'FranklyD, Mayor Of Vancouver, July 81, to Lord
Mayor of Gondon:-The infant colony, Vancouver,
5000 miles distant, sends telegraphic cordial greet
ings to mother England"
Il To this the Lord Mayor of London, taking up
the vein, and reciprocating the sentiments Of
his lar distant correspondent, replied as fol
lows:-
"To the Mayor of Vsncouyer's Island Mother
England ACKNOWLEDGES the cordial greeting of her
IN ant son, Vancouver May peace, goodwill, and
unanimty unite ah0 prosper our happy family" u
1t will be observed that three days were
occupied in the transmission OF the message
between Vancouvers Island and this country.
It would be carried across the Continent OF
America to oNewtoundland-how W tar by telegraph
does not appear. Seven hours, or thereabouts,
would be spent in conveying ii by steamer from
the American coast to Newfoundland, a distance
of 10 miles; from twelve TO fourteen hours
thence by the Atlantic Gable 10 Valenta, and
thence 10 London about an hour more, making
three days and nights, or 72 hours. Altogether
at the late of upwards OF Ill miles an hour, but
in the 40 miles from the American shore to
Newfoundland it could only be conveyed at the
rate of 10 miles an hour. .a rH .f

1t IS to be regretted that the Newfoundland line
