Surely a useful suggestion is here given, for wrappers are useful things in their way, and, if made up tastefully, would attract attention to the photographic establishments that issue them. Photography is so closely allied to art that it is desirable to have everything in connection with it of an elegant and artistic description. The plain paper envelopes--gummed up at the ends, and difficult to get open again--are very inartistic, and anything but suitable to envelop such pretty little pictures as cartes-de-visite. Let photography encourage art and art manufactures, and art will enter into a treaty of reciprocity for their mutual advancement.--_Photographic News_, 1865. TO DUBLIN AND BACK, WITH A GLANCE AT THE EXHIBITION. The bell rings; a shrill shriek; puff, puff goes the engine, and we dart away from the station at Euston Square, provided with a return ticket to Dublin, issued by the London and North Western Railway, available for one month, for the very reasonable charge of £3, first-class and cabin; £2 7s. 6d. second class and cabin; or forty shillings third class and steerage, via Holyhead. These charges include steamboat fare and steward's fee. The Exhibition Committee have made arrangements with the railway companies to run excursion trains once a fortnight at still lower rates; twenty-one shillings from London to Dublin and back, and from other places in proportion. This ticket will be good for a fortnight, and will entitle the holder to another ticket, giving him two admissions to the Exhibition for one shilling. With the ordinary monthly ticket, which is issued daily, it is quite optional whether you go by the morning or evening train; but by all means take the morning train, so that you may pass through North Wales and the Island of Anglesea in daylight. Passing through England by Rugby, Stafford, Crewe, and Chester, nothing remarkable occurs during our rapid run through that part of the country. But an "Irish Gentleman," a fellow traveller, learning our destination, kindly volunteered to enlighten us how we could best see Dublin and its lions in the shortest possible time, and advised us by all "manes" not to "lave" Dublin without seeing "Faynix Park," and taking a car drive to Howth and other places round the "Bee of Dublin." Accordingly we agreed to take his advice; but as our primary object in visiting Dublin is to see the Exhibition, we will first attend to that on our arrival in the Irish capital; and if, after that, time will permit, the extraneous lions will receive our attention. First of all, we must describe how we got there, what we saw on the way, and what were our impressions on entering Dublin Bay.
