is really not a sulphur solution, but a solution of sodium sul¬ 
phide, but I hope to work on it further and give the members 
of the Society the advantage of whatever discoveries I may 
make. 
There are a few other points I wish to report on relating to 
the work in progress at the Sub-Tropical Laboratory, on the 
diseases of citrus fruits. 
BLIGHT. 
First—In regard to the orange blight: I have been before 
the Society for three years telling a continued story about 
blight and I am sorry to say that the discussion will have to 
be continued longer. Prof. Webber and myself have been ex¬ 
perimenting at the Sub-Tropical Laboratory at Eustis in a 
number ol different ways, but we are surprised at the extreme 
slowness in which these experiments show results. Having 
made for two years careful examination of the blight of the 
orange, we have been unable as yet to find any cause which 
could produce this disease, but every experiment we make 
strengthens the view that the disease is contagious. It has 
been found almost uniformly that extirpation of the first few 
cases in the grove is the best way to prevent the spread of 
the malady. We have in progress experiments to prove 
whether this disease is contagious. The blight very often 
spreads from adjacent trees. It is still unsettled whether the 
disease can be conveyed from the top of one tree to another. 
We have taken buds from blighted trees and inserted these 
buds into healthy trees—into the top and into the roots and 
we will watch with interest the progress ot this experiment. 
We will report on all of these experiments later. I would 
urge all those who have only a few affected trees to take them 
out and burn them. There is little doubt in my mind but 
that trees contract blight from one another. To growers who 
have large numbers of trees affected, such a measure might 
seem to be severe and I would suggest to such that some of 
the more vigorous trees might be grafted to quick bearing 
varieties. This, however, I would only urge in cases of long 
standing. Those trees that are burned should be burned on 
the spot and not dragged through the grove. 
Mr. Peck —Over what region of the state does blight ex¬ 
tend ? 
Prof. Swingle—I have seen it all over the state. 
FOOT ROT. 
Upon the foot rot we have done so far only a limited 
amount of work, but we have at last found a region where we
