BONE CAVE AT PORT KENNEDY. 275 



lugs, argillaceous or sandy, thickly peppered with angular stones, traversed the 

 exposure, with a central down-swing from wall to wall. They were divisible on a 

 large scale into four zones of stratification, counting from the top downward (see 

 fig. 5), namely : 



Fig. 5 (Scale 1 in. equals 4 feet).— THE POET KENNEDY BONE CAVE. 



Rough sketch showing the stratification by water. The black subdivisions 1 and 3 alone containing 

 vegetal remains appear identical. Subdivision 1 probably marks the lowest point reached by Wheatley in 

 1871. The remains of the smallest animals lie in subdivisions 3 or 1, otherwise there is no distinction in 

 fossil contents of the zones of deposition. 



Subdivision i. 



Two inches to one foot thick, faulting downward against the right cave wall. 



A black zone of fine sanely clay and loam, containing few stones, faintly visible 

 at the first inward digging, but becoming thicker and darker as we advanced 

 horizontally, until its seeming disappearance at the fifth foot inward. Its deep 

 black color and comparative freedom from stones clearly distinguished it from 

 the layer below it. In its dense mass of fine, blackened and decomposed sticks, 

 grasses and leaves, mixed sparingly with seeds, mosses, nuts and larger twigs, 

 after the manner of muck deposits in swamps, lay not a few bones and jaws of 

 small mammals, while the remains of larger species found in it crushed into 

 fine pieces seemed less numerous than in the zones below.
