that " the new coal mine on the north side of the mountain 

 presents a bed of coal one hu.idred feet thick." "The quan- 

 tity of coal on the land of the company is supposed to be 

 equal to a four equal-sided prism of five hundred f et on each 

 side, and seven miles in i- gth ; the largest body of coal 

 known." 



There can be no doubt that this coal will become an ob- 

 ject of vast national importance. It is a verv pure anthra- 

 cite, but sufficiently combustible, in. a proper apparatus, n 

 with proper treatment, to ma\nldi'iu a constant and (if desired) in- 

 tense fire, which burns without odour or smoke — is perfectly 

 safe although left for the night and without watching, will con- 

 tinue till morning, and will then be found in a state of sufficient 

 activity. It is admirable for halls, churches, and other similar 

 places, where it is desired to throw into circulation a large 

 volume of warm air ; and we have it on the best authority 

 that it is excellent for the smith's forge, and for her ^>ur- 

 poses of the arts. — Ed. 



15. Mineralogy of the coast of Labrador, and of the 

 shores of the St Lawrence. A gentleman who lately return- 

 ed to this city from the Labrador coast, and whose attention 

 has been successfully turned to the Mmeralogy of the Gaspe 

 district, from which some very valuable and beautiful speci- 

 mens of the quartz family, particularly the different varieties 

 of cornelian, agate, opal, and jasper, have been introduced 

 into the province, and cut into diflferent ornamental articles' 

 by Mr. Smillie, Lapidary of this city, brought up some 

 beautiful specimens of the sky-blue variety of the Labrador 

 feldspar, a mineral first, and as yet almost exclusively, found 

 on that coast. The others and alaiost all the different 

 varieties of this mineral, it is stated, are found on the same 

 coast : viz. green, yellow, red, and pearl gray ; the present 

 specimen, as seated above, is of the blue ; it is hard, and 

 takes a fine polish ; the changeability of colour, from a dark 

 gray to the most bright and vivid skv-blue, is beautiful, and 

 makes it very valuable, and well adapted for cutting into 

 snuff-boxes, ring-stones, &.c. 



The specimens alluded io were found at Mingan, and 

 appear to be imbedded in a gray granitic rock.
