On the land of 0. J. Riggle in the northeastern part of Section 18, 

 Hopewell Township, the limestone is coarse and siliceous in character, 

 and exceedingly fossiliferous. Extensive collections were made in 

 the bed of the small stream just west of the road. Collecting is good 

 as the fossils are abundant, well preserved, and easily obtained.
