( Owing to the fact that the roads are not opened in the east 
and west direction straight through as they are from north to 
south, we have been compelled to be satisfied with partial sec- 
j tions of the country. The first series of this sort that I shall 
: give is one on a line north of the preceding and the furthest 
north of any taken. The road is not opened either to the north 
; or east from the Kent place.

*This well is one mile south of this east and west line and is in lower 
ground. It is included here because there is no well on our line in this section 
of land. 
If we reject the well on the Piatt place, we see that this line 
shows in Sec. 15 a decidedly unusual amount of nitric nitrogen, 
whereas no other well in this line does so. In this work we have 
at no time attempted to consider, either in water or soils, such 
amounts of nitric nitrogen as it is usual to find. We have at- 
tempted to account only for what may be considered unusual 
quantities, .and that within such wide limits that there can be 
’ no question about the amount present being very high. The 
first 3 wells given in this table are in Sec. 14 and show 0.8, 4.0 
and 3.5 p.p.m. of nitric nitrogen. These normally small amounts 
I are, I think, universally considered to be derived from the oxi- 
dation of soil nitrogen without consideration of the agency. 
I My thesis is that this applies to the larger quantities as well 
as to the smaller. There is only one well in Sec. 15 with 56 
p.p.m. of nitric nitrogen. In a well just across the line in Sec. 
22 we find 191.0 p.p.m. of nitric nitrogen. 
' The next east and west line of wells that I shall give is a 
short one, 3% miles south of our first line and 2 miles south of 
Wellington. This line begins at the first north and south line 
given, and extends westward 3% miles. The ground-waters at 
the beginning of this line are extremely bad. The land tra-
