force so that now in man}^ places between the changed and 

 unchanged rocks, there are no defined boundaries, one irregu- 

 larly merging into the other. In Ireland the older quartz^^tes 

 after sedimentary rocks (originalh^ Algonkians or Pre-Cam- 

 brians, some probably being Cambrians or even Post- 

 Cambrians) generally appear to occur in more or less well 

 defined tracts. This, however, is more apparent than real, 

 because if minutel)^ w^orked out, the}" in places are found to be 

 interlaced with micalyte or other foreign schists. Upthrusting 

 has in many places made distinct longitudinal boundaries or 

 even transverse boundaries, as the fioors of the faults are of 

 the harder rocks ; not however necessarily one continued bed, 

 as the more friable beds, or portions of beds, were ground 

 awaj^, and the fault line may creep across the beds, or along a 

 line of weakness, thus crossing them more or less transversely.

BEI.FAST NATURAI^ISTS' FIEI.D CI.UB. 



September 17th. — Last excursion of the season to Ardglass and Kil- 

 lough. A party of ninety travelled by 10.30 train over the new line to 

 Ardglass. In spite of the lateness of the season the botanists did good 

 work, Mr. Praeger being especially fortunate, securing Papavti- hybriduvi 

 and Festuca j'igida, both of which are extremely rare in the north east. 

 Other species observed were CEnanthe lachenalii. Ononis arvensis, Papaver 

 rhceas, Lamiiim intermedium, L. amplexicauh, Ballota alba, Sinapis alba, Schlero- 

 chloa loliacea. Uptilted Silurian grits, beautifully ice-worn, were inspected 

 on the shore, where also a good section of Glacial and Post-glacial de- 

 posits was seen. Tea was provided at Ardglass. and the party returned 

 to Belfast by the 6.35 train.
