Professor von Schrcnk, and a number of others and they give it as 

 their opinion, (which coincides with what my experience has proven 

 so far) that the dust spray is not equal to the Hquid spray, but in my 

 case, it is a question of whether I would spray at all or not. It is 

 simply an impossibility for me to ever spray my orchard with the 

 liquid spray, and so I began to study to see if I could not find some 

 way to get on this dust spray. As a result I have had seven dusters 

 at work, two of them large machines that go in a wagon, five of them 

 small machines that hang on your shoulder, the same as the Calhoun 

 Seeder does, and run just as easily, and with those machines I have 

 sprayed during the past summer 240 acres, three times. The first 

 dusting was just after the blossoms dropped, and the next dusting 

 was about ten days later. It then began to get dry, and I had to get 

 a time in which we could dust so that the dust would stay upon the 

 leaves or the young apples, and so I kept putting it ofif thinking possi- 

 bly to get a favorable time, but I did not, and the last dusting or spray- 

 ing was done in the middle of August. I feared then that perhaps we 

 might have the bitter rot, and so I thought I would use it as a preven- 

 tive. I am here to say that I am satisfied with the use of the dust 

 spray. I don't know that it is as perfect as the other; I don't believe 

 it is, but I can put it on three times while you put the liquid spray 

 on once. This last summer was not a fair test because through the 

 whole summer you could get out in the orchard almost any time with 

 a wagon load of water, but some years it is almost impossible to draw 

 five barrels of water through the orchard and spray the trees. With 

 these little hand spraying machines the men go out at four o'clock 

 and dust from that time until eight o'clock in the morning, and that 

 is a half days work, and I pay them for it. If they want to work the 

 rest of the day we would pay them for that. We go over the ground 

 quite rapidly. I used ten pounds of lime, one pound of Paris Green and 

 one pound of dry Bordeaux mixture, and that is the mixture that I 

 made. This dry Bordeaux I bought from Liggett Brothers, New York, 

 large wholesale druggists, who make a dry Bordeaux of their own and 

 sell it. They manufacture also a mixture of Bordeaux and Paris Green. 

 I sent for a lot of that. It is mixed there and is shipped in barrels. 

 The mixture cost me nine cents a pound, the dry Paris Green fourteen 

 cents a pound, and the Bordeaux mixture cost me twenty cents a 

 pound. They mixed a good deal of lime with it, in order to sell it for 

 that price. 



Now I tried another experiment on 40 acres. I took Hammonds 

 slug shot as the poisonous matter ; I took Hammond's grape dust as 

 the fungicide. I wrote to him and he said he didn't know that it
