BOXWOOD SUBSTITUTES.

First among the substitutes that have been proposed to replace boxwood

may be mentioned an invention of Mr. Edward Badoureau, referred to in

the _Gardeners' Chronicle_, March 23, 1878, p. 374, under the title of

artificial boxwood. It is stated to consist of some soft wood which has

been subject to heavy pressure. It is stated that some English engravers

have given their opinion on this prepared wood as follows:

It has not the power of resistance of boxwood, so that it would be

imposible to make use of it, except in the shape of an electro obtained

from it, as it is too soft to sustain the pressure of a machine, and

would be easily worn out. In reply to these opinions, Mr. Badoureau

wrote: "My wood resists the wear and tear of the press as well as

boxwood, and I can show engravings of English and French artists which

have been obtained direct from the wood, and are as perfect as they are

possible to be; several of them have been drawn by Mr. Gustave Dore."

Mr. Badoureau further says that "while as an engraver he has so high an

opinion of the qualities of compressed wood as a substitute for boxwood,

as the inventor of the new process he considered that it possesses

numerous advantages both for artistic and industrial purposes." In

short, he says, "My wood is to other wood what steel is to iron."

The following woods are those which have, from time to time, been

proposed or experimented upon as substitutes for boxwood, for engraving

purposes. They are arranged according to their scientific classification

in the natural orders to which they belong:

_Natural Order Pittosporeæ_.

1. _Pittosporum undulatum_. Vent.--A tree growing in favorable

situations to a height of forty or even sixty feet, and is a native of

New South Wales and Victoria. It furnishes a light, even grained wood,

which attracted some attention at the International Exhibition in 1862;

blocks were prepared from it, and submitted to Prof. De la Motte, of

King's College, who reported as follows:

"I consider this wood well adapted to certain kinds of wood engraving.

It is not equal to Turkey box, but it is superior to that generally used

for posters, and I have no doubt that it would answer for the rollers

of mangles and wringing machines." Mr. W.G. Smith, in a report in the

_Gardeners' Chronicle_ for July 26, 1873, p. 1017, on some foreign woods

which I submitted to him for trial, says that the wood of _Pittosporum

undulatum_ is suitable only for bold outlines; compared with box, it is

soft and tough, and requires more force to cut than box. The toughness

of the wood causes the tools to drag back, so that great care is

required in cutting to prevent the lines clipping. The average diameter

of the wood is from 18 to 30 inches.

2. _Pittosporum bicolor_, Hook.--A closely allied species, sometimes

forty feet high, native of New South Wales and Tasmania. This wood is

stated to be decidedly superior to the last named.

3. _Bursaria spinosa_, Cav.--A tree about forty feet high, native of

North, South, and West Australia, Queensland, New South Wales, Victoria,

and Tasmania, in which island it is known as boxwood. It has been

reported upon as being equal to common or inferior box, and with

further trials might be found suitable for common subjects; it has the

disadvantage, however, of blunting the edges and points of the tools.

_Natural Order Meliaceæ_.

4. _Swietenia mahagoni_, L. (mahogany).--A large timber tree of

Honduras, Cuba, Central America, and Mexico. It is one of the most

valuable of furniture woods, but for engraving purposes it is but of

little value, nevertheless it has been used for large, coarse subjects.

Spanish mahogany is the kind which has been so used.

_Natural Order Ilicineæ_.

_Ilex opaca_, L. (North American holly).--It is a widely diffused tree,

the wood of which is said to closely resemble English holly, being white

in color, and hard, with a fine grain, so that it is used for a

great number of purposes by turners, engineers, cabinet makers, and

philosophical instrument makers. For engraving purposes it is not equal

to the dog-wood of America (_Cornus florida_); it yields, however, more

readily to the graver's tools.

_Natural Order Celastrineæ_.

6. _Elæodendron australe_, Vent.--A tree twenty to twenty-five feet

high, native of Queensland and New South Wales. The wood is used in the

colony for turning and cabinet work, and Mr. W.G. Smith reports that for

engraving purposes it seems suitable only for rough work, as diagrams,

posters, etc.

