of their trees by using Bordeaux mixture made by means of the 
ferrocyanide test where the test was not properly followed this 
does not prove the test unreliable. Injury from spraying during 
the past season resulted where the ferrocaynide test was not used 
as well as where it was used, so that the conclusion that all injury 
to sprayed apples and pears resulted from relying on the ferro- 
cyanide test cannot besustained. Whether the injury from spray- 
ing when this test was followed was greater or less than where 
it was not used has not yet been shown and no exactly determined 
data on the subject have yet been published.
