WE have pleasure in calling the attention of
SI-lIP OWNERS to Messrs. BROWELL and Co.'s
discovery for the prevention of MILDEW in CANVAS, at a
time.when the immense property vested in Shipping is suffering
severely from the ruinous diminution of freightage. Their
'process prevents mildew in flaxen and hempen Canvas of
every description ; .not only, in those kinds of CanVas which are
whitened by bleaching, bitt the browner kinds are also secured
by this process from. mildew, whether in use or laid up in store.
An opportunity is thus given of using with safety these kinds of
bream Canvas, which, when made of good materials and evenly
woven, are stronger than 'the Coker Canvas, and have been ex
eluded from use on board the superior class of Ships solely
from their liability to mildew. Messrs. AIKIN, BABING-
TON and MARCET,' Certify in regard to the just principles
of the preparations ; while experiments triade in the -Royal,
Navy for several years, conducted by the orders of the Navy
Board under the- care of their own officers on the' caw of
Africa, America and Newfoundland, amply prove the efficacy
of Messrs. BRO LL'S Discovery.
- The Pro'cess is affigted for Five Shillings per Bolt, and re-
turned the same lengthand breadth as received. T ht-:benefi of th is
invention ,has been proved, by order of the Navy Board, in se-
veral of his Majesty's Ships of War, in Europe, the Coast of
Africa, America, and Newfoundland, as well as by highly re-
spectable Ship'Owners, which may be seen in the iirinted copies
of Testimonials 'to be had -at BROWELL and Co.'s•Ware-'
house. No. 23, ALDERMANBURV, where various kinds of
prepared Canvas may be seen. • -
N-B. This discovery will be fintrul of great benefit if applied
to Bolts of Canvas taken out as Sea Stores or for Exportation ;
and may always be known by a CroWn and the letter B marked
red in various places.

TIONOURABLE Sins—Since I reported to you the. state of
the Ranger transport's tore-sail, on the 17th inst., part of which
is made, of Messrs. Browell and Co.'s canvas to prevent mildew,
Mr. Lee, themaster, has applied to have nine inches taken off
the head of the said sail, to make it stand better, and on cutting
this piece off, we found fourtetn cloths of the common canvas to
be so rotten as to be obliged to shift them from the head to the
reef, while the prepared canvas appears to be good and service-
able.—l am, honourable'Sirs,
Your most obedient Servant,

Extract of a Letter from J. Fit :molly.' Esq. Acting Captain
on board his Majesty's ship Crocodile.
Finchley, Nov. 12, 1811.
received your letter requesting my opinion on the
process made use of by you for preventing mildew in sail cloth,
which was tried last year on board his Majesty's Ship Crocodile,
on the Coast of Africa. As.l had chiefly the command of the
Crocodile during her continuance on that coast; I made parti-
cular observations on those :sails, which had in them canvas
above alluded to, and therefore I can speak decidedly on the re-
'suit which took place. I have, then, not the smallest hesitation
in saying, that your canvas, during a most severe trial in the
rainy season, succeeded admirably, I did not observe any
mildew to have materially affected it ; as for the King's, that is
quite out of the question, for it soon got so rotten as to be of no
*Jae whatever. From
.what I have seen of your
,canyas, I am of
opinion, that were it made use of in the Navy,
,it would prove
a great saving to Government; and therefore, knowing it to
possess' uch merits, I cannot but sincerely wish that its -adop-
tion may take place.,--I am, Sir, your's,' &c. &c.

GENTLEMEN—Referring to. your letter of the 18th of Dec.
1811, relative to Messrs. Browell and Co.'s prepared canvas to
prevent mildew, we the Undersigned, Captain, First Lieute-
nant, and Master, are of opinion, after a due course of trial,
that the prepared canvas cloths in the mainsail and foretopsail
wear very well, and keep. quite free of mildew.
We are, gentlemen,
Your inns; obedient humble Servants,

• "Portsmouth harbour, Dec. 17, 1803.
GEN EmE take :the liberty of transmitting herewith
a piece of canvas,. N. 2, prepared by Messrs. Browell and Co.
of London, on the principle of resisting the destructive effects
occasioned by mildew. And in order to ascertain whether or
not it possessed this desirable property, I thought proper to wet
it well with rain-water, and immediately after bent and furled
it to a small yard,
.fixing it some distance • above the poop, in a
situation perfectly exposed to all weather during November and
part of December. The result of this severe trial is highly fa-
vourable to it, for on opening the said canvas, after being furled
six weeks in manner above described, at a season of the year
too, the most trying to canvas, there appeared not the smallest
vestige of mildew. The outside skin, you will please to ob-
serve, is in a slightdegree tinged with black, proceeding en-
tirely from smoke and dust. It possessing such essential good
qualities, induces me- to send it nor your inspection, presuming
it would be highly advantageous to his Majesty's Service, if
adopted in the Navy.'
. I have the honour to be, Gentlemen,
Your most obedient, humble servant,
JAMES ROSE,
To the Principal Officers Lieut. and Commander.
and Commissioners of his Majesty' Navy.

These are to certify to those whom it may concern, that a
piece of canvas .that had undergone a process by Air. James
Browell,' was wet with fresh water, and rolled up, and tied to
the cross jack yard anin of , his Majesty's ship Roebuck, in' oc-
tob er , 1809 ; at the same time apiece of Ring's canvas was wet
and tied to the cress jack yard opposite, in like manner, where
they remained till August,l3lo.- When taken down, the canvas,
that had undergone a process by Mr. James Browell was per-
fectly sound, and free from mildew, and fit for any purpose ;
at the same time, the King's canvas was rotten, completely
mildewed, and'fit for no use except paper stuff.

Srh--,As I Understand you are interested in the success of a
particular process, by which the ill 'effects of weather and mil-
dew on canvas are prevented, I no myself the pleasure of stat-
ing to you. my opinion of its utility from its effects on a tent
which 1 purchased froin Messrs. browelY and, Co. This tent
was sent on. board tha Maiiner, Captain Weatherhead, in
which I embarked in January 109. After a long voyage to
the Red Sea, I found it, on comparison with three others which
I received from the Ordnance Stores at. Woolwich, in much
better condition, though they had bean kept in the same place.
I used it on some of the islands of the Red Sea, in the early
part of the year 1810, during some heavy rains, anti .on my
journey :for some months into the interior of Abyssinia.'
Though it be probable that no methcfl of preparing canvas can
ever enable it entirely to resist a tropical rain of any conti-
nuance; yet I found that it kept out the :vet longer than any of
my other tents. 1 afterwards had it with me, on my return by
way of Bombay, where from the ship's labouring in heavy seas,
and it being the rainy season, it was wet both with salt and
fresh water,.yet on my arrival at the Cape, in December, 1810,
it was free frotu Mildew, and in lair condition. I therefore am.
led to believe, that the invention 'of this process is likely to
prove of great value.and utility.

Believe rie Sir,

Mr. Jamcs Jacks.
