the Devonian group. No mollusca, or indeed any fossils, are 

 found in the limestone, which is made up of a mixture of the 

 blue and gray varieties, highly metamorphosed by heat, and 

 much disturbed in their stratification. Masses of sienite, con- 

 sisting of flesh-colored feldspar and hornblende, without much 

 quartz, are observed at Indiantown, and are rocks of igneous 

 origin. 



All along the Kenebekasis River, are observed red sandstones 

 of the old red or Devonian group, and at Sussex Vale we come 

 to the celebrated Salt Springs, which rise from the Saliferous 

 Sandstones, and produce, by evaporation, the finest and most 

 agreeable table salt. 



In Hillsboro, we find the lower members of the coal series, 

 so remarkable for the abundance of fossil fishes, of the genus 

 PalcBoniscus, and for that highly bituminous variety of coal, 

 which has been called Albertite. This group of strata, with its 

 fauna and flora, were formerly described before this Society. 

 Hills of snow-white gypsum, and some extensive beds of Anhy- 

 drite, occur in Hillsboro, and in other parts of Albert County. 

 Naptha springs also exist near the shores of the Peticodiac River, 

 and Petroleum floats on the surface of the waters that arise from 

 them, and is deposited as a soft bitumen among the grass roots, 

 and in the soil ; it being left in its thickened and oxidized state by 

 the water, as it periodically rises and falls with the seasons. 



On reaching the mouth of Chepody Bay, we come to Mary's 

 Point, and Grind Stone Island, where beautiful buff'-colored, 

 and light red Sandstones of the Carboniferous group, are quar- 

 ried for building-stones, and a blue variety of the same forma- 

 tion, which is used for making grindstones, is found. At this 

 time, the St. Mary's Point quarries present a scene of unwonted 

 activity, owing to the enterprise of Mr. Archibald, who has em- 

 ployed upwards of seventy-five quarrymen, under the directions 

 of Mr. George Lang, in quarrying out the freestone for archi- 

 tectural uses. These sandstones are found to be of excellent 

 quality for building purposes, and are now largely imported 

 into the United States, under the cegis of the reciprocity treaty 

 between the United States and Great Britain. Mr. Alger has, 

 on a former occasion, demonstrated the durable nature of this
