WE had lately missed our friend Mr. L. P. CLOVER, from his establishment under the Astor-House, in Vesey-street, and were ignorant of his whereabout; until happening one day to pass Dr. LYELL'S church in Anthony-street, near Broadway, we observed, near the door of a building adjoining that edifice, a couple of large paintings, representing the Falls of Niagara. Entering to inquire the name of the artist, we opened upon Mr. CLOVER, which 'fully accounted' for the presence at his door of works of art; for although his establishment is better known for its excellent looking-glasses and picture-frames, for the sale of which, on reasonable terms, it has become so popular, yet we have been often indebted to the proprietor's taste and enterprise for the enjoyment of some of the best paintings to be met at any similar place in the metropolis. To test the justice of our commendations, let our town readers drop in at Number eighty-three Anthony-street, and examine VANDERLYN'S Views of the Great Cataract, and several of WARD'S fine landscapes. * * * WE hear of various changes and some deaths among our contemporaries. Our friend 'SARGENT'S Magazine' has been swallowed up in 'GRAHAM'S;' two or three 'lady-periodicals,' as they are termed, have been similarly wedded; the 'Southern Literary Messenger,' since the death of its amiable and persevering proprietor, has been advertised for sale at public auction; the Charleston 'Magnolia' is we hear to be discontinued: Mr. SIMMS recently transferred its editorial functions. The 'Orion,' we are informed, will commence its third volume in September, with increased attractions, literary and pictorial. How many Magazines have arisen, struggled, and fallen, within the last ten years, that were going to throw the 'Old KNICK.' into the back-ground, and darken his out-goings! We could at this moment count up a score of such upon our fingers; and yet MAGA 'flourishes in immortal youth!' 'Be virtuous, and you will be happy;' 'Rome was not built in a day;' and so forth. * * * 'REMEMBER that thou keep holy the Sabbath-Day,' is a lesson beautifully enforced in the following lines by Sir MATTHEW HALE. We give them in place of our Baltimore correspondent's remarks upon '_Sunday in the Country_,' in our last number: 'A SABBATH well spent Brings a week of content, And health for the toils of to-morrow; But a Sabbath profaned, Whatsoe'er may be gained, Is a certain forerunner of sorrow.'
