P.S. This is a sleepy article; and I would warn its reader to endeavour not to fall asleep over it, and thus endanger his falling over his chair; and lest some familiar friend or _chere amie_ should, finding his instructions in his hand, take the opportunity of making the experiment, and may be create a little jealous quarrel or so. * * * * * SONNET TO THE RIVER ARUN. (_For the Mirror._) Pure Stream! whose waters gently glide along, In murmuring cadence to the Poet's ear, Who, stretch'd at ease your flowery banks among, Views with delight your glassy surface clear, Roll pleasing on through Otways sainted wood; Where "musing Pity" still delights to mourn, And kiss the spot where oft her votary stood, Or hang fresh cypress o'er his weeping urn;-- Here, too, retir'd from Folly's scenes afar, His powerful shell first studious Collins strung; Whilst Fancy, seated in her rainbow car, Round him her flowers Parnassian wildly flung. Stream of the Bards! oft Hayley linger'd here; And Charlotte Smith[1] hath grac'd thy current with a tear. _The Author of "A Tradesman's Lays." No. 85, Leather Lane._ [1] This charming, accomplished poetess has addressed one of her most beautiful "Elegiac Sonnets" to this inspiring River. Her tender image of the "infant Otway" is, however, borrowed from a stanza in Collins's inimitable "Ode to Pity:"-- "Wild Arun, too, has heard thy strains And echo 'midst my native plains Been sooth'd by Pity's lute; There first the wren thy myrtles shed On gentlest Otway's _infant head_-- To him thy cell was shown," &c. * * * * * RETROSPECTIVE GLEANINGS. * * * * * ANCIENT BLACK BOOKS, &c. (_For the Mirror._) The Black Book of the Exchequer is said to have been composed in the year 1175, by Gervase of Tilbury, nephew of King Henry the Second. It contains a description of the court of England, as it then stood, its officers, their ranks, privileges, wages, perquisites, powers, and jurisdictions; and the revenues of the crown, both in money, grain, and cattle. Here we find, that for one shilling, as much bread might be bought as would serve a hundred men a whole day; and the price for a fat bullock was only twelve shillings, and a sheep four, &c. At the end of this book are the Annals of William of Worcester, which contain notes on the affairs of his own times. The Black Book of the English Monasteries was a detail of the scandalous enormities practised in religious houses: compiled by order of the visiters, under King Henry the Eighth, to blacken them, and thus hasten their dissolution. Books which relate to necromancy are called Black Books.
