OF ALLUVIAL DISTRICTS AND PLAINS, WHETHER IN- 

 CLINED, ON THE MARGIN OF LAKES, OR ON THE BOR- 

 DERS OF THE OCEAN. 



1st. "What their shape and extent, with the na- 

 ture, height, and general appearance of the hills or 

 mountains, by which they may be bounded." (London 

 Geological Society. 



2d. " The degree and direction of the inclination or 

 slope?" (Ibid.) 



3d. If plains, or alluvial districts, occur on the mar- 

 gin of a lake or lakes, on which side are they, and are 

 their corresponding plains or districts on the opposite 

 side, or in any other direction on the borders of the 

 lake? 



4th. If wells, canals, or other excavations, have 

 been made in such districts, to what depth have they 

 been carried, and what are the appearances that are 

 presented to view ? 



5th. Are fossil trees found in digging in such dis- 

 tricts ? 



6th. If so, at what depth below the surface do they 

 occur, and are they found only at a certain depth, or 

 occasionally distributed from the surface to the bottom 

 of a well, canal, &c. ? 



7th. If trees are thus found in the earth, do they ap- 

 pear to be thrown together promiscuously ; or do the 

 tops appear to lie in one direction, as is the case at 

 Yule, in Yorkshire, England ?
