Notes. (Artificial alizarine vs. madder)

Popular Science, heinäkuu 1883

The agricultural interests of the south of France have been nearly ruined by the substitution of the artificial alizarine for madder in dyeing, the silk-worm disease, and the phylloxera. The cultivation of madder will have to be given up, for it can not again be made profitable. The disasters wrought by the silk-worm disease and the phylloxera, now that remedies have been discovered, may be repaired in time. To expedite the recovery of the depressed agriculture, an extensive scheme of irrigation has been arranged, by which water will be drawn from the river Rhône in canals, and distributed to all the country within reach.
