The first time that poisoned meat was put out it was left untouched. Some good meat was added, and at once disappeared, though the pieces containing poison were still left alone. The poisoned baits were then taken up, and only good meat put down, the wolves always taking it until, their confidence being aroused, a few poisoned baits were mixed with the other. The experiment succeeded so well that when the baits were next visited four wolves and one fox were found dead. The others, evidently alarmed, made off and did not again return. As October passed the phenomena of the solar halo and aurora began to make their appearance. The observation of atmospheric conditions being one of the objects of the expedition, great attention was paid to these displays, and some excellent descriptions were given of them. One which occurred on October 21 and lasted five hours is thus described by the leader of the expedition:-- "It consisted of two concentric rings, distant 23° and 46° respectively from the sun, which were marked by five mock suns where the rainbow tints were most clearly displayed. This was followed at evening by the first aurora display, in the form of a delicate convoluted ribbon of colourless light. On the 24th there was another halo. This was a double one, there being two perfect concentric half-circles, distant 23° and 46° from the sun, each half-circle having a contact arch of magnificent clearness. No fewer than six mock suns appeared, two on either hand and two above the real sun, with prismatic colours in each case as vivid, and clear as in any rainbow, the heavens being filled with a great glow and wealth of colour." After the sun had gone and the twilight of the long winter night had set in, the sky was vivid, at one time, with a wide sweep of red, yellow, and blue, marked by bars of white light running up and down. Later, when the moon had risen, further atmospheric marvels were recorded. On one occasion the moon was surrounded by two circles, 22° and 46° above the horizon. Both were topped by contact arches, and within them six mock moons were present, two on each side of the true moon, and two directly above it, all of which were brilliant with the colours of the rainbow. Spires of light proceeded from the moon vertically, reaching downwards to the horizon, and upwards to the outer circle. In addition to these, a brilliant streak of white clear light extended from the moon, horizontally, on both sides, completely round the horizon, and now and again a faint mock moon of rainbow colours appeared high over the whole, and another very low under it, making eight mock moons all visible at the same moment round the real one. The moon was also seen surrounded by a corona of four distinct bands of coloured light, the first white, the second yellow, the third blue, and the outer one red.
