Within a few years some efforts have been made to improve the sanitation of the city and the hygienic condition of the poor. Dirty alleys have been widened, model tenements built and drinking fountains supplied. At enormous cost the neighboring streams were turned into a valley, which made a natural reservoir seventeen miles from the city. Thence the water is brought through tunnels to filtering chambers, eight miles from town, from which it is distributed over the city. From the University we went down Dame Street to the Castle, used since the time of Elizabeth as the residence of the Lord Lieutenant. Here there are state apartments to be seen, and music to be heard in the beautiful chapel, but none of this to-day. The sun is setting, and as we whirl on past hospital, postoffice, Custom House, and convents, over the bridge and by the magnificent structure called the Four Courts, because there are held the courts of Queen’s Bench, Common Pleas, Chancery, and Exchequer, there is not time to drive inside the gate of the beautiful Phœnix Park and look at the obelisk that commemorates the victories of Wellington. That must be left for the morrow, as must the old Christ Church and St. Patrick’s Cathedral, whose ancient archepiscopal palace is now used as barracks for the police. In this cathedral are the tombs of Dean Swift and the Stella of his poetry. The structure is the most remarkable instance of complete restoration of our day, Mr. B. L. Guinness, M. P., having spent £150,000 in its restoration. He was knighted for his generosity, and it does not become us to suggest that the sum could have been better spent. We shall have to divide into two parties to-morrow, and while the artist and teacher go to examine the picture gallery and the schools, the others will get a look at the docks and the harbor, where, by aid of dredging machines, the sand is kept at bay, so that ships can now come up to the quays. Commerce still continues to be important, as Dublin is the avenue of supply for imports for the midland district, but manufacturers of woollen, cotton, silk, etc., are nearly extinct, though the general financial and commercial condition of Ireland is improved within the last twenty years.
