THE DICTIONARY OF GARDENING, 
Bordeaux Mixture—continued. 
have not been so widely appreciated as they deserve, 
considering its effectiveness, eise of application, and 
cheapness. The preparation consists of a’ solution of 
copper sulphate and gquicklime, with occasionally, to 
increase the adhesiveness, molasses or soft soap. Several 
strengths have been advocated to snit different plants 
and the foliage or fruit at various stages. In the young 
and tender stage of either foliage or frnit the solution 
should be weaker than when either is more advanced: 
On account, however, of the disfiguring effect it has upon 
fruits required for either market or the table, the fungi- 
cide should not be employed, say, within a month or six 
weeks of the time of its being required. In the case of 
ornamental plants it is better to use one of the clear 
fungicides, simply on account of the effect produced. 
See Fungicides. 
For general purposes, the best formula is: Copper 
sulphate, 6lb.; unslacked lime, 4lb.; water, 50gall. 
Almost equally good results have been obtained by 
further reducing the copper sulphate to 4lb. Professor 
Galloway, of the United States Department of Agriculture, 
gives simple but very minute directions for the prepara- 
tion of Bordeaux Mixture as follows: In a barrel place 
25gall. of water. Weigh out 6lb. of copper sulphate, 
then tie the same in a piece of coarse sacking, and suspend 
it just beneath the surface of the water. By tying the 
bag to a stick, laid across the barrel, no further attention 
need be given Im another vessel slack 4lb. of lime, 
taking care to ferm a paste free from grits or lumps; 
this is .best done by placing the lime in an ordinary 
water-pail, and adding at first, say, from 1 quart to 3 pints. 
When the lime begins to crack and crumble, and the 
water to disappear, another quart or more of water 
should be added, taking care that at no time the lime 
gets too dry. Towards last a considerable quantity of 
water will be required; but if added slowly by degrees, 
a perfectly smooth paste will result,if the lime used be 
of good quality. When the lime is slacked, add sufficient 
water to bring the whole up to 25gall. When the 
copper sulphate is entirely dissolved and the lime cool, 
the lime-milk and copper sulphate solution should be 
poured slowly together into a barrel holding 50gall., 
first thoroughly mixing the lime-milk. A final stirring 
for a few minutes with a broad wooden paddle completes 
the process. 
To determine whether the preparation is safe to apply 
to tender foliage, Professor Galloway recommends the 
following test: Insert the blade of a penknife in the 
mixture, allowing it to remain for at least one minute. If 
the polished steel assumes the colour of copper-plate, the 
mixture is unsafe, and more lime must be added. If, 
however, the blade remains unchanged, the mixture has 
been correctly prepared. 
If the Bordeaux Mixture cannot all be used after pre- 
paration, extra care will be necessary on its employment* 
subsequently to see that it is well stirred. After a time the 
useful constituents are precipitated, leaving a clear liquid 
of no value as a fungicide. Paris Green is sometimes added 
to the Bordeaux Mixture with a view to combining an 
insecticide with a fungicide.
