of 700 feet), and 30 to 35 feet high; the sides have a very steep 

 slope, 70"; the top is flat, oval, measuring about 30x50 feet. 

 The mound is situated on a bottom, near the bank of a creek, in 

 a deep ravine. Excavation to a depth of 12 to 14 feet yielded 

 pieces of hematite, some of which were burned, and two arrow- 

 heads. In another paper ^9 the same author describes a 



mound of simple construction, with a diameter of 30 feet and a 

 height of 4 feet. A {&\n feet from the surface were found a num- 

 ber of irregularly-scattered stones and pieces of wood ; at 5 feet 

 a quantity of ashes, with burned bones, fragments of dark-colored 



pottery, two knives of copper, and a copper spear-head. A 



human skeleton was found in a ditch excavation ; near it were 

 three ornaments of rolled copper, an arrow-head, and a bit of 

 blanket. 



With no other location than "Mr. Heisig's farm," the same 

 author ^9 describes a group of three mounds, arranged in an equi- 

 lateral triangle, in an open, level field; they are about 15 feet in 

 diameter and 3 feet high. Structure : {a) consists of hard mixed 

 soil to a depth of 2 feet below the original surface ; {b) consists 

 of 3 feet of light earth, then 2 feet of mixed earth; {c) is like 

 {a) in all respects. A similar group in number, size, ar- 

 rangement and construction is mentioned as near Fairfield. 



One mile from Spragucville, on a hill near a creek is a mound 

 composed of light earth, 15 to 20 feet in diameter and a few feet 

 high ; at 4 feet depth a human jaw-bone was found. ^9 This 

 mound is also mentioned in ^74. 



In lozva Township, four miles below the mouth of the Maquo- 

 keta and one-half mile from the Mississippi, on the Thomas 

 Boothby farm, near "The Point," is a group of nine mounds; 

 the land rises abruptly from the river; the mounds are in a single 

 row ; four of them have been examined by Mr. J. W. Boothby 

 with the following result : ^9 



{a) The furthest up the river ; an elongated pyramid 5 feet 

 high ; the remains of seven skeletons were found ; all were lying 

 on their backs, three with heads east, four v/ith heads west; un- 

 under the skull of one of the latter was a thin copper crescent; 

 above the skeletons were three or four large stones ; on the floor 

 of the mound, 4 feet north of the centre, was an earthen vessel
