2 feet yellowish gray limestone, white crys- 

 1339 tallines ; gypsum in small thin veins. 



4 feet pinkish gray limestone ; gypsum in 

 seams and veins. 

 1343 11 feet brownish-gray hard limestone. 



At 1348 feet the first salt found was observed in a few 

 thin veins, in some of which the vein matter was of salt, in 

 others the wall matter was crystalline gypsum with which a 

 thin layer of salt was intercalated. The salt was pinkish or 

 cream color ; the gypsum was white or pink. 



1354 1 foot 6 inches marl bluish gray, salt and gyp- 



1 355' 6" sum in veins. 



6 inches nodular layer of gypsum. 

 "" 2 feet dark gray limestone containing a large 



1358 percentage of salt and crystals in nodules. 



2 feet bluish gray marl, with many seams and 

 1360 veins of salt. 



6 inches very thinly laminated limestone, with 

 1360' 6" salt in seams. 



8 feet 6 inches bluish gray marl, with many 

 cracks filled with white and pinkish crys- 

 talline salt ; considerable gypsum. 



At 1369 feet at the south end of the shaft a bed of nearly 

 pure coarsely crystalline salt was reached, which on the east 

 wall of each shaft showed a dip of 1 foot on the upper line 

 of contact, and 4 feet 8 inches on the lower toward the 

 north, the layer being 8 inches thick at the south end and 3 

 feet at the northeast corner. A small proportion of shale is 

 mixed with the salt. 



1369 4 feet marl with pink, milk colored salt in veins 



1375 and seams, gypsum present, not abundant. 



2 feet transparent salt in large fine crystals, 

 5377 mingled with marl.
