process has been discovered according the following
extract from The London Mining Journal of July 22d by which
soft and useless stone becomes hard and valuable. This
almost much believe, but have learned think
ce before express doubts in relation almost any thing
therefore will not doubt these statements, yet will not
promise to believe them without evidence The writer
in the Journal says in relation to Hutchsons Indurattd
Stone: :"
eve have much pleasure in observing that this valuable
ea is quietly, but surely forcing is way public estimation
The principal materials present operated upon the beau
tfu eestone at Caen, in Normandy, end worthless sand
stone which crumbes between the fingers Caveey Quar-
~, Tonbrdge Kent but which, have before stated in
notices the subject rendered hard and durable
as granite The pNenIee, TO whose ongprcservng efforts
must be ascrbed The perfection TO which the processes
brought STILL in tho most handsome manner, publicly de-
cnes the doe The original nvsnon II first dis
covered by NJ Charles lie Goux, Of Bayeur Normandy,
and Of whom M Hutchison purchased the breuet dRre-
o which had been taken for France and has taken
out patents for this and other countries We think the merits
o The substance ppluced generally becoming known
TO the public and time continues TO give additional proofs
OF its economy and the perfect nJsrucubly Of The erals,
and probably sill further improvements may be made 10
cooring during the nduretng process rendering APP
pcabe than present the finer works Of art il is likely
become Of the valuable discoveries Of this exrao
nay inventive age. As we have often fully described The
processes and their effects it would he superous for
this occasion repeat them To show, however, that
following from the SUSSEX Express:
"'Having heard much of Mr. Hucbsons method Of ndu-
rating sone induced TO visit his works al Jack oo
Spring Thursday last. We had BEEN prepared TO expect
TO find that the stone which had been subject the process
nduation had been completely reianophsed but must
confess not prepared to the soft ia K
Woods, which in its natural state crumbes to powder with
the slightest pressure between the thumb and finger rendered
hard granite marble Several pecfs that shoa
close Imlons Of various kinds Of the mos. bcsut
fully grained and black bic and by this process is
rendered absolutely impershabc from atmos hec action aud
capable OF receiving the highest polish can without the
slightest hesitation, accord Mr. Huchsan the merit Of max
ing one OF the most extraordinary discoveries Of the present
age The purposes to which this patent be applied
innumersbe The soest stone, chalk wood, paper, &c.
be rendered bard metal that the rub
hs be turned to the valuable purposes aud, u
crown all the cost much lower than any other that has nth
oro been introduced f purposes which be applied
Of course IN the Of newspaper paragraph il would bc
impossible 10 enumera,e 1.-THE of the benefits this discovery
likely to confer society bot from the information
gathered while inspecting the works consider highly de-
serving the attention Of engineers architects scurs build
ers, and even Of surveyors OF highwys.'"
