KEPOUT — lS9i. 



Journal of Bores at Lindsay's Well, Chapelhall — (continued). 



With regard to Nos. 5 and 6, -which were put down to divide the space 

 between the others, and touch any bed that might extend diagonally 

 between them, either to S.W. or S.E., Mr. Pollock wrote: 'I have 

 found no difference in the stuff I went through.' And with reference to 

 No. 7, which was put down in the expectation of touching the rock at 

 24 feet from the bottom of the well (or 40 feet from the surface), as 

 reported, he wrote : ' I have finished bore in well, and put it down 47 feet 

 and got no rock, and found no difference in clay from toj) to bottom ; it 

 was all blue clay and small free-stones.

' Plains, April 11, 1894.' 



Further, in answer to an inquiry on the point, Mr. Pollock wrote : — 



' I don't believe the ground had been disturbed in any way, at any of 

 the places where I put down bores at Chapelhall, because they were all 

 mostly the same — the brown clay on the top, then the blue clay under it. 

 They all seemed to be quite naturally formed, and in no way disturbed. 

 Even the bottom of the well was the same. 



' J. P.' 



The Committee may here remark that, as is well known, a deposit of 

 boulder-clay is generally browner in colour and looser in texture towards 

 the top, owing to the action of the ordinary weathering agencies upon it, 

 and not to any special change of conditions during its deposition. 



Mr. Macconochie reports as follows : — ■ 



' I was present at Chapelhall (April 6, 1894) when Mr. Pollock brought 

 up the materials from bores Nos. 1 to 6, from depths exceeding 14 feet. 

 They con.sisted of the ordinary boulder-clay of the Chapelhall well section. 



'A. Macconochie.' 



III. Conclusion. 



As the result of their investigations, the Committee beg to state that 

 they have found no evidence in proof of the occurrence of shelly clay at 

 Chapelhall either in the original well section or in the trial bores. 



The Committee recommend that they should be reappointed with a 

 grant to investigate the shelly clays at Tangy Glen, near Campbeltown, and 

 on the Lag and Rosie in Arran.
