those on soil containing lime. Though the leaves are most 
affected, the shoots in their vicinity also participate. The 
disease is to trees what anzmia is to the human subject. 
It is due to a lack of iron in the soil, and the remedy is 
therefore obvious, although it must be inferred that the 
disease sometimes entirely baffles the cultivator. Apricots, 
Peaches, and many other frnits are affected, as well as 
Cucumbers and their allies, So far as Vines are concerned, 
French growers have found it advantageous to change their 
stocks, using those which are found growing wild upon 
similar soils.
