"Tak' to yer oar, Curly." Along this part of the bank, some twenty feet above them, ran a mill-race, which a few yards lower down communicated by means of a sluice with the river.

This sluice was now open, for, from the late rains, there was too much water; and the surplus rushed from the race into the Glamour in a foaming cataract.

Annie seeing that the boys were uneasy, got very frightened, and, closing her eyes, sat motionless.
Louder and louder grew the tumult of the waters, till their sound seemed to fall in a solid thunder on her brain.

The boys tried hard to row against the stream, but without avail.

Slowly and surely it carried them down into the very heart of the boiling fall; for on this side alone was the channel deep enough for the boat, and the banks were too steep and bare to afford any hold.
