TUE GREAT SECRET OF TRADE.
Many houses make a mystery of their business, and one
-41(1 think they were in possession of some great secret, that none
telt themselves must know. We see nothing in fair trading that re-
tZee mystery—we understand no trade secrets—all we know our
tie touters may know, for we desire to be candid. Everybody won-
-1104 licm we can sell good articles so cheap. They can all understand
, it is that peocan sell cheap when the atticles are bad. There
peoe difficulty in comprelunding how common things are sold at low
; but the wonder is how we can turn out Clothes of the best
4:4,t3' at the small prices we charge. We hesitate not to explain
at
do it. First, we buy very large quantities of material, uot
else could,
he first price, but often at considerably less than anybody
uld,
y because we buy snore largely than anybody else can.
4; We have an immense number of first-rate hands, who are equal
sta„ait,Y in the trade in the quality of their work, and these are con-
he' 13' employed all the year round. Thirdly, we employ a number of
14,1aost steady and talented cutters and litters in the kingdom, and
ItViatend the work ourselvess upon the premises. But, after all, there
ti„ Beeret—a something which enables us to sell a better and a
kaper article than anybody, and that is, we are content with
141,,u Profits, that is the grand secret. We fear no competition in
ka'Liig, making, and selling. Our clothes are equal in quality,
tiot:Zrel,and style to those ior which most tailors charge mere than
bloie price. The vast business we do renders our small profits tar
loin. advantageous than other people's large ones, and with an es-
tipa. shment unrivalled in extent, in convenience, and in situation,
Moreover with capital that will always command the best
e
let,ea in the market at the most favourable prices, we can chal-
stoee the whole trading community to produce goods at the price
doubt, quality which we are selling hourly. We only ask those
$OO4ll to visit either of our establishments, and inspect the
tilt. • We do not ask them to buy, they may do that at some future
or not at all; but we do earnestly desire to make every one
qaillted with our establishments, and our mode of doii,g business;
With this expression of our wishes subscribe ourselves,
