a payment certain, whether the tradesman gets or loses, and as he may
often get double, so sometimes he loses, and then his interest is a
double payment; it is a partner with him under this unhappy
circumstance, namely, that it goes halves when he gains, but not when he
loses.

2. The lender calls for his money when he pleases, and often comes for

Indeed, this article would require not a letter, but a book by itself;
and the tragical stories of tradesmen undone by usury are so many, and
the variety so great, that they would make a history by themselves. But
it must suffice to treat it here only in general, and give the tradesmen
a warning of it, as the Trinity-house pilots warn sailors of a sand, by
hanging a buoy upon it, or as the Eddystone light-house upon a sunk
