Tin Pans for Complexions.

The bloom of health that glows upon the cheeks of the ladies of the
chorus may be traced to the tin pans and cups that jingle on the
rag-collector's wagon. These homely and prosaic vessels are made of plates
of iron, coated, all too thinly in these degenerate days, with tin.

These iron plates have to be "pickled," as the trade phrase goes. All the
rust and other substances than the clean iron have to be washed off with
acids and water. The pickling liquor is not emptied out as slops by any
means. There is a finely divided iron rust floating in it, and when the
water is removed by evaporating it, the residue is Venetian red and iron
pigment that, made up as rouge, can counterfeit the ruddy blood that
courses so near the surface of the satin skin of youth.

It is almost a personal triumph to us to know that the broken bits of rock
from the quarry, unfit to use as building material, are turned into
crushed stone, for which there is so large a demand, thanks to the
increasing popularity of concrete, and that its revenues pay the operating
expenses of the quarry, and make the price got from building stone so much
clear money.

Illuminating-gas has to be washed and scrubbed anyhow before it can be
introduced into our houses. The household ammonia with which the kitchen
sink is kept so sweet is taken by the thousand tons from the scrub-water
of the gas-house and the furnace-gas of iron-works.

Only the Pig's Squeal Gets Away.

Meat packers will tell you that nowadays they save everything but the
pig's last dying squeal. Naturally, the hides and skins of the animals
slaughtered are worth saving. The tips of cows' horns are used for the
mouthpieces of pipes; the horns themselves are split and pressed flat, and
combs, the backs of brushes, and large buttons are made of them. What bits
and splinters are too small to be worked up go for fertilizer.

Hoofs are sorted by colors. The white ones go to Japan, there to be made
up into ornaments of artistic merit. We haven't got that far along
ourselves. The striped ones stay here to be made up into buttons. The
black ones are utilized in the manufacture of cyanide of potash, by which
gold is extracted from low-grade ores it formerly did not pay to work.

The bones in the feet of cattle bear up a great weight, so they are hard
and take a high polish. They can be used instead of ivory, which is
gett
