which in many cases work on the under side
of the branch 50 that the man locking down
cannot see its dangerous condition.
L. A dead leaf with bark falling of indi
Gates that it died at least three months before
and is. therefore, less safe than one with its
bark tightly adhering to it.
5. Look out for limb that shows fungus
growths. Every fungus sends out lot Of
fbres into the main body of the limb whcs
draws out its sap. The interior Of the brana
then loses all strength and becomes like +,
powder.
Is. Branches are more apt to snap on IA
frosty day when they are covered with ang
coating than on a warm summer day.
I. A rainy or drizzy day causes e'
branches of tree to be slippery, and gu's
precautions are then necessary.
For the tree surgeon these bits Of adyicew
contained in leafet on pruning:
Be as sparing and judicious in your prunirg
as possible and do not raise the branches
high as to make the tree look like tee
graph POLE
Do not fail to cover every wound with eosl
tar not allowing it to needlessly run down
the trunk.
Prevent tearing the bark of the tree in n.
moving large limbs by first making an u.
.dercut.
When you shorten a branch leave few
twigs at the end in order to draw the sap
the freshly cut wound and thus enable the
growing layer under the bark TO heal it over.
Starvation has been staring many Of New
York's finest trees in the face for some tine
past. In City Hall Park for example il vas
discovered recently that trees were planted N
nothing but cnders and sand. These valuaN
old specimens have now been placed on nosr'
ishing diet supplied by a new system Of Ter
tilizer.
Frequenters of Park Row and neghborh7ocs
adjoining other city parks are apt to become
very familiar with the sight Of workmen dg'
gng trenches around fine old shade tres
These trenches are four feet in width win al
outer circumference more or less parallel WIN
the branches of the tree. By digging in nch
fertilizer in the trenches new rootlets are en-
couraged. From the main trench radiate spoSes
to the trunk into which are worked fertilizer
and good soil, method much more effective
than mulching.
Two other noteworthy innovations have oeen
introduced into the forests within the limits "
the worlds greatest city. The native Ne'
Yorker will never again be able to snif al u'
odor of burning leaves in the autumn y"
will busy men with rakes remove Natures car
pet of leaves during the fall housecleanns
Leaves are TO be allowed TO remain and decay
enriching the soil. To provide for future ''''
tilizer three leaf mould piles have been e''s'
ished in Central Park. where all leaves :"
stead of being burned, are mixed with sou az
manure in layers, making compost "nS1
within year or two, will form natural We
decomposed fertilizer of great value for VEGA
ened trees.
Forestation methods by which wooded s''''
are TO be allowed to grow under natural eonO'
tons like any other forest are to be !ns'a''.'
City parks are to be planted with Sman W.
costing from 81 to $40 a thousand, SO toa' ~
forests viii be made thicker and mols'u'.
the ground will be conserved. Thus WIN ~
dreds of young trees be constantly proS''sO
take the places of the old.
1t may be fatterng to New Workers 70 Aus
that their principles of tree culture are w.
followed by pupils in China and Japan sn' =
Park Departments experimental work anu ~
coveries are well known throughout the eou"S y.
When the experts on tree health nave ''n '.s.
completed their task the old cry Of Gothsm.
that they must escape the city's heated a,
ments in summer time will be unknown, -,
the contrary, the farm dwellers VIII sesA
city's empowered thoroughfares for coon"s
lief and summer joy.
