   Near Death after Blast at Fremont
   
   Two men were injured, one perhaps fatally, in an explosion in the Bulton and Herrick blacksmith shop at Fremont about 10 o'clock Saturday morning.
   
   The injured:
   
   W. D. Hazen, 70, North Fond du Lac, skull fracture and severe bruises about right side of the face, caused by penetrating steel.
   
   William Herrick, 31, Fremont, owner of the blacksmith shop, lost his left arm at elbow.
   
   The accident occurred as Herrick was heating a large drill preparatory to sharpening it. The drill, used in quarry work, suddenly exploded, scattering pieces of steel throughout the building. Hazen was standing near Herrick watching the progress.
   
   The men were immediately taken to St. Elizabeth hospital.
   
   Two theories were advanced to explain the explosion. Some thought fragments of dynamite might have been on the drill, which was about five feet long. Others pointed out the drill was hollow, and that the heat might have caused gasses in the drill to expand.
   
   Herrick has a wife and six children. Hazen was visiting the Herrick family.

   Seek Cause of Fatal Blast in Fremont Shop
   
   Waupaca Co. authorities have started an investigation into the cause of the accident at Fremont Saturday morning when a quarry drill exploded killing W. D. Hazen, 70, formerly of North Fond du Lac and injuring William Herrick, 31, Fremont, owner of the blacksmith who now is in St. Elizabeth hospital suffering loss of an arm.
   
   Theories have been advanced that the drill which was to be used for work at Readfield, was hollow and might have been filled with nitro glycerine or that dynamite caps might have been placed in it for safe keeping. The investigation is being held to determine if and how the explosives were placed in the drill without the blacksmith being informed. District Attorney L. D. Smith, Waupaca, has secured bits of the drill found about the blacksmith shop and is taking them to Madison for examination to determine the cause of the explosion.
   
   Hazen was visiting relatives in Fremont and was in the habit of going down to the blacksmith shop mornings, to help. Pieces of steel from the exploding drill fracturing his skull and penetrated the right side of his face. The roof and walls of the blacksmith shop were peppered full of holes by the flying steel. Fire started after the explosion but was extinguished by townspeople who rushed to the building.
   
   Herrick's arm was amputated immediately after being brought to the hospital here and his condition was considered very satisfactory. He is married and has six children.
   
   Funeral services for Hazen will be held at 2 o'clock Wednesday afternoon from the Holly undertaking parlors, Waupaca, with burial in Lakeside cemetery.
   He is survived by the widow; two daughters, Mrs. E. M. Kopp, Highland Park, Ill., and Mrs. John Button, Fremont; two sisters, Mrs. John McCalla, Mount Vernon, O., and Mrs. John Beckholt, Hunt Station, O.; and seven grandchildren.

   Chemists Examine Pieces of Drill
   
   Investigation into the cause of explosion of a drill which killed one man and maimed another at Fremont, Saturday, rested Tuesday while chemists at Madison examined bits of the drill sent them by District Attorney L. D. Smith, Waupaca. A report from Madison is expected by Waupaca authorities Wednesday.
   
   The dead man is W. D. Hazen, formerly of North Fond du Lac who suffered a fractured skull that caused his death after entrance in a hospital here. William Herrick, the maimed man, is still in the hospital here but his condition is favorable.
   
   Admitting they have no clews which might indicate foul play in the explosion but desirious of setting at rest stories being circulated throughout the county and determine if possible what really caused the explosion, the Waupaca Co. authorities opened the investigation in the only possible channel. The accident was unusual, in opinion of the authorities, who discount the theory that explosives might accidentally have been left in the drill or that it exploded from expansion by the heat or gases which might have formed in the hollow part of the drill.
