I carried myself a small barometer, a large knife and digger for plants, note-book, telescope, compass, and other instruments; whilst two or three Lepcha lads who accompanied me as satellites, carried a botanising box, thermometers, sextant and artificial horizon, measuring-tape, azimuth compass and stand, geological hammer, bottles and boxes for insects, sketch-book, etc., arranged in compartments of strong canvass bags.
Soon after sun-rise on the 7th, I took several azimuths, with four needles belonging to the azimuth compass, the mean result of which gave the variation 7° 56' E. At noon, our latitude, by observation, was 33° 22' S.: We were about three leagues from the shore; the northermost land in sight bore N. 19 E. and some lands which projected in three bluff points, and which, for that reason; I called Cape Three Points, bore S.W. distant five leagues.
Thursday, 3rd. A Fresh Trade wind and fair weather. Variation per Azimuth this Evening 0 degrees 47 minutes East, and at a little past 9 a.m. longitude in per sun and moon 33 degrees 0 minutes West of Greenwich. Wind East by South-East; course South 15 degrees West; distance 128 miles; latitude 14 degrees 51 minutes South, longitude 33 degrees 7 minutes West. Friday, 4th.
While the radio man was reporting, the instrument man on the team would line up the UFO and begin to call out the angles of elevation and azimuth. The timer would call out the time; the recorder would write all of this down. The command post, upon hearing the report of the UFO, would call the next patrol and tell them. They too would try to pick it up.
At noon, this land bore N. 8 E. the northermost land in sight N. 13 E. and Cape Hawke S. 37 W. Our latitude, by observation, was 32° 2' S. which was twelve miles to the southward of that given by the log; so that probably we had a current setting that way: By the morning amplitude and azimuth, the variation was 9° 10' E. During our run along the shore, in the afternoon, we saw smoke in several places, at a little distance from the beach, and one upon the top of a hill, which was the first we had seen upon elevated ground since our arrival upon the coast.
The Variation of the Compass by the mean of Several Azimuth taken this Evening 12 degrees 46 minutes, and in the Morning by the same Method 12 degrees 43 minutes West. This day's Log and Observed Latitude agree, which is not reconcilable to Yesterday. Exercised the People at Small Arms.
A geometrical square of iron, with an intercepted quadrant of five cubits, and divided into fifteen seconds. A quadrant of four cubits radius, shewing ten seconds, with an azimuth circle. Zodiacal armillaries of brass, with steel meridians, three cubits in diameter. A sextant of brass, kept together by screws, and capable of being taken to pieces for travelling with. Its radius was four cubits.
For this purpose he had with him an azimuth compass; but he found, that the needle differed very considerably in its position, even to thirty degrees; the variation being in some places more, in others less. Once the needle varied from itself no less than two points in the distance of fourteen feet. Mr.
"This is going to be a job, Mart," he went back to it as soon as they were seated in the airboat, flying toward "home." "I can nail them, with an increasing shift in azimuth, up to about thirty thousand light-years, but after that it gets awfully hard to get the right shift, and up around a hundred thousand it seems to be darn near impossible gets to be pure guesswork.
From these extracts it is evident that he was acquainted with the attraction, repulsion, and polarity of the magnet, the art of communicating those properties to iron, the variation of the magnetic needle; and there are even some indications that he was acquainted with the construction of the azimuth compass.
