The rest is gray plaster to the roof, sometimes solid and 

 sometimes interrupted by much loose dirt and by hollows. 

 The mill is run by steam power. 



Mr John W. Garbutt operates 3 pits and works 20 men 

 in the season. His capacity is about 4000 tons per year 

 his pits being operated similar to Mr Weeks'. His shafts 

 however are only from 25 to 30 ft. deep and he operates 

 the second bed only, his bed running about 6 ft. thick. 

 According to Mr Garbutt gypsum has been worked in this 

 locality for 80 years. He states that the presence of three 

 plaster beds here is well known their respective thicknesses 

 being about 6 ft. 



Mumford, the next gypsum locality to the west, is only a 

 few miles from Garbuttsville. The rock quarried is whiter 

 than at Garbuttsville. The Wheatland Land Plaster Co. 

 owns three pits here, of which two are now working. The 

 officers of the company are Sylvester Brownell, President; 

 W. D. Strobell, Treasurer; Warren H. Pease, Secretary. 

 The other members of the company are D. P. Campbell 

 and George C. Haaly, all residents of Mumford. The pro- 

 duct for October and November, 1892, each, was 380 tons. 

 Four men are employed at each pit and 3 men in the mill. 

 This company has just begun to operate this year, although 

 these quarries have been worked before some years. It 

 expects to do a business of some 10,000 tons per year when 

 well started, the present capacity being about 5,000 tons per 

 year. The plaster rock will average 6 ft. in thickness, the 

 roof being of water lime which is solid. The existence of 

 three plaster beds here is confidently believed. The plaster 

 is very flat here; wheelbarrows are used to handle the ma- 

 terial. Four men are the regular force in each pit. In a 

 new pit dug recently, considerable difficulty was met with in 

 the quantity of water, so it was closed up until dry weather, 

 when it is proposed to operate it. The beds run as follows : 

 18 ft. of hard bottom, 18 ft. of white gypsum, and the rest up 

 to about 6 or 7 ft. is mostly gray. Sometimes the stone
