scab, although no blue vitriol had been used in the orchard. The 

 orchard has been fairly productive, but not profitably so. 



Experiment 1 (Jackson). — (1) Twenty large Baldwin trees, 

 fairly uniform in size and vigor, were selected in one row. All 

 the trees bloomed full. The first spraying was done Monday 

 morning, May 13, when the blossoms were just ready to burst, 

 but none had yet opened. Sixty gallons of Bordeaux (with Paris 

 green) were applied to five trees. Weather sunny and rather 

 windy. (2) The second lot of trees was sprayed Monday, May 20, 

 at 7:30 a. m., eighty gallons of Bordeaux (and poison) being used 

 on the five trees. Fully ninety per ct. of the blossoms were 

 open at this time. A light drizzling rain came up at 8:30 a. m., 

 and lasted till 9:30 a. m., but not long enongh to wash off much 

 of the spraying mixture. The sun was out at 10:45 a. m, (3) 

 The third lot of trees was sprayed Saturday, June 9, when the 

 fruits had set, but had not yet turned down. About the same 

 amount of Bordeaux was used as in previous sprayings. Weather 

 partly cloudy, the sun coming out bright occasionally. (4) Five 

 trees in the row were left unsprayed. 



On June 9 and August 20, the following records were taken on 

 these trees:
