2. Ona modern Submerged Forest at Fort Lawrence, Nova Scotia ; 
by J. W. Dawson, Esq., F.G.S., (Quart. Journ. Geol. Soc., vol. xi, p. 
119.)—The extraordinary tides of the Bay of Fundy, and its wide 
marshes and mud-flats, are well known to geologists as affording some 
of the best modern instances of rapid tidal deposition, and of the pre- 
servation of impressions of footsteps, rain-drops and sun-cracks. At- 
tention had not, however, been called to the fact which I propose to 
notice in this paper, that much, if not the whole, of the marine alluvium 
of the Bay of Fundy rests on a submerged terrestrial surface, distinct 
indications of which may be observed in the mud-flats laid bare at low 
tide, and in the deep ditches dug for drainage. 
erous rocks, and separating the estuaries of two small streams, the 
Planche and Missequash ; the latter forming at this place the boundary 
‘between Nova Scotia and New Brunswick. Both of these rivers, as 
well as the other streams emptying themselves into Cumberland Basin, 
have at their mouths extensive tracts of marsh, and in this instance the 
surface of this mud I saw impressions of rain-drops and sun-cracks, 
tracks of sandpipers and crows, and abundance of thé shells of San- 
oesmagtes fusca.* There were also a few long straight furrows, which 
I was told had been produced by the ice in spring. Owing to the firm- 
ness of the mud, they remained (in August) quite sharply marked, 
though in places filled up with new mud. sits .
