The end of the year 1868 found them occupied by these important labours, to the exclusion of almost all others. At the expiration of two months and a half the ribs had been set up and the first planks adjusted. It was already evident that the plans made by Cyrus Harding were admirable, and that the vessel would behave well at sea.
Pencroft brought to the task a devouring energy, and scrupled not to grumble when one or the other abandoned the carpenter’s axe for the gun of the hunter. It was nevertheless necessary to keep up the stores of Granite House, in view of the approaching winter. But this did not satisfy Pencroft. The brave honest sailor was not content when the workmen were not at the dockyard. When this happened he grumbled vigorously, and, by way of venting his feelings, did the work of six men.
The weather was very unfavourable during the whole of the summer season. For some days the heat was overpowering, and the atmosphere, saturated with electricity, was only cleared by violent storms. It was rarely that the distant growling of the thunder could not be heard, like a low but incessant murmur, such as is produced in the equatorial regions of the globe.
The 1st of January, 1869, was signalised by a storm of extreme violence, and the thunder burst several times over the island. Large trees were struck by the electric fluid and shattered, and among others one of those gigantic micocouliers which shaded the poultry-yard at the southern extremity of the lake. Had this meteor any relation to the phenomena going on in the bowels of the earth? Was there any connection between the commotion of the atmosphere and that of the interior of the earth? Cyrus Harding was inclined to think that such was the case, for the development of these storms was attended by the renewal of volcanic symptoms.
It was on the 3rd of January that Herbert, having ascended at daybreak to the plateau of Prospect Heights to harness one of the onagas, perceived an enormous hat-shaped cloud rolling from the summit of the volcano.
Herbert immediately apprised the colonists, who at once joined him in watching the summit of Mount Franklin.
“Ah!” exclaimed Pencroft, “those are not vapours this time! It seems to me that the giant is not content with breathing; he must smoke!”
This figure of speech employed by the sailor exactly expressed the changes going on at the mouth of the volcano. Already for three months had the crater emitted vapours more or less dense, but which were as yet produced only by an internal ebullition of mineral substances. But now the vapours were replaced by a thick smoke, rising in the form of a greyish column, more than three hundred feet in width at its base, and which spread like an immense mushroom to a height of from seven to eight hundred feet above the summit of the mountain.
“The fire is in the chimney,” observed Gideon Spilett.
“And we can’t put it out!” replied Herbert.
