CRESTED TITMOUSE. 145 



The species of pine, on a twig of which you see a pair of these birds, is the 

 white pine {Pinus Strobus), a tree of great beauty, of which individuals 

 have been observed of the enormous height of ISO feet, with a diameter at 

 the base of from six to eight feet. The trunk is branchless for two-thirds of 

 its height, and affords the most valuable wood perhaps of any tree in the 

 United States.
