(6 x 10 inches), almost at right angles to the ship’s sides, and securely fastened to the sides and to the beams by wooden knees. There are 68 of these stays distributed over the ship. In addition, there are under the beams three rows of vertical stanchions between decks, and one row in the lower hold from the keelson. These are connected to the keelson, to the beams, and to each other by iron bands. The whole of the ship’s interior is thus filled with a network of braces and stays, arranged in such a way as to transfer and distribute the pressure from without, and give rigidity to the whole construction. In the engine and boiler room it was necessary to modify the arrangement of stays, so as to give room for the engines and boiler. All the iron, with the exception of the heaviest forgings, is galvanized.

When Otto Sverdrup was to use the Fram for his Polar expedition, he had a number of alterations carried out. The most important of these consisted in laying a new deck in the fore part of the ship, from the bulkhead forward of the engine-room to the stem, at a height of 7 feet 4 inches (to the upper side of the planks) above the old fore-deck. The space below the new deck was fitted as a fore-cabin, with a number of state-rooms leading out of it, a large workroom, etc. The old chart-house immediately forward of the funnel was removed, and in its place a large water-tank was fitted. The foremast was raised and stepped in the lower deck. A false keel, 10 inches deep and 12 inches broad, was placed below the keel. A number of minor alterations were also carried out.

After the Fram returned in 1902 from her second expedition under Captain Sverdrup, she was sent down to Horten to be laid up in the Naval Dockyard.

Not long after the vessel had arrived at the dockyard, Captain Sverdrup proposed various repairs and alterations. The repairs were carried out in part, but the alterations were postponed pending a decision as to the future employment of the vessel.

The Fram then lay idle in the naval harbour until 1905, when she was used by the marine artillery as a floating magazine. In the same year a good deal of the vessel’s outfit (amongst other things all her sails and most of her rigging) was lost in a fire in one of the naval storehouses, where these things were stored.

In 1903 the ship’s keel and stem (which are of elm and oak) were sheathed with zinc, while the outer sheathing (ice-skin), which is of greenheart, was kept coated with coal-tar and copper composition. In 1907 the whole outer sheathing below the waterline was covered with zinc; this was removed in 1910 when the ship was prepared for her third commission under Roald Amundsen.

In 1907 a thorough examination of the vessel was made, as it was suspected that the timber inside the thick cork insulation that surrounded the cabins had begun to decay.

On previous expeditions the cabins, provision hold aft, and workrooms forward of the fore-cabin, had been insulated with several thicknesses of wooden panelling. The interstices were filled with finely-divided cork, alternately with reindeer hair and thick felt and linoleum. In the course of years damp had penetrated into the non-conducting material, with the result that fungus and decay had spread in the surrounding woodwork. Thus it was seen during the examination in 1907

that the panelling and ceiling of the cabins in question were to a great extent rotten or attacked by fungus. In the same way the under side of the upper deck over these cabins was partly attacked by fungus, as were its beams, knees, and carlings. The lower deck, on the other hand, was better preserved. The filling-in timbers of spruce or fir between the frame-timbers in the cabins were damaged by fungus, while the frame-timbers themselves, which were of oak, were good. The outer lining outside the insulated parts was also somewhat damaged by fungus.

In the coal-bunkers over the main-deck the spruce knees were partly rotten, as were some of the beams, while the lining was here fairly good.

The masts and main-topmast were somewhat attacked by decay, while the rest of the spars were good.

During and after the examination all the panelling and insulation was removed, the parts attacked by fungus or decay were also removed, and the woodwork coated with carbolineum or tar. The masts and various stores and fittings were taken ashore at the same time.

It was found that the rest of the vessel-that is, the whole of the lower part of the hull right up to the cabin deck-was perfectly sound, and as good as new. Nor was there any sign of strain anywhere. It is difficult to imagine any better proof of the excellence of the vessel’s construction; after two protracted expeditions to the most northern regions to which any ship has ever penetrated, where the vessel was often exposed to the severest ice-pressure, and in spite of her being (in 1907) fifteen years old, the examination showed that her actual hull, the part of the ship that has to resist the heavy strain of water and ice, was in just as good condition as when she was new.

The vessel was then left in this state until, as already mentioned, Roald Amundsen and her builder, Colin Archer, came down to the dockyard on June 1, 1908, and with the necessary assistance made an examination of her.

After some correspondence and verbal conferences between Roald Amundsen and the dockyard, the latter, on March 9, 1909, made a tender for the repairs and alterations to the Fram. The repairs consisted of making good the damage to the topsides referred to above.

