TABLE IV. 



As will be seen, there is a marked difference in every instance 

 save one, in favor of the sprayed trees. The highest per cent of 

 fruit entirely free from scab, was obtained from the use of the eau 

 celeste, the gain being fifty-two and nine-tenths per cent, or more 

 than half of the crop. 



The greatest actual gain so far as marketable fruit is concerned, 

 however, was obtained from the use of the stronger ammoniacal 

 solution of copper carbonate. The actual increase of No. 1 fruit 

 amounting to nearly sixty-five per cent. It is quite possible that 

 this difference is largely due to the later application of this solution. 



The results obtained from the use of the copper carbonate in sus- 

 pension, will not warrant us in advising that mixture. Other tests 

 were made in Mr. Pope's orchards, as also in Mr. Woodward's 

 orchard at Winthrop. The indications in every instance pointing 

 toward marked benefit from the use of the copper solutions. 



As showing the necessity of doing something to check the disease, 

 I may note the condition of certain trets in Mr. Woodward's orchard.
