dingle to get out some slabs of the Llandeilo flag ready for more careful 

 splitting and closer examination, and here a moat lively scene soon presented 

 itself. The narrow dingle was soon filled by enthusiastic geologists, hammering 

 away in such close proximity that it was a marvel that no accident happened. 

 A few specimens of the Ampyx nudus and Ogygia Buchii, together with one 

 or two of Diplof/rapsus pristis, with here and there a Lingula or a small 

 portion of Trinncleus, were all that were found when the President's whistle 

 sounded and the march for Pencerrig began. 



On their emerging from the dingle some ladies on horseback joined 

 the party and added much to the picturesque effect of the group of naturalists. 

 The grounds of Pencerrig were soon reached, and a direct line was taken 

 across the park for the quarry at the pond-head. Here the upper Llandovery 

 rocks and the Llandeilo flag are developed in the quarry, while the Wenlock 

 shale appears in the bed of the Melton brook, which at this point runs from 

 the pond. Excellent specimens of the Pentamcrus uhlongus were also readily 

 obtained from the upper Llandovery rock in the quarry under the guidance 

 of Ml. Grifliths, who knew exactly the proper place to look for them, and from 

 the shale in the brook specimens of Graptolites ludensis, and O. Murckisoni 

 were obtained. The brook here dives down amongst dense foliage into the 

 deep gloom of a narrow, shaded dingle. A whisper was breathed that fresh- 

 water lobsters lived in it, and one gentleman bent on verifying the fact set 

 out to hunt, and quickly returned with a fine cray-fish or craw-fish (Astacus 

 fiuviatilis), which he presented to the President. The time had now arrived 

 for the Address, and the party arranged themselves on the grass, and on the 

 banks, and in the pleasant shadow of the trees, and listened to the following 

 iustiuctive address.
