On the 22d of May the trees were sprayed with London purple at the 

 rate of one pound to two hundred gallons of water, for the purpose of 

 destroying the codlin moths. 



The first application of the fungicides was made two days later when 

 the apples were the size of large peas, and before any trace of scab was 

 apparent. Care was taken to cover every leaf and fruit, requiring aboxit

 to ten gallons of water.
