liquid is inexpensive, costing only from one to two cents per barrel be- 

 sides the labor of application, and with proper appliances and economy 

 of labor the spraying can be done for a very small sum per tree for the 

 short time when it is necessary to spray. Mr. Geo. S. Powell of Ghent, 

 N. Y., is reported to have saved a large crop of cherries during the sum- 

 mer of 189^, a season of unusual rainfalls, by the above treatment. Paris 

 green cannot be safely used on the cherry foliage. 



The Quince. 



The leaf blight and rust on the branches and fruit can be destroyed by 

 the use of the Bordeaux mixture. This should not be applied, however, 

 after the fruit is more than one-half grown. 



The Grape. 



The insects attacking the grape, except the phylloxera which seldom 

 injures the American grape, can be destroyed. by the use of Paris green, 

 and the black rot, the downy and powdery mildew and the anthracnose 

 are all prevented from doing harm by the use of the Bordeaux mixture 

 and the copper sulphate solution. The former should never be used 

 after the berries are one-half grown. One of the greatest difficulties in 

 growing the grape in New England is the weakening of the vines by the 

 fungous pests, and vines regulai'ly sprayed to prevent this injury gain in 

 strength from year to year and large and satisfactory crops are the 

 result. We have to compete with fruit from the large vineyards of more 

 favorable grape growing sections than New England, but the native 

 fruit when well grown and ripened can be put upon our local market 

 in so much better condition than that coming from a long distance, that 

 it is sui'e to bring a much higher price. Fig. 3 illustrates a sprayed and 

 Fig. 4 an unsprayed vine. 



The Raspberry and Blackberry. 



The orange rust and leaf blight, the two most sei'ious obstacles to the 

 growth of these crops, are easily kept under control by spraying with 

 the Bordeaux mixture. 



The Currant and Gooseberry. 



The currant worm is destroyed by the use of hellebore powder ap- 

 plied in water or in a dust form when the leaves are wet with dew or 

 rain. Attention should be given to the bushes very soon after the leaves 

 open and spraying be clone upon the first appearance of the worms. 

 The leaf blight, a fungus that causes the leaves to fall off in August, 

 may be prevented from doing injury by the use of the Bordeaux 

 mixture. 



The Strawberry. 



While spraying for the destruction of insects and fungous pests 

 attacking this fruit does not give so marked results as with many other 

 crops, it has been conclusively shown in many experiments that the rust 

 is largely reduced by the use of the Bordeaux mixture, and the two 

 insects, the black paria and the crown borer, may be largely prevented 

 from doing serious harm if Paris green is used in the mixture. 



The Potato. 



Numerous experiments and general practice go to show that this crop 

 cannot be grown with the best results without the use of insecticides 

 and fungicides. The Colorado beetle and the flea beetle are destroyed 

 by the use of the Bordeaux mixture and Paris green, and at the same 

 time the leaf blight and the potato rot fungus may be largely, if not 

 entirely, prevented. The growth of the potato scab on the tuber can be 

 largely prevented by the use of corrosive sublimate or sulphur.
