With the exception of an article written by me for Sir William Willcocks and published in his “Nile in 1904,” and a reference to the relations of the Eocene and Cretaceous in the oasis of Kharga in a paper read before the Geological Society in 1905, nothing has, I believe, been published on the water-supply and geology of this district since Dr. Ball's report in 1900.

The rocks composing Basutoland belong to the Stormberg Series of the Karroo System. They cover a much larger area than Basutoland, extending into the Orange River Colony on the west and north, on the south and east into Cape Colony and Natal, and, I am informed, across the Vaal into the Transvaal. The area is thus not less than 45,000 square miles. The whole of that part of the Orange River Colony known as “the Conquered Territory,” east of a line drawn from Thaba 'Nchu to Vrede, is occupied by the whole or portions of these rocks.

Corallum conical and, as a rule, gently curved, though often straight; a short broad outline is not uncommon. The epitheca has well-marked longitudinal ribbing, sometimes obscured by fine annular striations in the neighbourhood of the calyx; slight constrictions of growth may occur, but there is never an interrution in the continuity of the epitheca. Good figures are given both by Milne-Edwards & Haime and by de Koninck.

When we were gathering material and data for that portion of the paper on Kent and Sussex dealing with the Dover section we made careful search for Uintacrinus both on the top of the cliff, north of St. Margaret's Bay, and on the high ground immediately to the westward of the cliff. We failed to find it in either situation, and there were no quarries close to the coast. A thick tabular band of flint is seen at the top of the cliff at the north side of St. Margaret's Bay, and this we believe to be the same table of flint which we have called in Thanet the “Whitaker 3-inch tabular band.” If our inference be correct, we are here within 21 feet of the “Barrois sponge-bed,” which forms the basement-bed of the Uintacrinus-band in Thanet.

The known occurrences of Actinocamax verus in this zone are comparatively few. Northfleet in Kent, Micheldever in Hampshire, and Great Fimber in Yorkshire are our only records.

From the point K northward to the stile leading to the road on to the Towan Head the killas comes to the top, but just short of the stile there is a section of another hill-wash-dune showing about 5 feet, but not exposing the base. Land shells are abundant towards the top, especially at 1 ft. 3 in. and 2 feet from the surface, but the lower portion contains very few. The Helix nemoralis zone lies just below. This section yielded the flint flake found by Mr. Warren.
