Mr Banks and Dr Solander, while they were improving an opportunity which they had, with so much danger and difficulty, procured, by gathering the plants which they found upon the mountain, sent Mr Green and Mr Monkhouse back to Mr Buchan and the people that were with him, with directions to bring them to a hill, which they thought lay in a better route for returning to the wood, and which was therefore appointed as a general rendezvous.  It was proposed, that from this hill they should push through the swamp, which seemed by the new route not to be more than half a mile over, into the shelter of the wood, and there build their wigwam, and make a fire:  This, as their way was all down hill, it seemed easy to accomplish.  Their whole company assembled at the rendezvous, and, though pinched with the cold, were in health and spirits, Mr Buchan himself having recovered his strength in a much greater degree than could have been expected.  It was now near eight o’clock in the evening, but still good day-light, and they set forward for the nearest valley, Mr Banks himself undertaking to bring up the rear, and see that no straggler was left behind:  This may perhaps be thought a superfluous caution, but it will soon appear to be otherwise.  Dr Solander, who had more than once crossed the mountains which divide Sweden from Norway, well knew that extreme cold, especially when joined with fatigue, produces a torpor and sleepiness that are almost irresistible:  He therefore conjured the company to keep moving, whatever pain it might cost them, and whatever relief they might be promised by an inclination to rest:  Whoever sits down, says he, will sleep; and whoever sleeps, will wake no more.  Thus, at once admonished and alarmed, they set forward; but while they were still upon the naked rock, and before they had got among the bushes, the cold became suddenly so intense, as to produce the effects that had been most dreaded.  Dr Solander himself was the first who found the inclination, against which he had warned others, irresistible; and insisted upon being suffered to lie down.  Mr Banks entreated and remonstrated in vain, down he lay upon the ground, though it was covered with snow; and it was with great difficulty that his friend kept him from sleeping.  Richmond also, one of the black servants, began to linger, having suffered from the cold in the same manner as the doctor.  Mr Banks, therefore, sent five of the company, among whom was Mr Buchan, forward to get a fire ready at the first convenient place they could find; and himself, with four others, remained with the doctor and Richmond, whom, partly by persuasion and entreaty, and partly by force, they brought on; but when they had got through the greatest part of the birch and swamp, they both declared they could go no farther.  Mr Banks had recourse again to entreaty and expostulation, but they produced no effect:  When Richmond was told, that if he did not go on he would in a short time be frozen to death, he answered,
