V. — Direction of Ice-flow in the Neighbourhood of Inverness. 



The direction of the ice-flow in the neighbourhood of Inverness is 

 obviously of great importance in relation to the question referred to the 

 Committee. They have drawn up a list of striaa based on observations 

 made partly by Mr. Home in the course of his survey of the district, 

 which are here given with the sanction of the Director- General of the 

 Geological Survey, and partly by Mr. James Fraser. One instance west 

 of Ethie has been noted by Mr. Hugh Miller. With the view of present- 

 ing these observations in a clearer form they have prepared a strise map 

 of the district extending from Cromarty in the north to Croachy in 

 Strathnairn in the south (fig. 3).
