which was ninety-seven feet high by sixty-seven feet in diameter. It was made of three thicknesses of silk, and varnished over twice, inside and out. It was handled by means of valves. The whole balloon was covered with a network of hemp, ending in forty-eight suspension ropes, to which the wooden bearing ring was attached.
The car, shaped like a cylinder and made of wicker, was covered with tarpaulin, and was intended for rest and sleep. The place for work and observation was a swinging gallery, which also served for the roof of the car. In this gallery the scientific instruments were kept. Andrée took with him thermometers, barometers, cameras, and every sort of needful apparatus. The car contained a sleeping bag, and stores of books, maps, toilet articles, arms, and ammunition. The balloon was built to carry three passengers. While one slept, the other two expected to remain on the roof, taking observations and guiding the balloon.
The bearing ring was the main storeroom. Crosspieces of wood formed a floor, upon which many necessary articles were packed. Boats, sledges, sails, ropes, and provisions of all kinds were stored away in forty-eight large sacks, which were hung to the bearing ring. Andrée had provisions enough to last for nine months, and everything was packed so as to occupy as little space as possible.
Three sails and three guide ropes were arranged to aid in steering the balloon. The long guide ropes trailed behind the balloon, serving the purpose of a rudder. The sails caught the wind, increased the speed, and permitted change of direction.
In 1896, the balloon and all the supplies were taken to Dane's island, near Spitzbergen, but as the desired south wind did not blow, Andrée returned to Sweden. In May, 1897, Andrée and his companions again went to Dane's
