the conditions which favor its spread, a 
remedy 'can be much more successfully 
applied. The following brief rules, if 
followed carefully and conscientiously, 
will eliminate the disease from a grove, 
and in many cases save trees that other¬ 
wise would be lost. 
“i. Remove the soil from about the 
crown and the crown roots, at least as 
far back as any disease occurs. 
A very small, even an invisible amount, of 
virus is capable of starting the disease 
in a new place; consequently, any tools or 
implements used about a foot-rot tree 
should be thoroughly disinfected before 
being used on a healthy one. 
2. After the soil has been removed 
from the crown, cut out the diseased 
parts.The bark should be cut away 
as far as the disease occurs, which can 
be easily told by a yellowish or dark dis¬ 
coloration of the inner bark. As the dis¬ 
ease rarely penetrates into the wood, it 
will be sufficient to remove the bark. 
3. After the diseased part has all been 
cut out, apply an antiseptic wash. One 
of the most readily obtainable, and also 
one of the best, is crude carbolic acid— 
using one part of the acid to one part of 
water. .,. . . .When the disease makes its 
appearance early in the year, it may be 
necessary to repeat this operation a sec¬ 
ond time, or even more frequently. 
4. After the above remedy has been 
applied, .and no mew cases of foot-rot 
have been discovered for a period of two 
or three months, the following wash may 
be applied to the trunks of the trees and 
to such larger roots as are exposed: 
three parts of slaked lime, mixed with one 
part of flowers of sulphur. The ingre¬ 
dients may be easily mixed by passing 
them through a sieve, or by working 
them on the floor, very much as fertiliz¬ 
ers are mixed. After they are evenly 
mixed, place the powder in a tub or 
barrel, and add enough water to bring 
it to a consistency of paint.The 
trunks of the trees and all of the exposed 
roots should be given a thorough coating 
of this material. In groves where foot- 
rot is just starting and where the wounds 
are all very small, this wash alone will 
frequently be found sufficient. In groves 
where foot-rot occurs on a considerable 
percentage of the trees, it will be best to 
apply the wash to the trunks and larger 
roots of all the trees—those that are not 
affected as well as the diseased ones.” 
GUMMING. 
A disease known as gumming of cit¬ 
rus trees is becoming a serious trouble in 
many localities of the Stace. It has brok¬ 
en out in some groves to an alarming ex¬ 
tent. 
Description— The gumming areas 
are usually at considerable distances 
from the ground on the trunk and larger 
limbs. This point of difference distin¬ 
guishes the diseases from the foot-rot. 
The bark cracks, and gum oozes out in 
large quantities. When the bark just 
adjoining the affected area is cut off, it 
is seen to be yellowish inside, and the 
bark tissue has a sour odor as if fermen¬ 
tation had set in. The diseased areas as 
they enlarge may reach one-half to three- 
quarters of the way around a large limb. 
In some cases the limb or trunk is girdled. 
Where the case is not too severe, new 
bark tissue is formed underneath the old, 
and the surface of the diseased area be¬ 
comes characterized by ridges, warts and
