ADMINISTRATIVE REPORT 69 
Other groups of rocks between this island and Conowingo 
showed equally interesting carvings, but not so profusely. 
A pyramid-shaped rock standing well out in the rough and 
dangerous rapids had several fish outlines near its apex. A 
slab which had been broken from its original position and 
which might have been used for a shad-dipping stand, was 
marked with outlines of two slender fish and two tally marks. 
A number of interesting photographs and drawings of these 
pictographs were secured. 
In connection with a reconnoitering trip among the pre- 
historic quarries and workshops along the Susquehanna in 
the spring of 1922, Mr. Baer again visited these pictographic 
rocks and secured additional drawings and a number of 
plaster casts of the more important figures. Prehistoric 
steatite quarries were traced from the west side of the river 
at this point to Deer Creek in Harford County, Md. Those 
showing most work and offering best opportunities for 
investigation are near Broad Creek in woodland owned by 
James McLaughlin, near Robinson’s mill, and by W. C. 
Heaps, Mill Green, Harford County, Md. 
At a workshop below Peach Bottom, Lancaster, Pa., a 
number of unfinished and broken banner stones of pro- 
chlorite were found. The source of the material was located 
a short distance east of Bald Friar, Md. A large number of 
unfinished banner stones of slate were found at the work- 
shop on Mount Johnson Island above Peach Bottom where 
sO many specimens had already been found. At Fishing 
Creek, Bare Island and Henry Island evidences were found 
of considerable camp sites. At New Park and Fawn Grove 
in York County, Pa., have been found large caches of rhyolite 
blades. At both of these places and also at Peach Bottom 
in the same county were many artifacts and indications of 
burial grounds. Interesting specimens were secured from 
most of these localities.
