The Chancellor tacks to stern, and glides back into the basin, which is once more her prison.

"Well, captain," says the boatswain, "what's to be done now?"

"I don't know," said Curtis, "but we shall get across somehow."

CHAPTER XXI

THE "CHANCELLOR" RELEASED FROM HER PRISON

NOVEMBER 21 TO 24.—There was assuredly no time to be lost before we ought to leave Ham Rock reef. The barometer had been falling ever since the morning, the sea was getting rougher, and there was every symptom that the weather, hitherto so favorable, was on the point of breaking; and in the event of a gale the Chancellor must inevitably be dashed to pieces on the rocks.

In the evening, when the tide was quite low, and the rocks uncovered, Curtis, the boatswain, and Dowlas went to examine the ridge which had proved so serious an obstruction. Falsten and I accompanied them. We came to the conclusion that the only way of effecting a passage was by cutting away the rocks with pikes over a surface measuring ten feet by six. An extra depth of nine or ten inches would give a sufficient gauge, and the channel might be accurately marked out by buoys; in this way it was conjectured the ship might be got over the ridge and so reach the deep water beyond.

"But this basalt is as hard as granite," said the boatswain; "besides, we can only get at it at low water, and consequently could only work at it for two hours out of the twenty-four."

"All the more reason why we should begin at once, boatswain," said
Curtis.

"But if it is to take us a month, captain, perhaps by that time the ship may be knocked to atoms. Couldn't we manage to blow up the rock? we have got some powder aboard."
