Use of these small temperature differences between the inside of the coil 

 and the room will reduce the Btu capacity of the coil to about 307, of what most 

 colls are designed for. This should be of no serious consequence, since the 

 maximum cooling load on the coil is during loading and initial cooling. The 

 change in low side cutout recommended above would take place after this peak 

 load has passed. 



One possible complication might result in a situation where one compressor 

 was used simultaneously on a 37°F CA room and on a 32°F cold storage where lower 

 low side pressures corresponding to a coil temperature perhaps below 32°? would 

 be required. In this case, a back pressure regulating valve would be required 

 on the low side line from the coil in the CA room.

POMOLOGICAL PARAGRAPH 

 Report Storage Holdings Promptly 



At a recent meeting of the Marketing Committee of the Massachusetts Fruit 

 Growers Association, growers complained about the delays in learning about prices 

 and storage holdings. Warren Clapp, who was present, explained that a few 

 growers are consistently slow in making their reports. The Marketing Committee 

 urges these few growers to improve their reporting. There is no need to use up 

 public funds that we need elsewhere for follow up phone calls and most important 

 it is unfair to delay information reaching your fellow growers. 



Our only salvation in fruit growing is in working together to do a better 

 job. Remember if you hold your information for a phone call, you are costing us 

 all money and loss of time.

SCALD CONTROL FOR 1963 



Scald control for our varieties is not simply a question of what chemical to 

 apply. Scald varies tremendously with variety (sometimes between strains of a 

 variety), the type of growing season experienced, maturity of the fruit when 

 harvested, period of time from harvest to storage, how it is stored (regular cold 

 or CA) and how long it is to be stored. Because of the importance of the above 

 factors in the development of scald the blanket use of Stop-Scald (ethoxyquin) or 

 CPA (diphenylamine) on all stored apples is not warranted. In addition, neither
