DR. WHETZEL. These spot diseases all appear to 

 have come from Oregon, or the west. [Laughter], Tho 

 reason is that they got their sight sooner then we did, that's 

 all. We have some in the east, but the truth is that a large 

 number of these peculiar spots — that is, the Jonathan spot 

 and the Fruit Spot — appear to be a type of scald. You 

 have seen the scald on the Greenings. 



MR. YEATON OF MAINE. Would spraying in tht 

 fall, after the leaves have fallen, spraying the ground 

 thoroughly, saturating it with lime-sulfur, be of sufficient 

 assistance or benefit to us in controlling the apple scab to 

 warrant doing it? 



DR. AVHETZEL. The question is, will it be sufficient- 

 ly profitable to warrant us in spraying the leaves after they 

 fall in the autumn, in order to kill the fungus on the leaves? 

 Well, now, I will tell j^ou a story which will illustrate this, 

 T think. It isn't a funny story. Some of you must know 

 the black rot on grapes, in which the bunches turn black 

 and hang on the vines in winter. The disease is something 

 like the apple scab. It produces spore bodies inside of the 

 black grape, which produce these spores which are shot in 

 the spring the same as the apple scab fungus. A couple of 

 years ago, when Dr. Reddick was working in a vineyard in 

 i\ew York State, the hired man in this particular vineyard 

 thought there ought to be some way of killing this black 

 rot. He suggested spraying them thoroughly in the fall, 

 and Dr. Reddick said that wouldn't do any good but this 

 hired man thought he would try a little experiment of his 

 own. He took a bunch of mummies and hung them over- 

 night in a barrel of strong vitriol that they used there for a 

 stock solution, and the next morning he took it out early 

 and hung it away down in one of the vines right near a lot 

 of blossom clusters and then waited. Along in the summer 

 when the black rot became apparent, one day he said to Dr. 

 Reddick, "Doc, come down here; I have something to show 

 you," and he took him down to this particular place, and
