The precooled, carefully handled berries showed practically no 

 decay on withdrawal after four, six, and eight days in the car, ex- 

 cept 1 per cent after four days. This is an apparent discrepancy, 

 but it is easily accounted for when one considers that it is impossi- 

 ble to use the same lots for inspection more than once. The non- 

 precooled berries showed no decay at the first withdrawal, 0.2 per 

 cent of decajr at the second, and 4.8 per cent of decay at the end of

the 8-day period. The after- withdrawal inspections, after the fruit 

 had been held on the market for one day, are even more striking 

 and instructive. The first market-holding inspection of the pre- 

 cooled fruit showed it to be apparently sound, while at the second in- 

 spection there had developed 12.6 per cent of decay and at the third 

 inspection there was found 18.6 per cent of decay. While there was 

 little difference between the precooled and nonprecooled fruit at the 

 withdrawal inspections, there was quite a marked difference in favor 

 of the precooled berries in the market -holding inspections. The non- 

 precooled fruit apparently was somewhat riper, having ripened or 

 matured more rapidly under the higher temperatures in the cars
