We went down on the boat to the noon camp, and as soon as we had refreshed the inner man we proceeded thinking it about time for rapids to appear.

We had not gone far before we distinguished a familiar roar just preceding the turn of a bend which disclosed three lying within half a mile.

They were not bad but the river was wide and shallow, making the descent more difficult than it would ordinarily have been.

The river was now approaching its lowest stage, and we saw an uncomfortable looking lot of rocks.

High water makes easy going but increases the risk of disaster; low water makes hard work, batters the boats, and delays progress, but as a rule it is less risky.
