been somewhat injured by canker. All bloomed very full during 
the season of 1900 when the experiment was made. Three trees 
were sprayed in each lot. (1) Sprayed Wednesday forenoon, 
May 16, with Bordeaux mixture and Paris green when the bloom 
had not yet fully opened. The spraying was rather light. (2) 
The trees sprayed when in full bloom. At harvest time it was 
found that the apples were fewer on the trees sprayed in bloom, 
but that they were larger and finer. If any conclusion is to be 
drawn from this experiment it seems to be that the spraying in 
bloom was a thinning process. Mr. Freeman writes: “ My con- 
clusions drawn from experiments last season are that the yield of 
both my Twenty Ounce and King sprayed in full bloom was very 
much diminished; in fact, was nearly a failure. What few fruits 
were left were fine. I had a full blossom.” 
THE RESULTS OF THE EXPERIMENTS OF 1900. 
The experiments of 1900 neither prove nor disprove the value 
of spraying fruit trees when they are in bloom. In a year when 
sprayed and unsprayed trees alike give good crops, the results of 
spraying experiments are likely to be unsatisfactory. The tests 
must be extended over several years before it will be safe to draw 
definite conclusions. So far as the experiments of the past sea- 
son are concerned, however, two general statements may be 
made: 
1. In general, the trees sprayed when in full bloom bore no 
better crops than those sprayed either before the blossoms opened 
or after the fruit had set. 
2. There was no apparent injury to the blossoms on trees 
sprayed when in full bloom. 
The only exceptions to the first statement were the Maiden 
Blush and Twenty Ounce trees in the orchard of Harry Jackson 
and the results in Mr. Bugbee’s orchard. The fuller set of fruit 
on the east sides of Mr. Jackson’s trees than on the west sides 
was a marked difference in favor of spraying in bloom. The com- 
parative fruitfulness of many other Maiden Blush and Twenty
