The Cemetery Shell-heap. 



About an eighth of a mile south of the Great Salt Pond, and 

 a few rods northeast of the cemetery, shells, bones, implements, 

 and pottery were found together in a layer, which nowhere 

 exceeded ten inches in depth, but was spread irregularly over 

 an area of about seven hundred square feet. Because of its 

 situation, it will be referred to as the Cemetery Shell-heap. 

 The border of the deposit at the roadside had been broken up 

 by ploughing, and at the time of exploration lay bare, while 

 the rest was hidden by a few inches of soil which bore a strong 

 turf. The list of the animal remains and implements obtained 

 from this deposit is given below, and will be found to contain 

 two vertebrate species not in the preceding lists.
