Looking dowa the alley between the first and second sets of cooling ovens 

 on the shore of Lake Cadillac, Cadillac, Mich. After cooling for 24 hours in 

 the ovens to the right, the trucks of charcoal are pulled by means of a cable 

 into the cooling ovens on the left. Each cooling oven is 52 feet in length and 

 holds four trucks at one charge. Note the standard gauge tracks between 

 the cooling ovens and the manner in which the dirt is piled around the base 

 of the cooling ovens to keep them air tight.
