I employed part of the day in making a fox-trap, consisting simply of a box closed on one side by a metal grating, and on the other by a sliding door. This latter would close automatically when the animal touched it, a bird fastened to the bottom of the cage serving as a bait. In the evening I tried the sledges which were to be taken in the balloon. I harnessed myself to one of them, and took my trap half a league away to the hills, where I set it so as to be able to observe it from the _Svensksund_, whence I could see by means of a telescope when the door of the cage was shut. I had not long to wait; the next morning the cage was closed. I went up to the mountain, and soon perceived through the grating of the cage a cunning little head and two bright eyes, which were attentively watching all my movements. The prisoner was a young fox; there were several species of them at Spitzbergen. We had already seen three kinds: one was a fine glossy black, another silvery white, and a third had yellow and brown spots. The little captive belonged to this last category. Seeing himself discovered, my fox darted against the grating, growling at my approach and showing his pretty little sharp teeth. With many precautions, putting my hands through the bars of the cage, I succeeded in muzzling him and in tying his paws together with cords. Having thus made it impossible for him to do any harm, I led him over the snow to Pike House, where my arrival with my prisoner at the end of a long string excited much curiosity and caused considerable mirth. I hoped to take this young fox back to France. He was put in a cage, where he received many visits from persons interested; one of the latter not having closed the door with sufficient care, the Spitzbergen fox, in no way inferior to those of our own country in point of cunning, succeeded in opening it and recovered his liberty. He was even seen to pause ironically for a few moments in front of the balloon shed, where the changes that had been made seemed to interest him. IV The Landing and Preparation of the Balloon—The Inflation _June 12th._—Two weeks had elapsed since our arrival at Dane’s Island. The work connected with the shed had been pressed forward, and as Andrée had announced, the shed was ready to receive the balloon. A large canvas tent, made in eight equal sections, was fixed over its entire circumference half-way up the shed; it was drawn up in the centre by the aid of pulleys connected with the top of the building. We were thus comfortably sheltered from snow or rain whilst getting the balloon ready. The unloading of the _Virgo_ was finished, and the ship was ready to start as soon as the ice should disperse. We went on board to drink coffee and take a parting glass of punch.
