206 REPORT— 1881. 



In the parisli of Aylestone, Leicester, is a group of syenite boulders ; 

 the longest is 4 ft. X 3 ft. x l-|ft., and is rounded. It was derived from 

 Groby, 5 miles N.W., and lies exposed on the surface, 190 feet above the 

 sea-level. 



A number of boulders in this locality have been described in my 

 previous report, which are far below the height at which they must have 

 been originally deposited. They are now found lying in the alluvium of 

 the valley of the river Soar, having subsided to their present position as 

 the debris was washed away by floods from age to age. 



On the estate of Spinney Hills, at Lodge Farm, Leicester, is a group of 

 boulders of millstone gi-it and granite, the longest 3 ft. x 2 ft. 6 in. x 



1 ft. 9 in. ; the smallest, 2 ft. x 1 ft. x 1 ft. The largest block (millstone grit) 

 is very much rounded, the others (granite) are subangular and angular. 

 There are faint striaj on the millstone grit. The millstone grit may be derived 

 from Stanton, near Melbouriie,Derbyshire; the granites from Mount Sorrel. 

 The former is about 35 miles N.W. ; the latter G miles N.W. The granite 

 blocks are the most numerous. They are 320 feet above the sea-level. 



These boulders were in a deposit of stiff tenacious clay drift, 8 feet 

 deep, and were found lying upon the denuded surface of the rhastic beds, 

 which were uncovered in making a new road. The boulders are found on 

 the S.E. face of the hill, although they have ti'avelled from the N.W. 



In the parish of St. Margaret's, on the estate of Abbey Meadow, 

 Leicester, are three blocks of granite, the longest being 2 ft. x 2 ft. x 1 ft. ; 

 the smallest, 1^ ft. x 1 ft. x 1 ft. They are rounded and subangular, and 

 were derived from Mount Sorrel, G miles N. They were exposed in 

 excavating a new river-bed, and were found lying under 8 feet of coarse 

 pebbly drift (which forms an extensive deposit all over this area), at a 

 height of 165 feet above the sea-level. 



In the parish of Rothley, on the estate of Rothley Temple, Leicester, 

 is a group of four granite boulders, the longest 3 ft. x 2 ft. Gin. x 2ft. ; 

 the smallest, 2 ft. G in. x 2 ft. x 2 ft. They are subangular, and were 

 derived from Mount Sorrel, 2 miles due north. They lie exposed on 

 the surface, 280 feet above the sea-level. 



In the ]3arish of St. Mai^garet's, on the Great Northerir new line of 

 T'ailway, Willowbrook, Leicestei-, are four boulders, the longest 3 ft. x 



2 ft. X 2 ft. ; the smallest 2 ft. x 2 ft. x 1 f t. 3 in. The millstone-grit blocks 

 are rounded ; the altered slate are angular, the granites sub-angular. 



The millstone grit may be derived from Stanton, Derbyshire ; the altered 

 slate from Swithland ; the granite fron Mount Sorrel. Stanton is 35 miles 

 N.W. ; Swithland 5 miles N.W. ; Mount Sorrel 6 miles N. 



These boulders were uncovered in excavations for the line of railway, 

 and were found at vai'ious depths in a drift composed almost entirely of 

 rounded pebbles, 175 feet above the sea-level. Numerous other erratics, 

 but of smaller dimensions, are found scattered throughout the mass. 

 The depth exposed at various points of this coarse pebbly drift varies 

 fi'om 10 to 20 feet, but as the solid rock was in no case reached, it must be 

 much deeper. This deposit must be of immense extent, it having been 

 found at various points over an area of 2 miles by \\ miles. The pebbles 

 constituting this pebbly drift are very much rounded and polished. 



In the parish of St. Maiy's, on the Victoria Park estate, Leicester, is 

 a widely extended group of boulders ; the longest 1^ ft. x 1 ft. X 1 ft. ; 

 the smallest cube of about 10 inches. Many of them are rounded, sub- 

 angular, and angular. They were derived from localities all -round this
