which the streams that at present flow in them ? If so, 

 at what height ahove the bottom of the vallies do they 

 run, and what appears to have been the direction of 

 such current ? 



9th. Are there any considerable quantities of allu- 

 vial grounds, where the waters of such vallies are dis- 

 charged into the vallies adjacent to the mountains ? 

 and have they increased materially within the memory 

 of man ? If so, what is their extent, and probable in- 

 crease, annually ? 



10th. Are there to be found on the tops or sides of 

 mountains, composed principally of granite, or primi- 

 tive limestone, detached masses of transition, or se- 

 condary rocks, out of place ? If So, on which side of 

 the mountain are they found, and at what Jieight above 

 its base ? And also, of what size, description, or cha- 

 racter, are such masses ; at what distance are such 

 rocks found in place, and in what direction from the 

 masses so found ? 



The same remarks are applicable to mountains, the 

 rocks of which are of a different order, (viz.) 



llth. Are there to be found on transition mountains, 

 masses of secondary rocks ? on which side, and at 

 what height ? At what distance, and in what direction, 

 are rocks of the same kind found in place ? 



lth. On a range of mountains of secondary forma- 

 tion, are there to be found masses of primitive rocks 

 such as granite, or those of transition ? &c. &c.
