Ch 16..............

From the text:

The run would have been more delightful still, if it had not been for a lot of wretched small boats that were continually getting in the way of our launch, and, to avoid running down which, we had to be continually easing and stopping. It is really most annoying, the manner in which these rowing boats get in the way of one’s launch up the river; something ought to done to stop it.
