Mansfield's, Volusia County. 



On the eastern shore of Lake Harney, near the palmetto cabin of Mr. Mans- 

 field, is an un stratified mound about 2 - 5 feet in height. Its circumference is 120 

 feet. It has been under cultivation. Excavation revealed nothing of importance. 



Raulerson's, Volusia County. 



At the southeastern end of Lake Harney, near where the river enters the 

 lake, surrounded by palmettoes are two cultivated shell fields belonging to a man 

 named Raulerson. One of these fields is in the form of a ridge, the southern ex-

 south, and 180 feet in circumference. Its height above the remainder of the shell 

 ridge is but 1 foot 3 inches. Its shape is regular, save to the south where it slopes 

 to the adjoining marsh not over a hundred yards from the shore of the lake. 



The mound has entirely escaped the notice of all previous investigators, and 

 in 1875 the writer killed a wild cat in its immediate neighborhood without becoming 

 aware of the existence of the mound. It was then thickly covered with palmettoes and 

 its presence, or at least its nature, was certainly unknown to a man named Tanner, 

 whose cabin formed the only residence on the borders of the lake. At Tanner's 

 death the house was occupied by a man named Mansfield, who also was unaware 

 of the presence of an artificial formation upon the place. In the summer of 1891 

 Mr. Singleton, the tenant, cut down the palmettoes with a view to the cultivation 

 of the spot, since shell hammock is highly prized in Florida; but neither plow r nor 

 grubbing hoe was used upon the surface of the ground, which was, previous to the
