ore which does not contain frequent deposits of that wliich 

 we are discussing, I cannot say in what quantity it is found 

 iu tliis spot, but as Mr. M. found it thickly scattered 

 throughout the whole depth of eight feet, it must be 

 tolerably abundant. He also informs me that there is ore, 

 which upon examination appears to consist of dcconipusing 

 epidoteand magnetic iron, this is freijuently noticed among 

 the bog ore, a fact of importance, as it seems to indicate 

 that the magnetic iron of this locale is in some abundance. 

 The last mentioned ore is very easily fusible, and is found 

 to improve the working of the furnace. 



I'HIRD OIIK BED. 



At the western extremity ot Crow Lake, in the township 

 of Belmont, about four miles from the works, there is 

 another deposit of magnetic iron, forming a blufV on the 

 left hand shore. From hence the main supply has been 

 obtained for carrying on the works. Its quantity appears 

 to be almost inexhaustible, but tlie quality of much of it is 

 not by any means so good as that before described, being 

 mineralised by sulphur and e|)idote. There is, liowever, a 

 large jiortion very good, which from that circumstance and 

 the ease with which it may be procured and broken up, is 

 at this moment the favourite ore. What this ore bed may 

 low with res()ect to the per-centagc of metul it may yield 

 when compared with the other, it much more than recovers 

 by the facility with which it may be i)r()ctu-ed — the ore boat 

 arcomjKiiiH'd Inf two cr three men pntv'nled irith a vii'dxe, 

 thovel, (itid siedge hammer, may f^o to this bed in the tnuni' 

 ing and return in the evening with fifteen tons of ore. 



Mr. Manahan has noticed that the ore frum this bed 

 rejected on account of its containing too much sulphur, 

 doe«, in the course of two years or thereabouts, become
