Table 8. — Effect of Water Storage on the Keeping of Dill Cranberries 

 of Differ'^nt Degrees of Ripeness. Period of Storage, September 29 to 

 November 22. 



6. The Relative Keeping of Graded and Ungraded Cranberries. 



Table 9 describes five experiments in this connection. In each of these 

 the two lots of fruit were obtained by dividing the contents of picking 

 crates by alternate dipping with a quart measure. Only berries coming 

 from the separator spout were used, those going into the boxes of the 

 machine not being included. The spacing of the grader was fifteen 

 thirty-seconds of an inch. A board seven-sixteenths of an inch thick was 

 in the grader frame in place of the grader when the second lot of each 

 test was run through the machine. Further information about the tests 

 follows: — 



Test 1. — All this fruit was picked on September 20 in the same loca- 

 tion on the station bog. Both lots were put through a Hayden separator 

 October 2, and run into boxes placed close up to the separator spouts 

 instead of barrels. The grader took out about 30 per cent of the quantity 

 of fruit in the first lot. Both lots were screened October 6, and run from 

 the screens into bushel picking crates, all of which were of the same size 

 and construction, and were placed close up to the mouths of the screen. 

 The screeners were exchanged between the two screens when the two lots 

 were about half looked over, so as to have the cleaning of the lots as 

 uniform as possible. The crates were left open during the storage, four 

 crates of the graded and five of the ungraded fruit being used. 



Test 2. — All this fruit was gathered in the same place on the station 

 bog on September 27. On October 25 both lots were put through a sepa- 

 rator, being run from the spouts of the machine into boxes placed close 

 up to them. The grader took out about 30 per cent of the first lot. When 

 the fruit was screened, October 26, both lots were run into barrels from 

 the mouths of the screen as usual, no easers ^ being used. The writer 



I "Easer" is a term applied to any device for preventing the bruising of berries by breaking 

 their fall.
