“Not much, I believe. I came down on you, and you formed a soft cushion,” answered the stout gentleman, good-naturedly. “But as to helping me up, do not, I pray you, attempt it on any account; we shall both of us go in if you do. Let us both roll away in opposite directions from the crack before we attempt to get on our feet. See how I manage.”

As the stout gentleman spoke, he began slowly to roll himself over and over away from the centre of the star, and Frank imitating him, they were both of them soon again on their legs. Frank was going off again at full speed, having once more repeated his apologies for his carelessness, when the stout gentleman stopped him.

“We must not leave others to fall into the danger from which we have escaped,” he cried out. “I observed, just now, some triangles with labels on the top, marked cracked and dangerous. We will get one and place it over the spot.”

“I’ll go and get the sign-posts you speak of,” said Frank. “Don’t trouble yourself, sir.”

“Then I will keep guard round the spot, to prevent any unwary person from approaching it,” said the stout gentleman.

Frank, on his return, found him going round and round the star.

“By to-morrow, I daresay, the wound will have healed,” he remarked. “By pressing it gradually down, as I have been doing, the water will have risen into the interstices and have frozen the broken pieces together.”

“I hope, sir, that I shall not be so clumsy again. I may not always meet people ready to take a knock-down so good-naturedly as you have done,” said the midshipman.

Frank and the stout gentleman became great friends after this, and Frank obtained from him many useful hints about skating. Meantime, several other people assembled on the lake, which now presented a very animated spectacle. Frank having come back to see how Ellis was getting on, found Ernest with him, giving him some further instruction, from which the pupil was much benefiting.

“Well, Ernest,” said Frank, “we have not had a skate together for a long time. What do you say to a race round the pond? I have got the use of my legs, I find, pretty well, but I don’t think I could come any of those twists and turns, and spread-eagle kind of things.”
