The next soil g-iven was collected along the edge and from 
a corner of a field that was still in fair condition. The surface 
of the soil showed all the characteristics of land affected bj" 
nitre-trouble. The water-soluble was not quite so high as in 
the preceding case, and the condition of the land at the time 
the sample was taken was not very bad,

The third sample of soil was taken in a beet field and from 
the spaces between the rows. The beet tops were very large 
and very green. The stand was somewhat irregular, but it was 
a surprise to find so good a one under the conditions. One would 
scarcely think that the seed would germinate in such soil. The 
soil was black but not so wet as it appeared. We dug a hole 
at the edge of this field to get a sample of the ground-water. 
The water came in at a depth of 4 feet and below this it did 
not seem to come in at all. The hole was in all a little more 
than 5 feet deep. We had to wait an hour for the water to run 
in before we could get a five gallon sample. 
The analysis of this soil extract gave us an unusual amount 
of trouble. The analysis was repeated three times with fair 
agreement and yet we have an excess of bases. The analyses, 
were made on the aqueous extract without concentration.