7. _Euonymus sieboldianus_, Blume.--A Chinese tree, where the wood,

which is known as pai'cha, is used for carving and engraving. Attention

was first drawn to this wood by Mr. Jean von Volxem, in the _Gardeners'

Chronicle_ for April 20, 1878. In the Kew Report for 1878, p. 41, the

following extract of a letter from Mr. W.M. Cooper, Her Majesty's Consul

at Ningpo, is given: "The wood in universal use for book blocks, wood

engravings, seals, etc., is that of the pear tree, of which large

quantities are grown in Shantung, and Shan-se, especially. Pai'cha is

sometimes used as an indifferent substitute. Pai'cha is a very fine

white wood of fine fiber, without apparent grains, and cuts easily; is

well suited for carved frames, cabinets, caskets, etc., for which large

quantities are manufactured here for export. The tree itself resembles

somewhat the _Stillingia_, but has a rougher bark, larger and thinner

leaves, which are serrated at the edge, more delicate twigs, and is

deciduous." In 1879, a block of this wood was received at the Kew

Museum, from Mr. Cooper, a specimen of which was submitted to Mr. Robson

J. Scott, of Whitefriars Street, to whom I am much indebted for reports

on various occasions, and upon this wood Mr. Scott reported as follows:

"The most striking quality I have observed in this wood is its capacity

for retaining water, and the facility with which it surrenders it. This

section (one prepared and sent to the Kew Museum), which represents

one-tenth of the original piece, weighed 3 lb. 4½ ounces. At the end of

twenty one days it had lost 1 lb. 6¾ ounces in an unheated chamber. At

the end of another fourteen days, in a much elevated temperature, it

only lost ¼ ounce. In its present state of reduced bulk its weight is 1

lb. 10 ounces. It is not at all likely to supersede box, but it may be

fit for coarser work than that for which box is necessary." Later on,

namely in the Kew Report for 1880, p. 51, Mr. R.D. Keene, an engraver,

to whom Mr. Scott submitted specimens of the wood for trial, writes: "I

like the wood very much, and prefer it to box in some instances; it is

freer to work, and consequently quicker, and its being uniform in color

and quality is a great advantage; we often have great difficulty in

box in having to work from a hard piece into a soft. I think it a very

useful wood, especially for solid bold work. I question if you could get

so extreme a fine black line as on box, but am sure there would be a

large demand for it at a moderate price." Referring to this letter, Mr.

Scott remarks that the writer does not intend it to be understood that

pai'cha is qualified to supersede box, but for inferior subjects for

which coarse brittle box is used. Mr. Scott further says that of the

woods he has tried he prefers pear and hawthorn to pai'cha.

_Natural Order Sapindaceæ_.

8. _Acer saccharinum_, L. (sugar or bird's eye maple).--A North American

tree, forming extensive forests in Canada, New Brunswick, and Nova

Scotia. The wood is well known as a cabinet or furniture wood. It has

been tried for engraving, but it does not seem to have attracted much

notice. Mr. Scott says it is sufficiently good, so far as the grain is

concerned. From this it would seem not to promise favorably.

_Natural Order Leguminoseæ. Sub-order Papilionaceæ_.

9. _Brya ebenus_, [Delta]. DC.--A small tree of Jamaica, where the wood

is known as green ebony, and is used for making various small articles.

It is imported into this country under the name of cocus wood, and

is used with us for making flutes and other wind instruments. Mr.

Worthington Smith considers that the wood equals bad box for engraving

purposes.

_Natural Order Rosaceæ_.

10. _Pyrus communis_, L. (common pear).--A tree averaging from 20 to 40

feet high. Found in a wild state, and very extensively cultivated as a

fruit tree. The wood is of a light brown color, and somewhat resembles

limewood in grain. It is, however, harder and tougher. It is considered

a good wood for carving, because it can be cut with or across the grain

with equal facility. It stands well when well seasoned, and is used for

engraved blocks for calico printers, paper stainers, and for various

other purposes. Pear-wood has been tried for engraving purposes, but

with no great success. Mr. Scott's opinion of its relative value is

referred to under pai'cha wood _(Euonymus sieboldianus)_.

