represent the main sulphur channel in the supposed dead 
ground between East and West Cronebane. If this supposition 
is correct, hereabouts the main sulphur lode is heaved south ; 
but nothing positive can be stated until the Blue Burrows lode 
is proved in depth. Its gossan and gossan ore are very similar 
to those inthe Magpie Mine. JII. Discovery lode—tThis possibly 
is part of the Blue Burrow lode as just mentioned. IV. Morgan's 
lode.—There are “old men’s” workings on this lode, but very 
little is known about it at present, except that it is a nearly per- 
pendicular E. and W. vein. It is said to have been worked for 
copper ore before Weaver’s time. V. Yellow Bottoms lode— 
This was a massive shoot of chalcopyrite which continued in 
depth for 53 fms., with an average breadth of 1:5 fms., and 
dipped south at 70°. Six fms. west of Yellow Bottoms shaft it is 
crossed by a fault bearing N. 50° E., which displaces the lode its 
own breadth. This lode seems to die out east and west in the 
country rock. 
The mineral channel in which these five lodes occur is separated 
from that of the Magpie or East Cronebane by a N. 45° W. fault, 
which displaces the rocks of the country to the north and south. 
Formerly it was supposed that the mineral channel of the Yellow 
Bottoms contained a sulphur lode, which was a continuation 
westward of the main sulphur lode of the Magpie, next to be 
described. Recent explorations, however, have shown that such 
is not the case, but that the latter lode towards the W. splits at 
the Quaker’s shaft, and that both branches in a short distance 
become unprofitable, and eventually die out in the hard killas of 
the faulty ground ; so that no connexion whatever can be traced 
between this lode and those in the Yellow Bottoms. The latter 
have E. and W. bearings, while the Magpie has a bearing of N. 
60° E. 
East Cronebane and Connary Mines. 
East Cronebane ordinarily includes the Magpie Mine and ad- 
joining veins, also the Yellow Bottoms lodes ; the latter, however, 
we have found more convenient to describe in connexion with the 
_ “ Dead Ground,” with which they are more immediately connected, 
Magpie Mine—Here the north or main lode, as just now 
stated, branches going westward from the Quaker’s shaft north-
