Haworth. | Geography of Lead and Zine Ores. A5 
side of section 8, the Gracie Clark mine has produced a fair 
amount of ore. 
The most important outlying mining camp is about five 
miles north of Galena on the west side of Spring river, in 
sectins 23 and 24, where the property of the Badger Mining 
and Milling Company is located. A prosperous mine was 
opened up in 1898, which for years produced a surprisingly 
large amount of high-grade zinc ore. More recently, 1902, 
quite a-remarkable ore body was found. Opposite this, on 
the east side of Spring river near the state line, zinc ore was 
found almost immediately at the surface. 
Galena’s Position wn the Joplin Area. 
Galena is situated to the southwest from Joplin and Webb 
City, the mining centers of the Joplin area. On the United 
States topographic map of the Joplin area this is very well 
illustrated. A straight line drawn from Galena to Carthage 
has a position almost exactly two miles east to one mile 
north, which very closely corresponds to the elliptical pe- 
riphery of the Ozark dome in that place. Could we draw a 
curved line through Albia, Carl Junction, Pitcherville and 
Baxter Springs it would parallel almost exactly the ellip- 
tical curves representing the northwest slope of the Ozark 
dome. These points named represent respectively the north- 
westernmost outlying mines of the entire region. If, now, 
we pass to the southeast a distance of ten miles, and draw 
- another curved line parallel to the first, it will go just be- 
yond the outlying mining camps of Duenweg and Redding’s 
mill; or, in other words, this gently curved zone about ten 
miles in width will include more than eighty per cent. of the 
productive area of the entire Joplin district. Should we ex- 
tend the zone a little farther to the northeast beyond Car- 
thage, having it bear southward in conformity with the dome 
curve, again it would include almost eighty per cent. of the 
entire productive region outside that just given. ‘This de- 
scription does not include the northern Arkansas-southern 
Missouri fields which le to the south of Springfield. Should 
we extend a similar curved line to the south and then south- 
east around the southern border of the Ozark dome, we would
