Report of Committee on Diseases, Insects and 
Method of Control. 
[There was no regular report made by 
any member of the committee, but the 
question was opened for discussion, and 
this proved very interesting. The fol¬ 
lowing is as full a report as the stenog¬ 
rapher was able to make.—Sec.] 
Mr. Hart.—Mr. President, I regret to 
say that I have been unable to make any 
report owing to the fact that I have been 
in a dark room for some weeks, unable to 
read or write and have had to depend 
upon some one else to do my writing for 
me. After the President had notified me 
I was on this committee I communicated 
with other members telling them of my 
disability and urging them to attend to 
the work necessary to a good report. 
Mr. Hubbard.—I have no formal re¬ 
port on this subject. I have had no ex¬ 
perience with the white fly, not even 
like our friend Mr. Hart. I have a small 
joke at Mr. Hart’s expense. One of our 
neighbors sent him a specimen and asked 
if it was the white fly, he also wrote Mr. 
Hart, but Mr. Hart was- so afraid 
of the white fly that he immediately burn¬ 
ed it without examination. I do not 
believe this gentleman had the white fly, 
but he did have the white wax scale. 
The red fungus is now attacking this 
scale and I think he will soon be rid of 
it. 
T practically do no spraying. In cases 
of small trees I use a small atomizer, 
using pure kerosense and treating them 
on a warm, dry day, putting it on care¬ 
fully. The kerosene will evaporate in 
about an hour and one application will 
remove most of the scale and will not 
hurt the foliage. Kerosene has practi¬ 
cally the same chemical composition as 
turpentine and the essential oil of the 
orange, so that when it evaporates it 
has very little effect on the tree. If you 
should saturate the tree with the kero¬ 
sene, of course it might do some damage. 
(Question.) Have you used whale oil 
soap? 
Mr. Hubbard.—I used to do this, but 
am now depending on Lady bugs and 
fungus. Orange trees may have some 
scale the first season, but the next year the 
lady bug and fungus will clean them out 
pretty thoroughly. If a man sprays for 
red spider etc., he kills the fungus and 
has to keep up the spraying continually. 
Maj. Healy.—Mr Waite seems to be 
the only one who has had any experience 
with the white fly. 
Mr. Waite.—One of the oldest groves 
we have, contains 600 large trees, so 
large we cannot get in between them to 
spray. This grove has been infested with 
the fly for ten or fifteen years. The fungi 
is very abundant, also about one hundred 
trees are inhabited by the snail, specimens 
of which I have brought with me. We 
commenced picking this crop of 4000 
boxes during Christmas week and finish¬ 
ed about the twentieth of January we
