26 D GEOLOGICAL SURVEY OF CANADA. 



without finding any trace of the mineral sought. The most extensive 

 operations have, however, been carried on by the Beliveau Mining 

 Company. At Beliveau a shaft has been put down to the depth of 200 

 feet, and tunnels driven north and south across the measures, without 

 finding anything of importance. Borings were then begun at Taylor- 

 ville, about one mile to the east, since which we have not visited the 

 scene of operations. Eeports, however, do not indicate any great 

 measure of success. 



Gypsum. 



Gypsum occurs at various points both in Albert, Westmorland and 

 St. John counties ; the deposits of Hillsborough have been described in 

 the report of 1876-77, since which new openings have been made at 

 Hopewell Hill, where a splendid deposit of the fibrous variety occurs. 



At Fawcett's Brook, about two and a half miles north-west of Petit- 

 codiac station, a large deposit of the fibrous variety is found, which 

 has been locally worked for agricultural purposes for some years. The 

 quality is excellent, and the deposit should be of considerable value. 



Granite. 



The granites of Charlotte county, at many points, afford abundance 

 of excellent stone for building and polishing, but the quarries near St. 

 George, on the Magaguadavic Biver, are as yet the only localities which 

 are worked. Full descriptions of these, with the polishing works, are 

 given in the report of 1876-77, page 346. 



Infusorial Earth. 



Deposits of this substance are found occupying the bottoms of lakes 

 in several places. Among these were specially noted two in eastern 

 Kings county — Pollet Biver Lake, in Mechanic settlement, and Pleas- 

 ant Lake, about six miles to the south-west. The deposit in Pollet 

 Biver Lake is said to be about four feet deep, and the earth is exceed- 

 ingly fine, of a greyish-white colour' when dry, and admirably suited 

 for polishing the finest substances. The lake can be easily drained, or 

 the substance can be removed with a shovel or small dredge.
