Describe the river on the way to Staines.

From the text:

And all the river down to Staines is dotted with small craft and boats and tiny coracles—which last are growing out of favour now, and are used only by the poorer folk.  Over the rapids, where in after years trim Bell Weir lock will stand, they have been forced or dragged by their sturdy rowers, and now are crowding up as near as they dare come to the great covered barges, which lie in readiness to bear King John to where the fateful Charter waits his signing.
