from the Blue Ridge, and its streams were feeding the Mesozoic 
areas. The ferns, cycads, &c., were furnished with a mi 
equable and moist climate by fogs from the Gulf Winds. 
In this part of his argument it is difficult to follow the author, 
who would produce the glaciers by the cold winds sweeping east 
and north-east unchecked from the Pacific, while an “immense 
growth of coniferous trees covered the hills.” 
The problems with which Prof. Fontaine closes his paper, as to 
whether some of the drift in the northern States attributed to the 
Glacial period may not be much older; and whether there may 
not be drift deposits around the southern prolongation of the 
Appalachian chain. thus carrying an ice period into the far South 
to meet that of Prof. Agassiz in Brazil, are, as he says, well worth 
the attention of geologists. 
In this paper the main points of interest are his belt of stones 
in the north-west and under the Catoctin range; his criticism of 
Schimper’s determination of Equisetum rogersit, and his associa- 
tion of the ferns with the “ Rheetic ” beds, or their contempora- 
ries, his establishing the drift matter of Azoic fragments in clay 
as passing under the Cretaceous in Maryland, and his conclusions 
as to the great eroding action of a glacier previous to or coinci- 
dent with the laying down of this drift. 
Mr. Russell's Paper. —This is concerned nominally with the 
England and British American Trias as well. These rocks and 
the protecting action of their traps in the bay of Fundy are first 
considered, and the tidal action on the soft muds is afterwards 
referred to as a good example of the kind of action which pro- 
_ duced these soft ripple-marked shales. 
In endeavoring to give, from a few localities in New Jersey, a 
general idea of the characters of these shales and sandstones, it 
must be confessed that either their variety is singularly curtailed 
on the crossing of the Delaware into New Jersey, or many of 
the diverse representatives mentioned by Messrs. Frazer, Heinrich 
and Fontaine must here be classed under the same names. 
Note A refers to a south-westward dip of the Trias just east of — 
the Blue Ridge in Virginia. Fontaine gives this dip of his “ New — 
Jersey belt” as north-west, while Heinrich’s section makes it 
east or south-east. 
An italicised paragraph seems to claim novelty for the conclu- 
Sion to be drawn from the fact that in New —* the dip of
