In Mr. Goff’s calculations the cost for labor in making the treatments 
amounts to more than half the expense. 
It seems probable that it would be profitable to make the first appli¬ 
cation earlier than was done this year, and there is no reason why this 
application or the next should not be combined with London Purple or 
some other insecticide, and the tree protected from insects and fungi 
at the same time. Mr. Hatch closes his report thus: 
What we now need is to determine the correct amount of the copper mixture to use, 
the times best suited to its application, and what combinations to make w u b insecti¬ 
cides, and a new era in fruit culture will be inaugurated.

POWDERY MILDEW OF THE BEAN. 
Under date of December 13 Mr. O. N. McCallan, of St. George’s, Ber¬ 
muda, writes that on the 20th of November his section was visited by 
a very heavy fog, and a few days later he noticed that his crop of six- 
weeks beans was badly mildewed, the fungus being one of the Ery- 
siphece , probably Erysiplie communis , Lev. He immediately gave the 
plants a thorough dusting with flowers of sulphur, and in a week the 
fungus had entirely disappeared and the plants produced a good crop. 
Mr. McCallan was highly pleased with this result, as he has several 
times lost his entire crop of beans from the attacks of the same fungus. 
In this country, peas, especially those planted late in the season, are 
often attacked by mildew, which in all probability might be easliy 
prevented by the timely application of flowers of sulphur or some other 
fungicide. A powder made by mixing equal parts of air-slaked lime 
and flowers of sulphur will be found a very good remedy for this dis¬ 
ease. The powder should be dusted on the foliage at the first appear 
ance of mildew and the operation repeated every ten or twelve days, or 
more often if there is an abundance of rain. 
If one has a spraying machine a solution made by dissolving 3 ounces 
of carbonate of copper in 2 quarts of aqua ammonia diluted to 22 gal¬ 
lons will be found an efficient remedy against mildew. This solutiou 
should be applied every twelve or fifteen days, beginning at the first 
appearance of the disease. Three ounces of carbonate of copper can be 
bought for 10 cents, while the ammonia will cost about 10, making the 
total cost of the 22 gallons 20 cents; certaiuly a very cheap fungicide. 
If carbonate of copper is not obtainable it may easily be prepared by 
first dissolving sulphate of copper (blue stone) in water and then adding 
ordinary washing soda. The precipitate formed on the addition of the 
latter substance is carbonate of copper, and in order to obtain it the 
liquid only needs to be drawn off and the copper carbonate dried.
