We were away by 10.30 yesterday. Walked to the Glacier Tongue with gloomy forebodings; but for one gust a beautifully bright inspiriting day. Seals were about and were frequently mistaken for the motors. As we approached the Glacier Tongue, however, and became more alive to such mistakes, we realised that the motors were not in sight. At first I thought they must have sought better surface on the other side of the Tongue, but this theory was soon demolished and we were puzzled to know what had happened. At length walking onward they were descried far away over the floe towards Hut Point; soon after we saw good firm tracks over a snow surface, a pleasant change from the double tracks and slipper places we had seen on the bare ice. Our spirits went up at once, for it was not only evident that the machines were going, but that they were negotiating a very rough surface without difficulty. We marched on and overtook them about 2 1/2 miles from Hut Point, passing Simpson and Gran returning to Cape Evans. From the motors we learnt that things were going pretty well. The engines were working well when once in tune, but the cylinders, especially the two after ones, tended to get too hot, whilst the fan or wind playing on the carburetter tended to make it too cold. The trouble was to get a balance between the two, and this is effected by starting up the engines, then stopping and covering them and allowing the heat to spread by conductivity – of course, a rather clumsy device. We camped ahead of the motors as they camped for lunch. Directly after, Lashly brought his machine along on low gear and without difficulty ran it on to Cape Armitage. Meanwhile Day was having trouble with some bad surface; we had offered help and been refused, and with Evans alone his difficulties grew, whilst the wind sprang up and the snow started to drift. We had walked into the hut and found Meares, but now we all came out again. I sent for Lashly and Hooper and went back to help Day along. We had exasperating delays and false starts for an hour and then suddenly the machine tuned up, and off she went faster than one could walk, reaching Cape Armitage without further hitch. It was blizzing by this time; the snow flew by. We all went back to the hut; Meares and Demetri have been busy, the hut is tidy and comfortable and a splendid brick fireplace had just been built with a brand new stove-pipe leading from it directly upward through the roof. This is really a most creditable bit of work. Instead of the ramshackle temporary structures of last season we have now a solid permanent fireplace which should last for many a year. We spent a most comfortable night.
This morning we were away over the floe about 9 A.M. I was anxious to see how the motors started up and agreeably surprised to find that neither driver took more than 20 to 30 minutes to get his machine going, in spite of the difficulties of working a blow lamp in a keen cold wind.
Lashly got away very soon, made a short run of about 1/2 mile, and then after a short halt to cool, a long non-stop for quite 3 miles. The Barrier, five geographical miles from Cape Armitage, now looked very close, but Lashly had overdone matters a bit, run out of lubricant and got his engine too hot. The next run yielded a little over a mile, and he was forced to stop within a few hundred yards of the snow slope leading to the Barrier and wait for more lubricant, as well as for the heat balance in his engine to be restored.
This motor was going on second gear, and this gives a nice easy walking speed, 2 1/2 to 3 miles an hour; it would be a splendid rate of progress if it was not necessary to halt for cooling. This is the old motor which was used in Norway; the other machine has modified gears. 
Meanwhile Day had had the usual balancing trouble and had dropped to a speck, but towards the end of our second run it was evident he had overcome these and was coming along at a fine speed. One soon saw that the men beside the sledges were running. To make a long story short, he stopped to hand over lubricating oil, started at a gallop again, and dashed up the slope without a hitch on his top speed – the first man to run a motor on the Great Barrier! There was great cheering from all assembled, but the motor party was not wasting time on jubilation. On dashed the motor, and it and the running men beside it soon grew small in the distance. We went back to help Lashly, who had restarted his engine. If not so dashingly, on account of his slower speed, he also now took the slope without hitch and got a last handshake as he clattered forward. His engine was not working so well as the other, but I think mainly owing to the first overheating and a want of adjustment resulting therefrom.
Thus the motors left us, travelling on the best surface they have yet encountered – hard windswept snow without sastrugi – a surface which Meares reports to extend to Corner Camp at least.
Providing there is no serious accident, the engine troubles will gradually be got over; of that I feel pretty confident. Every day will see improvement as it has done to date, every day the men will get greater confidence with larger experience of the machines and the conditions. But it is not easy to foretell the extent of the result of older and earlier troubles with the rollers. The new rollers turned up by Day are already splitting, and one of Lashly’s chains is in a bad way; it may be possible to make temporary repairs good enough to cope with the improved surface, but it seems probable that Lashly’s car will not get very far.
It is already evident that had the rollers been metal cased and the runners metal covered, they would now be as good as new. I cannot think why we had not the sense to have this done. As things are I am satisfied we have the right men to deal with the difficulties of the situation.
The motor programme is not of vital importance to our plan and it is possible the machines will do little to help us, but already they have vindicated themselves. Even the seamen, who have remained very sceptical of them, have been profoundly impressed. Evans said, ‘Lord, sir, I reckon if them things can go on like that you wouldn’t want nothing else’ – but like everything else of a novel nature, it is the actual sight of them at work that is impressive, and nothing short of a hundred miles over the Barrier will carry conviction to outsiders.
Parting with the motors, we made haste back to Hut Point and had tea there. My feet had got very sore with the unaccustomed soft foot-gear and crinkly surface, but we decided to get back to Cape Evans. We came along in splendid weather, and after stopping for a cup of tea at Razor Back, reached the hut at 9 P.M., averaging 3 1/2 stat. miles an hour. During the day we walked 26 1/2 stat. miles, not a bad day’s work considering condition, but I’m afraid my feet are going to suffer for it.
