In Fig. 6 the centreof the line, the current in midstreambeing swifter, would have a constantlyincreasing downward curve, while inFig. 7 the curve would be the positions of line and fly wouldbe moving constantly diagrams have been drawn in thissimple form to prevent the confusionthat might result from complicateddrawings attempting to show the al-ways changing curves in the line.
