CERTAIN ABORIGINAL MOUNDS, CENTRAL FLORIDA W.-COAST. 379 



Mound near Rock Landing, Citrus County. 



Crystal river is the output of a great spring about seven miles, by water, from 

 the Gulf. 



Rock Landing is about 3.5 miles from the mouth of the river. 



In scrub, about 1.5 miles in a NE. direction from the landing, on property 

 under control of Mr. R. J. Knight, of Crystal River, was a mound 3 feet 3 inches 

 in height, with basal diameters ef 40 and 50 feet. 



Thorough investigation showed this to have been a domiciliary mound. 



Mound near the Shell-heap, Crystal River, Citrus County. 



In full view from the river, about 4.5 miles from the mouth, on the left-hand 

 side going up, is a great, symmetrical shell-heap, on property under control of Mr. 

 R. J. Knight, of Crystal River. 



This'shell-heap, marked A on the plan (Fig. 16) is 28 feet 8 inches in height, 

 is oblong in horizontal section and has basal diameters of 182 feet NW. and SE. 

 and 100 feet NE. and SW. The summit plateau is 107 feet and 50 feet in the 

 same directions, respectively. A graded way 80 feet long and from 14 feet to 21 

 feet across, ascends from the level ground to the summit plateau on the NE. side of 

 the mound. 



Beginning at the NW. corner of this mound is a low, irregular shell deposit, 

 marked B on the plan, extending to the northward then curving to the eastward 

 and extending for a distance along the river bank. 



About 115 yards in a northerly direction from the great shell-heap is a circular 

 embankment of sand, marked C on the plan, of irregular height and width, the 

 maximum, respectively, being 6 feet and 75 feet. Within this circle is certain ter- 

 ritory on the general level, marked D on the plan, and an artificial elevation of 

 sand, irregularly sloping (E). This elevation culminates in a mound of sand, 

 marked F on the plan. While difficult to determine where the artificial elevation 

 ended and the mound proper began, to call the diameter of the base of the mound 

 70 feet, would be a fairly correct estimate. The height of the mound proper from 

 the east, where it bordered the level ground, was 10 feet 8 inches. Cross sections 

 of the elevated ground and the mound proper are shown in Fig. 17. 



In a northerly direction from the circular embankment are two ridges of shell, 

 one (G) low and irregular, the other (H), 12 feet in maximum height, with a 

 graded way. 



Certain excavations made in the level ground outside and inside the circular 

 embankment, yielded negative results. 



Excavations in the embankment showed burials in the southerly portioa where 

 the embankment was highest and one burial in the western part. Our work, how- 

 ever, on the level ground and in the embankment was not exhaustive. 



Eighteen men, with four men to supervise, dug seven days, demolishing the 

 entire mound and going through much of the elevated ground surrounding it. The
