gous fruit spot which has been troublesome this year. I do 

 not personally know of a method of controlling true Baldwin 

 spot. 



Pres. Yeaton : In your opinion, Doctor, what has caused 

 those red spots on the apples this year where there is no indi- 

 cation of Baldwin spot or a fungous condition, where it is 

 merely in the skin and had not penetrated into the pulp? 



Dr. Morse : Why, from my standpoint I feel positive that 

 this is not due to a fungous parasite. Dr. Patch and I have 

 taken up the matter and discussed it between ourselves, and 

 she inclined to think that this resulted from some insect attack 

 when the apples were smaller. She has also stated to me that 

 she has seen a number of apples spotted in this manner, where 

 it was plainly due to heavy infestations of oyster shell scale 

 on the fruit, but where the insects had disappeared from the 

 surface before the fruit came under observation. In some 

 cases which she and I examined, there is considerable reason 

 to think it may be the apple seed chalcid. We find oftentimes 

 in those apples that the seeds are abortive. I have no doubt 

 that Professor Eraser knows more about the work of that 

 insect than I do, for I have never seen it before. 



Question : May I ask Mr. Gilbert whether they propose to 

 publish any data as to what is the optimum and maximum 

 supply to feed to any special market? Are you tabulating it 

 with that idea? 



Mr. Gilbert: Not exactly. We hope, after we have these 

 investigations in which we tabulate every day the supply which 

 arrives in the market during the principal part of the shipping 

 season, to tabulate some features which will have a bearing at 

 least toward the discovery of what the market can actually 

 consume. But you must realize that there are many factors 

 which enter into consumption figures. There are times when a 

 slight turn in the weather will cut down the buying of any 

 commodity from 50 per cent to 75 per cent. The arrival of 

 another crop of fruit, on the market, although the crop in 

 question may be of good quality and a sufficient supply, may 

 cut down the consumption of that first variety very largely. 

 There are so many factors which influence that, and they 

 change from year to year so greatly that it is going to be 

 difficult to put out any figures to show exactly how many bar-
