Basil Field: In the happy days of old, when fish were foolish, and fishermen were few, one, two, three, or more flies were fastened at intervals on a line; a cast was made across the stream, the rod-point was depressed, and the flies allowed to sink as they drifted down the current. When the line became fully extended, the flies began to rise to the surface, and to sweep round in a curve towards the bank on which the angler stood, the fly nearest him, called the “bob-fly,” tripping and dancing as it skimmed the water.
