HOW ON ORES OF MANGANESE AND THEIR USES. 133 



barrels of ore were on one occasion dug up in cultivating a garden 

 at Walton ; of the quality of this I know nothing, but that 

 valuable ore is found at Walton I am certain inasmuch as a party 

 of which I was one extracted several pounds at a locality in the 

 woods about seven miles from Teny Cape ; one piece of this is 

 sent to the Dublin Exhibition, and is quite as rich to all appear- 

 ances as that from Teny Cape.* About twelve miles south of these 

 places Mr. Mosher has met with large detached pieces of ore, one 

 weighing thirty-five pounds was sent to the Exhibition of 18G2 

 and remains in England; it consisted of pyroliisife and jmlomelane ; 

 it gave to Mr. Poole, one of my pupils, about 84-5 per cent, bin- 

 oxide; another lars^e mass found in the same rearion weio-hed one 

 hundred and eighty-four pounds. I do not know of what kind of ore 

 it consisted. The rock holding the manganese at Teny Cape is a lime- 

 stone containing a good deal of magnesia, and colo.iu'ed either grey 

 or red by oxide of iron; it is soft and easily detached from the ore; 

 barytes is frequently seen crystallized through the ore, and carbon- 

 ate of lime (calcite) is sometimes found beautifully crystallized in 

 various forms encrustmg the ore. At Walton the manganese is 

 sometimes associated with iron ore (limonite), and occurs in lime- 

 stone. Since nearly all the localities mentioned in a previous page 

 as affording manganese are of lower carboniferous age, it is not 

 improbable that many others may yet be found in the Province, 

 where rocks of this age are so abundantly distributed. It is not, 

 however, in such rocks only that manganese may be expected, 

 since it appears by the Report on Mines and Minerals of New 

 Brunswick, by Prof. Bailey, issued in 1864, that the deposits of 

 manganese, with one exception, in that Province, are met with 

 either in lower silurian or cambrian rocks (p. 71); the exception is 

 a bed said to be alluvial (p. 33). As regards the mode of occurrence 

 it is stated (p. 72), that manganese is generally found in quartz or 

 barytes, es^^ecially the latter, the country-rock being slates ; at one 

 locality (p. 45) the slates enclose a bed of limestone, three or four 

 feet thick, which contains the manganese ; the allu\ial locality is 

 also said to have the manganese in limestone ; in all cases the 



* Five tons were afterwards taken out here by Mr. .J. Browne. 



t In a report issued in 1865, and received since this paper was read, I iind that 

 Professor Bailey places the manganese localities in New Brunswick at the base of tiie, 

 lower carboniferous series.
