Beyond this, the doctor had ordered four tanks built from sheet metal a sixth of an inch thick; they were connected to each other by pipes equipped with spigots; attached to them was a coil made of two-inch-wide tubing that ended in two straight, different-sized extensions, the longer measuring 25 feet in height, the shorter just 15 feet.
The sheet-metal tanks were fitted into the gondola in such a way as to take up the least possible space; the coil didn’t need to be eased in until later and was packed separately, as was a very powerful Bunsen battery. This mechanism had been so cleverly put together, it weighed no more than 700 pounds, even with its special 25-gallon water tank.
The instruments set aside for the journey consisted of two barometers, two thermometers, two compasses, a sextant, two chronometers, an artificial horizon, and an altazimuth, a telescope for surveying things far away and out of reach. The Greenwich Observatory had put itself at the doctor’s disposal. But Samuel didn’t propose to do any physics experiments; he simply wanted to work out his heading and fix the positions of the chief rivers, mountains, and towns.
He also took along three well-tested iron anchors, likewise a 50-foot ladder of light, tough silk.
He calculated as well the exact weight of his provisions; they consisted of tea, coffee, crackers, salted meat, and pemmican, a mixture that contains many nourishing ingredients in concentrated form. In addition to an adequate supply of brandy, he arranged for two water tanks that held 22 gallons apiece.3
Consuming these various foods would gradually lower the weight that their lighter-than-air vehicle had to carry—because it’s essential to realize that a balloon’s buoyancy in the air is tremendously sensitive. Even an almost unnoticeable weight loss is enough to cause a distinct change in her handling.
The doctor didn’t forget to bring a tent for covering part of the gondola, nor the blankets that would make up their entire bedding for the journey, nor some hunting rifles, nor supplies of gunpowder and bullets.
Here’s a summary of his different calculations:
This was the breakdown of the 4,000 pounds that Dr. Fergusson proposed to carry aloft; he brought just 200 pounds of ballast “for unexpected developments only,” he said, because he definitely intended not to use any … thanks to the presence of his mechanism.
* These dimensions are nothing extraordinary: in Lyon back in 1784, Monsieur Montgolfier built a lighter-than-air vehicle with a capacity of 340,000 cubic feet, and she could heft a weight of twenty-two tons.2

Joe’s value—the Resolute’s commander—arrangements1—Kennedy’s arsenal—the farewell dinner—departure on February 21—science sessions with the doctor—Duveyrier, Livingstone—specifics of air travel—Kennedy reduced to silence.
By about February 10 preparations were nearing completion, and the envelopes, one inside the other, were totally finished; their walls had been subjected to intense air pressure and had passed the test; this spoke well for their strength and bore witness to their painstaking manufacture.
Joe was beyond happiness; he beat a steady path from Greek St. to the Mitchells’ workshop, always bustling and beaming, eager to give the details of the business to anybody who didn’t ask, prouder than ever of going with his master. I even think that in showing off the lighter-than-air vehicle, talking up the doctor’s ideas or designs, and pointing him out through a partly open window or on his way down the street, the worthy lad earned a half-crown or two; but there’s no need to wrinkle your nose; he had every right to turn a little profit on the wonderment and curiosity of his age.
On February 16 the Resolute arrived and dropped anchor off Greenwich. A local vessel of some 860 tons burden,2 she was propeller driven, made good time, and had been entrusted with replenishing Sir James Clark Ross’s supplies during his latest expedition to the polar regions. By reputation Commander Pennet was a genial chap, and he took a special interest in this journey, being a longtime fan of the doctor’s. This Pennet fellow was more of a scholar than a soldier, which didn’t keep his ship from carrying four short-bodied naval cannons, although they had never harmed a soul and went off only during peacetime ceremonies.
The Resolute’s hold had been arranged explicitly to house the lighter-than-air vehicle; she was loaded on board with the greatest care during the day of February 18; to avert any accidents, they stowed her deep in the ship; under Fergusson’s eyes they also lashed down the gondola and its accessories—the anchors, lines, and provisions, plus the water tanks that were to be filled on arrival.
To produce the hydrogen gas, they took on board ten barrels of sulfuric acid and ten of ground scrap iron. These amounts were more than enough, but it was essential to guard against possible losses. The mechanism designed for expanding the gas included some thirty casks, and the whole works were stowed deep in the hold.
These various preparations were complete by the evening of February 18. Two comfortably furnished cabins were waiting for Dr. Fergusson and his friend Kennedy. Swearing that he wasn’t going, the Scot made his way on board with an authentic hunter’s arsenal—two fine breech-loading, double-barreled shotguns and a top-of-the-line rifle from the factory of Purdey, Moore and Dickson in Edinburgh; with a weapon like this, a hunter wouldn’t be hard pressed to put a bullet in a mountain goat’s eye at 2,000 paces; in addition he had two Colt six-shooters for sudden surprises; his powder supply, cartridge pouch, shot, and bullets were ample for his needs but didn’t exceed the weight limits spelled out by the doctor.
The three travelers took up residence on board during the day of February 19; they were welcomed with pomp and circumstance by the captain and his officers, the doctor as cool as ever and concerned strictly with his expedition, Dick excited but trying not to show it, Joe bounding around and bursting with smart-aleck remarks; he quickly became the wit of the wardroom, where they saved him a place.
On February 20 the Royal Geographical Society threw a big farewell dinner for Dr. Fergusson and Kennedy. Commander Pennet and his officers were in attendance at this meal, which was very lively and heavily given over to toasting and well wishing; they drank to each other’s health and longevity often enough to guarantee every guest centuries of existence. Sir Francis M—— presided with emotional restraint, dignified as ever.
Much to his befuddlement, Dick Kennedy received a good share of these bacchic congratulations. After drinking to “Fergusson the fearless, the glory of all England,” they just had to drink to “Kennedy the courageous, his no-less-daring companion.”
Dick turned beet red, which they took for modesty: the clapping increased. Dick turned redder still.
A message from the Queen arrived during dessert; she presented her compliments to the two travelers and wished them every success in their undertaking.
Which called for a new round of toasts “to Her Most Gracious Majesty.”
At midnight, after fervent farewells and hearty handshakes, the guests took their leave.
The Resolute’s longboats were waiting by Westminster Bridge; the commander
