These samples represent the extremes of composition noticed 

 in our section of the State. The use of Canada ashes has of 

 late steadily increased, anrfl the cost gradually declined to 24 to 

 25 cents per bushel of forty-five to fifty pounds. These are 

 prices by the car-load at Amherst and in its vicinity.
