overburdening of landed property with debt partly by ordaining, in
the case of a debt secured over the land, the provisional transference

creditor, partly, in the case of a simple loan, by the rigour of the
proceedings in execution which speedily led to actual bankruptcy;
the latter means however, as the sequel will show, attained its
object but very imperfectly.
