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 enough to wash off much 
of the spraying mixture. The sun was out at 10:45 a. m. (8) 
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 ihe row were left unsprayed. 
On June 9 and August 20, the following records were taken on 
these trees:
