weigh about one pound, being of a daik-green color, translucent only 

 on the edges. One of its planes was penetrated by an octahedron of 

 grey pyroxene. The white variety attains even a much larger size, 

 and crystals as large as a cricket-ball may be frequently met with. 

 On the next lot, 7, a garnet aj)parently containing much more iron, fus- 

 ing to a black^glrtss, occurs in a band of disintegrating limestone, and, 

 like the latter rock, is rapidly losing its cohesive properties A portion 

 of a large crystal obtained near the surface could not have weighed 

 less than five pounds originally. Its color is nioi'e of a brownish tinge, 

 and it is seldom as bi-ight in lustre. A peculiar white scaly variety 

 in crystalline masses, more or less mixed wich a serpentinous min- 

 eral (its line of contact being often difficult to discern) occurs in close 

 connection with the above. It sometimes exhibits one or more I'ough 

 faces, which are invariably altered to a steatitic mineral. 



Chrome Garnet. — Beautiful little dodecahedrons of this mineral 

 occur in small gi-oups, or attached crystals, in a fine granular grey 

 pyroxene, on lot 29, in the 4th range of the same township. 



Zircon. — Fine specimens of this mineral have been fouad at vari- 

 ous times during the develo})ment of the apatite deposits in the above 

 townships. A crystal 15 inches in length is said to have been found by 

 a miner on lot 23, range 13, of Templeton, who, being doubtful of its 

 nature, broke it up to satisfy his inward curiosity. You may imagine 

 the poor man's feelings when he was told that he had just let slip 

 thi-ough his fingers $200. One crystal preserved from this locality, 

 now in the possession of Mr. J. G. Miller, measures four and a half 

 inches laterally and one inch aci'oss the faces. Another crystal from 

 Gemmill's Mine in Wakefield is said to be six inches in length. Small 

 crystals may frequently be found in calcareous portions of the pyroxene 

 rocks. On lot l-i, range 1, of Wakefield, crystals from a quarter to an 

 inch in length occur in a thin layer of shaly limestone that is intercal- 

 ated between beds of woUastonite. At Haldane's Mine, in the same 

 township, minute pink semi-transparent prisms occur in pyroxene. 



Idocrase. — Handsome crystals of this mineial are found in Tem- 

 ])leton and vvakefield. Brownish-red slightly modified prisms, an inch 

 in diameter, occur on lot 7, range 12, of the former township, and on 

 lot 14, range 1, of Wakefield, brownish and greenish ])risms often over 

 an inch in diameter, occur in a woUastonite lock.
