436 CERTAIN ABORIGINAL REMAINS OF THE N. W. FLORIDA COAST. 



A graded way, 78 feet from its beginning to the edge of the summit plateau, 

 joins the mound on the southern side, somewhat east of the center. 



The mound is so surrounded by depressions, whence material for its construc- 

 tion was taken, that its exact height above the general level is difficult to get from 

 the exterior. From a point on the southern side the altitude is 10 feet, 7 inches; 

 from the northern side, 12 feet. In the digging it was found that the depth of the 

 mound from the surface of the summit plateau to the base was probably about 12 

 feet on an average. 



There had been much previous digging, the entire central portion of the mound 

 being fairly riddled with excavations. 



During our investigation eleven men on an average dug for seven days. This 

 digging consisted of trenching at various points to determine the construction of the

mound ; the removal of a large part of the summit plateau to a depth of from 3 to 

 5 feet; the investigation of much of the marginal portion on the northern side of 

 the mound (see diagram, Fig. 13, on which our principal work is shown). 



Not far from the base, on the northern side, a trench 67 feet across at the start 

 was continued in about 75 feet, converging to 45 feet at the end. This trench did 

 not" follow the base after sufficient work had been done to show we were dealing 

 with a mound originally used for domiciliary purposes and later heightened and
