 Can we venture to reach out from the particular

 area, I am happy to state that I believe my efforts 

 have been crowned with a full measure of suc- 

 cess. What held good in a particular field holds 

 good of a county, and what I now claim for the 

 tide-water portion of the valley of the Delaware

In no case have I been able to find stone im- 

 plements significantly distributed over a consid- 

 erable space i. e., tracts of five hundred to a 

 thousand acres except where there was, or very

 river and creek valleys the result was the same :
