276 [Proc. B.N.F.C., 



Again mounting, the party drove to Ballygalley Head, a fine 

 mass of intrusive trap that stands boldly out into the channel. 

 Its seaward face shows huge columns tilted at a slight angle, 

 while on each side the trap is flanked by the Chalk through 

 which it has forced its way. Here the botanists of the party 

 put in a claim to share the honours of the day, and exhibited as 

 their trophies the field chamomile {Matricaria C/iamomilla), 

 a rare plant, perhaps introduced with American seed, which 

 appears to be spreading in Antrim ; a rare thistle, Onopordon 

 Acanthium, not native in Ireland ; several rare mosses 

 from the bare rocks on the summit of the headland ; and an 

 uncommon rose {Rosa mollis) found at Waterloo. Climbing 

 up the steep hillside, the party were soon reposing on the short 

 green turf on the hilltop, an object of admiration to a number 

 of rabbits and a fine herd of inquisitive cattle. The warm 

 sunshine and drowsy hum of insect life, with the faint murmur 

 of the water lapping the rocks three hundred feet below, had a 

 soothing, if not a lazy effect, and some time was spent in 

 leisurely admiring the extensive and beautiful view that 

 stretched both northward and southward, and in letting the eye 

 wander along the blue extent of distant Scottish shore till it 

 lost itself among the dim purple peaks of Arran. But the 

 secretary's shrill whistle soon sounded the advance, and 

 descending the steep slope, the party proceeded to a spot by the 

 wayside about a mile north of Ballygalley Castle, where an 

 interesting glacial deposit occurs. It consists of coarse gravel, 

 and underlies some thirty feet of upper boulder clay, and has 

 yielded a number of Arctic shells. Near this it was that a 

 mammoth's tooth was found some years ago, the geological 

 origin of which excited discussion at more than one of the 

 Club meetings. On the present occasion the gravel bed was 

 almost hidden by a quantity of boulder clay that had fallen 

 from above, and some fragments of shells were all that 

 rewarded the labours of the party. Once again proceeding, 

 no halt was made till within a mile of Glenarm, where an 

 extensive quarry in the Chalk excited attention, furnishing, as.
