Halves at Different Uimes. 



The parts sprayed when in full bloom gave the better results. 



Experiment Jf, in the orchard of W. S. Mudge, Hartland. This 

 is a small orchard of about 100 trees, mostly Baldwins. It has 

 been tilled for several years, and the trees are of good size, 

 thrifty, and very free from insect pests and diseases. At blos- 

 soming time one had to hunt several minutes to find a bud-moth 

 or case-bearer in this orchard. It has been sprayed for two sea- 

 sons with Bordeaux mixture and Paris green. The owner states ' 

 that the fruit has not been noticeably scabby or wormy in past 

 years. In 1897, |500 worth of fruit was taken from this little 

 orchard. One row of thirteen Baldwin trees was used in this 

 experiment. (1) On the morning of May 15, three trees were 

 sprayed with 45 gallons of Bordeaux. A very few blossoms 

 were partly open on the south side of one of the trees; perhaps 

 five per ct. of the clusters had the center blossom half open. No 

 blossoms had opened on the other two trees. Weather sunny 

 and windy. (2) Three more trees were sprayed with 40 gallons 

 of Bordeaux on Friday morning, May 18, when they were in full 

 bloom. Weather cool, partly cloudy. (3) Monday afternoon, 

 June 11, three other trees were sprayed with 40 gallons of Bor- 

 deaux. At this time the fruit had set, but had not turned down. 

 (4) Four trees were not sprayed. 



The comparative set of fruit was estimated on June 11 and 

 August 21:
