west again as a parallel ba/ul situated about a furlong to the south of 
the main portion of the band. This southern band has been traced v\cst 
as far as the Kund Nala, a distance of l^- miles ; it probably corre- 
sponds to the limestone band that farther west lies about J mile to the 
south of the Mandvi Bir and Jutiawani workings, but which was not 
noticed to be manganifcrous where I crossed it. At the eastern end, 
where the band is apparently doubled at the surface, separate names have 
been given to the two portions. The northern is known as the Kaskuri 
band and the southern as the Bhdnddeo band, the portions to which 
these names are given being both within Junapani limits. Mr. Vreden- 
burg's opinion with regard to this duplication of the bands at the sur- 
face is that the limestone is in the form of a definite bed, which has been 
folded into a syncline, so that the two bands are two outcrops of the 
same bed of rock. The termination of the manganiferous limestone at 
Junapani is then explained on the h3'pothesis that the base of the 
syncline here comes to the surface. Everywhere the manganiferous 
portion of the limestone seems to be at or close to its base. 
The limestone band is very easy to trace, because its position can be 
found from that of the underlying rock, which often gives rise to small 
ridges and hills. This underlying rock varies in composition from a 
rock composed almost entirely of epidote and quartz, when it can be 
called epidosite, to one in which there is a large amount of felspar present, 
usually u'licrocline, when the rock can be called efidote-gneiss. Some- 
times quartz is very scarce or practically absent, the rock being then 
composed almost entirely of epidote and microcline. The name of 
this rock would also be epidote-gneiss. The rock underlpng the epido- 
sites is probably quartz-pyroxene-gneiss. l The rock overlying the 
limestone band is also probably the 'juartz-pyroxene-gneiss. Other 
rocks occurring in this area, though less closely connected with the lime- 
stones, are fine-grained schistose biotite-gneisses, and mica-schists,, There 
are also numerous intrusions of pegmatite and granite, often carrying 
tourmaline, in the limestones. 
It will be seen from the descriptions given below that there exist 
at several places, especially in the Junapani portion, considerable masses

count of the Junapani deposit there must be at this place a lenticular band 
or bed at least 40 yards long and some 4 to G or more feet wide ; whilst 
I myself saw several ore-bodies of considerable width (up to 12 feet) 
in Mandvi Bir and Juna wani. In addition to these there are abundant 
small nodules in situ in the limestone that could not be profitably worked
