spraying we drive just as slow as the horses will walk, bringing the 

 nozzle of the machine in contact with every tree. 



I believe that when the orchard is badly infected with scab, it 

 should be sprayed twice before the blossoms open, and that clean cul- 

 tivation is just as esential as spraying. 



I am also thoroughly convinced that we did not spray late enough 

 in combatting the coddling moth, as our apples were almost entirely 

 free of worms until about the middle of August. 



After all, in order to make commercial orcharding the most profit- 

 able, we must not only spray, for spraying is only one of the many 

 essentials in profitable fruit growing, but we must cultivate, rotate, feed 

 and prune our orchards, for the success of one part of the work de- 

 pends on how well we do the rest. 



DISCUSSION ON SPRAYING. 



A. V. Schermerhorn of Illinois, who uses the liquid spray, was 

 called upon and said he beUeved much of Captain Lincoln's success was 

 due to the other treatment he gave his orchard. In arriving at con- 

 clusions, Captain Lincoln had compared results from his orchard with 

 results from neighboring orchards which have not received as good gen- 

 eral care. This is not a test at all, for if one is to arrive at any in- 

 telligent conclusion, the two orchards, or parts of orchards, should 

 receive the same treatment, except for the spraying. 



"I have nothing against the dust spraying," said Mr. Schermer- 

 horn, "but I would urge growers to be very careful in abandoning liquid 

 pumps for the dusters. The dust process has been thoroughly tested 

 in Illinois, by our Experiment Station and by practical growers, and as 

 a fungicide for apple scab it is an absolute failure." 



Dust spray is an absolute failure in controlling the apple scab in 

 Illinois. We want the facts in the case and not be misled. 



Mrs. Hodge — I have had a good crop of apples this year. I use 

 dust spray and never use any other. In 1904 I had 1,700 barrels of 

 good fruit, when I sprayed several times. In 1905 I made but one 

 application with less satisfactory results. 



Captain Lincoln — In regard to leaving check plots unsprayed, 

 I had a small orchard which was dusted only once, very early, and 

 fruit from it was very poor. It was poor quality because of worms, 

 rather than because of scab. 



Dr. Burrill — Dust spray has been tried carefully and thoroughly 

 in Illinois, but I do not know of a single individual who would ad- 

 vocate the dust spray in preference to the liquid. Sometimes it is
