an original element in the legend is the woodmen 's bringing of niniel to a place ( 'silver bowl ' ) where there was a great waterfall ( afterwards dimrost , the rainy stair , where the stream of celebros 'fell towards teiglin ' ) : and these falls were near to the dwellings of the woodmen -- but the place where they found niniel was much further off in the forest ( several days ' journey ) than were the crossings of teiglin from dimrost .
