Roberts turned upon him again quite fiercely.

“He seemed to have turned acid right through, and snapped and snarled at those about him; and then—”

“Now, look here, young fellow,” cried Roberts, interrupting his companion, “I’m not all a fool, Frank Murray, and I can see quite plainly enough that this is all meant for a go at me. Do you mean to tell me that I have turned upon every one to snap and snarl at them? Because if you do, say so like a man.”

“Well, old chap—” began Murray, smiling.

“Oh, you do, do you? You’ve made up your mind to quarrel with me, have you? Very well, sir. I don’t want to be on good terms with a fellow who, in spite of the way in which I have made myself his friend ever since he joined, is determined to—determined to—Here, this is beyond bearing, sir. We’re too big now to settle our quarrels, like a couple of schoolboys, with our fists, but the wretched state in which we are compelled to exist by the captain’s absurd prejudices against settling a dispute in a gentlemanly way compels one to put off all consideration of age and position; so come down below. We can easily get to where the men will take care that we are not interrupted by the officers; and if I don’t give you the biggest thrashing you ever had, it’s because I am weak from the effects of that accident and being dragged under water for so long. Now then, come on, and—don’t irritate me any more by grinning in that absurd way, or I shall strike you before you put up your hands on guard, and then—”

The lad, who was gazing wildly at his companion, stopped short, for, half startled now by his brother middy’s manner, Murray had laid his hand upon his arm.

“Steady, Dick,” he said quietly. “You’re not yourself, old chap. I didn’t mean to irritate you. Don’t go on like that; here’s the doctor coming forward, and I don’t want him to come and see you now.”

These words wrought a complete change, for to Murray’s surprise the agitated lad slipped his wrist free, and brought his hand down firmly upon that of his companion, to close it in a firm grip.

“Here, Frank,” he whispered, “don’t take any notice of what I said. I couldn’t help it. I don’t know what has come to me. I must be like the fellow you were talking about, and if the doctor knows, I feel—I’m sure that I shall be much worse.”

“Hist! Keep quiet. Let’s be looking at the fish. Look at that.”
