Report of the Geological Section. 



Our Section shares with the rest of the Field Club the deep 

 sorrow felt at the death of one of its most distinguished members, 

 Mr. Samuel Alexander Stewart. Although an Associate of the 

 Linnaeah Society, and the accomplished author of the standard 

 work " A Flora of the North-East of Ireland," Mr. Stewart also 

 did much original work in Geology. His comprehensive memoir, 

 " A List of the Fossils of the Estuarine Clays of the Counties of 

 Down and Antrim," is published as an Appendix to the Eighth 

 Annual Report of our Field Club, and his valuable paper on "The 

 Mollusca of the Boulder-Clay of the North-East of Ireland," as an 

 Appendix to its Proceedings for 1879-80. Space does not 

 permit to dwell on other papers such as "The Latest Fluctuations 

 of the Sea-level on our own Coast," or "The Boulder-Clay of the 

 North-East of Ireland." We desire rather to record our appre- 

 ciation of Mr. Stewart as a true philosopher, a lover of Nature, a 

 valued friend, ever ready to welcome us, and out of his vast store- 

 house of knowledge to assist and encourage us in our difficulties. 

 His loss to Science is great, to our Geological Section it is 

 irreparable. 



The Committee beg to report that five Excursions were held 

 during the past year by this Section, when the following interesting 

 localities were visited : — Scrabo Hill, April 23rd; Tardree, Sandy 

 Braes, and Carnearney, May 7 th ; Portrush, August 20th : 

 Magheralin, September 3rd ; and Kilcoan, Islandmagee, September 

 17th. The Geological Section, under the leadership of Mr. Robert 

 Bell, also took part in a joint excursion of the various Sections of 

 the Pi eld Club to Armagh on July 2nd. 



At Scrabo Hill the remarkable basic dykes and sills that 

 traverse the Triassic sandstone were carefully examined. At 

 Tardree, Carnearney, and Sandy Braes, lavas of a very different 

 type were studied. Under the guidance of Mr. Strachan, the 

 Tertiary rhyolites for which the district is noted were examined,
