222 GRAVEL AT MORETON-IN-THE-MAESH. [May 1 899, 



could not have come from any other quarter except the south- 

 west. 



Mr. E, A. Martin referred to a paper read in 1887 by the 

 Rev. A. W. Eowe, in which he stated that he had found quartz- 

 tourmalines, containing schorl in abundance, in the neighbourhood 

 of Felsted in Essex. He alhided to the wide range over which 

 Mr. Salter's researches had taken him, and from which specimens 

 had been gathered, and complimented him upon the work that he 

 had accomplished. 



Dr. Hicks said that the evidence produced by Mr. Salter seemed 

 to show that the pebbles of schorl-rock in the Drift on and near the 

 shore of the English Channel had come from the south-west ; but he 

 could not agree with his conclusions that the pebbles of schorl-rock in 

 the Drifts of Hertfordshire and North Middlesex had also come from 

 the same direction. The associated pebbles in the latter areas were 

 of northern derivation ; therefore it was more reasonable to suppose 

 that the schorl-rock had also come from some northern source. 



Mr. 0. A. Shrtjbsole said that the gravel at Moreton-in-the- 

 Marsh was interesting, but its level was comparatively low. He 

 had obtained from it one flint-flake which might be regarded as 

 a ' scraper.' He did not, however, recognize signs of chipping in 

 any of the specimens exhibited. 



Prof. W. W. Watts also spoke. 



The Chairman (Prof. Bonney) said that, before calling upon 

 Mr. Salter to reply, it was only just to him to say that he (the 

 speaker) happened to be fairly well acquainted with the Punter 

 pebbles of the Midlands and with the tourmaline-beariug rocks, 

 both of igneous and of sedimentary origin, in Devon and Cornwall, 

 in the latter of which, so far as he knew, they were more abundant. 

 In the Midland Punter tourmaline occurred in pebbles, which might 

 be called felstones, and in sundry dark, rather compact, quartzose 

 sedimentaries. These, however, so far as he knew, were rather 

 markedly diff'erent from the tourmalinized sedimentaries of the 

 south-west, which also occurred as pebbles in the Pudleigh Salterton 

 conglomerate. The pebbles described by Mr. Salter, as a rule, 

 resembled the latter and not the former type. 



Mr. Salter thought that the chief points in Mr. Puckman's paper 

 were not new. He agreed with the Author in regarding the 

 deposit as fluviatile, probably of Pliocene age. The presence of 

 Triassic debris aud flint, coupled with the absence of Drift composed 

 of Jurassic rocks, was due, in his opinion, to the fact that the 

 Jurassic rocks were covered up by Cretaceous strata, which have 

 since been denuded. The action of floating ice and the indications 

 of a cold period, noted by the Author, were in accord with the 

 speaker's experiences in Southern England. He did not see any 

 trace of man's work in the flints exhibited. 



Replying to the remarks on his own paper, he said that he did 

 not agree with Mr. Peid in assigning an Eocene age to the 

 high-level Drifts of Dorset and Devon. If that were so, the 

 Chalk escarpment would, he thought, have been cut back much
