The river was compressed to seventy-five feet in one place on this day.

On the 10th they made about five miles, and met with a serious accident: two of the boats were carried back over a rapid, but were luckily secured again without having suffered damage.

The declivity was now very great, and the stream flowed along between solid granite, where footing was both difficult and dangerous, and pulling the boats up over the rocks taxed the combined strength of the crews.

Everything had to be unloaded at one bad place and the first boat was nearly swamped.

All could not be taken up before dark, so a "dreary camp is made among the debris of the slopes, where, cuddled up Indian-fashion, the weary hours of the night are passed." The labour was tremendous, and two of the party became ill: one, a Mohave, who was badly bruised by being thrown upon the rocks.
