[Enclosure in No. 1.] 
My Lor Paris, 21 June 1890. 
im lower Vivian asks for information dd statisties relative to 
the use of. sulphate of copper for dressing vines in France, a 
that there must be some exaggeration in figures which Sir Hysey 
Vivian quotes. 
According to the returns of the Custom House the quantities of 
esc of copper entered for home consumption in France since 1 
have been as follows :— n 
1887 kilos 7,736-746 
188 
»  8,818:922. 
1889 V 18, ,924-001 
During the first five months of the present year the quantity imported 
has been as much as kilos br 10 or double the amount imported 
during the same period y 
But sulphate of copper is not used for the purpose of killing we 
The prime remedy for that is sulfuret of carbon ; sulphate of 
ood for dressing vines threatened with or suffering from mildew or say 
other cryptoganic disease. à 
Hs is mixed as a powder with common lime and blown with 
4 zators " on arde the vine leaves. The name of the mixture is. 
expected. But the expense of cage is very great in rainy or 
windy seasons, as the bouillie must be renewed hai ver the dee has | 
been vines. 
It is difficult to state with any correctness why the imports Mn sulphate 
of copper have become so large duri Bo the first half of the present year. 
Price has risen with the aeaii demand, and yet there is no mildew 
at present visible in French vineyards. 
Iam told that the phenomena which are observable at this mene e 
are only to be explained by a large speculative business in Qu 
copper, which is an article that does not lose wg from ere and 
which may suddenly be required in large quan
