thirty-year-old second growth. In the spring of 1871 and in 

 the spring of the following year, three acres of poor, exhausted 

 meadow in Westmoreland, N. H., owned by Elijah Wyman, were 

 planted at from six to seven-foot intervals. This tract of three 

 acres was sold by Mr. Wyman in 1904 for $350 to Mr. Leon Hall. 

 In 1911 Mr. Hall sold the tract for an even $1,000. 



A stand of White pine established in Switzerland by planting 

 was accurately measured when forty-two years old. The yield 

 per acre was 77 3-4 cords, or an average increment of approxi- 

 mately 1.8 cords. At a stumpage value of $8.50 per thousand feet 

 board measure, which is no higher than in some localities in 

 New England, its value per acre was $9.30. These are only a 

 few of the large yields recorded from plantations of White pine 

 and fully stocked second growth stands. From results already 

 obtained not only in New England but abroad it appears that one 

 can expect from fully stocked plantations and second growth 

 stands on first quality sites under a fifty-year rotation a maximum 

 yield of one hundred cords and an average of at least sixty-five 

 cords per acre. The study of a large number of fully stocked sec- 

 ond growth stands in New England on first quality sites gave an 

 average yield of nearly seventy cords per acre at fifty years. 



These figures of maximum yield and high value per acre should 

 not be taken as an index of results to be expected from general 

 planting. They do show, however, what has and what can again 

 be attained in the most favorable localities. Experience has 

 shown that the average yield of White pine in fully stocked 

 second growth stands on third quality sites is less than forty cords 

 per acre at the end of fifty years. Plantations of White pine made 

 in southern France on very poor soil in 1873 gave an annual 

 increment of only about one-half cord per acre at the end of 

 thirty-eight years. It costs as much and usually more to estab- 

 lish a forest by planting on poor sites as it does on first quality 

 sites, while the yield may be but one-half or one-third as much. 

 In New England where the value of all forest soils is relatively 

 low a handsome profit may well result from plantations on first 

 quality sites, while a loss would result from planting the same 

 species on third quality sites because of the small diiTerence in 

 initial cost and the great difference in yield. The high yields and 

 values obtained from plantations and second growth stands
