SIR: have the honor to send here with, by DR..
Gale. the examiner in the extension case Of Chat
fee. nv replies to the charges of Day and others,
and all the papers relating to the case.
As the calumnies of Fuller, Day and others have
been widely circulated by the press, and are now
being circulated in almost every section OF the
Union, in order to render this Office and its admin
istration obnoxious TO public lure, purpose
unless you disapprove, to publish the answers,
with the view of dlsabuslng the public mind and
exposing the covert aud open, and at present com.
bined efforts OF bRttied dishonest agents, defeated
pirates, and hitherto disappointed intriguers -
That these have done their work on the minds OF
MANY have long known, but have not met with
an example equal to the one furnished by you yes
terday In the communication OF Hon. Hugh w hlte.
This gentleman has obviously become alarmed by
visions of frightful official depravity which some
adroit artists in diablerie have shadOwed out be-
fore him, for surely nothing less than alarm could
induce or Justify an enlightened legislator sudden
ly to call upon the Government to apply the star.

for an improvement in the manufacture OF India

together with the Examiners report OF the facts
and the whole testimony in the case. regret
not replying earlier, but l could not, without ar
resting the business OF the Office at the most press
ing season Of its duties
Previous to 1886, the application OF lnula Fuo-
Der to render woven fabrics WATERPROOF was
through q tedious process, and BY means OF al
An establishment in Massachusetts,, known as
the Roxbury Company, expended over $4,000
per annum in the purchase OF this solvent.
Mr.. Chaffee, who was IN the employ OF TINS
company discovered simple mode OF rendering
the rubber sufficiently plastic without sublecttng
il to the action of any solvent whatever-s DIS
coyery that caused complete revolution IN the
trade. Ii produced an article superior to any
thing previously known. Its value may be inier'
red from the fact that il saved a single company,
$4,000 in one year for turpentine alone; besides
q large additional sum consequent on the extra a.
Dor which the use of that solvent required.
A patent was granted 10 Chatfee on the Slst
of August 1886 This he sold 20 the ROXbRry
Company, ut or about that time. The company
subsequently failed, by which he lost greater
part OF the amount he was 10 receive Tor It. Toe
patent went into the hands OF trustees, and en-
tirely beyond the reach Of the inventor who, when
II was about 10 expire sought its extension n or
der that he might resp the reward fox IL, which
he had failed to receive during It's lifetime.
