4thly, The Idyllium,—­descriptive chiefly either of the processes and appearances of external nature, as the ‘Seasons’ of Thomson; or of characters, manners, and sentiments, as are Shenstone’s ‘Schoolmistress,’ ‘The Cotter’s Saturday Night’ of Burns, ‘The Twa Dogs’ of the same Author; or of these in conjunction with the appearances of Nature, as most of the pieces of Theocritus, the ‘Allegro’ and ‘Penseroso’ of Milton, Beattie’s ‘Minstrel,’ Goldsmith’s ’Deserted Village.’  The Epitaph, the Inscription, the Sonnet, most of the epistles of poets writing in their own persons, and all loco-descriptive poetry, belong to this class.

5thly, Didactic,—­the principal object of which is direct instruction; as the Poem of Lucretius, the ‘Georgics’ of Virgil, ‘The Fleece’ of Dyer, Mason’s ‘English Garden,’ &c.

And, lastly, philosophical Satire, like that of Horace and Juvenal; personal and occasional Satire rarely comprehending sufficient of the general in the individual to be dignified with the name of poetry.

Out of the three last has been constructed a composite order, of which Young’s ‘Night Thoughts,’ and Cowper’s ‘Task,’ are excellent examples.

It is deducible from the above, that poems, apparently miscellaneous, may with propriety be arranged either with reference to the powers of mind predominant in the production of them; or to the mould in which they are cast; or, lastly, to the subjects to which they relate.  From each of these considerations, the following Poems have been divided into classes; which, that the work may more obviously correspond with the course of human life, and for the sake of exhibiting in it the three requisites of a legitimate whole, a beginning, a middle, and an end, have been also arranged, as far as it was possible, according to an order of time, commencing with Childhood, and terminating with Old Age, Death, and Immortality.  My guiding wish was, that the small pieces of which these volumes consist, thus discriminated, might be regarded under a twofold view; as composing an entire work within themselves, and as adjuncts to the philosophical Poem, ‘The Recluse.’  This arrangement has long presented itself habitually to my own mind.  Nevertheless, I should have preferred to scatter the contents of these volumes at random, if I had been persuaded that, by the plan adopted, any thing material would be taken from the natural effect of the pieces, individually, on the mind of the unreflecting Reader.  I trust there is a sufficient variety in each class to prevent this; while, for him who reads with reflection, the arrangement will serve as a commentary unostentatiously directing his attention to my purposes, both particular and general.  But, as I wish to guard against the possibility of misleading by this classification, it is proper first to remind the Reader, that certain poems are placed according to the powers of mind, in the Author’s conception, predominant in the production of them; predominant, which implies
