II. Facrs GATHERED FROM EIGHT YEARS OF PERSONAL IN- 
SPECTION AS TO THE ALLEGED DESTRUCTION OF THE ADIRON- 
DACK FORESTS. 
In this paper Prof. LEEDs urged some action of the Academy, 
in co-operation with the present public movement, to protect and 
preserve the forests of the Adirondack region. 
DISCUSSION. 
Prof. O. P. HUBBARD remarked that nearly fifty years ago a feeder 
from the Black River was surveyed and constructed to the sources of 
the Mohawk to éring water to the middle section of the Erie Canal, 
the summit level between the Lakes and the Hudson River; and subse- 
quently a caval even was built from Booneville to Rome, in part to 
bring agreater supply. When the hemlock forests back of Newburg, 
where immense tanneries once existed, were exhausted, there was a 
transfer to the southern border of the Adirondacks north of the Mo- 
hawk, where a similar destruction has been going on. This region, 
though very favorable for grazing, is not attractive on account of the 
climate for general agriculture; and great proprietors, like Brown, of 
Providence, and Gerrit Smith, of New York, never succeeded in at- 
tracting settlers, though land was offered at a few cents an acre. 
It should be considered, however, that forests can be renewed, if 
protected in time. In thirty to forty years a tract may be reforested 
with the soft and hard woods, as the experience of cultivators in for- 
eign countries and in our land has shown—one of the former, in the last 
century, having planted fifty millions of forest trees on his estate in Scot- 
land, besides what he has sown and wot transplanted, which cannot be 
numbered. (‘‘ Diary and Letters of Gov. Thomas Hutchinson,” 1884, 
p- 343-) Ifallsmalllandholders, farmers, and citizens, who have only a 
garden, would encourage their boys to plant the seeds of apples, pears, 
and fruits in general, also the walnuts, chestnuts, beechnuts, butter- 
nuts, and English walnuts, maples, elms, oaks, pines, hemlock, 
larches—there might be, if properly transplanted, hundreds of millions 
of valuable trees added to our stock in forty years. 
The encouragement of this industry by means of premiums given 
by the State is a thousandfold more important than all ever paid by 
our agricultural societies for large vegetables and small extraordinary 
crops, and would add vastly to the wealth of the State.
