This material is essentially carbonate of lime, and if crushed or powdered, could 

 be used effectively as an amendment for all soils in need of lime. It should 

 prove of particular value for the heavy soils mentioned by our correspondent as occur- 

 ring in the neighbourhood. 



Laboratory Nos. 12351-2. — These are samples of crushed limestone from English 

 quarries, submitted for analysis by a Canadian correspondent who states that these 

 limestones could be purchased for export at about 50 cents per cask of 400 lbs. and that 

 the ocean rate would be about $3.50 per ton.

As regards lime content there is little difference between these samples; both are 

 of excellent quality. As an agricultural source of lime, however, their use would be 

 prohibited by reason of their high cost to Canadian farmers. 



Laboratory No. 13753. — Marl from bed at Lower West River, Antigonish Co., N. 

 S., in powder and lumps of rock fragments and has the appearance of weathorod and 

 disintegrated limestone.

It is essentially carbonate of lime, and if reduced to powder would assuredly 

 prove a valuable amendment on soils requiring lime.
