The true test of the industrial civilization of a people is the extent to which every scrap and grain of its resources are utilized. The motto of a prosperous nation is: "Gather up the fragments that nothing be lost."
That the last few years have seen such an increase in the production of wealth as has never been known before in the history of the world is not to be wondered at when it is realized that in every department of industry those things that had been previously thrown away have become a source of revenue, and, in some cases, the by-product has become of more value than the original product itself.
The recovery of wealth from waste is the distinguishing mark of the age, because this is the age of industrial civilization. If the increase in the production of wealth is greater and more rapid than it has ever been since man first landed on this earth, without either a penny or a pocket to put the penny in, it is due to the general extension of methods that have been in use ever since he began to try to pick a living out of the clinched fist of dour old Mother Nature.
The delicate perfumes of flowers that otherwise would vanish in a day are trapped in lard, and then snared again from the lard by alcohol. The crusted argols that gather on the inside of the vats where wine ferments are utilized to make the cream of tartar for our biscuits.
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.
