UNWASTED WASTE.

An American professor on the West Coast has been urging that farm waste will be the ultimate source of the world's wealth. In The chemical conversion of farm waste," he sees the manufacture of the future. Well, this green and inexpensive powder, which a most ingenious, though simple, machine was spraying on to Lord Iveagh's straw ricks, repre- sents one practical immediate fulfilment of the professor's prophecy. Adco is used at present more by small gardeners than by big farmers. It will turn any grass, leaves, or her- baceous stalks into the very best manure. The rubbish

from Lord Iveagh's own beautiful gardens was being so converted. But the scale may be big as well as small. The day will probably come when it will save the wasteful destrue- tion of millions of tons of grain, straw, cocoanut fibre and other rubbish in many quarters of the world.