The alterations were due in the first instance to the circumstance that the steam-engine and boiler (the latter had had its flues burnt out on Sverdrup’s expedition) were to be replaced by an oil-motor; as a consequence of this the coal-bunkers would disappear, while, on the other hand, a large number of oil-tanks, capable of containing about 90 tons of oil, were to be put in. It was also considered desirable to rig squaresails on the foremast in view of the great distances that were to be sailed on the proposed expedition.

The present arrangement of the vessel will best be followed by referring to the elevation and plan (Figs. 1 and 2).

In the extreme after-part of the lower hold is placed the 180

horse-power Diesel engine, surrounded by its auxiliary machinery and air-reservoirs.

In addition, some of the tanks containing the fuel itself are placed in the engine-room (marked O); the other tanks shown in the engine-room (marked 9) serve for storing lubricating oil. The existing engine-room was formerly the engine and boiler room, with coal-bunkers on both sides in the forward part. Forward of the watertight bulkhead of the engine-room we have, in the lower hold, the main store of oil-fuel, contained in tanks (marked O) of various sizes, on account of their having to be placed among the numerous diagonal stays. The tanks are filled and emptied by means of a pump and a petroleum hose through a manhole in the top, over which, again, are hatches in the deck above; no connecting pipes are fitted between the different tanks, for fear they might be damaged by frost or shock, thus involving a risk of losing oil. The main supply tank for fuel is placed over the forward side of the engine-room, where it is supported on strong steel girders; inside this tank, again, there are two smaller ones — settling tanks — from which the oil is conveyed in pipes to the engine-pumps. The main tank is of irregular shape — as will be seen from the drawing — since a square piece is taken out of its starboard after-corner for a way down into the engine-room. Besides this way down, an emergency way leads up from the engine-room, right aft, to one of the after-cabins. The oil hold is closed forward by a watertight bulkhead, which goes up to the main-deck. The hold forward of the oil-supply is unaltered, and serves for stowing cargo (mainly provisions), as does the hold above the oil-supply and below the main-deck.

On the main-deck right aft we now find a space arranged on each side of the well for the propeller and rudder; the lower part of this space is occupied by two tanks for lamp-oil, and above the tanks is a thin partition, which forms the floor of two small sail-rooms, with hatches to the deck above. Around the mizzenmast is the after-saloon, with eight cabins leading out of it. From the forward end of the after-saloon two passages lead to the large workroom amidships. These passages run past what were formerly coal-bunkers, but are now arranged as cabins, intended only to be used in milder climates, as they are not provided with any special insulation. From the port passage a door leads to the engine-room companion. In the after-part of the large workroom is the galley. This room is entirely lined with zinc, both on walls and ceiling (on account of the danger of fire), while the deck is covered with lead, on which tiles are laid in cement. Forward of the galley is the main hatch, and two large water-tanks are fitted here, one on each side. The remainder of the workroom affords space for carpenter’s benches, turning-lathes, a forge, vices, etc. From the workroom two doors lead into the fore-saloon with its adjoining cabins. Amundsen’s cabin is the farthest forward on the starboard side, and communicates with an instrument-room. From the fore-saloon a door leads out forward, past a sixth cabin.

In the space forward on the main-deck we have the fore-hatch, and by the side of this a room entirely lined with zinc plates, which serves for storing furs. Forward of the fur store is fitted a 15

horse-power one-cylinder Bolinder motor for working the capstan; the main features of its working will be seen in the drawing. There are two independent transmissions: by belt and by chain. The former is usually employed. The chain transmission was provided as a reserve, since it was feared that belt-driving might prove unserviceable in a cold climate. This fear, however, has hitherto been ungrounded.

Forward of the motor there is a large iron tank to supply water for cooling it. In the same space are chain-pipes to the locker below and the heel of the bowsprit. This space also serves as cable-tier.

On the upper deck we find aft, the opening of the rudder-well and that of the propeller-well, covered with gratings. A piece was added to the lower part of the rudder to give more rudder area.

Forward of the propeller-well comes the reserve steering-gear, almost in the same position formerly occupied by the only steering-gear; the ordinary steering-gear is now moved to the bridge. The old engine-room companion aft is now removed, and forward of the after-wheel is only the skylight of the after-saloon. Up through the latter comes the exhaust-pipe of the main engine. Forward of and round the mizzenmast is the bridge, which is partly formed by the roofs of the large chart-house and laboratory amidships and the two houses on each side. The chart-house occupies the place of the old boiler-room ventilator, and abuts on the fore-deck. (It is thus a little aft of the place occupied by the chart-house on Nansen’s expedition.) It is strongly built of timbers standing upright, securely bolted to the deck. On both sides of this timber work there are panels, 2 inches thick on the outside and 1 inch on the inside, and the space between is filled with finely-divided cork. Floor and roof are insulated in a similar way, as is also the door; the
