PLANTING OF WHITE PINE IN NEW ENGLAND. 



In the midst of this forest is a small grove of red (Norway) pine 

 which was planted at the same time as the white pine. The trees are 

 larger than the white pine, and they seem better adapted to growing 

 close planted, as they do not afford such heavy shade. The trees have 

 pruned themselves well, even better than the white pine. 



The main area of the plantation is level, and extends from the Wolf- 

 boro highway westerly toward Winnepesaukee Lake, in a narrow 

 strip, for over half a mile. The land is quite low, and the soil is a 

 rich, deep, sandy loam, underlaid with gravel. A scattered and irreg- 

 ular mixture of red pine occurs throughout. 



Here is noticed more than elsewhere the great difference between 

 the growth of white pine and that of red pine in close mixture. While 

 the white pine averages less than 4 inches in diameter and 25 feet in 

 height, red pine averages 6 to 7 inches in diameter and 30 to 35 feet in 

 height. Red pine has developed larger branches than white pine, and 

 hence has a greater crown surface. The former seems also better able 

 to heal over wounds than the latter. Dead branches of red pine decay 

 and fall, while those of the white pine adhere tenaciously to the trees. 



One-half mile southeast of the post-office of Moultonboro is the 

 youngest portion of the forest, planted in 1874. The land had been 

 cropped and was in good condition for planting. This portion has 

 succeeded better than any of the others, mainly because thinning was 

 practiced when needed, thus giving opportunity for the development 

 of a large crown. The first thinning was made when the trees were 

 21 years old. The crowns are in excellent health and the trees tall 

 and straight, having made a height growth of from 40 to 55 feet. 



MEASUREMENTS. 



In Mr. Adams's planted forest over 40,000 white pine were meas- 

 ured. Measurements of red pine were also taken to find its growth in 

 comparison with white pine. The following is the rate of growth for 

 the whole plantation:

The much better showing of the 27-year-planted trees in comparison 

 with the 30-year-planted is due partly to better soil conditions and 

 partly to the beneficial effect of thinning.
