These five feet are made up of boulders resting at various angles, mixed with boulder 

 clay, flakes, cores, &c. I would like to have your opinion as a geologist as to how the 

 boulder clay came there. I give you a rough sketch on the opposite page showing the 

 position of the section I refer to. 



Yours very truly,

Remarks by Members of Investigating Committee. 



(IN ALPHABETICAL ORDER.) 



Mr. Anderson agrees with Mr. Stewart's statement in every 

 particular, and says farther for himself that he did not observe 

 any deposit of boulder clay proper " in situ^' at either of the 

 two stations examined. His opinion is that the deposit in both 

 cases is one and the same. The underlying Estuary Clay was 

 exposed only at that further to the north. 



East Hillbrook, \2th June^ 1886. 



J. ANDERSON. 



That flakes are only found on the surface, or at such depths 

 in the gravels that proved they were not deposited with the 

 gravels, but were evidently manufactured after the beds had 

 attained their present elevation. 



G. DONALDSON. 



The systematic examination of the beds was conducted with 

 a member of committee at the top of the bank to see that no 

 flint fell from the top. This investigation was suspended at a 

 depth of eleven feet six. Up to this there was no indication 

 whatever of worked flakes or lower flints of any kind for the last 

 five feet. At this depth a very rough bed of stones was reached. 

 After some consultation and examination of the specimens found, 

 the committee (standing some distance from the cutting) resolved 

 to cut down deeper. Up to this time the workmen were 

 standing in the cutting and commenced their work again as 

 some members of the committee came forward, Mr. Praeger 

 being first, and followed by me and Mr. M'Kee. Mr. Praeger
