The third and last boat was the _Canonita_, which E.O.Beaman, the photographer steered, while Andrew Hattan, rowed aft, and Clement Powell, assistant photographer, forward.

This order was preserved, with a few exceptions, throughout the first season's work.

It was the duty of Prof.and Jones to make a traverse (or meander) of the river as we descended.

They were to sight ahead at each bend with prismatic compasses and make estimates of the length of each sight, height of walls, width of stream, etc., and Cap was to put the results on paper.
The Major on his first boat, kept a general lookout and gave commands according to circumstances.

He remembered the general character of the river from his former descent, but he had to be on the _qui-vive_ as to details.
