I had been making some tidal observations on an upright, fixed in a comparatively quiet spot on the east coast, and it was here that I contemplated erecting the gauge. Two snow-gauges, eight inches each in diameter, were amongst the meteorological equipment and it appeared that if these two were soldered together a suitable pipe could be made. Further, the pipe was to be protected from the violence of the seas by planks fixed round it. Sandell agreed with the idea and forthwith set about soldering the two together and making a suitable float, the one supplied being too wide. All that now remained was to erect the gauge.
The two following afternoons were devoted to stowing the new stores. We carried everything across and stacked them at the south-west end of the Shack. Unfortunately, the boots which we had ordered did not come, but Captain Davis let us have five pairs of light bluchers out of the ship's stores, and we reckoned that these with extra soles and a few hobnails would hold out till August or September, when a sealing vessel was expected.
The 'Aurora' returned from the south of the island on the 19th and reported having had a rough experience in the north-east to south gale which blew on the two previous days. The wind came out of the north-east very suddenly on the 17th, and some very strong squalls were experienced. A calm prevailed for several hours in the evening, but a south-east gale then sprang up and blew all day on the 18th, gradually working into the south and dying away during the night.
Early on the 20th the 'Aurora' steamed out of the bay, bound north as we thought, but she returned again in the evening, and we signalled to know if anything were wrong. They replied, "All well, but weather very bad outside." She lay at anchor in the bay all next day as it was snowing and blowing very hard from the south-west, but at 8.45 A.M. on the 22nd she disappeared in the north and we did not see her again for some months. A few hours after her departure the wind increased in force, and a continuous gale raged for the next five days.
Sandell and I now made a start at erecting the tide-gauge, and after the lapse of five days got the instrument into position. We could work on it only at low tide, for much rock had to be chipped away and numerous wire stays fixed. The work was therefore of a disagreeable character. Its appearance when finished did not by any means suggest the amount of trouble we experienced in setting it up, but the fact that it stood the heavy seas for the following eighteen months without suffering material damage was a sufficient guarantee that the work had been well done.
A tremendous sea was running on the 25th as a result of the previous two days' "blow" and a heavy gale still persisting. Spray was scudding across the isthmus, and the sea for a mile from the shore was just a seething cauldron. The wind moderated somewhat on the 26th, but strong squalls were experienced at intervals throughout the day, and on the 27th a strong wind from the south-west brought rather heavy snow.
On the following day a westerly gale sprang up which shifted suddenly to south-south-west and south-west in the evening and was accompanied by fierce hail and snow-squalls throughout the night. Without moderating to any extent the gale continued to blow on the 29th and passed through west to west-north-west, finally lasting till the end of the month.
Something in the nature of a "tidal" wave occurred during the night of the 28th, for, on rising the following morning, I was considerably astonished to see that the sea-water had been almost across the isthmus. To effect this, a rise of twenty or twenty-five feet above mean sea-level must have taken place and such a rise appeared abnormally high. Our coal heap, which we had hitherto regarded as perfectly safe from the sea, was submerged, as shown by the kelp and sand lying on top of it, and the fact that seven or eight briquettes were found fifteen feet away from the heap.
Nothing at the wireless station was damaged and work went on as usual. The wind used to make a terrific noise in the aerial wires, but this did not affect the transmission of messages. The howling of the wind round the operating-hut interfered with the receiving, at times making it extremely difficult to hear signals; particularly on nights not favourable for wireless work.
Hamilton was at this time concentrating his attention on shags or cormorants. This species of cormorant is peculiar to the island, being found nowhere else. They are blue-black, with a white breast, and on the head they have a small black crest. At the top of the beak are golden lobes, while the skin immediately round the eye is pale blue. They remain on the shores of the island all the year and nest on the rocks in or very close to the water. They form rookeries and build nests of grass, laying three eggs about the end of November. The period of incubation is six weeks. They live entirely on fish, and, on that account, neither the birds nor the eggs are palatable. They are very stupid, staring curiously till one gets almost within reach of them, when they flap heavily into the water. They are easily caught when sitting on the nest, but a shag rookery, like most other rookeries, is by no means a pleasant place in which to linger.
