Note—The Bradford Lead, } sheet 14 N.W. (illustrated by speci- 
mens 15, 23, 25, 26 and 30), appears to bẹ an extension of that occurring 
at the “Hard Hill” (see specimens 17 and 37), as it begins at about a 
similar height on the side of the gully opposite to where the other 
ceases. It commences as surfacing of angular quartz, cemented with 
granite detritus, and gradually deepens to about 80 feet near the south- 
west corner of the Bradford town reserve, where the deposit consists of 
alternating layers of white and variegated clay (kaolin) and granite 
detritus, resting on several feet of rounded quartz boulder drift. From 
the township reserve the lead extends across two small gullies, and 
reaches a third, beyond which it has not been traced. 
The minerals found in this lead comprise :— 
(1.) Smoky Quartz in great quantity. The faces of the crystals 
are seldom perfect, on account of their having been water- 
worn; sometimes they contain crystals of iron pyrites (cubes) 
and molybdenite.
