52 ANNUAL REPORT 
aged the producers to such an extent that they began leasing territory in 
the vicinity of North Baltimore with reference to the development of an 
oil field. Later in the year a number of fine wells were secured in the same 
township (Henry), and from that period rapid progress was made.t 
The year 1885 demonstrated the existence of oil in the Trenton, and 
in the ensuing year development began rapidly. From the established 
centers the drill moved out in all directions, and during the same time 
much testing of the “wild-cat” type was done. The result was that in a 
short period the important fields had been outlined, and by far the greater 
part of the work done since has been in developing that territory. 
The following statistics, compiled from the Mineral Resources of the 
United States, tell plainly the growth of the industry.
