(Sec. 20.) 

 SECTION IN A R. K. CUT NEAR CALHOUN STATION. 



In No. 1, a very large skeleton of Zeuglodon, (remnants of which are still 

 abundant in the pile thrown out of the cut), was found, but unfortunately, its 

 portions were scattered all over the country. Here also, the stratification lines 

 are not very distinct, and the thickness of the Zeuglodon stratum, especially, 

 varies greatly. At Rev. J. R. Lambuth's, about 2 miles E. of the cut, this 

 stratum, struck in a cistern, was found only 18 inches in thickness. — It is 

 chiefly stratum No. 2 of this section, which causes the troublesome caving 

 of the sides of this cut. 



204. The banks of Pearl River, and the hills bordering the bottom, do not ex- 

 hibit any outcrops in this region, nor are these very common until within a few 

 miles (N.)of Jackson, where strata closely resembling the matrix of the Zeuglo- 

 don at the cut (Sec. 2G), appear in washes on the roadside ; containing large- 

 numbers of the oyster before mentioned, but only traces of other fossils. The 

 same material is found outcropping near the Lunatic Asylum, about % mile N. 

 of the State House. 



The following general section, deduced from observations at Moody's branch 

 and in the McNutt Hills, 1 to 2 miles N. E. of Jackson, will best illustrate the 

 condition of things in this neighborhood.
