twenty-five miles. These measurements refer to spring tides, 
which are highest. But the belief which so generally prevails, 
that the tide assumes, as it rushes onward with loud roar and 
great velocity, a high, almost vertical wave, or “ bore,’ as itis 
termed, which even draws into its vortex such animals as may 
stray near the beach, is wholly erroneous. There is no bore or tidal 
wave on the Bay of Fundy. Navigation there is neither danger 
ous nor difficult, unless it be from fog or ice. In the absence : 
storms, the tides, ebb and flood, are accompanied by scarcely a 
ripple. Even at Cape Split, where the bay suddenly contracts to 
a width of about three and a-half miles, the “ wave” wll not meas- 
ure one inch in height. What can have been the origin of this — 
fable, which has not only obtained general credence among many, 
but is even accepted by men of science without question, and is 
yet chimerical as a madman’s dream? Probably the very trifling 
bore which does really exist on two small tributaries of the bay, 
the Petitcodiac and Shubenacadie. The bore on the former river 
I measured at Moncton, N. B., eighty-nine miles E.N.E. of St 
John, and found it just three and a-half feet high, with a travel 
up-stream of six miles per hour. It is caused by the last of the 
ebb tides being met and repelled by the flood tide in a narrow 
stream confined by almost vertical banks——P. F. MeCourt, M.D,
