PLATE XIX. 



FIG. 1. IN CLOSELY PLANTED GROVES WHITE PINE FORMS STRAIGHT, CLEAN BOLES. 



FIG 2 EVEN IN BELTS OF A FEW Rows, THE GROWTH OF WHITE PINE is ERECT 

 AND SYMMETRICAL, BUT THE OUTER TREES WILL RETAIN THEIR LOWER BRANCHES 

 FOR MANY YEARS. THE BREAK IN THIS Row SHOWS WHERE A SMALL TORNADO 

 PASSED THROUGH IT.
