for road building ; indeed it was not known what it was until Jan-

THE BEACH PHENOMENA AT QUACO, N. B. 
By Charles Livy Whittle, Cambridge, Mass. 
The abnormally high tides of the bay of Fundy have permitted 
the existence of a beach line, or bar across the harbor of Quaco, 
a parallel of which does not occur at airy point on the Atlantic 
coast south of the seaward end of the bay. Similar bars now con- 
nect the former islands of Marblehead and Nahant off the coast o 
Massachusetts. These, like bars in general, have their concavity 
opening towards the fetch of the waves, and at no time are they 
submerged unless it be during the progress of a severe storm 
which may temporarily destroy them, wholly or in part, by beach- 
ing. They are usually capped by a ridge of large-sized pebbles 
forming the storm beach. 
The harbor of the village of Quaco, which is an arm of the bay 
of Fundy, in extent is some three miles north and south, and two 
miles deep. This beautiful water area is bordered by steep cliffs
