In a couple of hour my men had built a little sleeping-shed for me, about eight feet by four, with a bench of split poles, they themselves occupying two or three smaller ones, which had been put up by former passengers.
The river here was about twenty yards wide, running over a pebbly and sometimes a rocky bed, and bordered by steep hills with occasionally flat swampy spots between their base and the stream.

The whole country was one dense, Unbroken, and very damp and gloomy virgin forest.

Just at our resting-place there was a little bush-covered island in the middle of the channel, so that the opening in the forest made by the river was wider than usual, and allowed a few gleams of sunshine to penetrate.
Here there were several handsome butterflies flying about, the finest of which, however, escaped me, and I never saw it again during my stay.

In the two days and a half which we remained here, I wandered almost all day up and down the stream, searching after butterflies, of which I got, in all, fifty or sixty specimens, with several species quite new to me.

There were many others which I saw only once, and did not capture, causing me to regret that there was no village in these interior valleys where I could stay a month.
