trees during that period was extremely variable, but 

 the following gives a fair average: From 1,150 trees 

 at Canterbury, in Vermont, 618 barrels of sap, or 

 1 9*777 gallons, were obtained, from which was manu- 

 factured 4,000 pounds of sugar, or one pound of sugar 

 per five gallons of sap. On the other hand, in Cam- 

 bridge, Vermont, from 75,730 trees 221,350 pounds of 

 sugar were made, or an average of about three pounds 

 per tree. Upon this basis we beg to make a small 

 calculation, showing the number of trees that must 

 necessarily be planted to furnish all the sugar we 

 consume in the United States. The consumption 

 was, in 1877,* 1,692,299,758 pounds. The number of 

 maple trees to furnish this would be 564,066,583. It 

 is admitted that two men can, in the season, take care 

 of three hundred trees, or one hundred and fifty trees 

 per man, consequently for the tapping of the trees 

 alone it would require 5'^--f |^5.o =3,760,443 men. If 

 the boiling and the preparing of the sugar for market 

 (in and out of the factory) should require, say, as many 

 more hands, the total number would then be over 

 7,OOO,OOO men, or nearly every available working man 

 in the United States. This very idea prevents one 

 from looking to the maple tree as a source for home 

 sugar supply. 



Home Production of Maple Sugar. 



The following table gives the home production of 

 maple sugar, which shows that in 1877, 1,000,000 

 pounds less were produced than in 1861. As maybe 

 nticed in table showing the production in various 

 States in the Union, with the exception of Illinois 

 with an increased average production in ten years 



* The calculations were not based upon the consumption of 1880, for the reason 

 that we received the data a few days only before going to press.
