THE SAGAR DISTRICT. 59 



rather sparingly, are imbedded small rounded particles of calcareous 

 spar of a yellow colour. It belongs to the trap, and it is, moreover, ever 

 attendant upon it throughout its range. Near the surface, or where it is 

 in immediate conjunction with other matter, it may be found varying in 

 colour and varying in the quantity of spathose matter. Very frequently, it 

 will be of an, ash colour, and the spathose particles, which are white and 

 thickly set, forms the majority of the mass. Other specimens are red- 

 dish, brick red, deep chocolate, or brownish black ; — others again might 

 be produced, of which it would be difficult to say whether they were 

 limestones or amygdaloids but always in proportion as it is coloured so 

 is it the more clayey, gritty and impure, — ^more affected by foreign matter 

 than that substance, which I have described, as the principal and charac- 

 teristic rock. 



This limestone rock is never found in the valleys, it is confined to 

 the hills, and low swells, and generally forms the basement stratum in 

 them, ascending somewhat above the level of the contiguous valleys. A 

 stratum of this kind, is always sufficiently obvious in a hill possessing it; 

 for along its sides, or at the ends, either a white patch mouldering by the 

 weather immediately catches the eye, — or large rolled and angular pieces 

 stand about, of a greyish colour, and very discernible from the blacker 

 trap ; though the continual line of the stratum, where it juts out to day, is 

 not easily to be distinguished, the knobs, and exposed parts being gene- 

 rally covered with a blackish crust, and also intermixed with masses of 

 indurated trap, and other more earthy matter, debris of the same, slid 

 down from above. A white patch of this limestone, mouldering by the 

 weather, is the source, from whence comes the particles of Jccmker, found 

 intermixed with the black basaltic earth of the neighbouring valley, in 

 such proportion, as to add increased fertility to it; and if a rivulet mean- 

 ders through that valley, and such is generally the fact, patches made up
