Experiment III. — Table 2. — A Comparison of Varieties. 



In the Bordeaux mixtures used iu the above tables, the first figure represents 

 pounds of copper sulfate, the last gallons of water, aud the middle one, separated 

 from the others by dashes, represents pounds of unslaked lime. When copper 

 sulfate or lime is used alone with water, the last number represents gallons of 

 water and the first the copper sulfate or the lime in pounds. 



Experiment IV. 



■ Experiment IV was made upon a young Elberta orchard belong- 

 ing to Mr. Henry Lutts, situated two miles east of Youngstown in 

 the northwestern corner of Niagara county. The orchard had 

 received no treatment before '99. The trees have been set five 

 years and were badly attacked with curl in '98. There was no crop 

 of fruit in the past season. The estimates have all been made by 

 actual counting and the results are given in a table following the 

 plan of this experiment. As may be seen from the plan, there are 

 eleven rows of trees, with sixteen trees to the row. Checks are 

 indicated by the plus sign, those treated with Bordeaux 6-8-50 by a 

 square, and those with Bordeaux 3-3-50 by a tilted square. Lime 

 1-5 is represented by an inscribed line, lime 1-3 by an inscribed tri- 

 angle, and hme 1-2 by an inscribed square.
