It was Paul himself who gave utterance to this exclamation. Apparently he had been holding his breath for half a minute past, in anticipation of what was to come; and this signified that the startling event was being put into play.

Elmer had shifted his tiller just enough to change the course of his boat, and veer slightly to leeward. Of course this necessitated a change in the running of the pursuing craft, otherwise the Lightning must immediately strike the stern of the leader.

Harry followed suit, and for a moment both boats continued on that slant. But it could not last, of course. The shore was too close by; and if they continued to veer to leeward both must go aground, to the utter demoralization of the delicate craft.

Paul could see that leering face of Pud almost within reach of his hand. It seemed as though the bully might be asking what he was going to do about it; and giving him to understand that he might as well cut his halyards, and let his sail drop, because he and Elmer were grimly determined that no iceboat should ever sail past the Glider, come what might.

So Paul set his teeth hard, expecting a spill of some sort when the bow of his boat struck the stern of the other, while going at this amazing speed. Perhaps his face was white, which fact could hardly be wondered at under the circumstances. But there was no sign of fear there. Paul proved game when the test came, just as Harry had known would be the case.

A foot—why the distance between the two boats must be measured by inches now, so rapidly had it been cut down by the rush of the pursuing craft.

Just as Paul gave a gasp, expecting to feel the shock of the collision, and perhaps be tumbled headlong over the smooth ice, he felt Harry make a sudden move.

The skipper of the Lightning had waited until the very last second, and then swung the tiller around!

Instantly obeying the rudder, the able boat changed her course. She no longer headed to leeward, but swung in the other direction, aiming for the windward bank of the river.

“Oh! bully! bully! bully!” cried Paul, as the plan of his chum flashed across his mind; and at the same time he occupied himself in tugging at the sheet in order to shape the bellying sail to the new course of the rapidly-driven boat.
