Singular Salt Depository

-An officer ofthe ü. S. Dragoons, writirjg frorn Wachita i iver, Aog-. 5th gi vos the following statement of the Sak Plain of the prairies, which we copy from the Cincinnati Gazette: 'Aböut 200 miles from Fort Gibson we came lO the Great Salt plain. This was one objecl of our journey, and the sight was truly gra. ir ying. The bed of the rjver was widened, beiug near 6 miles in vidth,and two in length; the river running by one side of it, tlirough a smal! channel in the eand, while this upper plain thröughout was covered by a ernst of -salt ers white as snow. We approached it through sand hills and when within 4 or 5 miles of it, tbe plain looked like an immense s&itLike which had dried upand left tbe salt in its bed. We found the sak to have a local origin; it come? to the liver ín a creek which is very salt. This overflows the plain nnd leaves the water to chryslalize on the surface. Heavy rains will wash the ea!t away; but the overflow from the creek comes at the same time to bring more salt water for chryaalaiion. At thiapoint we first began tofindBuffalo. Within twd döys journey of ihe Great Salt PJain we carne to the Salt Rock, at it is callcd. We found it to be in the bed of the Semirone, c stream south of the ono the Great Plain is on, nud is an immense spring of salt water rising at the base of a high clay hill and boils up over n space of 160, chry$!alizing aa fnst as it reaches the surf ce forming a rock of salt all over the cove so hard thot we broke one mattock in vain attempts to get a masa of it. The holes where the water comes out are lined with salt as far down as the arm could reach.
