"Better not try too hard," came the cautious answer, "the weight of the line that is out is a heavy pull on him. Unless he's a monster he'll have to stop soon."

Fifty feet more of line ran out before the rush stopped, and then a change of action at the other end of the line telegraphed the message to the boy's fingers that the tuna, for the first time in its life, had felt fatigue. From over four hundred feet away Colin felt the call and realized that now he might expect a victory if only he could keep up the fight to the end and never make a slip. One error, he knew, would be fatal; one jerk, and the line would snap, one strain too great, and the strands would give way.

He began to reel in. His back ached and his fingers became cramped, but still he reeled, every

fifty feet or so having to let the line run out as the tuna made a rush, so that a quarter of an hour's careful bringing in would be spoiled in thirty seconds. In forty minutes of heartbreaking strain, the boy had gained not more than forty feet of line, but he was game and stuck to it manfully. Reeling in carefully, the fish either sulking or resting, in the next few minutes he won his greatest gain and pulled in until there was not more than one hundred feet of line out. His heart was beating high with hope, when the tuna sighted the boat again and darted away, apparently as fresh and full of fight as when he had at first been hooked.

At this last rush, when it appeared that there was no immediate slackening of the powers of the splendid fish, Major Dare said:

"Do you want me to finish him for you?"

In his inmost heart Colin feared that he would have to give up, but he did not want to admit it. He was utterly inexperienced in the sport and knew nothing of the many ways whereby older anglers relieve themselves of much of the strain, but the boy's nerve was untouched, and he set his teeth and answered:

"I want to bring him in all by myself, if I can, Father. I'm not done yet, not by a long shot.

But if you think I ought to let you finish it, why, I suppose I'll have to."

"No, I want to see you bring him in," his father said; "only don't kill yourself at it. It's just as well not to overstrain yourself; it's easy to have too much energy without judgment."
