Report on the Reforestation of Waste Lands in Southern 

 Ontario. By E. J. Zavitz. Ontario Department of Agriculture, 

 1909. Pp. 28. 



The waste areas of Southern Ontario are mostly sand lands, 

 and comprise some 8,500 square miles, in large contiguous areas. 

 The report advises the gradual segregation of all such non-agri- 

 cultural lands to be managed as provincial forests, on the grounds 

 of wood supply, protection of headwaters of water systems, use 

 as game preserves and recreation grounds, and object lessons in 

 forestry. Many areas need only protection from fire, on account 

 of the presence of scrub growth, but calculations are given to 

 show the financial success where planting is necessary. 



A beginning has been made in this direction, the Government 

 having purchased 300 ( !) acres last year. 



The report is extremely well illustrated.
