in fig. 60. The miues were siibsequeutly investigated more in detail 

 and by excavation and clearing out the now filled galleries. This was 

 done by Mr. J. Park Harrison.' Fig. 01 is a reproduction of the plan 

 of his excavations. It represents but an infinitesimal portion of the 

 mined area. It shows but six pits or shafts, while fig. (iO shows them to 

 have existed by the hundred. These pits present on the surface much 

 the same appearance as those at Flint Ridge. The excavations in fig. 61 

 show what has been suspected long before — that these pits are deep, 

 going down through the chalk to the bottom of the flint deposit, and were 

 thence carried in horizontal galleries as in all mining under similar

conditions, digging out the flint and bringing it to the surface for use. 

 Fig. 61 is introduced to demonstrate this fact, and also to show the 

 extent and magnitude of the work done and to suggest the social condi- 

 tion of a people capable thereof. The shaded lines show the walls of the 

 galleries left for support, while the white between shows the excavated 

 galleries, rooms, and halls. The reexcavation brought to light not only 

 the stratum of flint to be mined but showed that which had been mined, 

 also the mining tools, as deer-horn picks, stone hammers, and mauls. 



Only three or four out of the thousands of implements found at Oiss- 

 bury bear traces of polishing, and these were broken.
