A list of companies in New York State producing ground lime- 

 stone or marl for agricultural use is given below. 



Ground limestone of good grade (the total passing a sieve with 

 ten meshes to the linear inch, and containing at least 90 per ct. 

 carbonates) can be obtained in bulk, carload lots, f.o.b. quarries, 

 at $1 to $2 per ton. The added freight charges make this $1.50 

 to S3 per ton delivered to the farmer's railway station. For most 

 soils in this state ground limestone should be used in liberal quantities, 

 and its cost ought not to exceed $3 per ton including freight. In 

 the greater part of the state it can be obtained for much less.
