Measures of prevention may accord- 
ingly be divided into such as deal with 
the— 
1. Distinction of cuttings; 
2. Winter treatment of pruned stocks ; 
3. Summer treatment of growing 
plants; and 
4. Choice in planting of little suscep- 
tible varieties. ~ 
1.— TREATMENT oF Currinas. 
(a) These, when planting is contem- 
plated, should be procured from a place 
where biack spot disease or Anthracnose 
has not occurred during the past season, 
or at least from vines that have not been 
the object of its attack. 
(b) If when raceived they exhibit the 
peculiar brand-like marks that are char- 
acteristic of the presence of the disease, 
they should not be used for planting, but 
rather be burnt forthwith ; and 
(c) In other cases they should be dis 
infected to destroy germs possibly 
adherentto them This may be accom- 
plished by steeping them in a carbolic 
acid bath (2 oz, in 4 gallons—1 kerosene 
tin full— of water) or in a potassium 
sulphide one (4 oz in the same quantity 
of water) for from 10 to 15 minutes. In 
the latter case, a wooden ves3el—éask, for 
instance, should be employed. 
2.— WINTER TREATMENT or VINE Srocks. 
This treatment should take place after 
the vines have been proyed and whilst 
the buds are quite dormant, no growth as 
yet being evident. It should consist in 
the following procedures— 
(a) The pruning to be removed and 
burned, and the resulting ashes restored 
to the plants 
(b) The stems to be rubbed by the 
hand, enclosed in a coarse glove made of 
bagging or some such substance so as to 
remove all loose bark.. Some purveyors 
of gardeners’ requisites stock a special 
glove for this purpose. 
(c) The whole of the parts above 
ground to be painted or mopped with’ 
commercial sulphuric acid and water of 10 
percent strength, ie., with a mixture 
composed of 1b of acid in 161b (1 gallon) 
of water. This dressing must be made 
and conveyed in a wooden, earthenware 
or enamelled vessel, since metal recep- 
tacles would be corrodediby it unless 
‘ 
parts of the States at lowest 
coated with anti-acid paint. With re- 
gard to adjusting the proportion of acid 
equired for every gallon of water it has 
been pointed out that as a reputed quart 
wine or whisky bottle holds 1-6th gallon, 
i,e., 3lb—of acid, a third of its contents 
will be the measure of acid required for 
every gallon of water. 
In mixing the acid and water, the 
former must be graduallj added to the 
water, and not the water to it, otherwise 
spurting with consequent injury to the 
person may result. : 
The application may be made with 
rather a large sized brush, composed of 
bristles of horse hair, or with a rag mop, 
the handle in each case being fairly long 
Insomuch as this acid application is des- 
tructive to clothing if shed upon it, and 
is also rough on the skin, care should be 
taken to avoid splashing, and the operator 
should be clad in old garments whose in- 
jury is not a consideation. 
In France a special knpsack spray 
pump is employed for this, and an equally 
corrosive winter dressiug, 
Going over in the manner described 
one or two vines of average dimensions 
with simple water will afford an insight 
into the quantity of sulphuric acid re- 
quired for treating an entire vineyard or 
any definite portion thereof. 
When first making known to Australian 
vignerons twenty years since the nature, 
cause, aud mode of treatment of Grape 
Vine Black Spot Disease, the writer 
recommended the use of a strong acid 
sulphate of iron solution ia lieu of s 1- 
phuric acid and water for this winter 
application. This is still the most favored 
one in France, and is composed of sul- 
phate ofiron, 50 parts; water, 100 parts 
and concentrated sulphuric acid, 1 part, 
Unless, however the climate bea moist 
one, some danger to the vine may resuit 
from its application.
