corner of the room, with their legs firmly fixed into the cemented floor. Carefully lifting the glass case, he and Craft set it upon the trestles, leaving a space of about thirty inches between it and the floor. Next they hinged the wire mattress to the trestles, so that there were full twenty inches between it and the bottom of the glass case. From the next box unpacked were taken seventy-five cells of Grenet battery. These cells were of peculiar construction, and differed from the regular style in that the zincs were drawn up and held clear of the electropoion fluid by slight fastenings, which terminated in glass bulbs blown in the tops. Cobb had selected this battery on account of its great strength, and for the reason that it would remain inactive for an indefinite time, provided the zincs were kept out of the fluid. Placing an iron stand near the head of the case, he and Hathaway arranged the jars upon it, and connected the various cells for intensity.
The wires were then run through small holes in the top glass of the large case, being insulated with a special covering that would withstand age without deteriorating.
The next thing was to set in position, over the row of battery cells, an iron beam, with a fall of about four inches, the fall terminating in two sockets. This beam was held over and in position by a pulley, over which ran a wire rope composed of aluminum strands, and having attached to it a fifty-pound weight. Connected to the two poles of the battery were insulated wires, terminating in flat discs of copper.
These wires were about thirty feet long, and passed through the holes in the top of the glass case, the copper discs being inside.
From another box were taken two bottles of fine old French brandy, two bottles of whisky, a small bottle of Valentine’s beef juice, and several cans of preserved meats, which had been prepared by Cobb, and the cans made of aluminum for the purpose. An alcohol heater was also taken out and set up in such a manner that a glass reservoir could, upon being turned on, feed it with alcohol. Through this heater ran wires joined to a platinum strip and connected with twenty cells of the battery. A cup and saucer, knife, fork, can-opener, spoon, and a couple of stew-pans, were next taken out and laid by the heater.
All these things having been put in order, Cobb, with the assistance of Hathaway, carefully lifted from a large box a heavy glass case, two feet nine inches high by three feet square. This case was set in the further corner of the chamber.
Through a door in the top, which Cobb opened, both Craft and Hathaway saw a number of wheel and pinion works, while at the bottom of the case was a circular piece of bright aluminum divided into equal divisions. The center of the ring was sunk into the glass bottom half an inch, and on one side of the ring was a number of small wheels and rods; the whole presenting the aspect of very fine and delicate mechanism.
Cobb now took out of the last box a large and very elegant compass, two feet in diameter and with a heavy needle; this he placed in the sunken center of the glass case.
Craft noticed that there was no iron or steel in the works in this box; nothing but aluminum, save the needle itself.
Through the sides of the case, Cobb adjusted an aluminum rod connecting with the pulley and weight attached to the beam over the batteries.
By this time the needle in the compass had settled and the positive pole pointed to 283 on the aluminum scale.
Both Craft and Hathaway had asked but few questions during all this work, curbing their curiosity until such time as their companion would enlighten them as to the meaning of all this apparatus. They had been on the point, a number of times, of asking for some information, but the other had, by a look, quickly given them to understand that he was not yet ready to explain things. But it was impossible for Craft to hold in any longer; he had to ask the use of this last glass case, with its many wheels and delicate machinery.
“Wait! You will understand it all soon,” answered Cobb. “There is little more to do to-night.” Then, taking a paper from his pocket, he scanned it for fully five minutes, making a few notes upon it with his pencil during the time.
At last, seeming satisfied, he bent over the compass in the box, and by a small screw in its side turned the whole delicately adjusted works around until a fine pointer, from which projected a tiny hook, became flush with the figures 260 from the zero of the scale, or to a reading of 4 degrees 20 minutes; then turning the whole compass-box around, he carefully adjusted it so that the needle should point exactly to the figures 993, equivalent to a reading of 16 degrees 33 minutes, the magnetic variation east, of San Francisco, California, in December, 1887.
It was easy to see that the little hook which hung down from the overlapping works would become engaged with the needle of the compass if the latter were to retrograde in arc 12 degrees 13 minutes.
Unscrewing a cap on the top of the case, he applied a small air-pump, which he had taken out of the box, to the opening, and screwed it firmly on; then, closing the glass door, he placed cement along the junction of the door and sides, from a bottle which he had brought for that purpose. In a few moments, the cement had set, and then, working the air-pump, he soon exhausted the air from the case; finally unscrewing the pump, he replaced the cap and laid the pump in the corner of the chamber.
All this being finished to his satisfaction, he announced that the work for the night was completed.
Looking at his watch, Cobb said:
“It is now four o’clock in the morning, and time that we should get out of this if we don’t wish to be seen departing. We have done all that it is possible to do for the present; let us at once start for town; besides, you have to be at the post by six o’clock.”
“Yes, that is true,” returned Hathaway; “we are due at that hour. We have done a good deal of work, but for the life of me, I am totally ignorant of the purposes of all this apparatus. I would like to have you explain some of it to me,” and his eyes turned inquiringly toward the large case with its wheels and compass.
“All in good time!” and Cobb cautiously opened the swinging panel.
The coast was clear; not a single person was in sight.
“Now, then, be lively!” and he stepped out, the others following quickly. In another moment the door was closed, and not a sign was left to indicate that the pedestal of the Statue of Liberty held within its interior the apparatus necessary for prolonging the life of a human being.
The three friends passed down the hill, and took the Haight-street cars for the city. It was the first car for the day, and not another passenger was on board.
Arriving at the Occidental, Cobb said:
“You are expected to be at reveille this morning, but I have no duties until retreat. There are a few things that I wish to attend to; so I will leave you here. Be sure to be at my quarters at 9:30 to-night. Good-bye!” and he left them without waiting for a reply.
It was nearly eight o’clock, and after a hearty breakfast, when Cobb left the hotel, passed down Montgomery street into Washington, and made his way to a small-sized house at the foot of an alley
