of bones, tusks and teeth. These latter pits have been constantly 
"watched by me ; and on the eighth of April last on visiting that at 
Biddenham, I found the men working in the direction where many 
bones had previously been found, and where a large portion of a 
tusk of Elephas primigenius had been taken out. I went into the pit

out of this part, and told the men to look closely at that which they
