Asbury
tells how "the water kept the carriage up."
It floated like a boat. Across deep creeks the horses were obliged to swim
"among rocks, holes, and logs."
Even when not swept away by floods, wooden bridges - two long poles with short
logs laid across like railway sleepers - entangled a horse's legs. Asbury writes
of crossing in a boat once "with the horses's hind legs over the
side!"
Next time he laid straw on the deck so that they did not slip.
