 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 Temple 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 5-1/2 miles north from Cliburn ; and this is the most northern limit which has been yet recognized of the occurrence of these blocks. Long Wathby is four miles N.E. of Penrith. 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 S. and S.W. of Penrith their occurrence is unknown.

From the south side of Wastdale Crag, the granite blocks have taken a S.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 2-1/2 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 southern distribution runs E.N.E. to Stainmoor, and very few make their appearance 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 Palliard.

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 1378 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. Between 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 S.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 portion of Stainmoor, that Wastdale-Crag granite blocks have found
