water and fungus we sprayed on the 
fruit. 
Mr. Dade: At Orange City I com¬ 
menced the use of the fungus. I kept 
at it with the fungus. This is the third 
year, and we have had a heavy crop, and 
I think the fly has been reduced. I be¬ 
lieve if we follow it with the insecticide, 
it will break the hold of the smut, so that 
the orange cleans very readily. 
Dr. Berger: I like the tone of Mr. 
Stevens’ paper; he covers the ground 
very nicely, and it is an interesting ex¬ 
perience. 
I would like to mention the Winter Ha¬ 
ven Protective League. They have 
fought the whitefly with spraying solu¬ 
tions for six years very successfully, as 
nearly as I can make out. 
Mr. Stewart: The whitefly is like 
hog cholera; when it gets in there it is 
going to kill off one crop of hogs before 
you get rid of it. The fungus in my tan¬ 
gerine grove cleaned it up as though you 
had gone through it with a fine-tooth 
comb. Some of my neighbors were 
spraying for the whitefly^ and the only 
process in the world my trees were going 
through with was a cleaning up by the 
fungus. The fungus took care of it 
as well as it was possible to be done. I 
have given the fungus no assistance, ex¬ 
cept to furnish plenty of it. There is 
no doubt but that sprays have often got¬ 
ten credit for what the fungus itself has 
done. The fungus will do the work if 
you will let it alone. t 
Mr. Glass: I am here representing a 
grove that has never been sprayed at all, 
because of its peculiar extent and condi¬ 
tion. We have never sprayed at all; the 
fungus is doing the work. There are 
oranges and grapefruit picked from that 
grove this year absolutely perfect, where 
four or five years ago it was almost im¬ 
possible to find a fruit not infected by 
the whitefly. I believe the fungus is 
doing the work. 
I have seen a number of leaves which 
Dr. Berger picked at random through the 
grove. You need not be afraid of the 
whitefly if your grove is covered with 
the fungus, as these leaves indicate. It 
is a peculiar fact that in the heart of the 
tree, sometimes the most beautiful or¬ 
anges have been picked, perfect in ap¬ 
pearance, color, 'size, and shape; what 
you would call a fancy. There is a sug¬ 
gestion, however^ made by a gentleman— 
I have forgotten his name, he is in 
charge of the convict camps in that dis¬ 
trict—Mr. Gillette can tell me. 
Mr. Gillette: I am not very familiar 
with the convict camps. (Laughter.) 
Mr. Glass: He showed me some trees 
he had sprayed with nothing in the 
world but flour and hot water, making 
a kind of paste, and diluted it and spray¬ 
ed it on the trees. The whitefly soot was 
absolutely removed from the surface of 
the leaves. He told me he had been at 
Orando and Mr. Yothers had talked to 
him about it. It is possible a little tiny 
bit of carbolic acid might be added. This 
may or may not be of use to you gentle¬ 
men. The gentleman who told me about 
it said he had been doing this for twenty 
years. 
Mr. Dade: My observation is that 
the smut remains where you use the fun¬ 
gus only, and you have the same trouble 
with that, although maybe you are get-
