manifest reasons why, after a certain point, he is likely to
fail. If the mine be not wrought out, the strength and capacity
of the miner become necessarily exhausted. If he closely
imitates the narratives which he has before rendered successful,
he is doomed to "wonder that they please no more." If he
struggles to take a different view of the same class of subjects,
he speedily discovers that what is obvious, graceful, and
natural, has been exhausted; and, in order to obtain the
indispensable charm of novelty, he is forced upon caricature,
and, to avoid being trite, must become extravagant.

It is not, perhaps, necessary to enumerate so many reasons why
the author of the Scottish Novels, as they were then exclusively
termed, should be desirous to make an experiment on a subject
purely English. It was his purpose, at the same time, to have
rendered the experiment as complete as possible, by bringing the
intended work before the public as the effort of a new candidate
for their favour, in order that no degree of prejudice, whether
favourable or the reverse, might attach to it, as a new
production of the Author of Waverley; but this intention was
afterwards departed from, for reasons to be hereafter mentioned.

The period of the narrative adopted was the reign of Richard I.,
