A still higher yield than can be expected by the 

 use of any other manure, can be obtained, especially 

 on poor soils, by giving the land a top-dressing of 

 bone-dust or superphosphate of lime in quantities 

 of about four to five cwts. per acre. A more liberal 

 treatment of the soil will not only result in larger 

 yields, but will improve the grain in quality ; and 

 the gluten, the most nourishing portion of it, will 

 increase in the same proportion as the nourishment 

 of the plant increases in the soil.
