creased demand for pine lumber brings in the portable saw- 
mill, one of tbe chief contributing causes to the diminution 
of hawks, owls, grouse, and all birds which breed or seek 
cover in a heavy pine growth. Mr. Prentiss says : “ A man 
who is a good shot can now, with a dog, follow and kill 
nearly every bird he flushes; while formerly at least 60 
per cent of the birds flushed in a day’s hunting would take 
to the heavy growth of pine and escape, — at least for that 
day.” Everywhere I go in eastern Massachusetts the white 
pine is being cut off. Thousands of acres were cut in the 
State in 1903. The demand is everywhere increasing. The 
great storm of November, 1898, uprooted acres of large pine 
timber in Plymouth County. Then came the coal strike of 
1902, which caused the cutting of many acres of wood of all 
kinds. This, in addition to the regular demand for pine 
timber, has caused the destruction, says Mr. A. C. Dyke, 
of many of the favorite nesting trees of the larger hawks. 
Cutting pine timber drives out birds which, like the black- 
throated green warbler, nest there. Where these pines are 
succeeded by hard-wood trees, other birds will take the places 
of those driven out ; 1 but where, as in the suburbs of cities, 
these trees are cut and the ground cleared of even shrubbery, 
the sparrows, warblers, towhees and thrushes are driven out, 
as well as the wood birds. Lawns, golf links, country club 
grounds and grassy parks are unsuitable for the birds of the 
tangle, and they will not live in such places. The work of 
destroying the gypsy moth is now necessitating much tree 
cutting and cleaning up of shrubbery and tangles. This is 
bad for the birds, and must result in reducing the numbers 
of some species in the region infested by the moth. 
Mr. C. J. Maynard, in his recent work, “ The Warblers 
of New England,” 2 speaks particularly of the warblers hav- 
ing been driven from parks, pleasure grounds and the vicinity 
of cities by the destruction of the shrubbery. While this may 
not diminish the number of birds in the State, it tends to 
drive the birds away from many places where they might be 
retained under a different policy. 
1 Prof. J. W. Votey of Burlington, Vt., believes that the growth which follows the 
cutting off of the spruce furnishes better nesting areas for the birds than those they 
formerly had. 2 Completed Jan. 1, 1905.
