3345. Muthung's Survey Map of the mountain district of 

 Upper Silesia, original drawing, scale ^oVo in nine special sections, 

 from a to i of the chief section, No. 6, together with two network 

 maps for the north-eastern and south-western part of the drawing 

 lithographed on scale of TooV^u- 



Royal Prussian Upper Mining Court for the Provinces of 



Silesia, Posen, and Prussia (Breslau). 



This map, executed to the scale of 1 : 8000, is based upon a special tri- 

 angulation by Prof. Sadebeck, and Messrs. Sartor and Horold, in which are 

 inserted reduced copies of the official survey maps and other special plans of 

 mines, railways, towns, &c. The rectangular network of the map is deter- 

 mined by parallels to the meridian of the chief trigonometrical point of the 

 Trockenberg near Tarnowitz. 



334:6. Photographic reduction of the nine sections on 

 a scale of .^ 00 , not retouched ; carried out by Ed. v. Delden, 

 Breslau, viz., 



a. Nine unmounted small sheets bound in card. 



b. Nine small sheets mounted, like chief section No. 6 (3347) of 



the map drawing.

. . shows the photographic reduction of the nine original sections above 

 mentioned, as prepared by Ed. v. Delden of Breslau. On plate b. these 

 nine small sheets appear mounted and united to a chief section of the network 

 of the survey map. The maps 4-6 show the use of the photographic map 

 on the scale of 1:25,000 as a topographical basis for various mining and 

 other industrial purposes. The map shows the important mining districts of 

 the towns Beuthen, Konigshiitte, and Kattowitz, being the first sheet of a new 

 map of Upper Silesia, which was not only destined to exhibit the coal beds, 

 but also the important deposits of zinc and lead ores of the Muschelkalk basin. 



A special wall map is exhibited in which the mineral boundaries are shown 

 in different colours, but, as in those before mentioned, faint black lines are used 

 to show positions of places and boundaries of districts and mining rights. The 

 map illustrating the projected water-supply represents a larger district on the 

 same topographical basis, and shows the relation intended to be observed 

 between the supply and the consumption. 



3347. Principal Section, No. 6, of a map of a coal deposit and 

 ore deposit in Upper Silesia, scale TSOOO' To complete and 

 elucidate this, Horold's map of the ore deposits of the Polish 

 Upper Silesian Muschelkalk is added, scale -5^00? together with a 

 number of mountain profiles from Dr. Ferd. Homer's Geology of 

 Upper Silesia.
