All preparations were completed by the summer of 1896, and on June 7th the party embarked at Gothenburg with all necessaries on board, arriving at Spitzbergen on June 21st. Andree, who was to be accompanied on his aerial voyage by two companions, M. Nils Strindberg and Dr. Ekholm, spent some time in selecting a spot that would seem suitable for their momentous start, and this was finally found on Dane's Island, where their cargo was accordingly landed. The first operation was the erection of a wooden shed, the materials for which they had brought with them, as a protection from the wind. It was a work which entailed some loss of time, after which the gas apparatus had to be got into order, so that, in spite of all efforts, it was the 27th of July before the balloon was inflated and in readiness. A member of an advance party of an eclipse expedition arriving in Spitzbergen at this period, and paying a visit to Andree for the purpose of taking him letters, wrote:--"We watched him deal out the letters to his men. They are all volunteers and include seven sea captains, a lawyer, and other people some forty in all. Andree chaffed each man to whom he gave a letter, and all were as merry as crickets over the business.... We spent our time in watching preparations. The vaseline (for soaking the guide ropes) caught fire to-day, but, luckily no rope was in the pot." But the wind as yet was contrary, and day after day passed without any shift to a favourable quarter, until the captain of the ship which had conveyed them was compelled to bring matters to an issue by saying that they must return home without delay if he was to avoid getting frozen in for the winter. The balloon had now remained inflated for twenty-one days, and Dr. Ekholm, calculating that the leakage of gas amounted to nearly 1 per cent. per day, became distrustful of the capability of such a vessel to cope with such a voyage as had been aimed at. The party had now no choice but to return home with their balloon, leaving, however, the shed and gas-generating apparatus for another occasion. This occasion came the following summer, when the dauntless explorers returned to their task, leaving Gothenburg on May 28th, 1897, in a vessel lent by the King of Sweden, and reaching Dane's Island on the 30th of the same month. Dr. Ekholm had retired from the enterprise, but in his place were two volunteers, Messrs. Frankel and Svedenborg, the latter as "odd man," to fill the place of any of the other three who might be prevented from making the final venture.
