2. The submergence of part of eastern North America, durin<>- 

 which the marine beds of the Charaplain period were formed, 

 was not participated in by the southern coast of Nova Scotia. 



o. To explain the movement of land ice from the Arctic regions 

 southwards, it is not necessary to suppose that the continent 

 to the north must have been greatly elevated, nor do the facts 

 connected with the distribution of the drift agree with such a 

 supposition. 



4. That there was some elevation of northern lands during the 

 glacial period is, however, probable : Firstbj, because all the 

 oscillations of level of the lands in the northern hemisphere 

 since the glacial period, with which we are acquainted, have 

 been greatest' towards the pole; and secondly, because arise 

 of land sufficient to prevent the entrance of heated currents to 

 the polar basui, would occasion a great accumulation of ice in 

 the circumpolar regions, by the heat of the tropical and sub- 

 tropical waters being spent in evaporation instead of, as at 

 present, in melting the ice within the Arctic circle. 



5. The drift-beds were formed during the retreat of the ice, and 

 not during its greatest development. 



6. Terraces and stratified beds in lateral valleys, Avere formed 

 when these were filled with water, dammed back by the glaciers 

 that still flowed dovrn the main valleys.

 This county, known untU lately as the county of Sydney, is the 

 north-east county of Nova Scotia proper. It is bounded on the north 

 by Northumberland strait, Avhich seijarates it from Prince Edward 

 Island, — on the east by St. George's Bay, — on the south by the 

 county of Guysboro', — and on the west by the county of Pictou. It 

 is somewhat mountainous, and contains numerous small lakes and 

 streams. The principal mountains arc the Antigonish mountains, 

 whose corner nearest to the town of Antigonish is about three miles 

 to the north-west. Considering this range as sub-triangular, one
