Measurements on a sample acre taken in a virgin tupelo-cypress 

 slough and representing the better stands of this association are shown 

 below. The 51 trees 12 inches and up in diameter on this acre were 

 buttressed so that the diameter measurement was taken at 7 feet instead 

 of 4J4 feet from the ground. The tupelo gum grows very slowly and 

 many of the larger trees were three centuries old. 



A sample acre taken in virgin bottomland forest gave the following 

 data on the association of trees which is common between the slough and 

 the well-drained benches.
