128. — Further Data Upon the Rate of Recession of the 
Coast Line of New Brunswick. 
Read in Abstract June 10, 1913. 
In Note No. 119 of this series, I gave the results of 
measurements made to determine the rate of recession of 
a piece of coast line on our North Shore. While the Note 
was in press it occurred to me that additional, and probably 
(because involving a longer period, of time) more exact, data 
might be yielded by a re-survey of two places which I had 
mapped fifteen years ago; and accordingly I visited those 
places in the summer of 1912, with results which follow. 
The first of the places was old Fort Monckton at Baie 
Verte, the ruins of which have long been in process of erosion 
by the sea. My map of the Fort, showing the position 
of the encroaching shore line, was made in 1897, and was 
published in the Transactions of the Royal Society of Canada , 
V, 1899, ii, 290. On my visit in 1912, however, I found that 
while a considerable part of the point in front of the Fort, 
composed of loose drift, has been washed away, there has 
been no measurable change in the condition of the ramparts 
of the Fort. The explanation thereof is, however, fairly 
apparent, for the actual works of the Fort here rest upon 
sandstone ledges which rise above the highest tides, so that the 
loose soil can only be removed for the future in proportion 
as the ledges are first eroded away; and this, of course, will 
proceed but slowly. Furthermore, the erosion of the point, 
and also of the northeast corner of the rampart, has been 
By W. F. Ganong.
