first discovered here in the river sands 

 and these still afford a small supply. 

 These were first knov^^n in 1867, but in 

 1 87 1 the deposits in place near Kimberley 

 were found and these constitute today the 

 world's great Diamond mines. The 

 mines now being worked are four in num- 

 ber, and all occur within an area hardly 

 three miles square. Geologically the 

 formation seems to be that of a filling of 

 old volcanic necks by an influx of mud 

 from below. It is this mud which now 

 considerably hardened contains the Dia- 

 monds. The largest Diamonds t>f the 

 world have been obtained from these 

 mines, some exceeding the Kohinoor in 

 size. Their quality is also generally 

 good, although sometimes injured by a 

 yellow tinge. 



Besides the above countries, Diamonds 

 have been found in Australia, the Ural 

 Mountains, British Guiana and the 

 United States. The finds have usually 

 been in the beds of streams and are not of 

 sufficient abundance to make systematic 

 mining profitable. The localities where 

 Diamonds have been found in the State 

 of Wisconsin, in this country, are on the 

 terminus of a moraine which came from 

 the North, somewhere in the region of 

 Hudson's Bay. It is hence not improb- 

 able that the "mother lode" will some 

 day be found there. 



Finally it is interesting to know that 

 Diamonds occur in meteorites, and hence 

 doubtless exist in other worlds than ours.

INDIAN SUMMER, 



With your hazv distances. 

 And your fine insistences, 



Of russet, amber, brown. 

 From vv^hat region dost thou journey 

 Hither to our fields a-tourney. 



Flinging thy dim gauntlet down? 

 Dost thou come from Southern seas? 

 Or from mountain fastnesses ? 



Ho, we call thee Indian Summer, 

 O thou late and languid comer. 



Loitering our forest aisles ; 

 Idling with the sunshine dreamy, 

 As with wandering a- weary, 



Chary, ever, of thy smiles. 

 Thou hast come to claim the glamour 

 Of the dear, departed Summer.
