. a day most agreeably and profitably spent. In company with 

 some friends I remained behind, to make further acquaintance 

 ■with the locality, and this afforded me the opportunity of seeing a 

 very fine collection of Silurian fossils, obtained in the district, by 

 Messrs. Powell and Griffiths, of Builth, who have kindly fur- 

 nished me with a List, a copy of which I now present to you. 

 I cannot leave the subject of the Builth meeting, without con- 

 gratulating you on the opening out of so fine a field for your 

 future operations. 



Our Second Meeting took place on the 22nd of June. 

 It was well attended and passed off satisfactorily. The members 

 assembled at Abergavenny, and travelled by omnibus up the lovely 

 Vale of TJsk, to CrickhoweU ; there we took to our legs and 

 made excellent use of them in ascending by the Darren, to the 

 Pencerig Caleb, or Table mountain ; returning by the Crughwel, 

 which gives its name (conspicuous heap) to the Village at its 

 foot — at the Darren we had in view a very bold escarpment of 

 the uppermost beds of the Old Eed, with its pale yellow Sandstone 

 and purple shaley beds, in both of which we searched, but in vain, 

 for the celebrated Holoptychius scales ; higher up we crossed the 

 Cai-boniferous Limestone, and at the highest point stood on a 

 platform of Millstone Grit, which remains a relic of ancient beds 

 of the Carboniferous series, long since washed away from the 

 mountainous district which stretches towards the North, the East, 

 and the "West, for a considerable distance. Immediately facin"- us, 

 in a southerly direction and across the lovely Valley of the Usk, 

 rose up the fine bold escarpment of Carboniferous Limestone which 

 forms the northern edge of the Monmouthshire Coal and Iron 

 basin. All the points of interest I have mentioned were displayed 

 from the summit of the Pencerig Caleb, and if we were not re- 

 warded for our exertions by the discovery of any rare fossils or 

 plants, those who stood on that famous outlier for the first time 

 must, I think, have felt themselves repaid for the toil of the 

 ascent. 



On the 18th and 19th July, we met at Ludlow, and at the 

 Craven Arms several members of the Dudley and Carodoc Clubs.
