n conclusion I would remark Ist. that where granite. 
occurs in horizontal veins as in fig. 1, it does not appear 
probable that they were deposited in this situation, but 
rather in perpendicular ones. For I believe there is suffi- 
cient evidence to prove that the mica-slate, was once de- 
posited in horizontal beds and that the present vertical 
position was caused by an — of force below suffi-

Geological Remarks. 
A SINGLE township affords but little room for geological 
investigation. The inclination of the strata can be obser- 
ved, and the relative position. of the rocks; but it is only 
on the large scale that the science can be studied to ad- 
vantage. or any tae be formed which will rationally 
account for all the fac 
The principal nook in Salisbury are mica-slate and 
Fein a limestone. The former is most abundant and
