I HAVE read with much interest Mr. Horace Brown's account in the GEOLOGICAL MAGAZINE for February, 1896, of the boring for water in the Trias at Stratford-on-Avon. In it he makes brief allusion to the sandstones in the Upper Keuper, and refers to Mr. Howell's statement of the occurrence of certain sandstones near Henley-in-Arden. He does not seem to be aware that similar sandstones are more or less widely spread over a considerable area in some parts of the Midlands, north and north-east of Henley and north-west of Warwick at a higher level, the highest point being 445 feet above the level of the sea. Many years ago I noticed some sandstone in Miss Phillips' park at Edstone not given in the Survey Map, and I informed my friend the late Professor Ramsay of the fact. These sandstones may also be seen in many places, especially in the parish of Rowington. They are exposed on the banks of the canal and along the road leading to Warwick, and were formerly obtained from quarries in the parish now long ago filled up, according to certain old documents in our parish chest, which gives an account of payments made for stone from this place, and our fine church and others in the neighbourhood and some old houses are built of it. When the Great Western Railway was made here a deep cutting through the sandstones was exposed along the line at Finwood in this parish; and lately they were detected when the new line to Henley was constructed. All the higher ridges in this district—they can hardly be called hills—are composed of the sandstones, the lower ground, where the marls and sandstones have been denuded, being formed of the red marls below. Sections are generally rare, as the stone is seldom employed except at Shrewley quarry near here, where the best section of the Upper Keuper beds are exposed. There are about two beds of useful stone: the upper one is inferior to the lower or bottom rock, which is a hard sandstone of some thickness and makes a good building stone, and is used by the Canal Company. This quarry is famous for many interesting fossils so scarce in the Trias, and is noted for the remains of fish, viz., Semionotus, Acrodus (spines and teeth), footprints of Labyrinthodon, and, the rarest of all, moulds of several species of mollusks, the only British locality where any shells have been found. I may add that the wells in the parish are fairly supplied with water from the sandstones, but it is hard and more or less charged with sulphates.
