All Aboard by Oliver Optic

The boys all had remarkably good appetites, and therefore dinner was no unimportant event in the experience of the day. Somehow, boys contrive to be hungry at almost all times of the day, even without the stimulus of pulling three hours at an oar. There was something, too, in the circumstance of dining in a beautiful grove, on the bank of the river, with their boats floating near them, which rendered the occasion peculiarly pleasant -- which made their cold meat, doughnuts, and apple pie taste much better than usual.

But the adventure was not yet completed. The head waters of navigation had not been reached, and their love of exploring did not permit them to spend any unnecessary time over the meal. Tony and his oarsmen had reported themselves at the grove, and after "bolting" their dinner, had resumed their occupation; and the boys perceived the Dip half a mile up the river before they were ready to start.
