Between Montreal and Saiit au RecoUct. 2S5 



About a French mile from the town are 

 two lime-kilns on the road. They are built 

 of a grey lime-ftone, burnt hard, and of 

 pieces of rock-ftone, towards the fire. The 

 height of the kiln from top to bottom is 

 feven yards. 



The lime-ftone which they burn here. Is 

 of two kinds. One Is quite black, and fo 

 compact, that its conftituent particles can- 

 not be diftingulfhed, fome difperfed grains 

 of white and pale grey fpar excepted. Now 

 and then there are thin cracks in it filled 

 with a white fmall-grained fpar. 



I HAVE never feen any petrefadlions In 

 this ftone, though I looked very carefully 

 for them. This flone is common on the 

 ifle of Montr ealy about ten or twenty 

 inches below the upper foil. Jt lies in ftrata 

 of five or ten inches thicknefs. This flone 

 is faid to give the beft lime ; for, though it 

 is not fo white as that of the following grey 

 lime-flone, yet it makes better mortar, and 

 almofl turns into ftone, growing harder and 

 more compa6l every day. There are exam- 

 ples, that when they have been about to 

 repair a houfc made partly of this mortar, 

 the other ftones of which the houfe conlifts, 

 fooncr broke in pieces than the mortar it- 

 felf.
