plots every ten chains (660 feet). 



On each sample plot the diameter and height of 

 each tree was measured, borings taken to determine 

 rate of growth, the forest type and site recorded, 

 amount and kind of young growth, incidence of disease 

 and evidence of mortality listed. From the data ob 

 tained in this way maps of the forest land area were 

 prepared, together with figures on the area of forest 

 land in each type and site quality and all pertinent 

 data respecting present and prospective conditions 

 of the forests. 



In some respects the South presented the most 

 trying conditions for the crews summer heat and 

 humidity, chiggers, snakes, and in the great hard 

 wood areas in the Mississippi Delta, poison ivy and 

 the innumerable bayous to cross. Where bridges or 

 boats were lacking, the crews would wade or swim 

 across the bayous with their equipment floated on 

 small rafts, or carried above water, always won 

 dering when some water moccasin might drop out of 

 an overhanging tree on or near them. 



In the Pacific Northwest we started in the 

 Douglas fir forests of the west side of the Cascades.
