inadvisable to use the Bordeaux mixture, because of the danger of 
discoloring the fruit. 
It is understood, of course, that the Bordeaux mixture is 
applied to the young* canes only, and not to the fruiting canes, since 
it is the former that we wish to protect from possible infection from 
the old diseased canes. In spraying raspberries, as well as other 
things, it must be remembered that thoroughness is what counts; 
g*reat care should be exercised to see that every part of the cane, 
particularly the portion next to the ground, is entirely covered with 
the spray material each time the operation is carried on. In place 
of attempting to spray both sides of the row and between the 
bushes at the same time, requiring the operator to' reach around 
them, we have found it more practical and more expeditious to 
drive between the rows, to treat the inside of the rows next to us 
and part way between the bushes, and then to drive down the next 
middle and finish the other side of the former row and one side of 
a new row. 
The old fruiting canes should be removed and burned as soon 
as the berries have been gathered in order to prevent any possible 
infection of the new canes. 
Preparation of 'Bordeaux Mixture. 
We have found a barrel spraying outfit adequate for this work 
and entirely satisfactory. The pump employed should be capable 
of giving at least 50 pounds pressure, and can be purchased for 
from ten to twelve dollars, exclusive of the barrel. 
For preparing the Bordeaux mixture, it will be found con¬ 
venient to have two half barrels with a capacity of about 30 gallons 
each, made by sawing in two a 60 gallon barrel. Three or four 
wooden candy pails should also be provided. 
For every 50 gallons of Bordeaux mixture, dissolve 3 pounds 
of copper sulphate in two or three gallons of boiling water in one 
of the wooden pails, and slake the corresponding amount of lime. 
2 pounds, in another, using just enought water to keep the lime 
from burning, and to give a thick, smooth paste, of about the con¬ 
sistency of white-coat. Two pounds of rosin fish oil soap are dis¬ 
solved in about 2 gallons of water. The solution of copper sul¬ 
phate is next poured into one of the half barrels, and enough water 
added to make 25 gallons; the slaked lime is washed into the other 
half barrel, with enough water added to make 23 gallons; the 2 
gallons of water on the soap will make the 50 gallons of water 
•shown in the formula 3-2-50. The diluted solution of copper 
sulphate and lime are now ready to be mixed. No better method 
has been devised for doing this on a small scale than that shown in
