But we must stop. To go on in this way describing all the beautiful works of art in the Dublin Exhibition would fill a volume. Already we have allowed our admiration to carry us beyond the limits we had assigned ourselves. We have been tempted to describe more than photographic works, but none that have not a value artistically or otherwise to photographers. We recommend all our readers that possibly can to go and see for themselves. The trip is a very pleasant one, and need not be expensive; nor need much time be spent unnecessarily. A week's absence from business will give you five clear days in Dublin, the other two only being occupied in travelling. Five days will be amply sufficient to see the Exhibition and the "extraneous lions" of Dublin also. If your time is limited, give a carman a job to "rowl" you to the principal places of interest. But "by all means" select a rough, ragged, red-headed, laughing-faced Irishman for your jarvey, and depend upon it he will keep you in good humour during the whole of your trip. And every time you come to a public-house he will say his "horse wants a dthrink," and "Won't yer honours have a dthrop?" as if he was going to stand treat; but of course you know what he means; besides, the idea of allowing a carman to treat his fare is not to be entertained for a moment, nor can you resist the good-humoured intimation of his desire to drink your health, for which honour, as a matter of course, you pay costs. Having endeavoured to conduct our readers to Dublin, and give them a glance at the Exhibition, photographically and generally, we shall now take our leave of the capital of Ireland, and return to town in much the same manner as we went. We leave the Irish capital at 1.30 in the afternoon, and, after a pleasant and quiet run across the Channel, enter Holyhead harbour about seven o'clock. This arrangement gives you an opportunity of seeing the Welsh coast to the best advantage as you approach. Stepping into the train which is waiting our arrival, we are speedily on our way home. At Rugby we have to change, and wait a little; but before leaving there we pass the sign which only old masons and travellers know, and are provided with a first-class bed and _board_, and so make ourselves comfortable for the night. We know nothing more of the remainder of the journey. Old Somnus has charge of us inside, and an old kind-hearted guard takes care of us outside, until we are aroused by the guard's "Good morning, gentlemen!" about six o'clock, a.m., within a few miles of Euston Square. In conclusion, we sincerely recommend as many of our readers as can to take a trip "to Dublin and back," and a glance at the Dublin International Exhibition. PHOTOGRAPHY IN THE NORTH.
