between the ' main pit ' and the small exposure of the shelly clay 160 

 yards south- west of the ' main pit.' Other bores were put down to the 

 north-east of the ' main pit,' to prove the extension in that direction. 



The borer's 'Journal,' stating the nature of the materials with the 

 respective thicknesses, is given in a tabular form below. Mr. Fraser, who 

 made the levelling observations in connection with the work carried out 

 by the Committee, determined the height of the surface of the ground at 

 each bore. He has added columns to the borer's 'Journal,' showing 

 the total depths of the respective deposits and the total heights above 

 sea level. He has also given the distance of each bore from No. 1 bore 

 at the ' main pit.'
