piece OF bark nVe inches long ana tnret
inches high was removed from the outer
layer of wood, and piece of sheet-iror
driven into the bark below to catch the
sap, which flowed very profusely but
stopped very early. The tree, from the
heart OF which the sap was taken as
above described, flowed eleven days
longer'than the similar one from which
only q piece of bark was removed, but
the latter afforded twelve pounds more
of the fluid.
In the case of a tree tapped on the
north and south sides at the same level
it was found that the north spout yield
ed daily about twice as much sap as the
south spout. and continued to flow
nearly two weeks longer. The tree
was tapped March 19, and yielded sew.
enty pounes of sap, containing two and
a half pounds of sugar.
In order to discover whether the
sweetness of the sap was the same in all
parts of the tree, spout was inserted
into healthy maple, which had never
been tapp ID, at the usual height, and
fifty feet above this another spout was
set into the trunk where it was about
five inches in diameter. In seven hours
the lower spout had bled six pounds OF
sap lile liino, TWO ounces ana the up
per spout, not urop. similar eXperl-
mcnts on different trees showed that
the sap flowed most freely within
twelve feet of the earth, and that the
flow diminished rapidly above this
height.
This fact corresponds with the curious
