200 GEOLOGICAL RECONNOISSANCE 
lated after you have learnt more of the other localities of interest. When 
in Conway county, examine the state salt spring. There are also several 
other localities of interest in this county, on the Cadron, and, perhaps 
also, on Cedar creek, a branch of that stream, which may require your 
attention. When in the north-east part of this county, you will pass over 
a few miles into White county, and examine a locality of coal, of which 
Ihave previously given you a note and directions how to findit. The 
rest of this county has already been explored. 
Ascertain where the coal measures of Conway county terminate, and 
the metamorphic slate formation of Pulaski county commences, in your 
easterly route into Pulaski. Itis, probably, somewhere near Palarm bayou. 
Some gold ore is said to have been found somewhere near that stream. 
One of the most important localities to be examined in Pulaski, is the 
Kellogg mine of argentiferous galena, some ten miles north of Little 
Rock, on Kellogg’s creek. 
As I have been over the road from Little Rock to Oakland Grove, in 
White county, it will not be necessary for you to pass over that ground 
again at present, unless you hear of something special that may require 
your attention. 
I know of nothing particular at present to which I can direct your 
attention, while passing through Prairie county into Monroe, where your 
geological reconnoissance will terminate for this season; but you will take 
every opportunity to inquire, before you enter a county, what there may 
be in it of particular geological interest, and direct your course accord- 
ingly. 
In each county which you pass through, you will collect sets of charac- 
teristic soils, upon the same plan as heretofore followed by the geological 
corps of Arkansas.
