ON THK ERRATIC BLOCKS OF ENGLAND AND WALES. 89 



at least some, of the so-called boulders rising through the greensward in a 

 line with the Berry-Stone, and on the west of it, are indications of its subsoil 

 prolongation in that direction. 



A degree of resemblance to the Auswcll Rock may be the result of simi- 

 larity of composition and of exposure to corresponding treatment. It may 

 be sufficient, perhaps, to justify the question, " Has the southern been derived 

 from the northern mass?" but not sufficient to justify an affirmative reply. 



I cannot conclude this note without expressing my gratitude to Mr. Paige- 

 Browne for having directed my attention to phenomena so unexpected and 

 so striking as the Leigh boulders, and which are certainly amongst the most 

 pronounced indications of ice-transportation known to me in Devonshire. 



Leicestershire. 

 Mr. J. Plant, of Leicester, reports as follows: — 



IsoJa ted Bo ulde rs. 



Loseby, Leicestershire, about 9 miles from Leicester. Gravel-pit, in map 

 under letter o in Loseby. 4| feet long, 3 feet wide, 3| feet deep. Sharp 

 angles and edges on one side, the other side rounded off. Long shape ; never 

 moved by man ; S.E. by S. No groovings can be seen. Granite. About 

 650 feet above the sea at mean tide Liverpool. 



The erratic is in a gravel-pit of " drift," flint, rounded pebbles of liver- 

 quartz, &c. ; this gravel-bed forms part of a long "ridge" of drift-gravel ; the 

 pit opened is 20 feet deep, and rests upon gravel, which again lies upon the 

 upper clays of " Lower Lias." 



This "erratic" is 10 miles distant from its nearest possible source, and is 

 the largest of this kind that I have found at that distance. It is reported to 

 me that when working (some years ago) this gravel-pit, a large block of pure 

 coal (as large as this " erratic ") was found, but it was speedily utilized for 

 domestic purposes. 



I was informed of another block of coal (large size) found in a gravel-pit at 

 Beeby, 4 miles west of Loseby. These blocks of coal must have travelled in 

 ice, as they would certainly have been broken up by any other means of 

 transport, such as water. Both blocks were buried many feet in the gravel. 



i have never met with any " erratics " of any kind on the " marlstonc," 

 and, in fact, there is very little " drift " upon any of it, the red rock being 

 nearly at the surface ; and hence the name of these marlstone-districts, " the 

 red lands." The mean height of the marlstone is G80 feet, all lying south, 

 south-east, and east of Leicester, and the mean height of Chain wood Forest 

 (the presumed source of these erratic blocks of granite, syenite, greenstone) 

 is about 700 feet ; there are a few peaks 840 feet, and one, Bardon Hill, 

 802 feet. 



Groups of Boulders. 



Group No. 1. — At Evington, about 1 mile east of the town of Leicester. 

 The size of the boulders is from 3 feet x 2| x 1| down to cubic blocks about 

 1 foot on each side. The greater part have sharp angles and edges, and when 

 free of clay and sand the rock-surface is very fresh, not at all weathered ; 

 the grits and sandstone arc rounded and worn. 



Many of the limestone blocks are covered with grooves and scratches. 

 Iloeks at south end of Charnwood Forest would supply the granite, syenite, and
