Members should make early application for rooms, stating that they belong to the Geologists' Association party. It may be necessary for a few members to share rooms, as accommodation may be limited. Those not staying the whole time must state the days for which they require accommodation.

The party will be able to see here nearly 2,000 ft. of New Red (Keuper, Bunter, and Permian) boring cores in possession of Mr. Greenhill, of Puriton Manor. Afterwards visit quarries in Lower Lias Cement Stones, and, if in good enough condition, the Rhaetics shown in the railway cutting.

It is essential to recall the succession of the New Red Rocks as seen on the South Devon Coast in order to appreciate the full significance of the Dunball boring. The descending sequence is as follows:—

Walk to Westford through Rockwell Greens fine Upper Sandstone road cutting. Thence to Hollywell Lake and on to Bunter Conglomerate quarry near Thorn St. Margaret's. Walk to Ridge Farm and from there to Gamlin's, Greenham quarry in Culm Limestone. Afterwards visit Whipcoats quarry. Continue to Canonsleigh Bridge by canal, where Culm Limestones are faulted against Permian Sandstones. Walk on to the Westleigh quarries and thence to Burlescombe Station. Take 4.5 train to Wellington, arriving 4.16. Fare 3½d.

Concerning the Culm Measures, excellent exposures of the limestones of the Lower Culm with intercalated, even Posidonomya-shales in places, and bands and segregations of chert will he seen in numerous quarries, beginning with Greenham quarry and going on to Binnager Bridge, Whipcoats, and the Westleigh quarries; but otherwise the succession of Lower Culm and its relations to Upper Devonian (of Kittifoni on N.) are most unsatisfactory. The chert beds proper, which in normal sequence underlie the limestones, are here either absent or overlapped and faulted out. Each limestone quarry has its special contortions..

Leave Wellington Station 7.3, arrive Taunton 7.20. Total walking distance about 9 miles from Wellington to Burlescombe, and about 5 miles Wellington to Nynehead, Poole, and back.

The main object of this day's excursion will be to obtain an idea of the development of the beds between the Marlstone of the Middle Lias and the Forest Marble that obtains in the neighbourhood of Yeovil. The Upper Lias is practically all sand ("Yeovil Sands"); the Inferior Oolite is very differently developed from what it is in the Cotteswold Hills or in the Bath-Doulting district; and there is no Great Oolite present in the district—Fullers' Earth Clay, With a median band of Fuller's Earth Rock, alone parts the Inferior Oolite from the Forest Marble.

From Pen Mill drive to the foot of Babylon Hill and walk up a shady lane deeply cut in the Yeovil Sands. Thence drive to Half-way House and visit the three quarries there—the Limekiln, Chapel, and Rock-house Quarries. All three present very similar sections. At the bottom is the hard, usually well-bored, waterworn and oyster-covered top-bed of the Sands, and at the bottom of the Top-beds the readily recognised ''Astarte-obliqua-Bed ''of about ''garantianӕ,'' date.Between these two horizons come all that remains to represent the deposits that were made during the ''murchisonӕ, bradfordensis, concavi—and discitӕ ''hemerӕ—at the Limekiln Quarry, 4 feet 3 inches in thickness. Many fossils may be collected here and at Louse Hill Quarry, which is quite close to Half-way House.

The drive will be continued via Yetminster and Ryme to Closeworth, where there is an excellent section of Cornbrash, here extremely fossiliferous.

The return drive to Yeovil will be by way of Stoford, in order that the Members may see the highly instructive sections there, which show the sequence from the Lower Fuller's Earth (with ''Ostrea knorri) ''to the Yeovil Sands. Cost of drive 2/- each. Leave Yeovil (Pen Mill) for London 5.25. arrive Paddington 8.20.
