BULLETIN" 466, U. S. DEPARTMENT OF AGRICULTURE. 



From this it is seen that the figures for the Beauce district are a 

 little higher than those for the other two districts, the region below 

 Montreal giving the lowest figures and that above Montreal the next 

 lowest. This is apparently the direct opposite of the tendency of the 

 sugar sirup of the United States. 



EFFECT OF ENVIRONMENT ON THE COMPOSITION OF MAPLE SUGAR. 



In the case of sap sirup, there is a relationship between the loca- 

 tion of States and the composition of the product. Taking the 

 average determinations for the States and localities in some of the 



Fig. 1. — Map showing effect of environment on analytical results of maple sugar, Canada. 



States, as one goes north there is a lower figure for total ash, lead 

 number, and malic acid value. Tabulating the results of the maple 

 sugar work in this way, the same general tendency is noted.
