278 EEPOET— 1891. 



otberwise specified) the erratics in question Lave been extracted. 

 Glacial striae may be seen on the mountain limestone at various points 

 some five to six miles to the north-east, near Clitheroe : these stria?, as 

 shown by the geological survey map, point a few degrees west of south. 



The two rocks which seem to be most abundantly represented among 

 the erratics found near Stonyhurst are — first, a compact, deep, purplish 

 red Permian marl, which is slightly exposed four miles to the north-east, 

 near Clitheroe ; secondly, a compact yellow sandstone, very persistently 

 characterised by speckles of brown iron-oxide. I have coupled this rock 

 with the one first mentioned because I think it likely that it, too, is 

 Permian or Triassic. The erratics composed of these two rocks all seem 

 to be of quite small size. 



Almost as numerous as the above mentioned, and far exceeding them 

 in size, are boulders composed of various andesitic rocks, showing a strong 

 family likeness, perfectly fresh and hard, of a grey colour, slightly varied 

 in different specimens by greenish and bluish tints. Many of these 

 measure a full cubic foot or more, and show well all the characters of 

 ice-borne boulders. Most of them are certainly identical with rocks in 

 Borrowdale (andesites of the well-known Borrowdale series). 



Next, perhaps, in frequency of occurrence come small rounded or 

 flattened boulders of a fine-grained rose-coloured rock of syenitic aspect. 



Of another rock, also of syenitic aspect, but much larger grained, I 

 procured a single bouldei", the size of an infant's head, from a field-drain 

 close to the college. 



[Mr. Kendall is of opinion that both of these are varieties of the 

 Buttermere granophyre.] 



A single piece of a compact, homogeneous pink rhyolite, picked up 

 within a mile or two of Stonyhurst. 



This specimen seems to me certainly identical with a similar pink 

 rhyolite, composing a remarkable group of large boulders a mile or two 

 west of Dungeon Ghyll Hotel, near Grasmere, by the side of a broad 

 path or cart-track leading up the valley to the west from the back of 

 the hotel. Some of the boulders measured two or three cubic feet. 



A few hundred feet above the college, on the slope of Longridge Pell, 

 boulders of other than local rocks become very rare ; at a height of 1,10(> 

 feet, or so, all drift has disappeared, while on the top, at a height of 

 some 1,300 feet, I have often walked for miles, examining ground, walls, 

 and cairn, and have never been able to find a single woi-n pebble or 

 boulder — nothing but angular fragments of the local sandstone. On 

 Fairsnape Fell, to the north, at about the same height, I have noticed 

 the same fact.
