Cyrus Harding and Neb were taken into confidence, and the sailor suspected nothing during the whole time, necessarily somewhat long, which was required in order to dry the small leaves, chop them up, and subject them to a certain torrefaction on hot stones. This took two months; but all these manipulations were successfully carried on unknown to Pencroft, for, occupied with the construction of his boat, he only returned to Granite House at the hour of rest. For some days they had observed an enormous animal two or three miles out in the open sea swimming around Lincoln Island. This was a whale of the largest size, which apparently belonged to the southern species, called the "Cape Whale." "What a lucky chance it would be if we could capture it!" cried the sailor. "Ah, if we only had a proper boat and a good harpoon, I would say, 'After the beast,' for he would be well worth the trouble of catching!" "Well, Pencroft," observed Harding, "I should much like to watch you handling a harpoon. It would be very interesting." "I am astonished," said the reporter, "to see a whale in this comparatively high latitude." "Why so, Mr. Spilett?" replied Herbert. "We are exactly in that part of the Pacific which English and American whalemen call the whale field, and it is here, between New Zealand and South America, that the whales of the southern hemisphere are met with in the greatest numbers." And Pencroft returned to his work, not without uttering a sigh of regret, for every sailor is a born fisherman, and if the pleasure of fishing is in exact proportion to the size of the animal, one can judge how a whaler feels in sight of a whale. And if this had only been for pleasure! But they could not help feeling how valuable such a prize would have been to the colony, for the oil, the fat, and the bones would have been put to many uses. Now it happened that this whale appeared to have no wish to leave the waters of the island. Therefore, whether from the windows of Granite House, or from Prospect Heights, Herbert and Gideon Spilett, when they were not hunting, or Neb unless presiding over his fires, never left the telescope, but watched all the animal's movements. The cetacean, having entered far into Union Bay, made rapid furrows across it from Mandible Cape to Claw Cape, propelled by its enormously powerful flukes, on which it supported itself, and making its way through the water at the rate little short of twelve knots an hour. Sometimes also it approached so near to the island that it could be clearly distinguished. It was the southern whale, which is completely black, the head being more depressed than that of the northern whale.
