of 1. 014 specific gravity, or i to 20 (i gallon Commercial cen- 

 centrate to 19 of water), and in the other orchards a spray of 

 1.028 or I to 10 ( I gallon of commercial concentrate to 9 of 

 water) were applied when the trees were dormant the latter part 

 of April. After the dormant spray was applied all plots were 

 sprayed alike and on the same date with the usual lime-sulphur 

 arsenate spray, two applications before blossoms open and two 

 after. It will be seen that in this test the dormant spray was 

 of little value for the control of scab.