11. _Amelanchier canadensis_. L. (shade tree or service tree of

America).--A shrub or small tree found throughout Canada, Newfoundland,

and Virginia. Of this wood, Porcher says, in his "Resources of the

Southern Fields and Forests": "Upon examining with a sharp instrument

the specimens of various southern woods deposited in the museum of the

Elliott Society, ... I was struck with the singular weight, density, and

fineness of this wood. I think I can confidently recommend it as one of

the best to be experimented upon by the wood engraver."

12. _Cratoegus oxyacantha_, L. (hawthorn).--A well-known shrub or small

tree in forests and hedges in this country. The wood is very dense and

close grained. Of this wood, Mr. Scott reports that it is by far the

best wood after box that he has had the opportunity of testing.

_Natural Order Myrtaceæ_.

13. _Eugenia procera_, Poir.--A tree 20 to 30 feet high, native of

Jamaica, Antigua, Martinique, and Santa Cruz. A badly seasoned sample

of this wood was submitted to Mr. R.H. Keene, who reported that "it is

suited for bold, solid newspaper work."

_Natural Order Cornaceæ_.

14. _Cornus florida_, L. (North American dogwood).--A deciduous tree,

about 30 feet high, common in the woods in various parts of North

America. The wood is hard, heavy, and very fine grained. It is used in

America for making the handles of light tools, as mallets, plane stocks,

harrow teeth, cogwheels, etc. It has also been used in America for

engraving.

In a letter from Prof. Sargent, Director of the Arnold Arboretum,

Brookline, Massachusetts, quoted in the Kew Report for 1882, p. 35, he

says: "I have been now, for a long time, examining our native woods

in the hope of finding something to take the place of boxwood for

engraving, but so far I am sorry to say with no very brilliant success.

The best work here is entirely done from boxwood, and some _Cornus

florida_ is used for less expensive engraving. This wood answers fairly

well for coarse work, but it is a difficult wood to manage, splitting,

or rather 'checking,' very badly in drying." This, however, he states in

a later letter, "can be overcome by sawing the logs through the center

as soon as cut. It can be obtained in large quantities." Mr. R.H. Keene,

the engraver before referred to, reports that the wood is very rough,

and suitable for bold work.

_Natural Order Ericaceæ_.

15. _Rhododendron maximum_, L. (mountain laurel of North America).--Of

this wood it is stated in Porcher's "Resources of the Southern Fields

and Forests," p. 419, that upon the authority of a well-known engraver

at Nashville, Tennessee, the wood is equaled only by the best boxwood.

This species of _Rhododendron_ "abounds on every mountain from Mason and

Dixon's line to North Georgia that has a rocky branch." Specimens of

this wood submitted to Mr. Scott were so badly selected and seasoned

that it was almost impossible to give it a trial. In consideration of

its hardness and apparent good qualities, further experiments should be

made with it.

16. _Rhododendron californicum_.--Likewise a North American species, the

wood of which is similar to the last named. Specimens were sent to Kew

by Professor Sargent for report in 1882, but were so badly seasoned that

no satisfactory opinion could be obtained regarding it.

17. _Kalmia latifolia_, L. (calico bush or ivy bush of North

America).--The wood is hard and dense, and is much used in America for

mechanical purposes. It has been recommended as a substitute for boxwood

for engraving, and trials should, therefore, be made with it.

_Natural Order Epacrideæ_.

18. _Monotoca elliptica_, R. Br.--A tall shrub or tree 20 or 30 feet

high, native of Queensland, New South Wales, Victoria, and Tasmania.

The wood has been experimented upon in this country, and though to all

appearances it is an excellent wood, yet Mr. Worthington Smith reported

upon it as having a bad surface, and readily breaking away so that the

cuts require much retouching after engraving.

_Natural Order Ebenaceæ_.

