THE TIDES OF THE BAY OF FUNDY—MURPHY. 59 
Chiegnecto, a distance of nearly 100 miles, within five hours; this 
could not be done from the currents alone. It is the translating 
movement that effects such performance. It is not an influx 
altogether, that fills up the Bay during that time—it is largely 
due to the piling up of the littoral waters within it. The cur- 
rents seldom exceed ten miles per hour. The tidal wave, if 
unimpeded, or unobstructed by coasts, would travel round the 
earth in a lunar day of 24 hours. It is this wave that floods 
the Bay of Fundy (No. 1) as well as every other tidal bay, 
bight and recess on our planet. 
It has been already said that the wave of translation affects 
the depths as well as the surface. Here there is very convincing 
proofs of this. Chiegnecto Bay, Minas Basin and Cobequid Bay 
are divergent arms, extending northerly and easterly from the 
head of the Bay of Fundy. The ebb tide nearly empties them, 
leaving here and there muddy pools and shallow channels. A 
regular flood tide refills them to a depth of from forty to fifty 
feet, whilst the mean level between these extremes is just the 
same as the mean level of the Atlantic Ocean along our shores, 
where the extremes of tide do not exceed eight feet, and nearly the 
same as the mean of Northumberland Straits, where they seldom 
exceed six feet. 
But we are afforded an opportunity of giving a thorough 
practical application to this part of our theory. Referring to 
the report of the Chief Engineer of Public Works on Baie Verte 
Canal, Ottawa, 1874, Mr. Page says: “It may at once be stated, that 
“a daily record of the rise and fall of tides in Cumberland Basin, 
“was kept from the 13th August to the last day of December, 
“1870; and during that time there were between the 13th and 
“31st of August, four days ; in September two days; in October 
“three days ; in November one day ; and none in December that 
“the tides did not rise to 86 feet. Between the 13th and 31st 
“of August there were ten days; in September fourteen days ; 
“in October sixteen days; in November twenty days; and in 
“December twenty-two days, that the tides did not rise to over 
“881 feet. 
“ Between the 13th and 31st of August, there were fifteen
