infested with the scab fungus, and on this account the spraying 
had no perceptible effect. This experiment simply adds to the 
already sufficient evidence establishing the fact that treatment 
of pear scab to be effectual must begin early in the season. 
The methods of spraying used by this Station were employed 
by Mr. W. A. Smith in treating other parts of the orchard in 
which the experiments were conducted, and additional data were 
thus secured. Mr. Smith’s treatment showed that: . 
1. Some trees sprayed but once, and that before the blossoms 
opened, showed some injury to the fruit as a result of the treat- 
ment. The injury became apparent during the rainy period that 
occurred the latter part of May and the first of June.“ From 
May 16 to June 5, a period of 21 days, it rained every day. 
14 Some idea of the climatic differences of late spring and early summer of 1894, as compared 
with 1893, may be obtained from the meteorological data taken from the records of observa- 
tions made at the Station as shown in table XII on the following page. The Seckel pear blos- 
‘gsoms began to open in 1893 on May 19, and in 1894 on May 3. The weather conditions from the 
blossoming time to the last of June includes the spraying season. 
The lowest average amount of sunshine for the period referred to in 1893 was during the week 
from June 16 to June 22, when the sun shone but 31.9 per cent. of the time it was above the 
horizon, but in 1894, during the week from May 17 to May 23, there was but 23 per cent. of the 
poss'ble amount of sunshine, and during the following weeks but 14 per cent. and 39.4 per 
cent. respectively, showing that during these three weeks the weather was exceptionally cloudy. 
The rainfall record shows that a little more than three times as much rain fell in 1894 as in 1893 
durisg the period from blossoming to the ist of July, and the total rainfall during the three 
weeks from May i6 to June 5, 1894, 7.38 inches, nearly equal to the rainfall of the entire months 
of May and June in 1893. The average temperature for June in 1893 was 71.7° Fahr., while for 
June, 1894, it was but 68.3, and this notwithstanding the pleasant weather after June7. It is 
evident that the weather for three weeks after blossoming time in 1894 was exceptionally cold, 
dark and rainy, and vegetation could but feel the unfavorable effects of such weather, especially 
since it was followed by drought,
