Insects, insecticides, and fiuujicides (pp. 307, 308). — Brief notes on 

 experiments in the treatment of the flea beetle, currant worm, potato 

 beetle, gooseberry mildew, and the disease of the hollyhock {Puccinia 

 malvaccarum). The combination of hellebore for the currant worm and 

 potassium sulphide for the gooseberry mildew did not prove satisfac- 

 tory as far as checking the mildew was concerned, though tlie fungi- 

 cide alone gave good results. Dipping tomato plants in a solution of 

 Paris green at time of planting largely prevented the ravages of the 

 potato beetle. The x)lant jirotector, tested in 1889, was used again in 

 1890 with satisfactory results. 



Eeport of AcTiNa PoMOLOGisT, G. W. Churchill (pp. 309-351).— 

 In 1890 there was a general failure of the fruit crop in western New 

 York, except in the case of grapes and strawberries. The failure of the 

 apple crop was especially discouraging, as this was a year when an 

 abundant yield was expected. Causes of this failure are briefly dis- 

 cussed in this report. 



Grapes (pp. 310-332). — In recent years much attention has been given 

 to the culture of grapes in New York, but many farmers have not taken 

 sufficient i)ains to plant varieties adapted to the peculiarities of local 

 soils and chmates, so that much inferior fruit has been put upon the 

 market. The profits of the business have thus been greatly reduced. 

 Certain diseases of the grape have also been very troublesome. The 

 report contains extracts from correspondence showing the benefits of 

 spraying vineyards with fungicides. The following diseases of the 

 grape are described and suggestions are given for their treatment: 

 Black vot [Pliysalospora hidivcUii), downy mildew (Pcronosporaviticola), 

 anthracnose (*S^j/mceZomrtrt«<j;er<j^wm),powdery mildew (C/';tciM«t?rts/;ir«7is), 

 grape leaf blight {Cercospora viticola), white rot, and bitter rot. There 

 are also descrix)tive notes on 17 varieties of black grapes, 15 of red 

 grapes, and 13 of white grapes. 



Peaches (pp. 332^34). — Thus far no variety of peach has been found 

 that can be relied upon to produce a crox) with sufficient regularity to 

 make orchards remunerative in the region of the station. The author 

 urges the necessity of experiments in cross-fertilization and selection 

 of seed with a view to producing a variety suitable for this section. 

 The station hopes to undertake work in this direction before long. 



Some common fungous diseases and their treatment (pj). 334-339). — 

 Notes on treatment of the diseases of grapes mentioned above, and on 

 apple and pear scab {FusicJadium dendriticum and F. pijrinum), and the 

 black knot of the plum and cherry. 



Insects and remedies (pp. 339-315). — Brief notes on insects injurious 

 to the trees aud fruit of the apple, plum, and peach. 



List of varieties of fruits (pp. 310,317). — This includes 13 varieties of 

 apples (14 Eussian), 1 of crab apples, 20 of pears, 15 of plums (2 Kus- 

 sian, 1 Japanese, and 2 American), 11 of peaches, 1 of cherries (Eussian), 

 and 1 of grapes, planted in 1890, The varieties planted in previous
