from 80 to 100° P, In this temperature fames are given off, which 

 quickly destroy the fungus. 



We have obtained excellent results in treating this disease with 

 a solution made by dissolving half an ounce of potassium sulphide 

 to the gallon of water. This preparation is cheap and can be quickly 

 and effectually applied with any of the well known spraying pumps. 

 The greatest care should be exercised in making the second spraying, 

 which, by the way, should be at the same time as that mentioned for 

 the flowers of sulphur, in order to protect the blossoms from the fun- 

 gus. 



ANTHRACNOSE.* 



This is one of the most difficult of all the grape diseases to combat; 

 in fact we must admit that so far no reliable means of preventing it are 

 known. We can only suggest, therefore, such lines of treatment as 

 have given the best results, hoping that future investigations may throw 

 more light on the subject. 



In early spring, before the buds swell, remove, so far as possible, the 



wood showing the scars made by the fungus, and then treat the vines 



with a satura,ted solution (20 per cent, at 20° 0.) of iron sulphate. 



The French apply this by means of mops made of rags, attached to 



short handles. This is rather slow and awkward work, and -we prefer 



to do it with a spraying machine. As soon as vegetation starts watch 



the vines carefully, and at the first appearance of the disease apply 



with a sulphuring bellows a powder made of equal parts of flowers of 



sulphur and slaked lime. If this does not check the malady, try the 



sulphur alone. 



PEAR SCABt AND LEAF-BLIGHT.ij: 



Excepting the well known fire blight these diseases are the worst 

 enemies of the pear. They are especially prevalent in New Jersey, 

 Delaware, and adjoining States, frequently causing the loss of entire 

 crops of fruit and thousands of seedlings. The seedlings are especially 

 subject to leaf-blight, but are hardly ever, so far as we know, seriously 

 injured by scab. As the two diseases, however, are usually associated 

 on large trees, and as we have used the Bordeaux mixture successfully 

 on the seedlings, we would suggest that it be adopted for all and ap' 

 plied as follows: 



Seedlings. — Make flve applications, the first when the leaves are one- 

 quarter grown, others at intervals of ten days until the trees are 

 budded. 



Large trees. — Spray five times ; first when the fruit is the size of peas, 

 and thereafter at intervals of twelve or fifteen days. 



For applying the mixture to trees less than 12 feet high, and especi- 

 ally to seedlings in the nursery, the knapsack pumps provided with the 

 improved Vermorel lance and nozzle will answer.
