made runners during the season. In one of these there ^ as D I fruit jjerm and the other 

 contained one truss. 



To determine the relative productiveness of Jucunda we examined a stool of Wilson's 

 Albany, apparently of the Bame Btrength of Jucunda, ami found it to contain IS germ 

 trusses. Two plants of Wilson's Albany that had made runners through the summer, in 

 one of these there wen- ii and in the other 4 trusses. NY\t we selected three similar 

 plants of Longworth Prolific. The stool that had been kept free from runners had made 

 9, and the other two that had made runners, one contained one and the other two 

 germ trm 



These observations go to show that Jucunda like all other varieties that throw out 

 runners, to the end of the season, becomes bo exhausted as to produce but few or no 

 fruit hints. While those which are kept freed from runners, enlarge into stools, and store 

 up in leaf and fruit buds the nourishment which under neglect, the plant would waste in 

 the multiplication of its numerous runners. In view of this,, facts do we ask why it is 

 that Jucunda is a success in the hands only of a few ? We answer, the majority subject 

 every sort to the same treatment that they bestow on their Wilson's Albany, without a 

 knowledge of the fact thai the Wilson's Albany does for itself naturally what Mr. K. 

 does for his Jucunda. In other words, the Wilson's Albany after a certain period ceases 

 to produce runners but does not at the same time cease to ii - row. This growth remains 

 with the plant and greatly increases its size by the addition of a large number of both 

 leaf and fruit buds. And In this way it becomes the lazy man's variety. Subject the 

 Jucunda to the sane- treatment that we do our Wilson's, and we hear the oft repeated 

 exclamation. Humbug sort ! worthless! unproductive ! and the like. 



We do not asseri that Mr. Cor the few successful cultivators of Jucunda all under- 

 stand the true tl ry of their success ; they have observed the fact, that plants subject- 

 ed to certain modes of treatment produce certain results, and shape their culture accord- 

 ingly. 



With all the care bestowed on Jucunda and the high rate- obtained from the fruit, is it 

 not probable for fruit alone that its value at Pittsburgh is not equal to that of Wilson ? 

 If so, why divide the ground equally between the two varieties?

Prof. J. B. Turner, of Jacksonville, then read the following 

 paper on the 



ROTTING OF GRAPES AND BLIGHT OF PEAR TREES. 



My attention was called to the distinctive forms of Grape Hot and Pear Tree BUi/ht, 

 known in the West as early as the year 1848 ; at which time I wrote a series' of papers 

 for the Horticulturist, at the request of the editor, the Incomparable Downing, some- 

 what minutely describing and defining some of the several forms of those diseases as 

 they had then appeared in the West. Previous to the writing of those articles, I am 

 not aware that any effort had been made to distinguish between the multiform kinds of 

 Pear tree blight that attack our trees, and the two leading, and entirely distinct forma 

 of rot that affect our Grapes, characterized and described in those papers, published
