Gypsum industry 



There are two plaster mines within the county, both located 

 in the southwest corner, in the town of Wheatland on Allen's 

 creek; one at Garbutt and the other 2% miles westward at 

 Wheatland Center. 



The one at Garbutt is that of the Lycoming Calcining Co., 

 superintended by Mr C. A. Sweet. It is located on the south 

 side of the creek opposite the mill and is reached by a trestle. 

 The entrance to this mine is by a tunnel into the side of the hill. 

 The pla'ster bed worked is what is known locally as the upper 

 bed, and here runs in lenses and ridges from 4 to 6 feet thick. It 

 is overlain by about 40 or 50 feet of waterlime and dirt. Con- 

 siderable " dirt " is found at points in the gypsum where the 

 calcium sulfate has been dissolved out, leaving a clayey, dirt- 

 colored residue. Owing to the unstable nature of the roof, 

 much timbering is necessary. The work is carried on in several 

 different headings, with two to six men at a heading. From 

 20 to 40 men are employed, and as high as 100 tons of gypsum 

 are removed in a day. Drilling is done with " New Auger " 

 coal drills, and the blasting with a low grade dynamite. The
