r End view of a pair of cooling ovens showing the character of the door, lugs 

 and method of heaping dirt around the base to prevent the entrance of air. 

 The trucks loaded with the heated charcoal are drawn directly from the oven- 

 house into the first cooling oven and left there for 24_hours. They are then drawn 

 into the second cooling oven for another 24 hours. After that, the charcoal 

 stands in the trucks in the open air for 48 hours, after which it is loaded on the 

 freight cars where it remains 12 hours before it is sent off to its destination. 

 I These cooling ovens are kept air tight to prevent combustion of the heated 

 charcoal.
