ACKNOWLEDGMENTS 



In preparing this work the author used as a groundwork Bulletin 

 No. IB., "Maple Sugar and Syrup," published in 1907 by the Depart- 

 ment of Agriculture. To the information taken therefrom, which has 

 been almost entirely re-written, there has been added much new matter 

 gathered up during the course of a tour among sugar makers at work 

 in their groves in the Spring of 1913. Credit must also be given to 

 publications of the Vermont Maple Sugar Makers' Association, to 

 proceedings of the Pure Maple Sugar and Syrup Co-operative Agricul- 

 tural Association of Canada and to Farmers' Bulletin No. 516 of the 

 United States Department of Agriculture, "The Production of Maple 

 Syrup and Sugar." 



Most of the photographs reproduced were taken by the author; but 

 for others grateful acknowledgment is due Prof. E. J. Zavitz, Forester 

 of the Department of Lands and Forests, at Toronto, who supplied 

 the originals of the front cover half tone and the frontispiece. Thanks 

 is also due the Grand Trunk Railway System for the use of scenes 

 depicting sugar making in the Algonquin Park, while Canadian manu- 

 facturers of modern equipment kindly supplied illustrations of their 

 machines and implements.
