nificant points into consideration, such as its doubtful 
fuel value, and its limited quantity, there are good busi- 
ness reasons why at present and for a long time in the 
future, the lignites of Dakota County, Nebraska, may be 
considered as of no commercial value as a general fuel 
supply. 
As to their future possibilities, there are certain sug: 
gestions which offer a field for many more pages of dis- 
cussion for which there is no place here, and only by con- 
siderable study can the rationality of such suggestions be 
assured. It has already been pointed out that Dakota 
County is well situated for manufacturing and distrib- 
uting purposes, and the lignite localities are shown to be 
easily accessible by railroad spurs. One suggestion is 
the possibility, at some future time when economic con- 
ditions demand it, of using the lignite in the manufacture 
of briquettes. Another is that the bed of fire clay might 
be mined in connection with the lignite, the latter being 
used on the spot to burn fire brick from the clay. It 
might thus be used directly as a fuel or converted into 
fuel gas. Likewise it might prove a suitable fuel for 
a nearby cement plant. 
Some of the sands of the Cretaceous are perhaps 
well adapted for the manufacture of glass. A gaseous 
fuel is best adapted to such an industry. 
Thus there are qualities possessed by the lignite 
which, by virtue of its location and associated deposits, 
suggest the possibility of great industrial development in. 
the immediate vicinity of its occurrence.
