I have never met with the _verb_ in that sense elsewhere,
but overtop is evermore the appropriate term in arboriculture. To quote
examples of that is needless. Of it metaphorically applied, just as in
Shakspeare, take the following example:

"Of those three estates, which swayeth most, that in a manner doth
overtop the rest, and like a foregrown member depriveth the other of
their proportion of growth."--Andrewes' Sermons, vol. v. p. 177., _Lib.
Ang.-Cath. Theol._

Have we not the substantive _trash_ in the sense of shreddings, at p. 542.
book iii. of a _Discourse of Forest Trees_, by John Evelyn? The extract
that contains the word is this:

"Faggots to be every stick of three feet in length, excepting only one
stick of one foot long, to harden and wedge the binding of it; this to
prevent the abuse, too much practised, of filling the middle part and
ends with _trash_ and short sticks, which had been omitted in the
former statute."

Possibly some of the statutes referred to by Evelyn may contain examples of
the verb. In the meantime it will not be impertinent to remark, that what
appears to be nothing more than a dialectic variety of the word, namely
_trouse_, is of every-day use in this county of Hereford for trimmings of
hedges; that it is given by Grose as a verb in use in Warwickshire for
trimming off the superfluous branches; and lastly, that it is employed as a
substantive to signify shreddings by Philemon Holland, who, if I rightly
remember, was many years head master of Coventry Grammar School:

"Prouided alwaies, that they be paued beneath with stone; and for want
thereof, laid with green willow bastons, and for default of them, with
vine cuttings, or such _trousse_, so that they lie halfe a foot
thicke."--The Seuenteenth Booke of Plinie's _Naturall History_, chap.
xi. p. 513.: London, 1634.

_Trash_ no one denies to be a kennel term for hampering a dog, but it does
not presently follow that the word bore no other signification; indeed,
there is no more fruitful mother of confusion than homonomy.

_Clamor_, to curb, restrain (the tongue):

"_Clamor_ your tongues, and not a word more."
_The Winter's Tale_, Act IV. Sc. 4.

Most judiciously does NARES reject Gifford's corruption of this word into
_charm_, nor will the suffrage of the "clever" old commentator one jot
contribute to dispel their
