men into a steel bucket which is swung by a boom derrick to the 

 canal boat and dumped. The gypsum is all shipped in crude state 

 to Mr Miller's plant in New York city where plasters of various 

 kinds are made. 



Quarry of the National Wall Plaster Co. This quarry is situ- 

 ated south and west of the Miller quarry on the same knoll. The 

 gypsum bed is continuous with that in the Miller quarry but is not 

 quite so thick. The property includes about 15 acres underlain 

 with gypsum. Quarrying is carried on intermittently and at present 

 no work is being done. The overburden is similar to that of the 

 other quarry but stripping is accomplished by excavating the gyp- 

 sum in such a way as to undercut the limestone beds and the latter 

 are then allowed to fall into the vacant space. The ro'ck was for- 

 merly hauled to the canal and to the mill but the latter now stands 

 idle. The equipment of the mill consists of a Sturtevant jaw crusher, 

 a set of Hoagland rolls, Cummer kiln and cooling bin, two lo-ton 

 kettles, and a buhrsto'ne mill. The rock was first crushed, then 

 passed through the Hoagland rolls which reduced it to the size of 

 corn. A large quantity of it was shipped in that state to cement 

 manufacturers. Some of this crushed rock was passed through the 

 Cummer kiln at a temperature of 340° and shipped without grind- 

 ing. Some was also ground in the buhrstone mill and calcined in 

 the kettles. The future of this company is still an unsettled 

 question. 



Quarries at Fayetteville. To the east of these quarries are 

 those of H. H. Lansing, now idle ; and also idle quarries formerly 

 owned by the Adamant Wall Plaster Co. and C- A. Snooks, but 

 now controlled by Clifford Miller. 



Large amounts of a similar grade of gypsum are found in all of 

 these quarries and extending into the several hills. What is most 

 needed at present is an outlet for shipping, such as would be fur- 

 nished by a railway switch now being contemplated, or by aerial 

 tramways or bucket carriers to the railroad or the canal. Another 

 improved method, not yet introduced in the region, is mining by 

 means of adit tunnels driven into the hillsides. This would obviate 

 the necessity of closing down in bad weather and would do away 

 with the expense now incurred in stripping. 



At Fayetteville there are mills owned by Bangs & Gaynor and 

 F. W. Sheedy. Each is equipped with jaw crusher, nipper and 

 buhrstone mills, and grind gypsum. Their mineral is purchased 

 from the neighboring quarries. The ground gypsum is sold as land 

 plaster or to fertilizer companies.
