Avhite marble, limestone with tremolite and augite, a hornblende 

 j'ock with some pyrites, galena, and green copper-ore, compact 

 and crystallized garnet, and lastly, gneiss with very small 

 veins of crystallized garnet. In a second quarry we find, reck- 

 oning in the same manner, gneiss, a hornblende or actinolitic 

 radiated fibrous rock, a mixture of this rock with garnets, 10 

 feet of granular limestone, limestone with tremolite, a bed 1 

 foot thick of crystallized garnets, 1| feet of greenish horn- 

 blende rock, felspathic gneiss with small stripes of hornblende 

 and garnet ; lastly, common gneiss. 



In the Perindagh the granite seems to occur oftener in the 

 shape of small dome-shaped hills, as in the undulating plateau 

 of the Kreshna hill ; when this happens, the gneiss contains 

 fewer veins of pegmatite. The northern and western sides of 

 the Perindagh are quite covered with these small granitic 

 domes. On the northern declivity of the Kreshna hill, white 

 granular limestone is also seen associated with quartziferous 

 gneiss containing veins of coarse pegmatite, and hornblende 

 rocks. There are two beds of this limestone, and the part in 

 contact with the gneiss contains augite. 



Between Seres and Salonichi, particularly between Gu- 

 mentsche and Schafsha, the decomposed granitic domes are sur- 

 rounded by gneiss with felspathic or pegmatite veins. The same 

 arrangement is also beautifully seen 1^ leagues W. of Kostendil 

 on the road to Egri-Palanka, and in this case the granite is por- 

 phyritic. Many of these veins are nearly parallel to the direc- 

 tion of the slaty structure of the gneiss. I found a most singu- 

 lar intermixture of granite and gneiss with granitic veins in the 

 hills W. and N. of Perlepe, on one of which are situated the 

 ruins of the castle of the famous Servian hero Marco Kralo- 

 witsh, the terror of the Turks. 



Sienite occurs in Servia in the N. E., central, and S. W. 

 parts ; and in Turkey on the Pepentz at two leagues N. of Us- 

 kub ; on the Strymon near Kosnitza (E. of Kostendil) ; at 

 Dubnicza; and "n the Neretska and Florina-Planina. In cen- 

 tral Servia the sienite forms a chain of hills, running W. and 

 S.W. of Kragojevacz, between granular limestone and primary 

 (transition) slates. Similar rocks also occur in the Rudnik 

 hills, near Karanovatz, and in the Kopaunik hills. In this last
