100 Expedition to the 



ferry boat used at Arrow Rock is one peculiarly adapted to 

 the navigation of a rapid stream. It consists of two canoes, 

 on which rests a platform, with a slight railing to prevent 

 cattle from falling off. 



Arrow Rock is so called from its having been formerly re- 

 sorted to, by the neighbouring Indians, for the stone used to 

 point their arrows. It is a beautiful situation, and rises to 

 considerable elevation above the water. From its summit 

 is a pleasing view of the river, and near the base is a re- 

 markable eddy, which, as they were crossing, whirled their 

 ferry boat entirely round. On the second day they left their 

 encampment at an early hour, and travelled forward through 

 plains, where very few trees were to be seen. They turned 

 off from the Osage trace, in which they had been travelling, 

 and went eight miles to visit the salt works, and some re- 

 markable diggings, on the saline fork of the Le Mine. Here, 

 at one establishment, one hundred bushels of salt are manu- 

 factured per week; eight men are employed, and one hun- 

 dred and eighty gallons of water are evaporated to produce 

 a bushel of salt. 



Two miles fromjthe confluence of the Camp Fork with the 

 Saline, are the salt works, and the residence of Mr. Lock- 

 hart, who received the detachment with much hospitality. 



His works were not then in operation, but were sufficient- 

 ly extensive for the manufacture of five hundred bushels of 

 salt per week. Near his house, are the diggings so often 

 mentioned in this region as objects of curiosity. These 

 are irregular, but very numerous excavations of little depth, 

 but evidently the result of the united labours of many per- 

 sons, who were possessed of instruments of iron and steel, 

 as no others could have penetrated, and removed the com- 

 pact rocky soil, of which the points and brows of the hills are 

 composed. These excavations occur frequently in an extent 

 of two or three miles; and from the amount of labour, which 

 appears to have been expended on them, it has been thought
