At Lincoln (table 9) , the same machinery was used as the year 
before. Bordeaux nozzles were used for the petal-fall spray on 
all but one plat. The pressure was not as constant as it should 
have been, varying from 175 to 250 pounds. No tower was used, 
but one man sprayed from the top of the engine house on the rear 
of the machine. The efficiency of this schedule was: No. 5, 95 per 
cent; No. 4, 94.5 per cent; No. 3, 94 per cent; No. 1, 93.5 per cent; 
No. 2, 90 per cent; and No. 6, 79 per cent. Slightly more than 10 
per cent of the larvae entered at the calyx. Certainly the schedule 
would have been more efficient had the pressure been more con- 
stant, and had the principal part of the spraying been done from a 
tower.
