BOXWOOD AND ITS SUBSTITUTES.
[Footnote: Prize essay written for the International Forestry
Exhibition, Edinburgh.]
By JOHN R. JACKSON. A.L.S., Curator of the Museums, Royal Gardens, Ken.
The importance of the discovery of a hard, compact, and even grained
wood, having all the characteristics of boxwood, and for which it would
form an efficient substitute, cannot be overestimated; and if such
a discovery should be one of the results of the present Forestry
Exhibition, one of its aims will have been fulfilled.
For several years past the gradual diminution in the supplies of
boxwood, and the deterioration in its quality, have occupied the
attention of hardwood merchants, of engravers, and of scientific men.
Of merchants, because of the difficulties in obtaining supplies to meet
the ever increasing demand; of engravers, because of the higher prices
asked for the wood, and the difficulty of securing wood of good size and
firm texture, so that the artistic excellence of the engraving might be
maintained; and of the man of science, who was specially interested
in the preservation of the indigenous boxwood forests, and in the
utilization of other woods, natives, it might be, of far distant
countries, whose adaptation would open not only a new source of revenue,
but would also be the means of relieving the strain upon existing
boxwood forests.
