Annual Report for 1873 . 
or a metaphysician performing the Caesarean operation because a number of surgeons 
standing by chose to excuse themselves on the plea that they had never seen the thing done. 
No doubt a man of intelligence and education can always make some useful attempt at 
the supervision of mere skilled labour; and I have no doubt that Mr. Stewart would ac¬ 
knowledge his obligations in this way to Mr. Medlicott; but it is a fact that this geologist, 
when he was ordered to take charge of the borings he had recommended at Gadarwara, 
had only once before seen a boring in a casual way, and did not know the difference between a 
crab-winch and a jack-role, between a wrench and a spanner. I cannot but think that such 
important operations, depending entirely upon mechanical ingenuity and resources, should 
be under proper professional control and responsibility, and also that this should be forth¬ 
coming in some branch or other of the Department of Public Works. 
In the Damuda basin Mr. J. Willson spent the season in retracing the lines of the 
Ivaranpura coal-fields on the newly issued maps of the Hazaribagh district. 
Mr. Hacket was incidentally engaged upon these same formations, in adding to our 
collection of fossil plants from the Jabalpur group; but his chief occupation for the season 
was to trace the boundaries of the Vindhyan and older rocks on the now maps along the 
northern side of the Narbada valley in the Jabalpur, Narsingpur, and Ilosungabad districts, 
and at the same time to add to our collections from the ossiferous valley deposits. Mr. 
Hacket filled in a large area. 
In the same region, more to the north-east, Mr. W. L. Willson carried on the work 
of previous seasons, completing sheets 34, 35, 37, 47 and 48 of the new Topographical sur¬ 
vey of Riwah and Bandelkand, including rocks of the Vindhyan, the Bijawar, and the 
gneissic series. 
Mr. Mallet, having had much experience of the crystalline and metamorphie rocks in 
Bandelkand and the Son valley, took up an important section of the same rocks in South 
Bcliar, with the advantage of the new large-scale maps of Hazaribagh. So far as the 
comparatively small aroa of one season’s detail-work can be trusted, lb ore seems to be no 
marked stratigraphical break between the quartzite and slate series of Bekar and the gneiss 
of Bengal. In the middle of the season Mr. Mallet was recalled for some weeks to Cal¬ 
cutta to prepare our mineralogical collections for the Vienna Exhibition. 
Ear to the south-west of the operations already noticed, Mr. Foote was at work in the 
South Mabratta country. A section was run across the gneissic area lying between Bella ry and 
the Malparba river, a little to the north of which the south boundary of the Kaladghi series 
was crossed, and the previous season’s work joined on. Various parts of the ground near 
Kaladghi were gone over again to clear up obscure points. The south-east part of the 
Kaladghi basin was then surveyed, including the lino of outliers extending to Gudjaudergarh. 
From this point the south boundary was carried west to Murgod in Belgaum district. So 
much of the gneiss area was gone over as was necessary to close in the north-east quarter 
of sheet 41, and to connect the several quartzite outliers with the general work. After 
completing the above boundaiy, work was carried on in the quartzite area around Toragal 
and Ramdurz, till it became necessary to move into Kaladghi to arrange and despatch the 
collection of geological specimens for the Vienna Exhibition. 
The work remaining to be noticed is external to the rock-area of the Peninsula. In the 
extreme nor{h-wcst, Mr. Wynne was engaged in working out the ground to the north of the 
Salt Range where the tertiary series occupies a large area and forms the outer ridges of the 
mountain region. The top and bottom horizons are identifiable with the Sivalik and Subathu 
groups of the sections far to the east, but the same marked divisions of the series are not 
expressed in the west as in the east. At the base here, although the purely structural features
