the report. During the summer of 1903 the writer carefully 
examined the dump pile where a well had been sunk in the 
extreme southwest corner of Linn county and succeeded in 
finding quite a number of little crystals of lead ore and zinc 
ore thrown out with the shale while digging the well. 
ANDERSON COUNTY. 
Lead ore and zinc ore have been reported from many dif- 
ferent places in Anderson county. During the summer of 
1904 lead ore was discovered in fissures in the limestone both 
northwest and west of Garnett, and a company was organ- 
ized which is now mining, or prospecting, with indifferent 
SUCCESS. 
OSAGE COUNTY. 
From two to five years ago a number of different people in 
the northeast corner of Osage county discovered so much zinc 
ore that they became mildly excited over the prospect of 
opening up a new mining district. Numerous specimens of 
this material were examined and are now in the museum of 
the State University. Zinc ore seemed to be much more 
abundant than lead ore. Here, asin Leavenworth county, 
apparently its most favored place of occurrence was fissures in 
calcareous concretions embedded in the shale. Such concre- 
tions are quite numerous in many places throughout the Coal 
Measures of Kansas and very generally carry more or less 
zinc blende. 
COFFEY COUNTY. 
In the northern part of Coffey county in a number of places 
good-sized crystals of zinc blende have been found in the 
shale almost immediately at the surface. During the autumn 
of 1902 Mr. John Bennett, who has done so much work on 
the Kansas Geological Survey, brought in a fair-sized bunch 
of blende crystals that he picked up by the roadside with al- 
most no digging, the crystals occurring in the shale at a 
place where erosion had recently removed the soil and debris. 
Some discoveries have been made in other places in the same 
county, and also in a number of adjoining counties.
