AFTER HIGH-WATER AT CHERBOURG. 



As we see, the water is flowing in some parts while it 

 is receding in others. In this regard it is interesting to 

 study the Bays of Granville and Calvados, which are sepa- 

 rated by Cotentin. The diagram (Fig. 2), which I have 

 constructed according to data presented by M. Hdouin, 

 shows that the Atlantic flux fills Granville Bay and that 

 the latter overflows into Calvados Bay, which in turn 

 empties itself into the former. The chief effort of the 

 Atlantic is brought to bear upon Granville Bay, which is 

 never at rest. It is traversed by powerful currents with 

 an average flow of 2*6 knots, which through the Hague 

 channel increases to 9 knots. Calvados Bay, on the 

 other hand, is calmer ; the average pace of its currents
