They had decided to row to the southern end of the lake and engage a team to meet them the following week and to carry them to Glenn's Falls, where they intended to ship the boat on board a canal-boat bound for New York, and to return home by rail. To avoid the heat of the sun, they started down the lake immediately after breakfast, and forgot to put out the fire before they left the island.

Harry looked back, and saw that the cloud of smoke was rapidly increasing.
"It's not the fire that's making all that smoke!" he exclaimed.
