26 AGRICULTURE OF MAINE. 



sound wood, so the healing can go on. All of these things are 

 business propositions and frequently a man has to do his 

 pruning when the time is convenient, and so with us, we gen- 

 erally come down to a time when it is economical to prune 

 because other work is not pressing. Really, that seems to be 

 a bigger factor in deciding when we prune than anything else — 

 whether it is feasible to get at the work. 



Pres. Yeaton : Now, another question that was handed in 

 early this morning is No. 3 on the question list : Is there any 

 successful treatment known as yet for the Baldwin spot? I 

 will ask Dr. Morse to answer it. 



Dr. Morse : Not that I know of, personally. 



Pres. Yeaton : What has been tried as a remedy for that, 

 that vou know of ? 



Dr. Morse : Professor Fraser can perhaps answer that bet- 

 ter than I. We have had a vague notion that the development 

 of Baldwin spot has something to do with the nutrition of the 

 tree. This is very vague, for no one seems to be able to tell 

 exactly what conditions need correcting. It has also been 

 claimed that storage conditions are partly responsible for its 

 development on the fruit. 



Certain evidence was brought out by Professor Brooks in 

 New Hampshire, which showed that there, at least, another 

 apple fruit spot has been mistaken for Baldwin spot. This 

 trouble I am inclined to think, from what I have learned by 

 observation and from talking with others, particularly at this 

 meeting, has been rather common in Maine during the past 

 season and may have been confused with the true Baldwin 

 spot. This other fruit spot is caused by a fungus which it was 

 shown in New Hampshire could be controlled by spraying. 

 Brooks maintains that it is due to the confusion of the two 

 troubles which led to the earlier reports of controlling Bald- 

 win spot by spraying. 



Some experiences which have been related to me here at 

 this meeting indicate that in some instances the spot which 

 has been troublesome this season has been controlled by spray- 

 ing. Wilson Conant has, I think, mentioned some such cases 

 as coming under his observation, and Mr. Robinson has also 

 reported similar observations to me. Therefore, I am inclined 

 to think that in many cases it is the other fruit spot, the fun-
