2. Bhekauli. 
Two pits were seen just west of the Satara-Mahabaleshwar road at 
about 29 J miles from Satara. As usual the manganese-ore nodules 
occurred in laterite soil resting on a crumbly decomposmg trap. A fairly 
large number of psilomelane concretions of curious botrj'-oidal shapes 
had been collected into small heaps ; a sample taken from these show-

3. Chikhli. 
About 4 miles S. by E. from Mahabaleshwar, and a little west of 
Chikhli village, is a fiat piece of ground at a level of about 4,100 feet, 
with small elevations or hills of laterite rising from it. A large number 
of small psilomelane concnjtions were found scattered on the surface, 
and a pit put down in one place showed 1 to 2 feet of brown clayey soil 
containing nodules of manganese-ore together with some laterite frag- 
ments. This rested on crumbly altered red trap containing (1) spots 
of a soft greenish-white stuff, corresponding, 210 doubt, to original amyg- 
dular infilUngs ; and (2) soft white phenocrysts that were probably 
once felspar. The manganese-ore when fractured shows, as already 
noticed on page 663, tiny specks of a substance very similar to the green- 
ish-white amygdular material. This is the locality at which I saw the
