80 kepokt — 1877. 



on tho 28th of the following September, and on the next day we proceeded 

 to the hamlet of East Leigh, also in Harberton parish. On our way thither 

 Mr. Paige-Browne directed my attention to the frequent occurrence of large 

 stones, of a reddish colour, in the foundation courses of hedges and other 

 rough walls, and all differing strikingly from the slate or "shillet" of tbe 

 district. These were the outposts, so to speak, of the boulders we were to 

 examine ; and whilst they were considerably smaller than most of the spe- 

 cimens to be visited, they were so large as to render it probable that they 

 had not been transported by man from any great distance, but had been 

 found near at band and utilized. 



At East Leigh, about a mile north-westerly from Englebourne House, and 

 nearly as far in a south-westerly direction from the village of Harberton, 

 boulders arc very numerous and of great size. They are generally angular 

 and subangular, but with one face more or less rounded, and even polished, 

 but without any scratches or strise. They are all of a red colour and jaspi- 

 deous aspect, and so siliceous as to scratch glass readily. One of them, pro- 

 bably the largest of the group — so near a cottage-door that we felt called 

 on to apologize to the inmates for our seeming intrusiveness when engaged 

 in examining it — mcasuics 17x10x5 feet, and, taking its specific gravity 

 at 2-5, its weight can be little less thau 60 tons. It lies on the common soft 

 shillet of the district, and is certainly a travelled block. This is, no doubt, 

 the history of all the numerous blocks near it. 



A short distance towards the north-west there is in a field a large mass 

 of the same kind of rock, rising above the soil, and probably in situ, having 

 on it a loose, but in all likelihood untravelled, block of the same character. 

 Both of them, and especially the upper one, are smoothed and rounded on 

 certain parts of the surface. Indeed one portion of the upper stone has a 

 polish a lapidary might envy ; but it was no doubt produced by the rubbing 

 of cattle. Neither of the stones is scratched or striated. 



East of these blocks, in the adjoining field, is the striking and abrupt pile 

 known as Berry-Stone Rock. It is distinctly stratified and jointed, and is, 

 I have no doubt, the undisturbed remnant of a much larger mass — the parent 

 of all the numerous boulders covering the district immediately on the south ; 

 and it seems more than probable that some of the isolated masses rising above 

 the greensward, not far from the Hock, as well as in the adjacent field on 

 the west, are untravelled, undisturbed prolongations of the same mass. 



In tho south face of the pile, which is almost vertical, Mr. Paige-Browne 

 detected fragments of crinoidal stems, and we found subsequently obscure 

 casts of Brachiopods, all of which we left uutouched. Information has 

 reached me that Mr. Champcrnowne, E.G.S., of Darlington Hall, has since 

 found several corals in the same mass, but none of them sufficiently perfect 

 for specific identification. 



Mr. Paige-Browne informed me that a common mode of freeiug cultivated 

 ground from boulders was to dig deep adjacent pits, into which, by under- 

 mining, they were caused to fall, and were then buried. The process, how- 

 ever, being attended with risk, is not now much resorted to, as the workmen 

 object to it. 



Whilst descending to Leigh Bridge, on the cast of Berry-8tone Hock, we 

 entered a very small field, in which the boulders were very numerous, and 

 many of them of great size. Here we found an intelligent villager named 

 Heath, who stated that all the blocks of which he had had experience lay either 

 in the common soil, or on rock utterly unlike themselves ; that unsuspected 

 boulders of precisely the same character were frequently encountered iii tho
