begin at once to take samples of water, and with a headwind, north-east, we lay close-hauled for some days. We also had a pretty stiff breeze, which was another reason for delaying the soundings until the 17th.

For taking samples of water a winch is used, with a sounding-line of, let us say, 5,000 metres (2,734 fathoms), on which are hung one or more tubes for catching water; we used three at once to save time. Now, supposing water and temperatures are to be taken at depths of 300, 400, and 500 metres (164, 218, and 273 fathoms), Apparatus III. (see diagram) is first hung on, about 20 metres (10 fathoms) from the end of the line, where a small weight (a) hangs; then it is lowered until the indicator-wheel, over which the line passes, shows 100 metres (54 fathoms); Apparatus II. is then put on, and it is lowered again for another 100 metres, when Apparatus I. is put on and the line paid out for 300 metres (164 fathoms) — that is, until the indicator-wheel shows 500 metres (273 fathoms). The upper Apparatus (I.) is then at 300 metres (164 fathoms), No. II. at 400 metres (218 fathoms), and No. III. at 500 metres (273 fathoms). Under Apparatus I. and II. is hung a slipping sinker (about 8 centimetres, or 3 1/4 inches, long, and 3 centimetres, or 1 1/4 inches, in diameter). To the water-samplers are attached thermometers (b) in tubes arranged for the purpose.

The water-samplers themselves consist of a brass cylinder (c), about 38 centimetres (15 inches) long and 4 centimetres (1 1/2 inches) in diameter (about half a litre of water), set in a frame (d). At about the middle of the cylinder are pivots, which rest in bearings on the frame, so that the cylinder can be swung 180 degrees (straight up and down).

The cylinder, while being lowered in an inverted position, is open at both ends, so that the water can pass through. But at its upper and lower ends are valves, working on hinges and provided with packing. When the apparatus is released, the cylinder swings round, and these valves then automatically close the ends of the cylinder. The water that is thus caught in the cylinder at the required depth remains in it while it is being heaved up, and is collected in bottles. When the apparatus is released, the column of mercury in the thermometer is broken, and the temperature of the water is read at the same depth as the water is taken from.

The release takes place in the following manner: when all the cylinders have been lowered to the required depths, they are left hanging for a few minutes, so that the thermometers may be set at the right temperature before the column of mercury is broken. Then a slipping sinker is sent down the line. When this sinker strikes the first apparatus, a spring is pressed, a hook (e) which has held the cylinder slips loose, and the cylinder turns completely over (Apparatus I.). As it does this, the valves, as already mentioned, close the ends of the cylinder, which is fixed in its new position by a hook in the bottom of the frame. At the same instant the slipping sinker that hangs under Apparatus I. is released, and continues the journey to Apparatus II., where the same thing happens. It is then repeated with Apparatus III. When they are all ready, they are heaved in.

By holding one’s finger on the line one can feel, at all events in fairly calm weather, when the sinkers strike against the cylinders; but I used to look at my watch, as it takes about half a minute for the sinker to go down 100 metres.

The necessary data are entered in a book.

On the morning of the 17th, then, the sails were clewed up, and the Fram began to roll even worse than with the sails set. We first tried taking soundings with a sinker of 66 pounds, and a tube for taking specimens of the sea-bed. At 2,000 metres (1,093 fathoms) or more the line (piano wire) broke, so that sinker, tube, and over 2,000

metres of line continued their way unhindered to the bottom. I had thought of taking samples of water at 4,000, 3,000, and 2,000 metres (2,187, 1,639, 1,093 fathoms), and so on, and water-cylinders were put on from 0 to 2,000 metres. This, however, took six hours. Next day, on account of the heavy sea, only a few samples from 0 to 100 metres (54 fathoms) were taken. On the third day we made another attempt to get the bottom. This time we got specimens of the sea-bed from about 4,500 metres (about 2,500 fathoms); but the heaving in and taking of water samples and temperatures occupied eight hours, from 7 a.m. till 3 p.m., or a third part of the twenty-four hours. In this way we should want at least nine months on the route that had been laid down; but as, unfortunately, this time was not at our disposal, we at once gave up taking specimens of the bottom and samples of water at greater depths than 1,000 metres (546 fathoms). For the remainder of the trip we took temperatures and samples of water at the following depths: 0, 5, 10, 25, 50, 75, 100, 150, 200, 250, 300, 400, 500, 750, and 1,000 metres (0, 2 3/4, 5 1/2, 13 1/2, 27, 41, 54, 81, 108, 135, 164, 218, 273, 410, and 546 fathoms), in all, fifteen samples from each station, and from this time forward we went on regularly with one station every day. Finally, we managed to heave up two water-cylinders on the same line by hand without great difficulty. At first this was done with the motor and sounding-machine, but this took too long, and we afterwards used nothing but a light hand-winch. Before very long we were so practised that the whole business only took two hours.

