REFRIGERATION OF DEESSED POULTRY IN TRANSIT.

part of the year. Because of the fact that this class of goods is ad- 
mittedly extremely perishable, the railroads have endeavored to per- 
fect its transportation, but, lacking definite information concerning 
either the detriment or the benefit of present equipment and practices, 
the advances have of necessity been slow. 
Temperatures for dressed poultry. — The experiments indicate that 
less than 31° F. is the most satisfactory temperature of dressed 
poultry for long hauls. It will be seen, by referring to figure 2, that

a 10-degree rise in the temperature of the car during the haul makes a 
difference in keeping time of at least five days on the New York mar- 
ket when the market environment is favorable. Such an observation 
is worthy of the serious attention of shippers, receivers, and carriers, 
since all feel the depression that ultimately results from putting poor 
goods on the market. More far-reaching, however, is the further 
observation, pictured in figure 3, that even such excellently handled 
poultry as comprised these experimental shipments, if exposed to
