The material known as Woodlte, de-
vised by Mrs. Wood, clever English
woman, promises to become q very useful
substance. It's chief ingredient is csout-
chouc. During the past few months it has
given good results for variety of pur-
poses, and is now declared to be especial
ly adspted to many other uses.
According to Sir Edward Reed, M P,
1t has been produced in divers
forms, such as fine sheets and
ribbons for waterproof articles, dense
blocks for resisting the blows OF shot or
shell, and particularly satisfactory rings
for engine packing. One process con-
verts it into an elastic, sponge-like sub
stance; and another, in which it is mixed
with whalebone cuttings, gives it q
rough or FRACTIONAL quality for mats.
Some curious naval applications
have been worked out. 1t is made |
into armor plates, which on being pene-
trated by shot close 60 tightly that no |
weteris admitted, and it Is also formed |
into light and convenient cylinders for |
carrying compressed cir to drive life |
boats, torpedo-boats and scout-boats, |
while ii is suitable for making floating or
partly floating cables for protection |
against torpedo attacks, etc.
"The recently invented process" says
Iron, "by which wood is made to take on
some Of the special characteristics OF met. |
al, has been turned to practical account |
in Germany. By this process the surface |
becomes so hard and smooth as to be sus-
ceptible Of high polish, and may be |
treated with burnisher of either glass |
or porcelain; the appearance Of the |
wood being then In every re-
spect that of polished metal, having, |
in fact, the semblance of polished mir. |
ror, but with this peculiar and advan-
tageous difference namely, that, unlike |
metal, it is unaffected by moisture. To
reach this result the wood is STEPPED in q |
bath Of caustic alkali fcr two or three |
days together, according to its degree Of
at Temperature OF
between 164o and 2970 Fahrenheit.
1t is then placed in second bath of ny
drosulphate Of calcium, to which con-
centrated solution of sulphur is added
after some twenty-four or twenty six
hours. The third bath is one of acetate
Of lesd, at temperature Of from go to
1907 Fahrenheit, and in this lat
ter the wood g allowed to re-
main from thirty to fifty hours.
After being subjected to thorough dry.
Ing it is In condition for being polished
with lead, tin or zinc, as may be desired,
finishing the process with burnisher,
when the wood apparently becomes
piece Of shining polished metaa."
