kindness of Mr. Rivett Carnao, to exhibit to the Society a very 

 interesting collection of agate flakes and cores found by the late 

 Lieutenant Swiney at Jubbulpoor. A selection from this collection 

 has now been lithographed, for publication in the Society's pro- 

 ceedings. Since last year I have had some slight opportunities of 

 adding to our knowledge of the distribution of these agate implements 

 throughout the country, and I can also state a little from personal 

 observation as to their mode of occurrence. 



" I first met with them at Jubbulpoor. Major Oakes, of the Revenue 

 Survey, and Major Ryder very kindly pointed out to me some of the 

 localities in which Lieutenant Swiney's specimens were found. They 

 appear to abound upon almost every rising ground. I found them 

 here and there near Seoni, and abundantly at several places around Nag- 

 poor. I also met with a few west of Chanda, and, lastly, with two or 

 three small specimens on the trap outlier close to Rajamandry. 



" They appear thus to occur in abundance along the edge of the 

 trap country, which furnishes the stone of which they are composed. 

 They are chiefly found on gentle rises, rarely scattered over alluvial 

 plains. They are frequently to be met with a few miles outside the 

 trap boundary. Whether they occur in equally large numbers 

 throughout the trap area, it is difficult to say ; they have certainly 

 not been found in any quantity as yet. So far the theory which 

 appears best to suit their mode of occurrence is, that men living outside 

 the trap boundary travelled to its edge, in order to obtain the material 

 for their flakes, made what they required on the spot, and threw away 

 the useless cores and the badly shaped flakes. The spots I have 

 indicated, rises near and upon the trap boundary, are precisely 

 those where agates and jasper derived from the traps would first be 

 met with.* - The numbers of the chipped agates, in some places, are 

 astonishing. Lieutenant Swiney must have collected several thousand 

 specimens near Jubbulpoor, and he only took the more perfectly shaped 

 cores, throwing away at least 19 out of 20. The collection I exhibited 

 last year, was only a very small portion indeed of his collection, of 

 which Major Ryder possesses the bulk. I myself obtained several 

 hundreds of flakes and cores from a small hill about 6 miles north of 

 Nagpoor. The majority were not worth taking, as there were only 

 a few faces on them from which flakes had been split, but taken ia
