NEW FORESTS FOR NATION.
Lands in New Hampshire and the South to Be
Acquired—An Important Move.
(Special to The Review.)
WASHINGTON, 1). C... February 15.—The National
Forest Reservation Commission to-day approved
the purchase of 35,370 acres, in addition to the
1,414,208 acres already approved for purchase, for
national forests in the White Mountains of New
England and the Southern Appalachian region.
The lands have been examined and appraised and
sales contracts will be made with the owners by
the Secretary of Agriculture as soon as possible.
The land to be immediately acquired consists
of 11,970 acres in the White Mountain area of
New Hampshire, 9,828 acres in the While Top
area of Virginia, 705 acres in the Shenandoah area
of Virginia, 9,120 acres in the Mount Mitchell area
of North Carolina, and 3,747 acres in the Savan-
nah area of North Carolina. The total amount
of money involved is $233,038, which will be paid
out of the $1,375,000 still available under the
Weeks law.
The owners have already agreed to sell at what
are regarded as very reasonable prices. Practical-
ly all of the land is mountainous, non-agricultural,
and valuable for forests and watershed protection.
Much of it has been culled, but several large tracts
are heavily timbered. The purchase of the White
Mountain acreage will require $03,984.50, at an
average rate of $4.65 an acre; the White Top,
$44,232.50, at $4.50 an acre; the Shenandoah,
$3,736, at $3.80 an acre; the Mount Mitchell,
$99,840, at $10.95 an acre, and the Savannah,
$21,245, at $5.67 an acre. As soon as the pur-
chases are completed by the Secretary of Agricul-
ture the lands will pass into the jurisdiction of the
Forest Service, which will begin their develop-
ment as national forests for the use of the public.

CRUDE RUBBER PRICES WEAKER.
The raising of the English embargo on crude
rubber shipments to this country, under certain
restrictions, has resulted in a general weakening
of prices in this market. The best grade of Para
rubber, up-river fine, was obtainable here Mon-
day at hlV'i cents a pound, spot. This figure was
said to be the lowest quoted in this market since
1882. There was no embargo on the Brazilian
rubbers, but the removal of that on the Eastern
