The Consolidated Iron Works Co. of 
Kansas City, Kan., has an annual output 
of 8,000 tons. 
A week's output of the mines at Aurora 
Mo., amounted to ^$12,560. There was 95 
tons of lead, 1071^ tons of zinc, and 306 
tons of silicate. One mine alone, the Big 
Bonanza producing GO tons of zinc in 
four days, 
Pennsylvania's "smoky city" has quite 
an active rival in Pittsburg, Kansas. Her 
smelter output for one week being* nearly 
275 tons and tlie coal output for the same 
week was 18,400 tons or 920 cars.-D.H.T.

An exchange says : "Don't be a clam. 
If you've got to be anything- of the kind, 
be a mud turtle. There you may have 
some snap to you." If you appreciate 
a good thing you'll snap at the oppor-

The above cut is figured half tlie 
natural size of a surfacj found near 
Quincy, HI., of which Mr. C. A. Thomp- 
son writes: "The stone is porphyritic 
diabase, the large spots are changed 
feldspar of a cream color; other colors 
are dark brown and greenish and I think 
it would puzzle a mineralogist to find a 
duplicate of the same color in this rare 
beautiful stone. I think nothing of the 
kind has ever been heretofore found. I 
send outlines for remarks". This is a 
relic of fetichism of one of the American 
tribes ; in the manufacture of these articles 
the coloi- of the stone and animal repre- 
sented was selected according to the 
particular destiny in which the figure 
was supposed to possess unknown powers. 
The form is not especially rare. * [e. b. 
Taxidermists and collectors the world 
over cjui rejoice at the prospects of soon 
obtaining a gun that islightjoccupjang so 
little space that it may be carried in the 
pocket, tired with no more noise than 
accompanies the discharge of a soda 
fountain, smokeless, odorless, with no 
recoil, no heat and so constructed that by 
turning a screw the bullet may be ex- 
pelled with any degree of force desired. 
It is not eftected by heat or dampness 
and the explosive is so cheap that 125 
bullets can be fired at a cost of one cent
