south from Champaueer, at the north-east base 

 of the hill. To the north they stretch for a considerablie distance^ but 

 have not been examined. There is also a small tract of hilly country 

 a few miles further south, which appears to consist of them. As it does 

 not appear at all certain whether they can be referred to any one of the 

 systems of rocks hitherto described as intervening between the metamor- 

 phies and the Vindhyans in Central India, it appears best to give them a 

 temporary and local name, and that of the old town 

 of Champaneer, the former capital of the Mahom- 

 medan Kingdom of Guzerat, appears best suited for the purpose. 



The principal constituent rock of the Champaneer beds is quartzite or

metamorphics. The other beds are mostly slates, conglomerates, and 

 limestones, ferruginous bands occasionally occurring. Some of the lime- 

 stones are highly crystalline ; in one place near Kudwal they were found to 

 contain actinolite ; in other places, as near Soorajpoor, they were quite 

 unaltered. All the rocks susceptible of cleavage are highly cleaved, the 

 planes striking about west 10°-20° north in general. Some of the slate ap- 

 pears to be so fissile that it might probably be made available for roofing. 



The conglomerates are perhaps the most distinctive beds in the 



group. They are well seen about Jhubban on the

 matrix is in general a coarse gritty sandstone, containing pebbles and 

 boulders often a 'foot in diameter, and occasionally more (one was mea- 

 sured which amounted to 3 feet), and consisting of granite, quartzite, talcose 

 slate, and crystalline limestone. The talcose slate of which some of the 

 pebbles are composed is scarcely more metamorphosed than the Champaneer 

 beds themselves. The quartzite boulders are the largest. The limestone
