EXPERIMENT STATION BULLETINS. 123 



the weights of these several pickings from each plat expressing the relative 

 productiveness of the variety for the year. 



The past winter and spring have tested the comparative hardiness of 

 varieties more severely than usual. Many of those usually thought to be 

 lacking in this particular, such as Anna Forest, Henderson, Jewell and a 

 few others were nearly or quite ruined, while others not usually considered 

 deficient in hardiness, have so far suffered as, in a greater or less degree, 

 to affect the quality or quantity of their yield of fruit. Among such we 

 may mention Cornelia, Crimson Cluster, Gold, Goldsmith, Hoffman, Long- 

 fellow, Prince of Berries, Sucker State and perhaps others. This fact, 

 will have, doubtless, in some degree aff'ected the results given, but to what 

 extent seems only determinable from the results of repeated trials. 



For several weeks prior to the picking season, the conditions had been 

 favorable to the development of size and quantity of fruit, while the 

 advent of excessively hot, drying weather hastened and shortened the 

 ripening season, deteriorating the size and probably occasioning the 

 abortion of many of the later specimens, which, with the prevalence of 

 more favorable weather, would probably have matured. 



The following tabulation is extended across two opposite pages, the con- 

 nection being indicated by the use of numbers. 



The form and color of the fruit, together with the prevalence of fungi, 

 are given by means of abbreviations placed at the head of the table. 



Insects have not, so far, proved troublesome. Several years since the 

 leaf -roller {Phoxopteris fragarice, W. & R. ) became very abundant. As 

 the larva invariably draws the opposite halves of the leaflet closely 

 together, its presence is readily observable. Advantage was taken of this 

 circumstance to crush the larvae in these hiding places, which was so 

 thoroughly done that very few appeared the following season. The same 

 process was applied to these, since which they have almost wholly dis- 

 appeared. 



The dates of origination or introduction are, in most cases, to be consid- 

 ered as mere approximations, many of them having been inferred from the 

 dates of introduction, or from recollection of our first acquaintance with 

 the variety. 



The column headed "Hardiness" indicates the condition in which the 

 plants came through the past winter, which, in a few cases, may have been 

 in some degree affected by local peculiarities of soil, and possibly in a few 

 instances by their previous condition. 



For the reasons stated, the results given under the head of " Productive- 

 ness" to some extent need a repetition of the trial, in other seasons and 

 soils, before being accepted as conclusive.
