Miscellaneous and Scattered Borings 
The borings tabulated below represent data gathered from examinations 
of the records and materials of deep wells, plunger elevator holes, tests for 
foundations and other similar sources. Only those whose materials were 
personally examined are given a definite formational name. In a few 
others, such as those at the Navy Yard, in Brooklyn, the published descrip¬ 
tions are so carefully worded that there is little doubt of their meaning. 
These are all plotted on the accompanying maps. 
Astoria Light and Power Co. 
Several deep wells at Lawrence Point, on the Long Island side of East 
River. Manhattan Drilling Co., contractors.
