GEOLOGICAL NOTES IN THE GIIEAT EXHIBITION. 
395 
has been worked since 1704. There is a second seam beneath it of 7 
fathoms. Brown coal is worked on the rivers Pleisse and Elster, upward 
from Leipsic, near Cannewitz, DehUtz, and Zobi^ker ; the deposit then 
continues as far as Groitzsch, where three seams are known, and from 
Pe({au up to Oderwitz, close to the Prussian frontier, where two seams are 
won of 57^ and 39 feet. This deposit becomes still more extensive, where 
the Wyhra joins the Pleisse, 7 fathoms having been bored without reaching 
the bottom. More to the south, scattered deposits are found on the right 
bank of the Pleisse ; also on the left bank of the Mulde, near Wurzeu, 
and on the right bank at Grehritz, Skorditz, Leipnitz (3 to 4 fathoms), 
Skoplau, and Zschadras (7 fathoms), Lausigk up to Eochlitz. Dispersed 
basins are found between the Mulde and the Elbe. 
There is also brown coal between the Elbe and the Oder. The latter 
measures appear in distinct veins at the edge of the so-called Lausitz hiUs, 
penetrating under the basin of Zittau, whence a connection with the im- 
portant basin of Bohemia takes place across the boundary of the Zollver- 
ein. These spread out also into the low country at the foot of the Silesian 
mountains as far as Neisse, and again appear in the plain between Witten- 
berg and Domitz, and even up to the vicinity of Stettin on the Baltic. In 
Saxony small measures are found nearOrtrand, Camentz, and Bautzen : in 
Prussia near Jauer, Eatibor (2 to 3 fathoms), Buschwitz (2j to 3^), and 
Doberschiitz (1^ fathoms). A very important basin is met \a ith in the dis- 
trict of Zittau; and an earthy kind of brown coal, called " sulphur-coal," 
is exported as a good manure to Bohemia and Silesia. From Zittau the 
brown-coal measures extend across the Prussian frontier, and follow the 
course of the Neisse in the department of Liegnitz. Ver}^ extensive seams 
are found at Schouberg (Lauban). One seam near Gorlitz is 50 feet. De- 
tached basins are known near Langenols and near Hennersdorf, in the dis- 
trict of Jauer, containing 13 to 27 feet of coal, and to the east of Striegau 
showing 56 feet. These brown-coal measures can be followed from Eoth- 
enburg to the limits of Liegnitz and Frankfurt on the Oder. To the 
north the brown coal is again found near Sorau and at Lodenau, covering 
a wide expanse. There are two seams, the upper one of 80 to 85 feet. It 
is also met with to the west at Spremberg, and in the district of the 
Hoyerswerda, on the left bank of the Spree. These measures terminate 
in the Duchy of Anhalt-Dessau. 
After a long break, brown coal is again found down the Elbe in the dis- 
trict of PerlelDcrg ; and seams are known in Mecklenburg, near the Prus- 
sian frontier. 
The large basin of Freienwalde, on the Oder, is divided into several 
parts; the first extending over 22 square miles, from Freienwalde to 
Frankfurt ; and others lower down in the neighbourhood of Schwedt, near 
Hohen-Zahden (south of Stettin), near Herzberg, and at Bucknow. More 
southern measures a]ipear at Eauen and Petersdorf, and then near Stre- 
ganz, the ancient monastery of Neuzelle, Einbeck, Gaemersdorf, and occu- 
pying a large tract of countr}' in the Griineberg district, where there is 15 
feet of very excellent coal. 
There are brown- coal measures also between the Oder and "Vistula. 
Single basins far apart occur at JS^ieder-Kranig, near Fiuhenwalde, where 
the seams reach 27 feet ; in Pomerania near Brietzig, Trampke, and at other 
places on the Baltic coast. There are measures near Landsberg, on the 
Warthe (Frankfurt) ; and l)rown coal is known near Landsberg and Kla- 
dow (7 to 20 feet), near Birnbaum, Zirke, Wronke, and Obornik (53 feet) ; 
near Trattin and Lassig, Grunow, Trebovv (25 feet), and Zielenzig. At 
the latter place two seams occur together, 32 feet, partly brittle and solid
