A very excellent tea was found waiting them on their arrival 

 at the Y.M.C.A. Cafe, after which a short business meeting was 

 held — the President in the chair. 



Time did not permit of a visit to the estuarine deposits, in 

 which so many fossil hazel nuts have been discovered by various 

 members of the Club — Mr. William Gray, the late Canon Grainger 

 and S. A. Stewart — so the remainder of the evening was spent 

 in visiting the various points of interest in the quaint old town 

 which was old and many-memoried when Belfast was yet a village. 

 The return was made to Belfast in the evening after a quietly 

 pleasant afternoon amid historic surroundings. 



MAGHERALIN. 



An excursion of the Geological Section took place on the 

 3rd September, to study the magnificent Chalk sections of 

 Magheralin, and to examine the boulder-clay of the district. The 

 members left Belfast by the 1-50 train for Moira, and thence 

 proceeded to the large Chalk quarry about two miles to the south- 

 west, near to the village of Magheralin. Before entering the main 

 quarry, now extensively worked, a cliff about ten feet high of 

 unstratified red boulder-clay was examined. 131 stones were 

 counted; 14 of these were chalk and flint from the subjacent 

 rock ; the remaining 117 were erratics, including basalts, dolerites, 

 grits, granites, mica-schists, quartzites, Tornamoney eurite, gabbros, 

 Cushendun Old Red conglomerate, Cushendall porphyry, Lough 

 Neagh clay-ironstone, &c, many evidently derived from N. 

 and N.N.E., but there were also indications of a north-westerly 

 source. An erratic of dolerite lying on the top of the Chalk 

 measured 2ft 6in x 2ft x ift 3m. No specimens of Ailsa Craig 

 riebeckite-eurite were found, but on the excursion last year to the 

 Moira district this rock was noted at the Maghaberry quarries, one 

 specimen measuring i2in x yin x 6in, the largest found in our 

 boulder-clays, except one noted by Mr. Bell a few years ago at
