the lower part of the mountain. It occupies the very position, 
which, according to some authorities, should be most favourable 
for the deposition of minerals, but the most noteworthy feature 
connected with its mineral contents is extreme barrenness. It 
contains in some places abundance of quartz, with traces of copper 
throughout the greater part of its length, also here and there a little 
maganese and barytes. ‘The reason for this barrenness is not very 
apparent, the presence of quartz shows that there has been a certain 
amount of thermal action throughout the entire length of the vein, 
while at White Stones it has been remarkable for its intensity, and 
must have continued a great length of time. There are no igneous 
rocks between the vein and the higher ground, but it is very nearly, 
if not quite, in touch with the chiastolite slate on that side, both 
in Millbeck and Applethwaite Gills). The Trap dykes en Dodd 
cannot influence the vein, as they are on the wrong side. Short 
levels have been driven on the vein in Sandy Gill, above Mirehouse, 
and in Applethwaite Gill, small pits have also been sunk at various 
points on the back of the vein, but they did not open out anything 
that would warrant more extensive explorations. 
Some of the veins which join the Skiddaw vein at White Stones 
contain immense quantities of quartz, and one of them, in which a 
mine was opened a few years ago, yielded about one hundred and 
fifty tons of sulphate barytes, also some fine lumps of galena 
embedded in the barytes. 
The strongest of the veins which unite with the Skiddaw vein at 
White Stones, is one that takes a north-westerly course down Skill 
Beck Gill, to near Mirehouse, where it disappears beneath the 
thick alluvial soil. It contains abundance of quartz, and some 
galena; anda level has been driven on it, just above the road, near 
Mirehouse, but it does not appear to have yielded much ore. 
There are also lead veins on Cockup, in Dead Beck and Dash 
Beck Gills, and extensive excavations have been made in some 
of them, but they have not been remunerative. 
At Robin Hood there is a vein closely associated with the slender 
dyke of diorite at that place. It runs parallel with and close to
