REPORT OF THE DIRECTOR I917 91 



By frequent and numerous drillings and trenchings, the manganese 

 area was delimited to a patch 130 feet in length by 50 feet in width, 

 approximating 6500 square feet in area. Under this area to a depth 

 of ii feet bog manganese occurs in greater or less amounts largely 

 as nodular wad with only a slight local development of nodular 

 aggregates. 



Allowing 235 pounds of sand, clay and manganese to the cubic 

 foot and 50 per cent of the volume as consisting of bog manganese, 

 this bog should yield approximately 450 tons of wad. 



According to Mr Mather, " a bed of wad or earthy oxide of man- 

 ganese has been found on the farm of Joseph Goodsell in Hillsdale." 

 Mr Calvin Prescott dug 50 tons of the ore some years ago and sold 

 it for $20 a ton in New York. As Mr Joseph Goodsell at the time 

 this record was made owned four farms not adjacent, the manganese 

 bog in question was located with much difficulty. It was found to 

 be 3 miles northeast of Crearyville and the same distance northwest 

 of Hillsdale. 



A narrow east- west open and stony black muck bog or " run " 

 about 450 feet long with an average width of 25 feet was found just 

 west of the old Joseph Goodsell farm. As in the other description of 

 bogs, this occupied a small divide between two hills at an elevation 

 of 1200 feet above sea level, from the eastern end of which a small 

 brook was flowing. The bog was found to contain numerous man- 

 ganiferous nodules at the western half and an intensely black, earthy, 

 manganiferous muck throughout the eastern half. The nodules 

 varied in size from that of small shot to larger diameters. Limonite 

 nodules were found sparingly. Manganese dioxide was present in 

 the form of cement which consolidated the local areas of boulders 

 and clay. An occasional fragment of nodular aggregate consisting of 

 clay and wad was found. 



One of the most interesting occurrences of manganese was noted 

 here in the form of a bluish black iridescent scum surfacing a few of 

 the small pools of water in the bog proper, not unlike the yellowish 

 green iridescent scum associated with iron springs. This scum may 

 well be one of the manganese minerals similar to the iron scum and 

 originating as a result of bacterial action. 



The percentage of manganese in this bog is higher than in all the 

 others, averaging about 22 per cent. 



With a surface of 10,750 square feet and an average thickness of 

 1 1 feet, allowing one-third of the volume for bog manganese, the 

 writer estimates that there is approximately 600 tons of bog man- 

 ganese in this locality.
