Nitrogen Fixation ii 
The nitrates equalled 1.016 per cent of the air dried soil. 
Sometimes there is an incrustation, it may be light or heavy, 
and underneath this there is a mealy mass of soil particles and 
minute crystals. At other times the surface soil itself is mealy, a 
peculiar condition which is often expressed by likening the soil to 
ashes, not always an apt comparison but sometimes an exact descrip¬ 
tion of the condition, especially if the soil is very dry. A sample 
of mealy soil was taken from this orchard. The soil was slightly 
incrusted without efflorescence and was mealy beneath the thin 
crust. The sample was taken to a depth of four inches. The 
water soluble equalled 5.372 per cent of the air dried soil. The 
residue was quite deliquescent and smelled acid when dried at no° 
for 1 and 3-4 hours.
