WEATHER RECORD. 



During the time when the spraying was made the weather condi- 

 tions were favorable, with one exception, as the days were warm and 

 the wind was light. 



The rainfall at Delaware, reported to Mr. J. Warren Smith, director 

 of the Ohio section of the Weather Bureau, by the local observer, 

 shows that no precipitation was recorded for over a week after the 

 first spraying was applied. 



On the afternoon of May 22, the day that the second spraying was 

 made, 0.53 inch of rain fell, and this was followed by continued rain 

 or showers on every day for the balance of the month, 1.73 inches 

 being recorded during this time. The first half of the month of June 

 was also very rainy, especially during the first week, the rainfall on 

 the 6th amounting to 2.91 inches. The total for the month was 4.97 

 inches. 



Very little rain fell in July after the 13th, which was the date of the 

 third spraying. On the 18th 0.23 inch was recorded, and this was the 

 largest amount on any day during the month. 



From the fact that the foliage of the trees on rows 4, 5, 6, and 7 was 

 well covered with poison late in September, it is probable that the 

 July rains had little influence on the results of the last spraying. 



AMOUNT OF MATERIAL USED. 



The average amount of spray material used by us on each row was 

 35 gallons. During the second spraying on row 6 four nozzles were
