{91b} A list of Scandinavian boulders, which have been found in Lincolnshire is given by Mr. T. Sheppard, in the “Glacialists’ Magazine,” vol. iii, 1895, p. 129. Notices of lakeland boulders are given in the “Naturalist” of 1897, pp. 67, 103–104, 195–6, 283–4; and of 1898, pp. 17–20,85–87, 133–138, 221–224. In the Quarterly Journal of the Geological Society for May, 1885, Mr. Jukes Brown gives the general range of the boulder clay in Lincolnshire, while its range of flanking rocks in our own more immediate neighbourhood is treated of in the Government Geological Survey of “Lincoln and the Country around,” pp. 2, 122–129, 155, 156. {91c} The average rate of a glacier has been computed at 64 inches for the four summer months; in other cases one inch a day. The progress, of course, varies with the slope or smoothness of its bed, and is more rapid in the centre than at the sides, where it scrapes against flanking rocks. {92} Sydney B. J.

This clay indeed receives its name Kimeridge, from a Dorset village, on the coast, near Corfe Castle and Poole. {94a} Mr. Jeans, in “Murrey’s Handbook of Lincolnshire,” [p. 6] puts the total thickness of the various cretaceous formations at “about 1,000ft.” {94b} Geological Survey, pp. 207–209. {95a} Ibedem. {95b} Quarterly Journal, Geol.

In “A Selection of Papers relative to the County of Lincoln,” read before the Lincolnshire Topographical Society, published by W. and B. Brooke, 1843, there is a paper by W. Bedford on the Geology of Lincoln. He divides the rocks into 26 beds, commencing from the north of the Cathedral and descending to the bed of the Witham. He gives a very interesting coloured section, showing these different strata, where the springs arise beneath the oolite; then the ferruginous gravels, the clunch clay, and the lias underlaying all. {97d} Geolog.
