LIME. 



Limestone fitted for burning is found in great 

 abundance in most parts of the champaign region, as 

 will be seen when we come to speak of building 

 stones. The use of lime as a fertilizer for many soils 

 is well known, and for this purpose the greater part 

 of the limes in the province, on account of their 

 freedom from magnesia, are well fitted. About 

 270,000 bushels of lime are annually burned at Mon- 

 treal, where its price is about seventeen cents (eight 

 pence half-penny sterling) the bushel. Limestone is 

 less abundantly distributed in the mountainous 

 districts of Canada, where however geological 

 research has shown its presence in very many loca- 

 lities, especially in the Laurentian country, where 

 bands of limestone have been already mentioned as 

 marking the. course of numerous fertile valleys. 

 Limestones are also found in many parts of the 

 Eastern Townships. 



The property of forming a mortar which will 

 harden under water, which belongs to hydraulic 

 cements and water-limes, is possessed by the lime 

 yielded by many limestones in the country, as at 

 Quebec, at Hull on the Ottawa, at Thorold near Nia- 

 gara, and at various other places in the western 

 peninsula. Materials from these sources have been 

 used in the construction of the extensive hydraulic 

 works of the province. 



BUILDING STONES. 



The abundance of good building stones in Canada 

 is so great that it is easier to say where they are not 

 found than to indicate their various localities. 

 Quebec, Montreal, Ottawa and Kingston are built of 

 a grey limestone, which is quarried in their imme-
