The river a splendid stream rushing rapidly N. ward over a bouldery bottom. The banks high and steep (try to do some fishing at river breek?). The water transparent & blue Fine trout in the stream of which some caught by the men. Current so swift that though water only up to horses belly some nearly carried away.
