Mavor. — Bay of Fundy and Gulf of Maine 335 



are published in "Tables of Hourly Direction and Velocity 

 of the Currents and Time of Slack Water in the Bay of 

 Fundy and its Approaches." These tables give the aver- 

 age velocity and direction during each hour of the tide. 

 If we imagine a drop of water at the depth, 3 fathoms, 

 for which Dr. Bell Dawson's tables are constructed, and 

 moving each hour with the velocity and in the direction 

 there stated, the path which it would take during one tide 

 is indicated in Figure 1, where the lines marked i, 2, etc., 

 to II and H. W. indicate the direction and the distance the 

 drop would go during each hour. At the end of the first 

 tide it would have moved from a to h. The same final result 

 would have been attained had the drop moved directly from a 

 to b along the line ah. Were there no general movement of the 

 water, and were only the oscillations of the tide at work, the 

 drop would have returned to its original position a. The Hne ah 

 therefore represents a general movement of the water, and its 

 direction and length represent to the scale of the diagram 

 what may be called a resultant velocity in nautical miles per 

 tide. The resultant velocities have been determined for 

 each of the stations in the table and placed upon the chart 

 (Fig. 2), where the arrows represent in direction and on the 

 scale of the chart the distance traveled by the drop of water 

 in two tides or approximately one day. 



From the chart (Fig. 2) it is seen that there is a general 

 movement of the water around the southwestern end of Nova 

 Scotia and into the Bay of Fundy on the Nova Scotia side. 

 This is seen in the direction of the resultant velocities at 

 stations R, N, M, J, H, K, G, F and C. At stations S, Q, 

 P and L the resultant velocities are not in this direction, but 

 towards the shore. This may be due to these stations being in 

 eddies of the general current caused by the shoals which are 

 near them. Within the bay a general movement of the water 

 across it from the Nova Scotia to the New Brunswick side 

 is shown at stations B and A. At station E to the southeast 

 , of Grand Manan the general movement is out of the bay.
