SEVENTH ANNUAL MEETING OF THE 
their oranges were worthless. One of them, Mr. Hoyt, gave 
me a sample of his oranges, and there was no acid in them at 
all. 1 take the position that bi-sulphate of soda will neutral¬ 
ize the acid in the fruit. 
Edward Winter— The spreading of diseases and insects- 
of the citrus is a matter of such serious importance that it 
seems to me we should make some effort to prevent it. I have 
recently seen nursery stock badly infested, if we can take 
steps to prevent such pests being disseminated I think we 
should do it. 
Mr. Bacon —It cannot be done. It is impracticable. These- 
troubles are spread in many ways we cannot reach or control. 
Take the smut for instance; it thrives anywhere, it will even- 
grow on potatoes. Five years ago I discovered it < n the 
palmetto trees about my place. It spread quite rapidly, but 
for a year I did not see any on my bearing orange trees,. 
Then I began to see a little on my large trees, and the third 
year 1 began to get worried. The tiees bloomed well, but 
dropped their fruit, dead limbs began to appear, a great 
many leaves dropped off; in the fall you coul 1 see through 
Mandarin trees that formerly you could not thrust your arm 
into. The fourth year I got a spraying outfit and went to 1 
work. I used a lime and sulphur solution, the recipe can be 
obtained from the Farmer and Fruit Grower. 
Mr. Duncan —A good deal of the smut found upon orange 
and other trees is not produced by, or rather does not follow 
the White fly. We had smut on orange trees before we ever 
heard of the White fly. This smut is easily destroyed by the 
rosin wash. 
G. P. Healy —Some time since I supposed I had the White 
fly. I was discouraged. The grove seemed in a bad fix, and 
the fruit was getting very black. Ab >ut that time Prof. 
Webber arrived. We examined the trees and in my case the 
sooty mould was found to be following the wax srale instead 
of the White fly. It was a bad case, but I used Thrip juice 
and cleaned almost all the smut off the trees. The owner of 
one grove we visited while Prof. Webber was at my place 
said he had had the smut (but not following the White fly) 
and had gotten rid of it by the use of tobacco juice. At 
another place we found the sooty mould following the White 
fly* and the owner assured us that he had not succeeded in 
finding anything that was effective in destroying it. 
Prof. Webber —In reg trd to tobacco juice: The trees 
Maj. Healy and I saw did seem to be effected by the tobacco 
juice, but to what extent it had been effective as a remedy for 
the sooty mould could not be determined. I tried tobacco-
