104 STONE IMPLEMENTS [eth.ann.IS 



Of tbe peculiar stoues illustrated in the upper figures of i)late Lxxiv 

 I will uot venture to say more tbau that they are <ij)parei)t]y abradiug 

 iini)leiiients. but whether they were for the sluipinfj of stone tools or the 

 drt'ssiufi' ol' wood, boiii', or thongs can not be dcterniiiicd. The mate- 

 rial appears to be a dark-gray eruptive rock. The lower si)ccimen is of 

 a somewhat gritty stone and was probably a simple grindstone. All 

 are IVom sites about the head of tidewater on the Potomac. 



The hammerstones brought together in ]j4ate Lxxv represent the 

 varieties most common on the village-sites of the province. All are 

 from the tidewater Potomac. The smaller specimens in the upper line 

 are of qnartz and the others are of (juartzite.
