Upon one occasion he received the medicine from the Doctor with such formality, and wrapped it up in his rein-deer robe with such extraordinary carefulness, that it excited the involuntary laughter of Mr. Hood and myself. The old man smiled in his turn, and as he always seemed proud of the familiar way in which we were accustomed to joke with him, we thought no more upon the subject. But he unfortunately mentioned the circumstance to his wife, who imagined in consequence, that the drug was not productive of its usual good effects, and they immediately came to the conclusion that some bad medicine had been intentionally given to them. The distress produced by this idea, was in proportion to their former faith in the potency of the remedy, and the night was spent in singing and groaning. Next morning the whole family were crying in concert, and it was not until the evening of the second day that we succeeded in pacifying them. The old woman began to feel better, and her faith in the medicine was renewed.
While speaking of this family, I may remark that the daughter, whom we designated Green-stockings from her dress, is considered by her tribe to be a great beauty. Mr. Hood drew an accurate portrait of her, although her mother was averse to her sitting for it. She was afraid, she said, that her daughter's likeness would induce the Great Chief who resided in England to send for the original. The young lady, however, was undeterred by any such fear. She has already been an object of contest between her countrymen, and although under sixteen years of age, has belonged successively to two husbands, and would probably have been the wife of many more, if her mother had not required her services as a nurse.
The weather during this month, was the coldest we experienced during our residence in America. The thermometer sunk on one occasion to 57° below zero, and never rose beyond 6° above it; the mean for the month was -29°.7. During these intense colds, however, the atmosphere was generally calm, and the wood-cutters and others went about their ordinary occupations without using any extraordinary precautions, yet without feeling any bad effects. They had their rein-deer shirts on, leathern mittens lined with blankets, and furred caps; but none of them used any defence for the face, or needed any. Indeed we have already mentioned that the heat is abstracted most rapidly from the body during strong breezes, and most of those who have perished from cold in this country, have fallen a sacrifice to their being overtaken on a lake or other unsheltered place, by a storm of wind. The intense colds, were, however, detrimental to us in another way. The trees froze to their very centres and became as hard as stones, and more difficult to cut. Some of the axes were broken daily, and by the end of the month we had only one left that was fit for felling trees. By intrusting it only to one of the party who had been bred a carpenter, and who could use it with dexterity, it was fortunately preserved until the arrival of our men with others from Fort Providence.
A thermometer, hung in our bed-room at the distance of sixteen feet from the fire, but exposed to its direct radiation, stood even in the day-time occasionally at 15° below zero, and was observed more than once previous to the kindling of the fire in the morning, to be as low as 40° below zero. On two of these occasions the chronometers 2149 and 2151, which during the night lay under Mr. Hood's and Dr. Richardson's pillows, stopped while they were dressing themselves.
The rapid at the commencement of the river remained open in the severest weather, although it was somewhat contracted in width. Its temperature was 32°, as was the surface of the river opposite the house, about a quarter of a mile lower down, tried at a hole in the ice, through which water was drawn for domestic purposes. The river here was two fathoms and a half deep, and the temperature at its bottom was at least 42° above zero. This fact was ascertained by a spirit thermometer; in which, probably, from some irregularity in the tube, a small portion of the coloured liquor usually remained at 42° when the column was made to descend rapidly. In the present instance the thermometer standing at 47° below zero, with no portion of the fluid in the upper part of the tube, was let down slowly into the water, but drawn cautiously and rapidly up again, when a red drop at +42° indicated that the fluid had risen to that point or above it. At this period the daily visits of the sun were very short, and owing to the obliquity of his rays, afforded us little warmth or light. It is half past eleven before he peeps over a small ridge of hills opposite to the house, and he sinks in the horizon at half past two. On the 28th Mr. Hood, in order to attain an approximation to the quantity of terrestrial refraction, observed the sun's meridian altitude when the thermometer stood at 46° below zero, at the imminent hazard of having his fingers frozen.
He found the sextant had changed its error considerably, and that the glasses had lost their parallelism from the contraction of the brass. In measuring the error he perceived that the diameter of the sun's image was considerably short of twice the semi-diameter; a proof of the uncertainty of celestial observations made during these intense frosts. The results of this and another similar observation are given at the bottom of the page[3].
[3] "The observed meridian altitude of ☉ upper limb was 2° 52' 51". Temperature of the air [-45° 5']. By comparing this altitude, corrected by the mean refraction and parallax, with that deduced from the latitude which was observed in autumn, the increase of refraction is found to be 6' 50", the whole refraction, therefore, for the altitude 2° 52' 51" is 21' 49". Admitting that the refraction increases in the same ratio as that of the atmosphere at a mean state of temperature, the horizontal refraction will be 47' 22". But the diameter of the sun measured immediately after the observation, was only 27' 7", which shews an increase of refraction at the lower limb of 3' 29". The horizontal refraction calculated with this difference, and the above-mentioned ratio, is 56' 3", at the temperature -45° 5'. So that in the parallel 68° 42', where if there was no refraction, the sun would be invisible for thirty-four days, his upper limb, with the refraction 56' 3", is, in fact, above the horizon at every noon.
The wind was from the westward a moderate breeze, and the air perfectly clear. January 1st, 1821. Observed meridian altitude of ☉ lower limb 2° 35' 20". ☉ apparent diameter 29° 20'. For apparent altitude 2° 35' 20", the mean refraction is 16' 5" (Mackay's Tables), and the true, found as detailed above, is 20' 8": which increasing in the same ratio as that of the atmosphere, at a mean state of temperature, is 41' 19" at the horizon. But the difference of refraction at the upper and lower limbs, increasing also in that ratio, gives 55' 16" for the horizontal refraction. Temperature of the air -41°. Wind north, a light breeze, a large halo visible about the sun. January 15th, 1821.—Observed an apparent meridian altitude ☉ lower limb 4° 24' 57". ☉ apparent diameter 31' 5". For apparent altitude 4° 24' 57", the mean refraction is 10' 58" (Mackay's Tables), and the true, found as detailed above, is 14' 39", which, increasing in the same ratio as that of the atmosphere at a mean state of temperature, is 43' 57" at the horizon. But the difference of refraction between the upper and lower limbs increasing also in that ratio, gives 48' 30" for the horizontal refraction.
Temperature of the air -35°, a light air from the westward, very clear.
The extreme coldness of the weather rendered these operations difficult and dangerous; yet I think the observations may be depended upon within 30", as will appear by their approximate results in calculating the horizontal refraction; for it must be considered that an error of 30", in the refraction in altitude, would make a difference of several minutes in the horizontal refraction."—Mr. Hood's Journal.
