iced car for ten days, were inspected once 
on withdrawal and one or two weeks 
after withdrawal. The following table 
eives the data on fifteen series of com- 
mercially handled fruit, both precooled 
and non-precooled held in the iced car. 
On withdrawal there was about three 
times more decay in the non-precooled 
than in the precooled.

While the differences are not so strik¬ 
ing one or two weeks later, nevertheless 
they are consistent. There was little or 
no stem-end decay on withdrawal, but 
one week later, the precooled showed 4.1 
per cent as compared with 10.8 in the 
non-precooled. Two later there is also a 
consistent difference. It is interesting, 
therefore, to compare the total decay in 
the precooled and the non-precooled lots, 
that is, (the total of stem-end and blue 
mold decay. On withdrawal there was 
three times mlore decay in the non-pre¬ 
cooled than in the precooled. One week 
later the non-precooled showed almost 
twice as much decay as 'the precooled. 
Two weeks later the differences are not 
so great but consistent. At the time of 
arrival the fruit usually shows little or 
no stempend decay. However, at the 
end of one week there is a considerable 
development of this trouble and the effect 
of precooling is here most pronounced. 
The following itable gives the results of 
an average of 14 shipments during De¬ 
cember and January, seven of these be¬ 
ing precooled and shipped under half ice, 
the other seven under ventilation only.

While this is hardly a fair comparison, 
it does bring out rather strikingly the 
effect of temperature and quick cooling as 
regards decay and deterioration in tran¬ 
sit. The effect of temperature on the 
development of stemj-end decay is here 
even more striking than in the holding 
lots. In the fruit under ordinary venti¬ 
lation there is 9.8 per cent after one week
