trated in digging for water, nothing therefore is known with 

 respect to them, but that they exist there. 



In the first stratum, as in the other field, no organic remains 

 have been observed. In the second, but always within two 

 feet of the third stratum, have been found the teeth and bones 

 of the hippopotamus, the teeth and bon«s of the elephant, the 

 hornSj bones, and teeth of several species of deer, the horns, 

 bones, and teeth of the ox, and the shells of river fish. 



The remains of hippopotami are so extremely abundant, 

 that in turning over an ar^-a of one hundred and twenty yards 

 in the present season, parts of six tusks have been found of 

 this animal, besides a tooth and part of the horn of a deer, 

 part of a tusk, and part of a grinder of an elephant, and the 

 horns with a small part of the skull of an ox. One of these 

 horns I had an opportunity of measuring, as it lay on the 

 ground, and found it to be four feet and a half in length, fol- 

 lowing the curve, and five inches in diameter at the large end; 

 it was found impracticable to remove it, otherwise than in 

 fragments, which I have preserved, and have hopes of being 

 able to put a considerable part of it together. The immense 

 size of this horn is rendered more remarkable, by another 

 horn from the same spot, which measures but six inches in 

 length. Though this stratum is so extremely productive of 

 the remains of animals, yet there are but few good cabinet 

 specimens from it, owing, it is presumed, to their having been 

 crushed at the time they were burijd, and to the injury they 

 have since received from moisture. It is necessary to re- 

 mark, that the gravel stones in this stratum do not appear to 

 have been rounded in the usual way by attrition, and that the 

 bones must have been deposited alttr the fle^h was off.
