This continuation of the line of wells passes into a much 
better section of country and the waters show it in the less 
amount of total solids and nitric nitrogen. We were at first 
surprised to find so much nitric nitrogen in the Nebergall well- 
water, but a subsequent visit and examination of tlie soil con- 
ditions revealed the fact that the soil carried fairly large 
amounts of nitric nitrogen, sufficient, in spots, to interfere with 
vegetation. The same is the case with those marked H. O. 
Roller and Geo. GummiiiPS. Tlie soil for instance at the Roller 
place showed in a general sample re])resenting 40 acres, 5:?. 8 
p.p.m. nitric nitrogen, whereas the 40 acres immediately north 
of it showed onlv 0.1 i).p.m. The Gumming’s 40showed 50.7 ]).}). m. 
and the 40 immediately south showed 0.8. These are as clear 
instances of the intimate relation between the character of the 
well-waters and the surface conditions as our data reveal. 
Others show larger amounts in both soil and ground- waters and 
involve larger areas but none are clearer than these. These 
remarks, however, are really in antici]iation of data to be pre- 
sented. 
WELL-WATERS ALONG ROAD JUST EAST OF WELLINGTON 
The next line of wells runs just east of Wellington and for 
nearly the same distance between 11 and 12 miles from north 
to south.
