MR.PERKINS. Thank you. Now, I want to ask an 

 abstract question, on pears. What would be the effect of 

 planting 500 Beurre Bosc trees all by themselves? I have 

 an orchard of several thousand trees and was thinking of 

 putting in some Beurre Boscs. They are sterile, as I gather 

 from your figures. What would you suggest as some other 

 pear tree to use for purposes of cross-pollination ? 



PROF. CHENOWETH. If I were going to plant 500 

 trees, I don't believe I would want to put them in solid 

 blocks unless I had many others growing near. If you have 

 others near, you would perhaps get a fair degree of cross- 

 pollination, but I should think you would get better results 

 if you alternated, with probably two or three rows of 

 Beurre Boscs and then a row of, say, Anjou, 



MR. PERKINS. I want to get something in the way of 

 a -fall fruit. 



PROF. CHENOWETH. The Bartlett is seK-sterile. It 

 doesn't follow that it won't cross-pollinate, because it does, 

 but it won 't pollinate itself. Th6 Bosc would also pollinate 

 your Bartletts; also the Bartlett and Seckel cross-pollinate 

 very nicely. 



QUESTION Could you tell me anything about experi- 

 ments on, for instance, the Northern Spy, as to what any 

 experiments have shown as to their being self -pollinating? 



PROF. CHENOWETH. That is a self-sterile variety. 

 Professor Waugh recites a case of a large orchard in Ver- 

 mont that never has borne a paying crop. It is a large, old 

 orchard, and he attributes it entirely to the fact that the 

 only other variety planted in the orchard is the Rhode Island 

 Greening, and that blossoms and is gone before the Spy 

 comes into blossom. The Spy is a late-blooming variety, 

 and in order to cross-pollinate that, you have got to get some 

 varieties that would blossom rather late. We have no record 

 at the College of the blossoming period of the Spy, but wa 

 have of Ben Davis and Baldwin, York, Wealthy, Mcintosh 

 and a few more, and they all blossom at approximately
