“Something is wrong,” answered Guert, coolly, but very decidedly; “and it is something that must be seen to.”

As this was said, Guert stepped out on the ice, which he struck a hard blow with the heel of his boot, as if to make certain of its solidity. A second report was heard, and it evidently came from behind us. Guert gazed intently down the river; then he laid his head close to the surface of the ice, and looked again. At the same time, three or four more of these startling reports followed each other in quick succession. Guert instantly rose to his feet.

“I understand it, now,” he said, “and find I have been rather too confident. The ice, however, is safe and strong, and we have nothing to fear from its weakness. Perhaps it would be better to quit the river notwithstanding, though I am far from certain the better course will not be to push on.”

“Let us know the danger at once, Mr. Ten Eyck,” said Herman Mordaunt, “that we may decide for the best.”

“Why, sir, I am afraid that the rains and the thaw together, have thrown so much water into the river, all at once, as it might be, as to have raised the ice and broken it loose, in spots, from the shores. When this happens above, before the ice has disappeared below, it sometimes causes dams to form, which heap up such a weight as to break the whole plain of ice far below it, and thus throw cakes over cakes until walls twenty or thirty feet high are formed. This has not happened yet, therefore there is no immediate danger; but by bending your heads low, you can see that such a break has just taken place about half a mile below us.”

We did as Guert directed, and saw that a mound had arisen across the river nearer than the distance named by our companion, completely cutting off retreat by the way we had come. The bank on the west side of the Hudson was high at the point where we were, and looking intensely at it, I saw by the manner in which the trees disappeared, the more distant behind those that were nearer, that we were actually in motion! An involuntary exclamation caused the whole party to comprehend this startling fact at the same instant. We were certainly in motion, though very slowly, on the ice of that swollen river, in the quiet and solitude of a night in which the moon rather aided in making danger apparent than in assisting us to avoid it! What was to be done? It was necessary to decide, and that promptly and intelligently.

We waited for Herman Mordaunt to advise us, but he referred the matter at once to Guert's greater experience.

“We cannot land here,” answered the young man, “so long as the ice is in motion, and I think it better to push on. Every foot will bring us so much nearer to Albany, and we shall get among the islands a mile or two higher, where the chances of landing will be greatly increased. Besides, I have often crossed the river on a cake, for they frequently stop, and I have known even loaded sleighs profit by them to get over the river. As yet there is nothing very alarming;—let us push on, and get nearer to the islands.”

This, then, was done, though there was no longer heard the laugh or the song among us. I could see that Herman Mordaunt was uneasy about Anneke, though he could not bring her into his own sleigh, leaving Mary Wallace alone; neither could he abandon his respectable connection, Mrs. Bogart. Before we re-entered the sleighs, I took an occasion to assure him that Anneke should be my especial care.

“God bless you, Corny, my dear boy,” Herman Mordaunt answered, squeezing my hand with fervour. “God bless you, and enable you to protect her. I was about to ask you to change seats with me; but, on the whole, I think my child will be safer with you than she could be with me. We will await God's pleasure as accident has placed us.”