These two hours were those we liked best of the twenty-four. All kinds of funny stories were told, especially about experiences in Buenos Aires, and every day there was something new. Here is a little yarn: One of the members of the expedition had been knocked down by a motor-car in one of the busiest streets; the car stopped and of course a crowd collected at once. Our friend lay there, wondering whether he ought not to be dead, or at least to have broken a leg, so as to get compensation. While he lay thus, being prodded and examined by the public, he suddenly remembered that he had half a dollar in his pocket. With all that money it didn’t matter so much about the compensation; up jumped our friend like an india-rubber ball, and in a second he had vanished in the crowd, who stood open-mouthed, gazing after the “dead” man.

Our speed on this cruise was regulated as nearly as possible so that there might be about 100 nautical miles between each station, and I must say we were uncommonly lucky in the weather. We made two fairly parallel sections with comparatively regular intervals between the stations; as regular, in any case, as one can hope to get with a vessel like the Fram, which really has too little both of sail area and engine power. The number of stations was 60 in all and 891 samples of water were taken. Of plankton specimens 190 were sent home. The further examination of these specimens in Norway will show whether the material collected is of any value, and whether the cruise has yielded satisfactory results.

As regards the weather on the trip, it was uniformly good the whole time; we had a good deal of wind now and then, with seas and rolling, but for the most part there was a fresh breeze. In the southeast trade we sailed for four weeks at a stretch without using the engine, which then had a thorough overhauling. At the same time we had a good opportunity of smartening up the ship, which she needed badly. All the iron was freed from rust, and the whole vessel painted both below and above deck. The decks themselves were smeared with a mixture of oil, tar and turpentine, after being scoured. All the rigging was examined. At the anchorage at Buenos Aires nearly the whole ship was painted again, masts and yards, the outside of the vessel and everything inboard, both deck-houses, the boats and the various winches, pumps, etc. In the engine-room everything was either shining bright or freshly painted, everything hung in its place and such order and cleanliness reigned that it was a pleasure to go down there. The result of all this renovating and smartening up was that, when we fetched up by the quay at Buenos Aires, the Fram looked brighter than I suppose she has ever done since she was new.

During the trip the holds were also cleaned up, and all the provisions re-stowed and an inventory made of them.

A whole suit of sails was completely worn out on this voyage; but what can one expect when the ship is being worked every single day, with clewing up, making fast and setting of sails both in calms and winds? This work every day reminded me of the corvette Ellida, when the order was “all hands aloft.” As a rule, though, it was only clewing up the sails that had to be done, as we always had to take soundings on the weather side, so that the sounding-line should not foul the bottom of the vessel and smash the apparatus. And we did not lose more than one thermometer in about nine hundred soundings.

On account of all this wear and tear of sails R�nne was occupied the whole time, both at sea and in Buenos Aires, in making and patching sails, as there was not much more than the leeches left of those that had been used, and on the approaching trip (to the Ice Barrier) we should have to have absolutely first-class things in the “Roaring Forties.”

June 30, 1911, is a red-letter day in the Fram’s history, as on that day we intersected our course from Norway to the Barrier, and the Franz thus completed her first circumnavigation of the globe. Bravo, Fram! It was well done, especially after the bad character you have been given as a sailer and a sea-boat. In honour of the occasion we had a better dinner than usual, and the Franz was congratulated by all present on having done her work well.

On the evening of July 29 St. Helena was passed. It was the first time I had seen this historic island. It was very strange to think that “the greatest spirit of a hundred centuries,” as some author has called Napoleon, should have ending his restless life on this lonely island of the South Atlantic.

On August 12, when daylight came, we sighted the little Martin Vaz Islands ahead, and a little later South Trinidad (in 1910 this island was passed on October 16). We checked our chronometers, which, however, proved to be correct. From noon till 2 p.m., while we were lying still and taking our daily hydrographic observations, a sailing ship appeared to the north of us, lying close-hauled to the south. She bore down on us and ran up her flag, and we exchanged the usual greetings; she was a Norwegian barque bound for Australia. Otherwise we did not see more than four or five ships on the whole voyage, and those were pretty far off:

Never since leaving Madeira (September, 1910) had we been troubled with animals or insects of any kind whatever; but when we were in Buenos Aires for the first time, at least half a million flies came aboard to look at the vessel. I hoped they would go ashore when the
