implerwents, animal bones, and perhaps also human bones, which are 

 imbedded two or two and a half feet ])elow the surface, between the 

 black soil above and the sand below. These pieces of pottery, and 

 also those from the last described mounds, exhil)it a greater resem- 

 l)lance to that from the lower Mississippi valley, collected by Capt. 

 Hall, than to that which we usually find in the mounds here, and, on 

 the whole, I am inclined to the opinion that these mounds are less 

 ancient than the most of those in this section of country. A closer 

 investigation in the future, may, perhaps, furnish more satisfactory 

 evidence in respect to this supposition. 



In comparison with the results of last year's exploiations, we have 

 been this season much less successful in the collection of relics, part- 

 ly on account of ovn- diminished financial resources, and partly and 

 chiefly because we had less opportunity for working- in the more im- 

 portant mounds; perhaps, also, we were less fortunate in our selec- 

 tions in the several groups. We hopij. however, to continue these 

 researches, and, next year, with increased success.
