The first exposition of conservation and its builders; an official history of the National conservation exposition, held at Knoxville, Tenn., in 1913 and of its forerunners, the Appalachian expositions of 1910-11, embracing a review of the conservation movement in the United States from its inception to the present time . seem probable all such acci-dents were reported. The greatest reported loss of life due to a well was 29. Itseems evident that the danger to operating mines must increase under existingconditions attending well operations. A few figures will make the situation clearer, but I must take these figuresmainly from Pennsylvania, for others are not available. On December 31, 1911, we had in Pennsylvania a total of reported wells to thenumber of 63,352. Knowing the conditions attending the oil industry it is certainmany wells are not included in the reports as received. We have no record of thenumber of abandoned wells, except for a few of the later years. Of this total of63,352 wells, over one-half are located in bituminous coal producing counties, andof the 10,807 gas wells included in the list, almost two-thirds are in the bituminouscoal region. In IHl there were 3,672 new wells reported, of which 426 were dryholes. Of old wells 1,647 were reported abandoned, or a total of 2,073 holes zo o uJ z OHa:ui(/Izou_i <z o H< z dz 5 Dm t/i t-< Z o:u I H DO z z < Q oo THE FIRST EXPOSITION OF CONSERVATION 197 abandoned during the year. How many of these were properly plugged, in thetotal absence of any inspection, one can only imagine. With the increased demand for oil the drilling of wells continues. In Juneof this year, according to the Oil City Derrick, East of the Mississippi, in the MidContinent and Texas and Louisiana fields 2,327 wells, in July wells and inAugust 2,381 wells were completed. East of the Mississippi in July 1,067 and inAugust 1,109 wells were finished and at the end of August wells were inprocess of drilling.
