From that time it fell, and it was very cheap during the whole of
1869 and 1870. The effect of this cheapness is great in every
department of industry. The working classes, having cheaper food,
need to spend so much less on that food, and have more to spend on
other things. In consequence, there is a gentle augmentation of
demand through almost all departments of trade. And this almost
always causes a great augmentation in what may be called the
instrumental trades--that is, in the trades which deal in machines and
instruments used in many branches of commerce, and in the materials
for such. Take, for instance, the iron trade--

In the year 1869 we exported 2,568,000 tons
" 1870 " 2,716,000 tons
5,284,000 tons
" 1867 " 1,881,000 tons
