FOODS HUMAN NUTRITION. 267 



Comparison of sirups from sap collected iu covered aud uncovered buckets 

 stiowed that the difference in color was sliglit but that " the ash content of the 

 sirup from the uncovered budgets is greater than from the covered ones. This 

 increase occurs in the soluble ash, as there is only 0.04 per cent difference iu 

 the insoluble ash of the two samples." 



The author points out that some of the constituents of sirup decrease as the 

 more northern latitudes are reached. " In general, this is true of the total ash 

 and the lead number and to a less degree of the malic acid value. There are a 

 few exceptions to this general tendency whicli may be due to the altitude of the 

 sugar bush, to the soil, or to the exposure. 



" Soil data were collected from the individual makers, but on compiling them 

 no distinctions that would admit of any classification wei'e found. No doubt 

 the kind of soil on which the bush is located influences, to a slight extent, the 

 ash content aud possibly the malic acid value and lead number. Also sirup 

 made from soft and that from hard maples in the same locality might show 

 very distinct differences. The few samples of soft maple sirup collected are 

 hardly sufficient to afford any basis of comparison." 



The bulletin also includes a summai-y of statistics of the maple-sugar industry 

 in the United States, and a bibliography of the general subject of maple sugar.
