Mar., 1910.] Pennsylvanian Limestones. 107 



about 4 miles west of the exposure on the Ellet farm. This 

 stratum is quarried and bttrned on a small scale by the Clap- 

 saddle Brothers and is used by the Alliance City Disposal Plant 

 which uses about 200 bushels of lime per week. 



The quarry is opened beside a small run and nearly at run 

 level. This stratum is 5 feet thick and lies at 1117 above sea. 

 In places it is said to exceed this measurement and rests upon 

 coal 5 to 18 inches in thickness. It is composed of several layers, 

 is bluish gray in color and fairly fossiliferous. The upper third 

 is somewhat lighter in color than the lower part, and the quarry- 

 men state that this limestone produces a purer lime than the stone 

 at Middle Branch. 



No other limestone was found and the identity of this stratum 

 would be difficult, if not impossible, to determine from what can 

 be seen of it and the associated strata. In the absence of other 

 data its identity may possibly be established in another way. 

 Since the elevation of the Vanport at the Cement Plant is 1180, 

 and 1081 on the Ellett farm, the strata are seen to dip toward 

 Alliance 10 feet per mile. If this limestone in question be the 

 Vanport then at 4 miles to the west of the Ellett farm it should lie 

 at 1121 which is within 4 feet of the elevation actually found. 

 If it be the Putnam Hill limestone whose elevation at the Cement 

 Plant is 1143 and 1032 at Alliance having therefore, a dip of 11 

 feet per mile, at the Carr farm it should lie at 1076 which is 41 

 feet lower than the limestone is found to be. This would seem 

 to identify it as certainly the Vanport. But the presence of a 

 low fold between Alliance and Middle Branch would alter this 

 conclusion. No evidence, however, of such a condition is known 

 to the writer, hence he regards this as an outcrop of the Vanport. 



Another section in the northeastern corner of the county is 

 of interest in this connection. About 3 miles northeast of the 

 Carr farm and on the diagonal road leading from Limaville to 

 Marlboro at a point 2\ miles southwest of Limaville is the shaft 

 mine of Mr. Fred Lare. The elevation of the top of the shaft is 

 about 1155 feet above sea. 



Mr. Lare gives the following section: 



4. Drift 42 feet. 



3. White sandstone, hard and shaly 3 " 



2. Shale, dark 15 " 



1. Coal, bone parting near middle 4 " 



This 4 foot coal which is said to be a good steam and heating 

 coal lies at about 1095 above sea which is at once seen to be below 

 the Carr limestone and with no trace of limestone in the shaft. 

 The thickness and the parting in the middle strongly suggest the 

 coal beneath the Putnam Hill limestone. This shaft, the Carr 

 farm, and Howenstein are in line. The Vanport at Howenstein 

 lies at 1086, on the Carr farm at 1117 and the two points are 16
