226 THE MINERAL RESOURCES OF CECIL COUNTY 



small indications of oil may be encountered at the surface or in wells. 

 The conditions necessary to the formation and preservation of work- 

 able deposits of oil are well understood and these conditions are 

 known to be lacking in Cecil county. Small films of oil may be 

 formed now and then from the decaying fossil remains but the 

 amount so formed will be small while the broken and permeable char- 

 acter of the deposits in which these fossils are found offers no oppor- 

 tunity for the concentration or retention of the small amounts of oil 

 so formed. These facts clearly show that the hope of making legit- 

 imate profits from oil investments in Cecil county is without any 

 reasonable foundation.
