Although no further spraying was done the results were very 

 marked in preventing the mildew and lessening the black rot. On 

 the four rows unspra^^ed the black wart was much more abundant 

 than on those sprayed. 



Phim trees. Sprayed May 11th and 21st, June 1st, 5th and 13th. 

 On two rows the Bordeaux mixture was used at the ordinary strength, 

 two rows at one-half strength, and two rows were uusprayed. 



The results noticed were, that there were a less number of warts 

 on the sprayed trees than upon those unsprayed. The leaf blight 

 did not seem to be affected, there being about the same amount on 

 each plot and tlie leaves fell prematurely from all the trees alike. 



Peach trees. Sprayed the trees May 11th and 23d and June Ist, 

 oth and loth with the Bordeaux mixture, one-half strength. One row 

 of four in the orchard was left as a cl^eck. This spraying was not 

 beneficial, as those trees ucsprayed looked the best, and there was 

 some rot on nil of them." 



[In the experiment witli grapes Mr. Cook seems to have made a happy hit, as the spray . 

 ing of June 13th was .just before hot, moist weather, when mildew and rot started 

 vigorously in other places. It is not always possible to do this, and consequently more 

 frequent applications must be made, in order to secure the surest results. 



REPORT OF E. A. ESTABROOK, 



GRAFTON, MASS. 



Mr. Estabrook treated grape vines only. He reports as follows : 

 "April 28th, I sprayed several rows of vines with the suli)hate of 

 iron, one pound to two gallons of water. The buds had started so 

 as to show the pink tinge of the leaves, and the mixture burned them 

 somewhat. When the shoots were from six to twelve inches long 

 with the young fruit-bud clusters showing, and some of them even in 

 bloom, we sprayed a part of the same rows with the Bordeaux mix- 

 ture at one-half full strength. Owing to a mistake, the mixture not 

 being thoroughly stirred, some of the vines were seriously injured 

 and the apparent results at the time discouraged me, so that no 

 further spraying was done. 



But subsequent results proved that even that one application of 

 sulphate of iron and one of Bordeaux mixture was of great benefit. 

 The fruit being far superior to that of adjoining rows not sprayed. 

 These were Concords, and the adjoining rows of Wordens were 

 similarly benefitted, but the next row of Moores Early, being more
