An obelisk 140 feet in height, supported upon open arches, and surrounded by a grove of full-grown trees, stands on a hill near Maynooth, and can be seen to advantage both from the Midland and the Great Southern Railway.  It is usually known as “Lady Conolly’s Monument.”  From its being built without any apparent utility, illnatured people sometimes call it “Lady Conolly’s Folly.”  It is said to have been designed by Castelli (Anglicised “Castells"), the architect of Carton, Castletown House, and Leinster House, Kildare Street, now the Royal Dublin Society House.  It bears on the keystones of its three principal arches the suggestive date, “1740.”  It was erected to give employment to the starving people in that year, not by Lady Louisa Conolly, as is generally supposed, but by a Mrs. Conolly, as the following information, kindly supplied by the Marquis of Kildare, will show:—­

“I find in my notes,” says the Marquis, “that the obelisk was built by Mrs. Conolly, widow of the Rt.  Hon. Wm. Conolly, Speaker of the Irish House of Commons.  She had Castletown for her life, and died in 1752, in her ninetieth year.  Mrs. Delany, in her Autobiography, vol. iii, p. 158, mentions that her table was open to her friends of all ranks, and her purse to the poor....  She dined at three o’clock, and generally had two tables of eight or ten people each....  She was clever at business....  A plain and vulgar woman in her manners, but had very valuable qualities. 1740 was a year of great scarcity, and farmers were ploughing their wheat in May to sow summer barley.  In March Mrs. Conolly’s sister, Mrs. Jones, wrote to another sister, Mrs. Bound, that Mrs. Conolly was building an obelisk opposite a vista at the back of Castletown House, and that it would cost L300 or L400 at least, and she wondered how she could afford it.  The nephew of the Speaker, also the Rt.  Hon. Wm. Conolly, lived at Leixlip Castle till he succeeded to Castletown in 1752.  He married Lady Anne Wentworth, daughter of an Earl of Strafford.  His son was the Right Hon. Thos.  Conolly, who married Lady Louisa Lennox, daughter of the Duke of Richmond.  From her Castletown passed to the father of the present Mr. Conolly, after the death of Lady Louisa.”

Mrs. Jones must have made a very erroneous guess at the expense of building the obelisk, even at that time; now, instead of three or four hundred pounds, double as many thousands would scarcely build it.  Although erected by Mrs. Conolly, it stands on the Duke of Leinster’s property.  The site is the finest in the neighbourhood, and she obtained it from the Earl of Kildare, by giving him a portion of the Castletown estate instead.  Lately those two pieces of ground have been re-exchanged, and when they came to be measured, they were found to be of exactly the same extent.

[24] The coming of the thaw was indicated by some accidents on the ice.  Under date 10th Feb. it was reported from Derry that the ice gave way there, and several persons were drowned.  In Dublin, at the same date, a man was also drowned who attempted to cross the river on the ice near the Old Bridge.  But a boy was more fortunate.  He, too, was on the ice on the Liffey, and the part on which he stood becoming detached was driven by the current through Ormond and Essex Bridges; he kept his position, however, on the floating ice till he was taken off in a boat.
