The sectional area in 1915 was 87.54 square feet; practically 

 identical with that of 1908, before the thinning was made. In 

 eight growing seasons 160 trees had added a sectional area equal 

 to that of the 598 trees taken out. 



The following note on "Cutleqf" Chestnut is furnished by Prof. 

 Retan : 



In 1908, a thinning was made near "Orebank Eight" on the 

 Mont Alto Forest in Pennsylvania. In 1913 to 1914a permanent 

 sample plot was laid off in this area and underplanted. While 

 collecting growth data in 1915, one of the students called my 

 attention to the peculiar leaves of a chestnut sprout. Two or 

 three of the sprouts of one stool bore leaves very deeply cleft. 

 The leaves resembled those of such varieties as the cut leaf maples 

 and birches. The sprouts were about four or five feet high, and 

 rather dense around the stool. 



At the time, it seemed possible that it was only a freak and no 

 especial attention was paid to it. But on returning to the plot 

 this simimer (1916), it was found that the sprouts again bore the 

 same peculiar type of leaf. The other sprouts of the stool were 

 cut away and the sprout showing the most marked variation will 

 be favored to ascertain if the variation be permanent, or if it be 

 only a result of the limited food supply. 



The advocacy of municipal forests is bearing results, some ten 

 cities can now be named in the United States having mimicipal 

 forests, aggregating aroimd 150,000 acres, and it is probable that 

 altogether 250,000 acres are under such ownership; the largest 

 perhaps is that of Newark, New Jersey, with 22,000 acres. Hart- 

 ford, Connecticut, owns 4,000 acres; Fall River, Massachusetts, 

 around 4800, of which 1550 acres is fit for planting, while the 

 Metropolitan Water Board of Boston has planted about 1800 

 acres of its reservations.
