NATURAL GAS EXPLOSION NEAR WALDRON, IND. 8 I I 



Fig. 4 — One of the fissures evidently formed by the earth cracking apart, owing

 background of the picture correspond to x-x 1 of Fig. i and are at the south side of 

 the main fissure, I, 2 of Fig. 1. 



When visited by the writer, four days after the explosion 

 occurred, a little gas was escaping from many of the fissures,

It was reported by the citizens of the neighborhood that a 

 fire had been burning in brushwood on a small island in the river 

 about 1 50 yards above the main fissure previous to the explosion,
