the Upper Basalt, which was much decomposed. A few cavities 

 containing analcime were seen, and one fine specimen obtained. 

 The party then returned to Templepatrick, and the quarry close 

 to the railway station was visited, where formerly a fine exposure 

 of chalk, Lower Basalt, and rhyolite was visible, and it is to Mr. 

 M'Henry, M.R.I. A., that we owe the very interesting discovery, 

 from the study of this section, that the rhyolite is intrusive 

 into the Lower Basalts, while from further evidence obtained at 

 Ballypalady and Glenarm he showed it to be older than the Upper 

 Basalts. He therefore regards the rhyolite as of mid-basaltic age, 

 and considers it highly probable that the granite of the Mourne 

 Mountains is contemporaneous with the rhyolite of County 

 Antrim. The Templepatrick rhyolite is of a pale grey colour, 

 and under the microscope shows a fine-grained ground mass, with 

 phenocrysts of quartz, mica, and sanidine. The last object of 

 interest visited was a very large " erratic " of basalt in a field near 

 Templepatrick Railway Station. 



BOYNE VALLEY. 



The Summer Session was opened on 22nd May, when fifty 

 members and friends visited the Boyne Valley, under the guidance 

 of Mr. \V. J. Fennell, F.R.I. B. A. The party entrained at the 

 Great Northern Railway Station at 7-30 a.m in specially reserved 

 carriages, and arrived in Drogheda at 9-40. Here vehicles were 

 waiting to convey the party up to the lovely Boyne Valley, to the 

 scene of that battle of which Northerners so insistently remind 

 each other at certain seasons. The party dismounted and viewed 

 the obelisk erected to commemorate the death of Duke 

 Schomberg, who was shot on this spot while rallying his troops. 

 The quiet beauties of the scene made it difficult to realise the 

 fierce struggle which took place on the banks and in mid-stream 

 on the 1st July, 1690, when William of Orange's forces crossed 

 the river to meet King James's men on the southern bank.
