74 Geology of the Country [Feb. 



appearance being hornstone crystals imbedded in lime. The garnets 

 in the mica slates are, as far as I have ascertained, all imperfect, soft 

 and ochrey colored. 



The limestone specimens 5 and 7 occur very generally along the 

 ■west of the road, and 7 forms a hillock by the side of a nullah about 

 15 feet high, irregular and steep; 6 and 8, specimens of micaceous 

 limestone or of mica schist and limestone passing into each other, are 

 found in the banks and beds of nullahs. 



10 forms the top of a small hill west of the road near the end of 

 the pass towards Putroda ; it appears to repose on a substratum of 

 mica slate. 



The specimens marked D, are from the neighbourhood of the Hathee- 

 Doab hill and pool. 



D 1 . — is the limestone burnt for use for the works at Hoshungabad. 



D 2. — is an abundant rock extending E. and W. and up the road to 

 Baitool. 



The Nos. 6, 7, 8, 9, form the hill of Hathee-Doab ; G forms the base, 

 and 8 the summit of the hill. 



D 1, 2, and 4. — Compact limestones found on either side of the 

 Hathee-Doab hills ; the quartz, 3 and 6, are scattered about on the road 

 to Hathee-Doab ; 5 forms the foot of the hills, 9 and 10 are loose speci- 

 mens met with here and there. 



5th Division. — The 5th division extends from Putroda to the 

 Nerbudda at Hoshungabad. 



After passing through the hills a rich field of cultivation opens to 

 view, and the rocks are lost under the deep alluvial soil of the valley of 

 the Nerbudda. South of the river two insulated mounds of new red 

 sandstone, rising abruptly from the plain about 1^ miles from canton- 

 ments, are the only rocks which show themselves on this side of the 

 river, and they are shoots from the northern or Vindya range which, op- 

 posite Hoshungabad, are of this formation. 



In excavating two wells of the depth of about 70 feet at Hoshunga- 

 bad, no rock was met with, but the coarse calcareous conglomerate com- 

 mon in the bed of the Nerbudda. 



At the junction of the Towa river with the Nerbudda, 4 miles 

 above Hoshungabad, sandstone ridges cross the river, and 60 miles 

 below, at Hindia, the river is traversed by a basaltic dyke, and the inter- 

 mediate rapids between those two points are formed of sandstones and 

 coarse conglomerates, rising in some places several feet above the level 

 of the river ; opposite the cantonments the bank is formed of the con- 

 glomerate, and has all the appearance of the ruins of old uncoursed rub- 

 ble work, E.
