Dory did not tell his companions what he had been thinking about; but he hoped to leave the Missisquoi at this point, or to get a better start of her. He preferred to explain his plan after he had carried it out if it were a success, or to keep silent if it were a failure. He watched the Missisquoi very closely, for his own movements would depend upon hers. There was plenty of water to the northward of the island, but there was a shoal to the southward.
If the captain of the steamer had been wise, if he had had his eyes open, he would have kept to the eastward; but he followed directly in the wake of the Goldwing, and was within less than a quarter of a mile of her.
"Do you know how much water the Missisquoi draws, Thad?" asked Dory, as the Goldwing came up with the island.
"I heard Captain Vesey say that she drew six feet when she had her coal in," replied Thad.
"I heard him say so when we were off Apple-Tree Shoal," added Corny. "I asked him why he didn't go close up to the buoy; and he said there was not more than six feet of water on the shoal, and the boat might touch bottom."
"I thought she didn't draw over five feet. If she draws six, so much the better," added Dory.
"Why is it so much the better, Dory?" asked Thad.
"Hold on all, and don't ask any more questions!" said Dory, laughing. "I have business on my hands just now, and I will tell you all about it in about ten minutes."
The skipper had gybed the boat under the lee of Valcour's; but the wind was too fresh where he was now to repeat the manœuvre. It was a gale in this part of the lake, and the Goldwing worked very lively.
"Corny, I want you to handle that jib-sheet," said he when he was ready for his next move.
