undulating and wooded country, leaving Penarth docks and the 

 fine Rhaetic section on the left, it was a relief to descend on terra 

 firma at the Wenvoe Arms, Cadoxton juxta Barry, where the 

 usual signs of large works in progress were seen in lounging 

 navvys and a noisy bar. After a few minutes' delay below on the 

 newly made line connecting Cardiff with Barry, a locomotive 

 with saloon carriage attached was seen steaming up from the 

 west, which Mr. John Eobinson, the Resident Engineer of the 

 Docks, and Mr. C. H. Walker, the nephew of the great contractor 

 of the works, had kindly put at the disposal of the members. 

 Under their guidance the various details of this truly great work 

 were pointed out. Steaming away to the E., the foreshore — 

 from which is obtained some of the best blocks of Limestone and 

 Red Sandstone for the masonry of the docks — was reached by a 

 temporary line of rails. The section exposed here was New Red 

 Marl resting upon a Limestone Conglomerate of varying thickness, 

 below which came horizontal beds of Red Sandstone, with inter- 

 calations of greenish bands. Returning westwards in the direction 

 of the docks, a fine section of Keuper Marls was passed to the 

 N., a pretty little fault bringing down the Lower Lias beds on 

 the W. Passing on to the middle of the works the members 

 alighted, and then were enabled to appreciate the magnitude of 

 the undertaking. Barry Island, surrounded by water at high tides, 

 has been connected with the mainland by a raised causeway, 

 cutting off the waters of the Channel on the E. and W. The large 

 bay on the E., 110 acres in extent, is to be converted into ac- 

 commodation for shipping ; for this purpose breakwaters have 

 been run out from the mainland and island — a temporary sea bank 

 at present serving the purpose of a dam to exclude the waters. 

 Inside this bank, which will be cleared away when the work is 

 finished, Dock gates will be erected, the foundation work being 

 now in progress; the width of the gates to be 80 feet, and the 

 depth of the water at ordinary low tides 12ft. 6in. These gates 

 admit to a fine deep basin, 600 feet long by 500 feet wide, about
