28 HOW ox MINERALS FOR THE PARIS EXHIBITION- 



Like the Teuy Cape ore, it is in clean samples, very free of 

 iron. 



PAINT STONE. 



Umber forming rock, from East Mt. Onslow, by Robert 



Murray, Esq. 

 Paint and cement stone, from Chester Basin, by W. Suther- 

 land, Esq. 



These paint stones are very interesting rocks. The Chester 

 stone I have lound to consist of lime-stone, impregnated with 

 carbonates of iron and manganese, which, by exposure to 

 weather, becomes changed to hydrated oxides, and afford 

 umbers of characteristic colours, which form admirable paints. 

 The Onslow umber has no doubt a similar origin to that from 

 Chester Basin. The Chester stone has been found to yield 

 excellent cement. Specimens of this are to be seen at the local 

 exhibition. 



Large samples of red, vjhite and variegated Plaster, from 

 Antigonish Harbour. 



In addition to these there has been sent 

 A collection of rocks, minerals, ores and fossils, with maps 

 and sections illustrating the Geology of Nova Scotia, 

 by Dr. Honej^man. 



In this collection the minerals will be shown in their relation 

 to the rocks in which they are found, so that their mode of 

 occurrence will be illustrated, and a most interesting stud}'" will 

 be afforded to geologists and mineralogists. In speaking now of 

 the minerals which remain and will l^e on view here, I will pre- 

 serve the order in which they will be seen by visitors. In the 

 first place will be observed the "collection of gold nuggets, 

 and auriferous quartz from the various gold fields of Xova 

 Scotia, prepared by P. S. Hamilton, Esq., Chief Commissioner 

 of Mines. It is accompanied by a gilt pyramid, representing 

 the bulk of the gold extracted in N. S. from Jan'y. 1st, 1862, 

 to Sept. /30th, 1866, as per official returns. The Aveight of
