REPORT OF CRANBERRY SUBSTATION FOR 1916. 201 



The records in Table 7 show that as a rule the temperature of berries 

 left in crates on the bog exposed to the sun for several hours did not change 

 more than 3 degrees. The temperatures of some of these crates were taken 

 every thirty minutes from the time they were picked until they were 

 housed, almost no variation being discovered until very near the latter 

 time. The averages of percentages given in the table indicate that the 

 Early Black berries housed at once kept somewhat better than those left 

 on the bog, whereas these results with the Howes fruit were reversed. This 

 difference in the storage of the two varieties corresponded with the differ- 

 ence in the average temperatures of the different lots when housed, the 

 Early Black berries housed at once averaging to have lower temperatures 

 when placed in storage than did those left on the bog, whereas the Howes 

 fruit housed at once had a somewhat higher average temperature when 

 stored than did that left on the bog. 



The four other experiments under this head were carried out in connec- 

 tion with some of the tests of the effect of wetness on cranberry keeping 

 described below (No. 6 (a), page 201), Table 10 exhibiting their arrange- 

 ment and results. As in the first four series of tests, Dr. Stevens took all 

 the temperatures with chemical thermometers at the centers of the crates. 

 It was partly cloudy all day the day that the Early Black berries used in 

 these tests were picked. The averages of percentages in the table show 

 that with both varieties the wet berries kept better after having been left 

 on the bog, whereas the dry ones kept better when housed at once. 



On the whole, the results of these tests were inconclusive, though they 

 failed to show much harm to the keeping quahty resulting from leaving 

 the crated fruit on the bog for several hours under ordinary harvesting and 

 storage conditions. 



6. Wet and Dry Cranberries compared as to Keeping. — Three series of 

 tests come under this head, as follows: — 



(a) An area 60 feet square laid out on Early Black vines on the station 

 bog was divided into equal parts by lines running diagonally between the 

 corners. Two of the opposite triangles thus formed were scooped while the 

 berries were wet with dew, the other two being left until they were dry. 

 The ways in which these berries were tested and the results obtained are 

 shown in test No. 1 of Table 10. 



(b) An area 100 by 30 feet laid out on Howes vines on the station bog 

 was divided into triangles by diagonal lines between the corners. Two 

 opposite triangles were picked with scoops while the vines were more or 

 less wet with dew, and the other two when they were dry. The manner of 

 testing this fruit and the results obtained with it are shown in test No. 2 

 of Table 10.
