On Sunday, the 30th of January, the immense masses of ice that floated from the upper parts of the river, in consequence of the thaw on the two preceding days, blocked up the Thames between Blackfriars and London Bridges; and afforded every probability of its being frozen over in a day or two. Some adventurous persons even now walked on different parts, and on the next day, Monday the 31st, the expectation was realized. During the whole of the afternoon, hundreds of people were assembled on Blackfriars and London Bridges, to see people cross and recross the Thames on the ice. At one time seventy persons were counted walking from Queenhithe to the opposite shore. The frost of Sunday night so united the vast mass as to render it immovable by the tide. On Tuesday, February 1, the river presented a thoroughly solid surface over that part which extends from Blackfriars Bridge to some distance below Three Crane Stairs, at the bottom of Queen-street, Cheapside. The watermen placed notices at the end of all the streets leading to the city side of the river, announcing a safe footway over, which attracted immense crowds, and in a short time thousands perambulated the rugged plain, where a variety of amusements were provided. Among the more curious of these was the ceremony of roasting a small sheep, or rather toasting or burning it over a coal fire, placed in a large iron pan. For a view of this extraordinary spectacle, sixpence was demanded, and willingly paid. The delicate meat, when _done_, was sold at a shilling a slice, and termed “_Lapland mutton_.” There were a great number of booths ornamented with streamers, flags, and signs, and within them there was a plentiful store of favourite luxuries with most of the multitude, _gin_, _beer_, and _gingerbread_. The thoroughfare opposite Three Crane Stairs was complete and well frequented. It was strewed with ashes, and afforded a very safe, although a very rough path. Near Blackfriars Bridge, however, the way was not equally severe; a plumber, named _Davis_, having imprudently ventured to cross with some lead in his hands, sank between two masses of ice, and rose no more. Two young women nearly shared a similar fate; they were rescued from their perilous situation by the prompt efforts of two watermen. Many a fair nymph indeed was embraced in the _icy arms_ of old Father Thames;--three young quakeresses had a sort of semi-bathing, near London Bridge, and when landed on terra-firma, made the best of their way through the Borough, amidst the shouts of an admiring populace. From the entire obstruction the tide did not appear to ebb for some days more than one half the usual mark.
