The Prevention of Peach Leaf-Curl. 353 



Experiment Y. 



The trees included in this plot were also selected from one of the 

 orchards belonging to Mr. Lutts. Thev were all of the Beer's Late 

 variety and were inclosed on three sides by unsprayed trees. They 

 curled badly in '98, though not so much as the Ell)ertas, and have 

 not been sprayed until the past year. The trees are six years old 

 and have about twenty thousand leaves to the tree. There was no 

 crop in '99. A plan and table of results follow, as in the preceding 

 experiments. 



Plan of Experiment Y. 



From Mr. Lutts' block of the Beer's Late variety. The number and arrange- 

 ment of the trees is the same as in experiment IV and the signs used have the 

 same significance as in that experiment.
