Discuss results of two experiments with small quantities of soil treated with copper sul¬ 
phate showing the sulphate to be decomposed in the soil and absorbed by it. Decide ab¬ 
sorption power of calcareous soil to equal 46,822 Kg. of copper sulphate per hectare. Sug¬ 
gest that plants may absorb the copper in small quantities and inquire if this may not be 
turned to account in the treatment of diseases. (D. G. F.)

Gives experiments made with different fungicides. Concludes the best results were ob¬ 
tained from the use of Bordeaux mixture and copper-soda solution, the latter made with 4 
pounds 6 ounces copper sulphate, 6 pounds 10 ounces soda, and 26 gallons of water. Plants 
should be sprayed twice. (J. F. J.)

Gives an account of a scare in France over the treatment of tomatoes by Bordeaux mix¬ 
ture. Shows that the amount is too small to be injurious and is found principally in the 
seeds of the fruit. Refers to the fact that bread, coffee, tea, and especially cocoa contain 
large amounts of copper, as does also liver of beef. Refers to action of prefect of police.

Speaking of apple scab (Fusicladium dendnticum) recommends eau celeste (modified) as a

wheat rust ” gives suggestions as to method of using in experiment. (M. V.)

The departmental professor of agriculture is sponsor for the following statements which 
occur in a work designed for general distribution. For grape mildew (Peronospora) the Bor¬ 
deaux mixture has been found to give the most satisfactory results, but eau celeste, contain¬ 
ing a part of the hydrated oxide of copper in an immediately soluble form, is a verv active 
remedy, useful when vines are already attacked. Directions are given for making and ap¬ 
plying Bordeaux mixture and eau celeste. If liquid fungicides are preferable, ordinarily, to 
powders, the latter may be of great service when the berries begin to be attacked,, The two 
treatments may be combined, the Bordeaux or eau celeste being followed the day after by 
Skawinski, cupro steatite, sulfo steatite, or sulphated sulphur—the first two on vines still 
tree, the latter on vines already attacked. They should be applied mornings Avhen dew is 
on, or quiet evenings. Antliracnose attacks principally the berries of Alicante Bouchet and 
Carignane. The Aramon, a variety which has heretofore remained almost exempt, is now one 
of the most attacked by punctate antliracnose. No radical remedy is known. Four have 
beenused—sulphur, lime, cement, and gypsum. Employed separately they have some value, 
but are more efficacious when mixed in the following ways: ( 1 ) r sulphur and 5 - lime of Teil. 
(2) 1 sulphur and | cement; (3) 1 sulphur and ^ lime of Teil, 1 cement; (4) i sulphur and i 
lime of Teil, i baked plaster. These mixtures should be used copiously in still evenings or 
mornings when there is dew. The following wash is recommended for use in the spring on 
vines already attacked: Dissolve 50 per cent sulphate of iron in xvarm water, after haviu» 
Avet the crystals with 1 per cent of sulphuric acid. The substance should be put on some 
days before vegetation begins Avitli a brush or with a spraying machine. (E. F. S.)
