1870. | HARKNESS—WASTDALE-CRAG BLOCKS. 519 
farm-buildings in the village of Cliburn. They do not, however, 
seem to occur in the country which lies west of a line from Shap to 
Cliburn. 
They can be recognized about two miles N.E. of Cliburn, at Tem- 
ple Sowerby. I learn from Professor Phillips that he has seen 
Wastdale-Crag blocks at Long Wathby, on the east side of the river 
Eden, at a distance of 54 miles north from Cliburn; and this is the 
most northern lmit which has been yet recognized of the occur- 
rence of these blocks. Long Wathby is four miles N.E. of Pen- 
rith. In the interval between those two places no Wastdale-Crag 
blocks have been found, nor are there any traces of them in the 
district between Penrith and Cliburn; and in the country due 8. and 
S.W. of Penrith their occurrence is unknown. 
From the south side of Wastdale Crag, the granite blocks have 
taken a 8.E. course. 
They are found as far south as Tebay; and I learn from Mr. 
M‘K. Hughes that, although few of them cross the river Lune, he has 
met with them at a distance of about one-third of a mile south of the 
village of Langdale, which is about half a mile south of the Lune. 
From this spot the direction of their course has an E.S.E. boundary, 
which leads into the valley of the Eden. In the upper portion of 
this valley, they are not seen so far south as Kirkby Stephen, but 
about 24 miles to the N.N.E. thereof, at Brough Sowerby, they 
occur in considerable abundance. They do not, however, seem to 
make their appearance on the south side of the River Bela, a stream 
which runs into the Eden between Kirkby Stephen and Brough 
Sowerby. From the Bela the boundary of their sonthern distribu- 
tion runs H.N.E. to Stainmoor, and very few make their appear- 
ance on the south side of Argill beck, and none seem to occur along 
the line of the South Durham railway between Kirkby Stephen and 
the summit-level. They can be seen on the north side of Argill 
beck, a very fine block occurring near a small public-house, about 
half a mile N.W. from the farm called Pallard. 
Few, if any, of the blocks of Wastdale-Crag granite appear to 
have crossed the watershed which separates the Argill on the west 
from the Greta, a tributary to the Tees, on the east. This water- 
shed, at its lowest part, namely, the summit-level of the South 
Durham railway, is 1578 feet above the sea. 
A small stream, called Augill beck, drains the northern side of 
Stainmoor, and a watershed, about 1490 feet high, separates this 
stream from the source of the Black beck, a rivulet which flows 
into Balder beck, a stream draining the moory country on the east 
side of the Pennine chain, known as Hunderthwaite Moor. Be- 
tween the sources of the Augill and the Argill becks, Stainmoor 
rises to a height of more than 1500 feet above the sea-level; and 
this high ground, which has a N.W. and 8.E. extension for about 
four miles, forms the eastern boundary of the area of distribution 
between these two streams. 
There is abundant evidence, when we get north of this high por- 
tion of Stainmoor, that Wastdale-Crag granite blocks have found
