A system so inelastic, and so deadening to all initiative, could have but one result.
Rubber slowly absorbs oxygen when exposed to air and light, the absorption of oxygen being accompanied by a gradual change in the characteristic properties of rubber, and ultimately to the production of a hard, inelastic, brittle substance containing oxygen.
It not only secured an immediate market for government bonds, but it also provided a permanent uniform national currency, which, though inelastic, is absolutely stable.
Water is comparatively very heavy, inelastic and incompressible; air, on the other hand, is comparatively very light, elastic and compressible.
