IN GALLOtTAY.

falls. In the bed of the former, three-fourths of 

 ^ mile north of Loch Dee, we found in the granite, 

 a large bed of reddish felspar-porphjrv, 40 feet 

 thick, seemingly vertical, and we traced it at least 

 60 yards. Its direction is S. E. by S. 



12. One mile farther down the CfOoran Lane, 

 we came upon another bed of felspar-porphyry 

 m the granite, to be seen for 30 yards. Its di- 

 rection is about S. E. by S., apparently vertical. 



13. Several yards farther down still, is another 

 bed in the granite, seemingly in the same direc- 

 tion. 



14. In the first small rivulet we came to, fal- 

 ling into the Dee on its left bank, we found ano- 

 ther bed of reddish felspar-porphyry in the gra- 

 nite, lying in the sam.e direction as before, and to 

 all appearance vertical. 



15. Two miles nearly below Loch Dee, that is^ 

 down the river to the eastward, opposite a small 

 burn on the right bank of the river falling down 

 the Hill of Craigencaillie, and another on the 

 brae face of the low Hill of Garrery, is the junc- 

 tion of the granite and the stratified rock. It 

 runs directly across the river, and is distinctly to 

 be seen. The rock here, resting on the granite^ 

 is compact gneiss, of many yards in thickness, and 

 the strata vertical. The direction is E. N. E. I 

 could neither here, nor any where else in this 

 quarter, perceive a junction of the compact gneis'^ 

 with the grey-wacke.
