Irish antiquaries for generations have squabbled over these famous "Pillar Towers of Ireland," but the general trend of scientific opinion is that they are of early Christian origin. Father Matt Horgan, a famous Munster antiquary, humorously started the theory that they were built to puzzle posterity, which they have very successfully done. ~Lucan~ is a health resort, possessing a sulphur spa, and situated in a well-wooded country above the Liffey. The Hydropathic stands well sheltered and commanding a splendid view. The drives in the district are many, and the antiquarian will find much of interest. In Lord Annaly's demesne are the remains of an early Norman castle, and in the vicinity is an ancient Rath and souterraine. The drive to the Salmon Leap, at Leixlip, should not be missed. Near by is ~Castletown~, the palatial mansion of the Connolly family, and a grotesque structure known as "Connolly's Folly," which was built in the time of the famine of "Black '47" to give employment. Here, too, the great Dean of St. Patrick's beguiled his time at "The Abbey," the home of Esther Vanhomrigh, the "Vanessa" of his strange life. From Lucan Maynooth may be reached. Here is St. Patrick's National College for the education of priests for the Catholic Church, originally founded on a Government grant. "Carton House," in the vicinity, is the residence of the Dukes of Leinster. It is surrounded by beautiful parks, well planted, among the trees the royal oaks, for which Kildare was celebrated, being conspicuous. ~Straffan~ may be called a "hunting village," as the meets of the famous "Killing Kildares" most usually take place in its neighbourhood. Here, too, are the seats of Lords Cloncurry and Mayo. The thriving market town of ~Naas~ is two miles from Sallins, and is the railway station for Punchestown, the great steeplechase meeting of the Kildare Hunt. Long centuries ago it was an historic spot--"Naas of the Kings." From the station may be seen the Hill of Allen, rising like a sentinel on the mearings of the "Great Plain of Ireland." ~Harristown~, the second station on a branch line, is about three miles from Poulaphouca Waterfall. The road to the Falls leads through the picturesque village of Ballymore-Eustace, situated on a bank at a bend in the river Liffey. The view from the river below the Falls is very impressive. Tullow is the terminus of this branch of the line. It is a good business town, and the river Slaney affords excellent trout fishing. Within half-an-hour's walk from Sallins is Bodenstown Churchyard, where Theobald Wolfe Tone, the founder of the United Irish Organisation of 1798, is buried. He was the most desperate man who ever crossed the path of the English Government in Ireland. "The most extraordinary man I ever met," is the verdict of the Duke of Wellington. "He went to France with but one hundred guineas in his pocket, and induced Bonaparte, by his single unaided efforts, to send three
