 is a ready and profitable home market in Vermont for 25 times the 

 amount of cherries now grown, and that cherries are easier to grow 

 than potatoes. 



Facts and opinions about plums and plum growing in Iowa, 

 J. Craig {Iowa Sta. Bui. hG.pp. 233-303, figs. J^).— This bulletin «ets. 

 forth some of the facts obtained in an investigation of the plum indus- 

 tr}^ in Iowa relative to the character, blossoming period, hardiness, 

 popularity, etc., of a large number of varieties grown within the State; 

 presents an epitome of the experiences of many orchardists on plum 

 culture in diflerent parts of the State; describes 118 varieties of plums, 

 and gives directions for planting, cultivating, pruning, spraying, thin- 

 ing, topgrafting, selection of plum stocks, and the planting of plums 

 with regard to cross pollination. 



The relative hardiness of the fruit buds of a large number of varie- 

 ties of plums grown in ditierent parts of the State was determined by 

 examination of buds sent in to the station in the spring of 1899. The 

 data obtained are tabulated, and are instructive '"from the standpoint 

 of exhibiting class characteristics, varietal differences, and effect of 

 locality upon variety." 



The characteristics of all the leading types of plums, as shoAvn by 

 their behavior in Iowa, are sunmiarized comparatively in tabular form. 

 From these data the author bases his belief that the chief reliance of 

 Iowa plum growers must be placed upon varieties of the Americana 

 group. The improvement of this group of plums by Iowa horticul- 

 turists is pointed out. From circular letters addressed to leading fruit 

 growers, the varieties De Soto, Hawkeye, and Wyant of the Americana 

 group and Minor of the species Hortulana are shown to be the most 

 popular plums grown in Iowa for both market purposes and for home 

 use. The Domestica and Japanese plums are practically uncultivated 

 in Iowa except in the l southern tiers of counties. Lombard and 

 Green Gage of the Domestica and Burbank and Abundant of the 

 Japanese are the favorite varieties grown. 



The author suggests lists of varieties of plums for planting in each 

 of the 9 tiers of counties of the State. The curculio, gouger, aphis, 

 and rot are mentioned as the most serious enemies of native and 

 Domestica plums. Of the Japanese plums, rot is the enemy of great- 

 est importance. 



Fertilizing self-sterile grapes, S. A. Beach {Ninv York State Sta. 

 Bui. 169, pp. .}.j1-o71, pU. ^).— Work of the author in testing the 

 self -fertility of grapes has been previously noted (E. S. R., 11, p. 248). 

 The present work reports a study of the question whether some grapes 

 are better than others for fertilizing the self-sterile kinds. The work 

 has been carried out in 3 different sections of the State. Cross pollina- 

 tion was effected by brushing the bunches of the 2 varieties to be cross
