Simple method of determining absorption capa- cities of different soils under different conditions. The study "vms made by Mr. John '-Auten, Silvicul- turist of the Station. A pail with the bottom cut ' out is placed on the site to be examined Vvdth all the leaf litter taken av/ay. Outside bottom edges of pail are packed to prevent leakage. Pail filled v/ith v/ater. Absorption powers of soil based on it takes for to seep out of pail into ground, A simple test but effective. 2, TiTater seeps into forest soils 100 times faster than into soils on abandoned fields. 3» VJater seeps into unburned and protected forest soils 15 times-: faster. than into the soils of forests burned over annually, ' : - i--^ ^ ' , ... 4, Five years of protection will increase absorptive pov/ers of' forest soils formerly burned over annually three times. This fact is important in our erosion, waterphed> and forested areas. It means that soil fertility can be increased tremendously on burned over forests merely by adapting fire protection. On watersheds and areas subject to erosion, it is possible to reduce the -amount of erosion merely by giving the vrooded area protection, 5, ¥ir, R. C, Hall, entomologist at the Station, who has, been studying burning from, the settlers viev^^point, has been unable to find any other entomologist who v/ill recommend burning, as a means of getting-rid of the , cattle ticks, and chiggers. The importance of this state- ment is best realized when one considers that the majority of the burn- ing done in the southern states in this region is to get rid of these pests# ⢠6, It is
