by the diagram is the much smaller amount of soft-rot in the pre- 

 cooled than in the nonprecooled lot. In the celery stored for two 

 weeks there was an average of 7 per cent of soft-rot in the precooled 

 and 19.6 per cent in the nonprecooled, nearly three times as much 

 in the latter case. At the end of four weeks the soft-rot in the pre- 

 cooled had more than doubled, but there was still twice as much in 

 the nonprecooled celery. The amount of heart-rot also showed a 

 consistent difference in favor of the precooled. The increase of

 and at the end of four weeks in storage at 32° F. in both precooled and nonprecooled celery shipped from 

 Manatee, Fla., to New York, season of 1915.

 two weeks to 13.4 per cent at the end of four weeks clearly shows 

 that the trouble will develop in storage.

1 In some cases both soft-rot and heart-rot were found in the same plant, but were recorded separately. 

 Total decay refers to plants showing either or both forms. 



Table XI and figure 18 show the various degrees of soft-rot at the 

 different inspections. Celery was classified as having slight soft- 

 rot if the decay was confined to not more than two or three stalks 

 and bad soft-rot if the bunch showed considerable decay but still 

 had a marketable "heart." " Complete soft-rot" was the term 

 applied to the celery that was so badly decayed as to be rendered 

 worthless. The diagram (fig. 18) shows that practically all the bad 

 and complete soft-rot in the precooled celery was so slight as to
