 Millstones. , . 



a very similar rock of nearly black colour lu the 



tertiary beds, at Karimori hill, furnish strong tough millstones. These 



are also obtained from the ferruginous quartzite-like grit of a long ramp 



near Chundeeya, west of Anjar. 



Building stones abound in Kutch, the traps only not being 



extensively used for this purpose. Some of the 

 Building stone, . , . . . 



best varieties are furnished by the lower Jurassic 



rocks J and others much used are got from the upper tertiary beds; but 



any of the sandstones of the country are employed, though many of 



them are so soft and saline that they rapidly decay. The sandstones 



being so plentiful and so easily worked they seem to have been often 



preferred to better stone which might have been found either among the 



traps or elsewhere. Stone but slightly if at all saline is called meeta 



and that impregnated by salts, kara. The latter is of course more 



perishable. 



The finer grained slightly calcareous yellow sandstones of the lower 



Jurassic group form tolerable building stone ; and 

 Lower Jurassic. ..... . 



some of the close hard silicious grit bands, though 



diiSeult to trim or dress fine, would afford a very lasting material for rough 



work. Limestones in this group also furnish good black or gray or 



orange stone, the former procurable from the Lodye and Joorun range 



near Hubbye or the Juria hiUs, north by west of Bhooj, and the latter 



occurring in quantity at Raimulroo hill near Kaora, and in several other 



places in the Putchum chiefly along the Kala mountains. 



In the Putchum also and at other points of the Eunn Island chain, 



some thin-bedded red or yellow calcareous rock largely composed of 



broken shells is found. This takes a good polish and has received the 



name of Dokawana marble ; thin layers of it occur in other parts of 



the district also in the lower Jurassic rocks.
