portation, but they are now known to be caused by packing the 

 peaches so closely that the air does not have full access to all the 

 fruit. The respiration of the cells at the points of contact is in 

 consequence interfered with, and these cells are suffocated and 

 die. 



One sometimes finds large potatoes that are hollow in the 

 center, the cells lining the interior colored brown or black. 

 Otherwise the potatoes are sound. This also is a respiration 

 injury. While the tuber was in the soil or after it had been placed 

 in storage, the outer layers of tissue used all the available oxygen, 

 and the innermost tissue died, leaving a hollow. Cellars, pits, 

 and storage houses for fruits and vegetables must be carefully 

 ventilated. 



Ships with specially ventilated holds are used in importing 

 bulbs from Holland and fruits from the tropics. The building of 

 ventilated holds came as a result of the death through suffocation 

 of several men who attempted to unload a cargo of bulbs from an 

 unventilated ship bottom.
