REPORT OF THE CRANBERRY SUBSTATION. 123 



These results strongly confirm those previously reported.^ It was 

 noticed that a large percentage of the rot spots shown by berries with 

 which leaves were mixed were quite small. 



9. The Effect of an Admixture of Decayed Early Black Cranberries on 



the Keeping of Berries of that Variety. 

 Two lots of berries in quart cans were used in this test. There were IS 

 cans in each lot. The berries were examined and put in storage during 

 the days of October 18 to 23. The decayed berries put in lot 2 were 

 entirely soft but unbroken. The can covers were tight but not sealed. 

 Lot 1 contained 9,105 sound berries, and lot 2, 4,957 sound berries mixed 

 with 5,541 rotten ones. On December 28 the beraes were examined. 

 Lot 1 contained 3,823, and lot 2, 1,159, sound berries. The percentages 

 of berries found to have wholly or partly softened during the storage were 

 as follows: lot 1, 58.01; lot 2, 76.62. The admixture of rotten fruit appar- 

 ently promoted decay among the sound berries; but this result contra- 

 dicts a like test with Howes fruit previously reported.- 



10. Berries separated with Hayden and ivith White Machines compared 



as to Keeping Quality. 

 Boxes of fruit from a commercial lot of Howes berries were divided by 

 dumping, and one part was cleaned with a Hayden and the other part 

 with a 'Wliite separator on November 12. The fruit from each machine 

 was packed in a half-barrel and shipped to New York. It was examined 

 there December 12, 20.9 per cent of that cleaned with the Hayden sepa- 

 rator and 21.8 per cent of that cleaned with the White then showing 

 decay. This result accords with that of like tests heretofore reported^ in 

 showing little difference in the injury caused by the two kinds of sepa- 

 rators. 



11. Barrels v. Crates as Containers for shipping Cranberries. 

 The two following shipping tests were conducted : — 

 (a) New York Shipment. — This fruit was gathered on one of Dr. 

 Rogers' bogs on October 3 and kept in picking crates, just as it came 

 from the bog, in the basement of the station screenhouse until November 

 16, when the contents of the crates were divided into two lots by alternate 

 dipping with a quart measure. Both lots were put through a Hayden 

 separator November 17, picking crates being placed close up to the sepa- 

 rator spouts to receive the berries, instead of barrels. Only the fruit 

 coming from the spouts of the separator was used on either side of the 

 test. A grader with a thirteen-thirty-second-inch spacing was used with 

 both lots. The berries were screened November 17, easers being used 

 with those that were barreled, while Beaton crates were placed close to.
