If we extend these observations further south we will find 
that the times of the spring tides F. and C., from Chesapeake 
Bay to Sandy Hook occur from 7.51 to 7.21 local time, and that 
they rise from 3} at the former to 5} feet at the latter place. 
From the western extremity of Long Island to Bridgeport the 
shore trends easterly, and the tidal wave courses along as well as 
upon it. The times are 10.12 and 11.11 respectively. Springs 
rise, 9 to 8 feet; neaps, 7? to 6} between these points. 
Within the Gulf, as will be seen above, from Plymouth Har- 
bour to Mount Desert it is high water flood tides about the same 
time. Springs rise from 10 to 11 feet; neaps about 9 feet. We 
may place this, the American side, as having, say, an abnormal 
height of from four to five feet. On the other horn of the cres- 
cent, from Cape Sable to Chebogue, the times are from 8.30 to 
10.04. Springs rise from 8 to 15 feet; neaps, 62 to 117, so that 
we have the abnormal height of tides of 7 to 8 feet on this, the 
Nova Scotia side, piled up before we enter the Bay of Fundy 
proper; and here we have the fountain, the beginning, of the Bay 
of Fundy tidal phenomena. 
The problem which is suggested by these observations is 
not so complicated as it may at first seem to be, since a compari- 
son of the effect is so accessible to observation, The great tidal
