REPORT OF CRANBERRY SUBSTATION FOR 1915. 21 



4. Two lots, each consisting of six, 1-quart cans of Late Howe berries, 

 none of which showed any decay, were placed in storage on the ISth of 

 January. The berries of both lots came originally from the same source. 

 Those of the first lot, having been run through a Hayden separator only 

 once, were taken from the first separator box (the "good" box). Those of 

 the second lot, having been run through the separator once, were then 

 taken from the first box and put through the machine a second time and 

 caught in a box held close up to the spout of the separator in place of the 

 separator barrels. This fruit was examined February 18, 12 per cent, of 

 the berries in the first lot being found to be wholly or partly rotten, as 

 compared with 23.44 per cent, of those in the second lot. It thus appears 

 that the second machining of the second lot of berries caused an increase 

 of about 95 per cent, in their tendency to decay. 



5. Enough boxes of Late Howe berries from the same source were 

 run through a Hayden separator on January 19 to fiU both of the separator 

 barrels. Nine tin 1-quart cans were filled with berries from the top of 

 each of these barrels and placed in storage. Two-thirds of the fruit left 

 in the barrels were then dipped out carefully, and nine more cans were 

 filled with berries from the bottom portion of each barrel and stored for 

 comparison with the other eighteen. None of the berries put into any 

 of these cans showed any rot when they were placed in storage. They 

 were taken out of storage and examined ori February 19, the results 

 obtained being shown in detail in the following table : — 



Table 13. — Injury to Keeping Quality of Cranberries caused by their 



Drop in Barrels. 



As will be seen by the above table, the rot development among the 

 berries from the bottom part of the separator barrels, as compared with 

 that in the fruit from the top part, showed that the injury due to the drop 

 in the barrel had increased the tendency to rot about 56 per cent. 



ii) To determine the General Rate oj Temperature Changes among Barreled 

 and Crated Cranberries. — The two following tests were conducted in 

 this connection : —
