carried on for 5 years. An old orchard which had previously been in 

 sod was divided into 8 sections, to 4 of which ashes were applied annu- 

 ally at the rate of 100 pounds per tree. Tables are given comparing 

 the yield and keeping qualities of apples grown on treated and untreated 

 sections. The relative resistance of a number of varieties to apple scab 

 is also tabulated. The author summarizes the work as follows: 



"On the treated sections of the orchard the foliage in many cases was improved, 

 but it can not be said that the improvement was due to increased immunity from 

 the scab. 



" When the ashes were used the color of the fruit was much improved in aome sea- 

 sons with some varieties, but in a season which favored the perfect development of 

 the fruit none of the varieties showed any improvement in color as compared with 

 the same varieties on untreated sections. 



"Apparently the use of ashes had a general tendency to hasten the perfect devel- 

 opment of the fruit. When the season was not especially favorable to the perfect 

 development of the fruit it improved the keeping quality, but in a season very favor- 

 able to the perfect development of the fruit the ripening processes were generally 

 carried so far, where the ashes were, used, that the apples did not keep so well as 

 where no ashes were used. 



"The yield, except with the Baldwins, was greater on the treated sections; but 

 the data are not such as to make it safe to draw definite conclusions as to the effect 

 of the use of ashes on the yield. 



" Decided differences were shown hetween varieties as to the ability to resist scab, 

 and preliminary investigations indicate that this difference in resistant power is 

 correlated with structural peculiarities." 



Fourth report upon chrysanthemums, W. Miller {New York 

 Cornell Sta. Bui. 117, pp. 657-689, jigs. 12). — The author discusses the 

 economic status of the chrysanthemum, stating that chrysanthemum 

 growing in Xew York probably involves more capital than peach grow- 

 ing. The chrysanthemum has come to be one of the four main florist's 

 flowers. Suggestions are given on growing chrysanthemums at home. 

 The method of procedure depends largely upon the type of plant 

 desired. The use of crown and terminal buds in the production of 

 exhibition flowers is discussed. The terms as used in chrysanthemum 

 culture are distinguished as follows: "A crown bud is surrounded by 

 vegetative shoots and not by other buds. A terminal bud (in chrysan- 

 themums) is surrounded by other buds and not by vegetative shoots." 

 With some varieties the foliage and form and color of the flowers are 

 very noticeably affected by the choice of the terminal or crown buds. 

 The chief merits of crown buds are eaiiiness and large size. In all 

 other respects terminal buds are likely to be superior. A number of 

 references to the literature of the subject of crown and terminal buds 

 are given. 



The problem of control of color of chrysanthemums is discussed. In 

 regard to the factors of the problem the author says : 



"The choice of buds is said to he sufficient in some cases. Thus, J. H. Woodford 

 is advertised as shell-pink from terminal and pure white from crown buds. Over- 

 propagation is generally believed to weaken colors. Temperature and ventilation 

 (the two factors can hardly be separated in greenhouse jmictice throughout the
