dipping east 75°, bring us to the 242d werst, where black dolomites 

 of fine grain intercalated with thin veins of calcite dip along with 

 the quartzites. Further on black argillaceous schists and chlorite and 

 argilo-chloritic schists appear. At the 230th werst the gabbros of 

 Douplianoi-kamen, a southern continuation of Teplogorskaja-sopka, 

 are met. From the 215th werst, at the maximum elevation of 

 469.7 m., the road pursues the crest of the water divide between the 

 affluents of the Wejai and the affluents of the Koiwa, and descends 

 rapidly for 43 wersts to the station Pachya. In the cuts between 

 the 189th and 185th wersts black argillaceous schists occur. Beyond 

 the station Bielaia, in a cut on the 184th werst, a light gray arkose 

 coarse-grained sandstone appears, and further on argillaceous schists 

 alternating with finely stratified sandstone. At the 177th werst 

 light gray, compact and dark gray crystalline limestones of middle 

 Devonic appear with Oyathophyllum. From this point to the station 

 Pachya the upper Devonic limestones appear with Cyrthia murchi- 

 sonia, Atrypa reticularis, Orthis striatula, etc. Beyond Pachya the 

 road enters the Carbonic deposits, which it follows to Vsieswiatskaia. 

 A cut at the 166th werst shows compact gray finegrained limestones 

 C I b with Spirifer mosquensis, Productus cora, Pr. semireticulatus, 

 Pr. Humboldtii, Chonetes variolaris, Fusulinella sphceroidea, etc. 

 From here to Vsieswiatskaia only a few outcrops are seen of white 

 quartzose, fine grained sandstone and clays. The occurrence of 

 Carbonic measures continues. At the 122d werst C f b again is seen 

 with Spirifer mosquensis, Pr. cora, Pr. semiret. Near to the junction 

 of the Arkhipovka and the Tschoussowaia C 2 crops out with Fusulina 

 vemeuili, Pr. cora, Spirifer stri., Streptorhynchus eximiceformis, etc. 



The limestones of the upper Carbonic dipping northeast in the 

 cut of the 121st werst hold a thin bed of calcareous sandstones of 

 greenish gray, with remains of calamites, species of Productus, etc., 

 interstratified with a gray conglomerate and an arenaceous schistose 

 clay. The presence of this permo-carbonic sandstone between the 

 upper carbonic limestones dipping to the northeast is explained by 

 a reversed fold to the southwest. 



To the north of the station Tchoussowaia the outcrops of the 

 white Gypsum of the permo-carbonic series are seen on a little hill. 

 From the station Tchoussowaia to Perm, a distance of 119 wersts, 

 only Permo-Carbonic, Permian and post-pliocene exposures are 

 found in the infrequent and shallow cuts. Between the stations 

 Lievchino and Motowilikha the road follows the right bank of
