of very perfect workmanship, and evidently could not be the 

 first implement produced by man. I believe that, if we wish to 

 find the rude tools of which the palaeolithic implements show 

 the developed products, we must go very far back indeed. I 

 cannot therefore on any grounds see that further search will be 

 a useless labour, and I would urge on the Belfast Naturalists' 

 Field Club to let the examination of the Ballyrudder gravels be 

 part of their programme for the ensuing year. 



After some remarks from Mr. Mann Harbison, in which he 

 spoke of the interesting geological and archaeological questions 

 raised by Mr. Knowles. 



Mr. F. W. Lockwood said he had always had an open mind 

 on the subject of the occurrence of human traces in the Boulder 

 Clay and other Glacial and post-glacial deposits in our district. 

 At the same time, he thought the Club would require some 

 further information and further evidence before they would be 

 satisfied that flint implements were found in the Ballyrudder 

 gravels. If that bed could be proved to be of inter-glacial 

 origin, he considered there was more likelihood of articles of 

 human workmanship occurring in it. He wished further 

 information regarding the nature and geological position of the 

 gravel bed in question, and the number and position in the bed 

 of the flints which were now exhibited by Mr. Knowles, and 

 which for his part he could not consider very satisfactory 

 specimens. 



Mr. S. A. Stewart, in reply to a call from the Chair, said, in 

 his opinion the flints found by Mr. Knowles in these gravels, 

 and which he had just examined, did not show any undoubted 

 evidence of human workmanship. 



Mr. R. Lloyd Praeger agreed with Mr. Stewart that the 

 specimens were not satisfactory. At the same time, the 

 question raised was one of high interest to local geologists, and 

 should be thoroughly investigated. The meeting was, he was 

 sure, much indebted to Mr. Knowles for having placed the 

 matter before them in such a lucid manner. As regarded the 

 contention that the beds were of inter-glacial origin, he held
