The chemical analysis of this lignite, has not yet been undertaken, but 
will be made hereafter.* 
Its appearance, however, hardly justifies the expectation that it will be 
found sufficiently rich in carbon and hydro-carbons, to be valuable as a 
fuel, even if the deposit should prove to be extensive. Lignite of a similar 
character occurs seven miles a little west of south form the above locality, 
on the Beech Fork of Cache; also, one mile north, two miles north, and 
four miles south. 
If it be a continuous bed between all the different out-crops known at 
present, it would occupy an area of some seventy square miles, but this is 
by no means certain, since these lignite beds are often quite partial and 
local. Future detailed examinations in Greene county may throw farther 
light on its extent. 
It is worthy of remark, that there occurs disseminated in this lignite a 
yellow pyrites, which contains a small per centage of copper, the exact 
amount of which will be reported on, as soon as the chemical analysis 
shall be completed. 
‘wo miles from Gainesville, near Jones’, the quaternary sand is indu- 
rated into a soft sandstone, which is used in the construction of chimneys. 
It contains impressions of leaves, one of which appears to belong to the 
magnolias, and others to some species of water-oak, or willows. When 
these have been more fully investigated, and more extensive collections 
made from other localities, we shall then be better able to report in 
specific detail. 
About two-thirds of the flat Cache lands are “black sand lands,” and 
one-third post-oak lands. The latter are too wet for cultivation, without 
a complete system of drainage. The highest of the former are cultivated, 
and are very productive. Hereafter, if the agricultural department of 
the survey be provided for, we hope to be able to supply comparative 
chemical analyses of these soils, which will give more insight into their 
relative productiveness, than we are able to supply in their absence. 
If the flat post-oak lands of the Cache country of Arkansas, could be 
drained, and subsequently cultivated with profit, it would greatly increase 
the agricultural resources of Greene, Randolph, and Independence counties, 
and contribute materially to the settlement of this part of the state. 
Near David Schultz’s place, on the east or St. Francis side of the 
Crowley ridge,and about 2 miles from the St. Francis bottom, near the 
line between townships 18 and 19 north, range 8 east, there is a deposit 
of yellow ochre, similar to that previously described as occurring at the 
«“ Pine,” on the other side of this ridge.*
