the geological position of the deposits. It is a remarkable fact, 
also, that while barite is entirely missing in the southwestern 
region, this mineral is, in this central region, a nearly constant asso- 
ciate of the galenite in the Carboniferous as well as in the Silu- 
rian rocks. These facts suggest the idea, as Mr. Schmidt ob- 
serves, that the occurrence of lead ore, with its associates, is not 
e under similar conditions at the time of deposition. If this sug- 
gestion is correct, it would throw the origin of all the galenite of

e Atlas accompanying the Report contains geological maps of 
Cedar, Barton, Vernon, Bates, Howard, Madison, Jasper and New- 
ton Counties, with uncolored maps of the lead districts, and three 
sheets of parallelized sections of the Coal-measures. These last 
seem to us objectionable, in that they give but little information, 
while involving great expense. The field-notes thus published

by R. Broves Smyru, Secretary for Mines for the Colony, with 
additional reports on the mineral resources of Ballarat, by R. B 
Murray, and on certain Coal-fields; and the other, Decade I, op
