nearly 96 per cent to as low as 86 per cent. There is a corres- 

 ponding range in sucrose, the sugar of maple, — ranging from 

 nearly 91 per cent to less than 80 per cent. There is fully as 

 great range in the amount of water and solids carried by the 

 sirups. In the case of the sirups there is frequently little dif- 

 ference in the price asked for pure goods and for compounded 

 or blended sirups. If one prefers to use a mixture of maple 

 sirup and cane sirup, it would be much more economical to buy 

 the pure goods and dilute them for one's self. 



The last column gives the estimated amount of maple con- 

 tained in the different classes of goods. This estimate is based 

 upon the lead number which is an arbitrary but reliable measure- 

 ment * for determining the quality of maple goods.
