Parts of the vein contain notable percentage of Manganese. 

 The Limonite has a very fine variety of the Red Haematite mixed 

 with it at several points, at one place the Limonite appears to be 

 replaced by it for some distance. The ore is of a deep red colour 

 and of the finest quality, containing but a small admixture of foreign 

 matter. As yet it is known only in small quantity in the form of 

 surface boulders, but would amply repay a careful search for it. 



About one mile to the West of the East River we meet the Spe- 

 cular vein. This is a very pure anhydrous peroxide of iron, having 

 a metallic lustre and steely black colour. This vein has been 

 carefully examined and traced on the properties of the Pictou Coal 

 and Iron Company, where trenches and pits have shown it to extend 

 over two miles, — its width varies from five to twenty feet. The 

 vein follows the course of a high hill and is accessible by levels at 

 several points. At one or two points a side vein, two feet wide, 

 contains Magnetic oxide ? and Limonite of a nearly black colour. 

 I believe Dr. Dawson considers this vein to belong to the same 

 Geological horizon as that holding the Londonderry ores of Colches- 

 ter County.
