It was night before the three weary travellers reached Sand- 

 Rock Hotel. Beauteous spot! — UnderclifF, never to be for- 

 gotten ; — when first I saw thy bewitching face, the full-moon 

 was riding triumphantly over the ocean, silvering the multitu- 

 dinous ripples with her reflected image, and making a broad and 

 glorious track of ever-varying light — and thou wast bathed in 

 more than ordinary splendour by the brightness of her beams ! 

 After roughing it on the ocean, and among the cliffs of Fresh- 

 water and the Needles, the quietude and luxury of this spot 

 seemed to invite repose ; we tarried there many days ; and 

 then, walking through Appeldurcombe and Newport, arrived 

 at Cowes ; — and there, taking ship, sailed to Portsmouth, and 

 so returned. 



I am, Sir, Your's, &c.
