which show that the mass consisted chiefly of pyrolusite. That the 

 associated mineral was psilomelane follows from its appearance and 

 hardness, the colour of its powder, and the amount of water contained, 

 which is too little for manganite, and too much for any of the other 

 manganese minerals." 



" It is an interesting fact that silver, to the amount of five ounces 

 to the ton of ore, has been found in a specimen from Teny Cape, on 

 assay by J. Taylor and Co., in London." 



The deposit of manganese ore on the property of the " Onslow East 

 Mountain Manganese and Lime Company " occurs under similar geo- 

 logical conditions with that of Teny Cape, and has been very favourably 

 reported on, both as to the quantity and quality of the mineral, by 

 Mr Barnes, Professor How, and Dr Honeyman. 



Galena, or sulphuret of lead, is found in disseminated crystals and 

 small veins in limestone at Gay's River and some other places. Some 

 specimens which I have examined contain a considerable proportion 

 of silver; and one bed of limestone at Gay's River, pointed out to 

 me many years ago by the late Mr G. Duncan, has so much dissemi- 

 nated galena that favourable opinions have been expressed as to its 

 economic value ; but I am not aware that it has yet been worked. 

 The occurrence of valuable ores of lead in the Lower Carboniferous 

 limestones in England and other countries gives some reason to hope 

 that more important indications of this metal may yet be discovered. 

 Sandstone suitable for building purposes occurs at Horton, Halfway 

 River, Windsor, the Shubenacadie, and probably many other places ; 

 but not in such quantity nor of such excellent quality as in the Coal 

 formation of Cumberland and Pictou. For this reason it may not, 

 for some time at least, be worthy of attention as an article of export, 

 but it can be abundantly obtained for domestic use. 



Clays suitable for bricks and common pottery can also be procured 

 in large quantity on the Shubenacadie. Yet in the last census Hants 

 made no return of bricks, while the quantity made in Colchester was 

 stated at 420,000. 



Coal in small seams occurs at Salmon River, North River, Chiganois
