XII. Twenty-one feet of exceedingly coarse green sandstone weathering 

 into brown slabs. 



XIII. Twelve feet of clayey sandstone. 



XIV. Forty-eight feet of sandstone, fine, hard, and green. Of all the strata 

 examined this was the most remarkable for the quantity, variety, and excellent 

 state of preservation of the fossils it contained. From it were taken several fine 

 heads and almost an entire skeleton of Loxolophodon, a great number of leg and 

 foot bones, jaws, teeth, and vertebras. Just at the place where the section was 

 made the face of the bed was very steep, and from it, twenty feet above the 

 plain, projected the distal end of a femur. The bone measured some thirteen 

 inches across the exposed end, and, when cut out of the rock, was found to be 

 four feet in length. A little further to the east in the same stratum lay a thick 

 bed of Unios, while turtles, pieces of crocodile jaws, and bits of silicified wood 

 were scattered in every direction along the whole face of the outcrop. 



XV. Eighteen feet of sandstone full of iron-stained concretions of peculiar 

 form. 



XVI. Twelve feet of gray sandstone. Over this was a bed of gravel and 

 sand, 7 feet in thickness, which sloped gently down to the base of Haystack 

 Mountain. 



XVII. Sixteen feet of argillaceous sandstone. 



XVIII. Sixteen feet of fine green sandstone. Two feet of very bright 

 green sandstone. 



XIX. Thirty-four feet of clayey sandstone, green within, but pink on the 

 surface. 



XX. Thirty-two feet of sandstone similar to XIX., but coarser. 



XXI. This was in three layers. First came 2 feet of green clayey sand- 

 stone; then 16 feet of a like material weathering pink; and finally 6 feet of 

 very coarse sandstone bright green in color. 



XXII. Similar to XIX. Eight feet thick. 



XXIII. Like the lowest layer of XXI. Forty-seven feet thick. 



XXIV. A bed of argillaceous sandstone thirty -five feet thick, and weather- 

 ing pink, purple, and brown. 



XXV. Six feet of coarse green sandstone like the top layer of XXI. On 

 this was a stratum 17 feet thick and similar to XIX. 



XXVI. Another bed, 6 feet thick, of coarse green sandstone like the lower 

 one of XXV. ; 4 feet of clayey sandstone like XIX. ; and 2 feet of fine sandstone, 

 white when dry, but green when wet. 



XXVII. Forty-one feet of clayey sandstone weathering to a rusty brown 

 color. 



XXVIII. Very coarse sandstone, green in color, but turning pink on 

 exposure,
