The external (and, as will be presently remarked, something more than the external) uniformity of his work is great, and its external conformity to the traditions and expectations of the time at which it first appeared is almost greater. A hasty judgment, and even one which, though not hasty, is not very keen-sighted, might see little difference between Crabbe and any poet from Pope to Goldsmith except the innovators. He is all but constant to the heroic couplet--the Spenserian introduction to _The Birth of Flattery_, the variously-grouped octosyllabic quatrains of _Reflections_, _Sir Eustace Grey_, _The Hall of Justice_, and _Woman_, with a few other deviations, being merely islets among a wide sea of rhymed decasyllabics constituting at least nineteen-twentieths of the poet's outpouring. Moreover, he was as a rule constant, not merely to the couplet, but to what has been called the "shut" couplet--the couplet more or less rigidly confined to itself, and not overlapping. But he did sometimes overlap, and either in fealty to Dryden, or from a secret feeling of the craving for freedom which his more lawless contemporaries expressed in other ways, he reverted to the Drydenian triplet and Alexandrine on which Pope had frowned. In Crabbe's couplet, too, there is something which distinguishes it from almost all others. This something varies very much in appeal. It is sometimes, nay, too often, a rather ludicrous something, possessing a sort of awkward prosaic "flop," which is excellently caricatured in _Rejected Addresses_. But it always shows signs of a desire to throw the emphasis with more variation than the icy uniformity of the Popian cadence admitted; and it is sometimes curiously effective.
