correct, would indicate the following oscillations of level of the 
land. The land, having stood for some time while the upper 
beach was being formed, rose about sixty-five feet, when the 
now-submerged peat grew upon it; it then subsided a little more 
than sixty-five feet, and stood until the lower beach was formed ; 
it then rose again, a few feet, to its present level. 
ReEcENT PEAT.—Considerable portions of some of the hills are 
covered with what is doubtless to be called recent peat. On the 
summits of some of the hills, eg., Prince William’s Seat, 1,825 
feet, it is now being removed by atmospheric denudation, which 
seems to indicate that in such situations the conditions are not 
now as favourable as formerly for its growth and increase. At the 
head of Glencree, above the Reformatory, the turf lies on the 
granite to a depth of from six to twenty feet, and it is said that 
roots of lime and stems of fir, willow, &c., (the fir is unquestion- 
able), are frequently met with in cutting it there; the elevation 
above the sea being 1,500 feet. This also seems to indicate some 
change in atmospheric conditions in such situations; a8 it is 
doubtful if trees could grow there now.
