this base well-rounded pebbles of quartz are thinly scattered, seldom 

 larger than a hen's egg. These pebbles are sometimes so scarce as 

 easily to pass unnoticed without special search. In most places sub- 

 angular fragments of a slate rock are the prevailing foreign elements 

 in the conglomerate, which thus assumes a very brecciated aspect. 

 The whole appearance of this rock is often that of a trapash. It 

 is frequently thick-bedded, sometimes massive ; its total thickness 

 varies from ten feet to one hundred, or more in some obscure 

 sections. I have traced it from the Blini to Naini Tal. I will call 

 this conglomerate and its attendant limestone by the name of the 

 Blini group. From the source of the Blini river to its confluence with 

 the Ghumber these rocks are never far off, and in many places 

 they crop out across or along the river. As an irregular accompani- 

 ment of these Blini beds I must mention a clear coarse quartzite : at 

 two or three points in the lower course of the Blini this bed shows 

 apparently over the limestone. It may elsewhere assume a greater 

 development. 



The bend that the Blini river takes, from the longitudinal band 

 of soft nummulitic rocks, through which it flows at first, across the 

 general strike of hard rocks, under the north-west base of the Krol, & 



enables us to see most unequivocal evidence of the true position of 



these Blini beds as regards the Krol group. In 

 Section in Blini river. 



the valley west of Solun the Blini limestone 

 shows at several places at and near the boundary of the soft nummu- 

 litic rocks. In the transverse gorge of the Blini stream the same beds 

 are several times exposed crossing the stream; and again, along the 

 lower valley of the same stream to its confluence with the Ghumber 

 the course of the Blini beds is about coincident with that of the river. 

 The Blini group seems to be underlaid by the same kind of rocks as 

 those overlying it. In every section that I have seen (and they are very 

 numerous), exactly the same description of thin, shaly slates, and «rits
