Note return — COMMERCIAL POLICY.

The river Chagre, which falls into the Atlantic, is the nearest transitable point to Panama, but unfortunately the harbour does not admit vessels drawing more than twelve feet water.22 There the traveller embarks in a bonjo, (a flat-bottomed boat,) or in a canoe, made of the trunk of a cedar-tree, grown on the banks to an enormous size. The velocity of the downward current is equal to three miles an hour, and greater towards the source. The ascent is consequently tedious; often the rowers are compelled to pole the boat along, a task, under a burning sun, which could only be performed by negroes. In the upper part of the stream the navigation is obstructed by shallows, so much so as to render the operation of unloading unavoidable. Large trunks of trees, washed down by the rains, and sometimes embedded in the sands, also occasionally choke up the channel, impediments which preclude the possibility of a steam power being used beyond a certain distance up. No boat can ascend higher than Cruces, a village in a direct line not more than twenty-two miles from Chagre harbour; but owing to the sinuosities of the river, the distance to be performed along it is nearly double. To stem the current requires from three to eight days, according to the season, whereas the descent does not take more than from eight to twelve hours.
