The daily union. [volume] (Washington [D.C.]) 1845-1857, 1847-08-25

Our attention has been called to the following article
from the Baltimore American. We have made inquiry at
the General Post Office and understand that the description
substantially correct and that the opinion of the most
perenced persons in the Office is very favorable to the
canvass bag and that very superior article is now be-
ing manufactured, which, it is supposed, may eventually
supersede the use of leather for mai-bags. 1t is
said to be certainly more durable, and more mpervious
to water We shall rejoice at its success 1t was but
two weeks ago that newspaper mail from the far
west came to drenched in rain, and dscooed in
every way, to prevent dcciphering many of the
papers.
IMPROVED MlL-BAGs.-We examined few days since,
the establishment Of Messrs Gambrli, Carroll and Co,
which those gentlemen have a patent. The material Of
which the bag is constructed is thick cotton bagging,
vious to waef We were shown one bag manufactured
by gentlemen in $780, which had been five years in
present single stain from the leakage OF water into it, and
looked almost clean and white specimens
"Thc United States letter mail has heretofore, and is
now, great extent, carried in leathern bags which,
while they expensive, by means imperviou
water; and convinced have the Post Office Depart
neni become OF the superior merit OF the bag ia
utng them for the leathem bag as the latter becomes
useless from wear These gentlemen are now ming
large government contract.
But in addition the improved material of which
less expensive than leather is twice durabe-they have
also effected improvement in the manner OF fastening
the bags, which renders them peculiarly adapted to the
carrying oil the newspaper mall This mail Is now carried
bags made of thin cotton baggng totally incapable OF
turning OIL waer-Ior every mail that arrives from the
south west during the rainy season Is generally well
oakcd-and secured at the mouth merely by string
like bag OF meal, to which is attached wooden, and
very often nothing but paper label bearing the OF
the place which the bag is destined Let this label be
lost case, and the bag is liable to be
misplaced mssent and is often detained from its
destination for n day This, verify believe, is
the than one-half the mistakes which
the souls and try the patience OF post Office clerks
newspaper publishers, and through them the reading
public generally.
'ut such accident happen any of the bags Of
Mcssrs. Gambril Carroll, " Co.'s make AT the mouth of
these bags eahcrn flaps, short and the other
long To the shorter there Is attached number oil
buckle frames, which pass through corresponding
lolcs the long flap Through these buckle frames Is
broad lea hern passing the front OF the
bag and fastening behind with any species OF lock which
may be thought convenient This strap is attached TO the
bag that either side of may be turned out; that on
bag OF this kind, which might be used in carrying the ma

that of Phlade phia the other and the only change
cessary passing the bag from city another would
be the reversing OF the straps whilst thus labelled would
be i'm possible for them 10 be misplaced mssent except
through the grossest Negligence.
Tnc first of providing these bags for both the letter
cost of the Icathern and bags, whilst in du
rabty and every other necessary requirement. they
lar Their substitution for those at present in
use would we think, be desirable step, and one which
we unde and present engages the serious attention OF
the Postmaster General"
