oblige him, turned their hands from the grey hard well-burnt bricks to
the soft _sammel_[9] half-burnt bricks, which they were glad to dispose
of, and which nobody that had understood them would have taken off their
hands.

I mention these lower things, because I would suit my writing to the
understanding of the meanest people, and speak of frauds used in the
most ordinary trades; but it is the like in almost all the goods a
tradesman can deal in. If you go to Warwickshire to buy cheese, you
demand the cheese 'of the first make,' because that is the best. If you
go to Suffolk to buy butter, you refuse the butter of the first make,
because that is not the best, but you bargain for 'the right rowing
butter,' which is the butter that is made when the cows are turned into
the grounds where the grass has been mowed, and the hay carried off, and
grown again: and so in many other cases. These things demonstrate
the advantages there are to a tradesman, in his being thoroughly
informed of the terms of art, and the peculiarities belonging to every
particular business, which, therefore, I call the language of trade.

As a merchant should understand all languages, at least the languages of
those countries which he trades to, or corresponds with, and the customs
and usages of those countries as to their commerce, so an English
tradesman ought to understand all the languages of trade, within the
circumference of his own country, at least, and particularly of such as
he may, by any of the consequences of his commerce, come to be any way
concerned with.

Especially, it is his business to acquaint himself with the terms and
trading style, as I call it, of those trades which he buys of, as to
those he sells to; supposing he sells to those who sell again, it is
