From Kychtym to Ekatherinebourg the road passes over bands of 

 gneiss cut several times by granite (traversed by veins of syenite). 

 There is a region of chloritic talcose, etc., schists among which is 

 found for instance at the 91stwerst uralitic porphyry transformed to 

 schist. At the 99th werst these schists change the west dip to south 

 for half a werst. Beyond the station Maouk, where the schists 

 have been studied by Morozewiez, serpentines occur and predominate 

 to the 115th werst. 



The chloritic schist contains large crystals of Magnetite, the 

 talcose schist nests of radiating Actinolite of emerald green, and the 

 serpentines a number of veins of Asbestus. The whole is covered 

 by a bed of turf three meters thick. The serpentine contains 

 marble at the 126th werst. Among numerous hills of serpentine one 

 may observe numerous nuclei of gabbro and gabbro-diorite, and other 

 rocks giving origin to serpentine. The summit of the divide between 

 the waters of the Tschoussowaia and those of the system of the river 

 Isset consists of chloritic schist. Marble accompanied sometimes 

 by listvenite has been exploited for years in the vicinity of the village 

 Mramorskoe. Succeeding this for six wersts or more come gneiss 

 and granite, followed by more chloritic and talcose schists, etc., 

 accompanied by serpentines, diallage, pyroxenite, uralitic por- 

 phyrite and occasionally by granite and porphyry. 



Ekatherinebourg. — Chloritic schists occur within the limits of the 

 city, as well as listvenite, serpentine, diorite or gabbro-diorite, ural- 

 itic porphyry, usually changed into green so-called uralitic schist. 

 Here and there these schists contain beds of gneiss. 



Besides these (See L. G., VII) in the neighborhood occur lime- 

 stones and granite. 7 



While a part of the excursionists were examining the so-called 

 stone tents and the archeological remains of Werkk-Issetsky, others 

 visited the mineral localities of Eugenie-Maximilianovna to the 



7 Ekatherinebourg is the seat of a very active and learned society of amateurs 

 of natural history, which has made valuable natural history and archeological 

 collections. A fire destroyed many of the most valuable objects of the former 

 collection, but this has not prevented the growth of the society. Valuable 

 remains of a former tribe have been found on the island in lake Werkh-Issetsk 

 and in the vicinity of the hamlet of Palkino. M. George-Onesime Clerc is 

 the very efficient secretary of this society, a savant amateur, who has for 

 twenty-five years been the chief active spirit within it. He has recently 

 made the discoveries of human relics previously referred to, and desires to 

 be able to compare some of the objects with those of the North American 

 Indian.
