Human agency suggested itself but was dismissed on account of the 
vast abundance of the flakes. That this might; have been a work¬ 
shop patronised for many generations did not occur to me. But I 
now think that is a satisfactory solution of it. I saw no wrought 
implements - nothing but sharp flakes spalled or chipped off ap¬ 
parently, though if I ad searched I might perhaps have found some 
partially shaped pieces spoilt when partly worked and then thrown 
away. IJ suspect that you would add this place to your list of 
workshops if you could see it. Keep the ball a-rolling my dear 
fellow; you have made a good strike here and I rejoice to see it.
