infrequently found is the "domestic hand-ax,"* a pebble with one end 

 roughly chipped to an ax-like edge. These rude forms, together with 

 the chips and Hakes, make up for the most ])art the great mass of re- 

 mains, but here and there occur the butts and tips, and occasionally a 

 perfect specimen of the leaf-shaped knife. (See Figs. Plates ix-xiv.) 

 No pottery is found, and but three arrow-heads have thus far rewarded 

 the search of the writer. (Cat. No. 146571, U. S. Nat. Mus.) These 

 were found at the foot of the hill and are made of argillite, while the 

 other work is in quartzite, the pebbles of which in main constitute the 

 gravel beds of the hill. 



On the level at the top of the hill may be seen small patches of ground 

 littered with the smaller chips, among which have been found quite a 

 number of the tips and butts of knives. A deep ravine with a small 

 stream at the bottom cuts the hill about midway, and in the bed of this 

 stream, as well as that of the branch, the debris occurs in abundance. 

 The sides of the ravine furnish an exposure in places of several feet, 

 and from the face of this exposure the writer Las taken chipped stones 

 that were under four feet of soil and gravel. The same thing and under 

 like conditions may be observed along the bank of the branch where 

 it has been cut away by the action of the water. 



At the foot of many of the trees standing on the iiill-side are consid- 

 erable accumulations of chips, with worked and unworked stones, that 

 have drifted down the hill till intercepted by the base of the tree. 



These observations have been confined to the remains and the con- 

 ditions under which they are found on the north bank of Piuey Branch 

 and below the Fourteenth-street roadj but similar work, though in less 

 quantity, is found on that part of the hill above the road, as well as on 

 the south side of the branch and opposite Blagden's hill. Along the 

 banks of Eock Creek, below Piney Branch, other workshops have been 

 located, though not covering so large an area or showing an equal 

 amount of work in the same space. One of these, however, on the west 

 side of the creek and just above Oak Hill Cemetery, will doubtless make 

 as good returns under the same exploration as the larger shop on the 

 Piuey Branch. The grading on the east side of the creek during the 

 past year has so modified the original topography of that bank and the 

 adjacent hills that but little remains now to be seen of places that once 

 furnished considerable evidence of aboriginal work in stone. 



The collection from Piney Branch is made up of unfinished imple- 

 ments, forty pieces ; butts and tips of knives, thirty-one pieces ; rude 

 implements, cores, etc., twenty-seven pieces; and a box of flakes and 

 chips. (See catalogue.) The work from this place should be compared 

 with that from the village sites. The wonderful similarity of corre- 

 sponding series (a similarity which renders the substitution of one for 



"See Abbott's Stone Age iu New Jersey.
