the hill. There are vesicular hands which may be the surfaces of flowSj 

 but they are not very distinct. 



West of Sitabaldij a thin argillaceous intertrappean band may be 

 traced for some distance along the scarp which 

 runs parallel to the road from Sitabaldi to 

 Telingkhedi, and bounds the valley of the Nag to the north. This 

 bed disappears, apparently by thinning out, at both ends, to the east 

 near the station of Sitabaldi and to the west near Phultala or 

 Telingkhedi tank. It is probable that the thin band on Sitabaldi hill is 

 on the same horizon, and that the two were formerly continuous between 

 the traps now removed by denudation in the Nag valley. North of 

 Telingkhedi the bed is a foot in thickness ; it abounds in shells and 

 remains of plants, and in one place a trap pebble was found imbedded in 

 it; this pebble was much decomposed, and it is impossible to say whether 

 it had been rolled or not. 



This is the locality to which Mr. Hislop's description at pp. 156-157, 

 and his figure 2 in his paper " on the tertiaiy deposits associated with trap- 

 rock in the East Indies," Guar. Journ., Geol. Soc, Lond., Vol. XVI, refer. 

 Calcareous bands traverse the trap in an irregular manner, and are con- 

 sidered by Mr. Hislop to be formed of the intertrappean bed dispersed and 

 scattered by the injection of the igneous rock. Newbold* in a similar 

 case spoke of the irregular bands as "kunkur," and evidently considered 

 them to be due to the deposition of carbonate of lime derived from 

 surface water in cracks. This is my own opinion also ; similar bands 

 are often found near the surface, not only in trap, but in sandstone, gneiss, 

 and other rocks, and that they can scarcely be dispersed portions of the 

 intertrappean bed is, I think, clear from the circumstance that the latter 

 in this locality is not calcareous. 



At the side of one of the small ravines north of the Tehngkhedi 

 road, a band of greenish jaspery porcelain rock, resembling a greatly
