288. The extent of these deposits has not been traced so recently 

 to the westward, but no doubt is entertained, that they attain there also 

 an equal extent, judging from the recollection of former journies. Below 

 Nahun in particular, and near Munta Dihee, at the exit from the 

 Pinjore Doon, very clear traces of them are to be seen. That the 

 Pinjore and Kyarda Doons are, equally with the Dehra Doon, composed 

 of them, I have no doubt. It ought to be stated, before concluding, 

 that in the Dehra Doon, the great thickness appears to be in the 

 centre where the ground is highest. Towards the vallies of the Ganges 

 and Jumna, they diminish very much in thickness, and in the beds 

 of those rivers, may be observed resting on sandstone. 



289. Southward of these rounded stones, a very extensive deposit 

 of the red clay, which is very similar to the red strata of the sandstone, 

 prevails. It has often small patches of loose sand. This red gra- 

 velly clay lies in a blackish clay of a purer character, very stiff and 

 tenacious at different depths in different places. This latter ap- 

 pears to change to a lighter colour as we descend, and becomes more 

 arenaceous, till at length it changes to a grey sand. My enquiries 

 and observations have not yet been sufficiently general to allow me 

 to identify these deposits with any thing like certainty, indeed it is only 

 very lately I have been able to turn my attention to the subject, and the 

 recent arrival of the boring engine I had ordered from England, pre- 

 cluded the possibility of constructing a proper apparatus and scaffolding 

 for using it with effect, unless the operations were delayed till the ensuing 

 year. I was therefore obliged to content myself with such results as could 

 be obtained without the proper means, and was not able, in consequence, 

 to penetrate beyond twenty-two feet in any of the bores I made ; but 

 I hope on my return to the field duties, that I shall be able to continue 

 these enquiries with greater effect. 



290. In the meantime, it may be interesting to give the particulars of 

 the few bores I made. The first was at Moradabad, but being new 

 to the operation, it took several days to bore sixteen and a half feet, 

 the particulars were as follows : — 



Feet. Inches. 



4 Superficial sandy loam forming a very productive soil. 

 2 5 Brick earth. This is the red clay, which prevails so exten- 

 sively in Rohilkund, and which so often comes to the