19. _Diospyros texana_.--A North American tree, of the wood of which

Professor Sargent speaks favorably. "It is, however," he says, "in

Texas, at least, rather small, scarcely six inches in diameter, and not

very common. In northern Mexico it is said to grow much larger, and

could probably be obtained with some trouble in sufficient quantities

to become an article of commerce." Of this wood Mr. Scott says: "It is

sufficiently good as regards the grain, but the specimen sent for

trial was much too small for practical purposes." Mr. R.H. Keene, the

engraver, says it "is nearly equal to the best box."

20. _Diospyros virginiana_, L. (the persimmon of America).--A good-sized

tree, widely diffused, and common in some districts. The wood is of a

very dark color, hard, and of a fairly close grain. It has been used in

America for engraving, but so far as I am aware has not been tried

in this country. It has, however, been lately introduced for making

shuttles.

21. _Dyospyros ebenum_, Koenig (ebony).--A wood so well known as to

need no description. It has been tried for engraving by Mr. Worthington

Smith, who considers it nearly as good as box.

_Natural Order Apocyneæ_.

22. _Hunteria zeylanica_, Gard.--A small tree, common in the warmer

parts of Ceylon. This is a very hard and compact wood, and is used for

engraving purposes in Ceylon, where it is said, by residents, to come

nearer to box than any other wood known. On this wood Mr. Worthington

Smith gave a very favorable opinion, but it is doubtful whether it would

ever be brought from Ceylon in sufficient quantities to meet a demand.

_Natural Order Bignoniaceæ_.

23. _Tecoma pentaphylla_, Dl.--A moderate-sized tree, native of the West

Indies and Brazil. The wood is compact, very fine, and even grained, and

much resembles box in general appearance. Blocks for engraving have been

prepared from it by Mr. R.J. Scott, who reported upon it as follows: "It

is the only likely successor to box that I have yet seen, but it is not

embraced as a deliverer should be, but its time may not be far off."

_Natural Order Corylaceæ_.

24. _Carpinus betulus_, L. (hornbeam).--A tree from 20 to 70 feet high,

with a trunk sometimes 10 feet in girth, indigenous in the southern

counties of England. The wood is very tough, heavy, and close grained.

It is largely used in France for handles for agricultural and mining

implements, and of late years has been much used in this country for

lasts. The wood of large growth is apt to became shaky, and it is

consequently not used as a building wood. It is said to have been used

as a substitute for box in engraving, but with what success does not

appear.

25. _Ostrya virginica_, Willd (ironwood, or American hornbeam).--A

moderate-sized tree, widely spread over North America. The wood is

light-colored, and extremely hard and heavy; hence the name of ironwood.

It is used in America by turners, as well as for mill cogs, etc., and

has been suggested as a substitute for boxwood for engraving, though no

actual trials, so far as I am aware, have been made with it.

Besides the foregoing list of woods, there are others that have been

occasionally used for posters and the coarser kinds of engraving, such,

for instance, as lime, sycamore, yew, beech, and even pine; and in

America, _Vaccinium arboreum_ and _Azalea nudiflora_. Of these, however,

but little is known as to their value.

It will be noticed that in those woods that have passed through the

engraver's hands, some which promised best, so far as their texture

or grain is concerned, have been tried upon very imperfect or badly

seasoned samples.

The subject is one of so much importance, as was pointed out at the

commencement of this paper, that a thoroughly organized series of

experiments should be undertaken upon carefully seasoned and properly

prepared woods, not only of those mentioned in the preceding list, but

also of any others that may suggest themselves, as being suitable, It

must, moreover, always be borne in mind that the questions of price,

and the considerations of supply and demand, must, to a great extent,

regulate the adaptation of any particular wood.

With regard to those woods referred to as being tried by Mr. Worthington

Smith, he remarks in his report that any of them would be useful for

some classes of work, if they could be imported, prepared, and sold for

a farthing, or less than a halfpenny, per square inch.

Specimens of all the woods here enumerated are contained in the Kew

Museum.
