CROCODILES, HIPPOPOTAMUSES, AND LEAKY PONTOONS MAKE AN ADVENTURE OF FLOATING TRUCKS OVER JUNGLE RIVERS When canoes in the French Cameroons were large enough, a raft built upon them would support one of the expedition's trucks fully loaded. Atthis crossing only a small raft could be built and cases and boxes had to be transported separately. Often the craft ran aground, necessitating much labor togetitoff.When streams were shallow the rafts were poled; when deep, they were paddled by natives to the accompaniment of drums beating lustily (page 342). Mr. Thaw supervised the work, at the same time keeping a weather eye for "hippos" and "crocs," residents of these streams.
