done, but they consented to our doing it 
for them. 
Now any grower who has ever spray¬ 
ed for white fly, knows that he has got 
off easy, if he has not spent more than 
$135 on ten acres, and still he knows 
that he has not killed them all and that 
enough are left to keep him working the 
next season. If he could only be sure 
that he had stamped them out, he would 
not mind that expense. 
We have not found a live fly, so far, 
this spring, in or around DeLand, and 
all it cost us, was $158.80 to do the 
work. 
We consider it a good investment, even 
if the flies get in next year, for all our 
groves are free this year anyway. 
From the experience we have had I 
feel sure the fly can be stamped out of 
^drnost any section of the State, if the 
growers will only go at it in earnest, and 
be willing to lose all the leaves, where- 
ever there are any signs of the fly found. 
By doing this work as late as possible, 
in the spring before the fly begins its 
general hatch, or the trees to bloom, the 
work can be done with the least expense, 
and it need not diminish the crop any 
more than the fly itself would do, if as 
much. 
I wish to say right here that our com¬ 
mittee was greatly helped by two visits 
from Prof. Rolfs, he encouraged us to 
believe that we could make a success of 
it, and he helped to make the skeptical 
growers willing to allow us to take the 
leaves from their trees. 
Our society was also greatly helped 
by a talk he gave us on insects, and dis¬ 
eases, and I am sure that if the growers 
in the different localities of. the State, 
would organize as we have done, and then 
when a difficult problem comes up, invite 
Prof. Rolfs to pay them a visit, they 
would soon find that his talks would save 
them in the expense of working their 
groves, much more than the society would 
cost them. So far our society has cost 
none of its members more than seven dol¬ 
lars apiece. 
One lesson we have learned at DeLand, 
that is if you fear the white fly watch 
your jessamine bushes as the fly will ap¬ 
pear on the Cape Jessamine first and if 
you want to delay their coming destroy 
all such bushes in your neighborhood. 
The fly will spread faster from one 
jessamine bush to another than from one 
orange tree to another. 
In many cases we found larva on Jessa¬ 
mine bushes and no sign at all on orange 
trees near by, but if there were many of 
the larva on the jessamine bushes we de¬ 
foliated the orange trees as a precaution. 
To overcome thieving, we allow any 
member of the society who wishes to do 
so, to post a notice of $25 reward offered 
by the society for evidence that will 
convict any one, other than a child, for 
stealing fruit, and the society does the 
prosecuting, which makes it easier to pun¬ 
ish a thief than if an individual had it to 
do.
