(Scilla nutans), Violets (Viola sylvatica), Wild Strawberries 
(Fragaria vesca), and Bilberry (Vaccinium myvrtillus.) Another 
drive took the party back to Tamworth, where Miss Jasper,

the usual] votes of thanks, the Burton contingent took the 
train homeward, reaching Burton about 7-30. 
CASTLETON, JUNE 22ND. 
Leadey: J. G. WELLs. 
The party, numbering 16, arrived at Hope Station (on the 
Dore and Chinley line) shortly after mid-day, and drove 
thence to the ‘‘ Blue John” mine, staying at Castleton for 
lunch on the way. After inspecting the slopes of Mam Tor, 
the descent was made of the mine, the principal features of 
which are the curious natural caverns which were encoun- 
tered during the mining operations. The occurrence 7m situ 
of the mineral ‘‘ Blue John,” as well as many other geolog- 
ical points of interest, was pointed out by the guide, to 
whom the party are indebted for his courtesy. Leaving the 
mine, the party walked to the Windy Knoll Quarry, where 
the Leader pointed out the occurrence of Bitumen, in both 
its elastic and hard forms, Fluor Spar, ‘Blue John,” and 
other minerals. Passing down the narrow pass of the Win- 
nats, the Speedwell Mine was reached and descended, the 
party proceeding by boat through the old workings of the 
mine, and inspecting the ‘‘Grand Cavern,’’ an enormous 
natural cavern discovered during the unsuccessful mining 
operations for lead. After tea, which was served at the 
*“Nag’s Head,” the party visited the entrance of the Peak 
Cavern, with its fine natural archway, beneath which a 
colony of rope spinners has established itself; and also Peak 
or Peveril Castle, a well-nigh impregnable stronghold made 
famous by Sir Walter Scott in his ‘ Peveril of the Peak.” 
From Castleton the party drove to Hope Station for the 
return journey.
