THE DESTRUCTIVE EFFECTS OF IVY, 
(he'dera h'elix) 
AS AN IMPEDER OF THE GROWTH OF FOREST TIMBER.

The pleasure I experience in perusing the very interesting commu¬ 
nications I met with in the last number of the Horticultural Regis¬ 
ter, respecting the management and improvement of forest trees, 
would have been much increased, had notice been taken of the effects 
of Ivy (Hedera helix) which encircles and binds in particular the oak :

tent, and observing with much regret the effects of this formidable 
creeper, strongly indicative of the great indifference of those entrust¬ 
ed with the care of such property, in having permitted an enemy of 
the kind to make so great a progress with impunity.

subject are scattered through so many books, that I think you would 
do well to abstract them as they appear, giving the substance in short, 
I say short, because you have one or two communicatoins in late 
numbers which might have been much condensed. Experiments are
