usually made it easy to distinguish the precooled from the non- 

 precooled lots. The heads in the precooled hampers were usually 

 level with the top of the hampers upon arrival at the market, while 

 those in comparable nonprecooled hampers, because of shriveling 

 and general decay, usually had sunk several inches below the top. 



HOLDING LOTS. 



The results of the inspection of sixteen experimental lots held in 

 the refrigerator car at Palmetto are given in Tables III and IV and 

 are shown in figures 8 and 9, respectively.

Fig. 8.— Diagram illustrating the percentages of prime, marketable, and worthless lettuce upon with- 

 drawal from the car and three days later in precooled and in nonprecooled commercially cut and carefully 

 cut lettuce held at Palmetto, Fla., season of 1913-14. 



At the first inspection of the experimental lots held in Palmetto, 

 one half of the lettuce in each basket was removed and inspected, 

 the lower half being left undisturbed. The inspected half was then 

 repacked and the whole basket held until three days later, when 

 the two halves were inspected and recorded separately under the 

 headings "Repacked" and "Undisturbed." This was done in order 

 to learn what effect removal from the basket and handling while 

 on the market had upon the lettuce. As is brought out in Table 

 III, there is very little difference in the effect of the two methods, 

 such difference as there is favoring the' lettuce that was removed 

 and repacked. Apparently moderate handling has little or no
