The young duke has several other residences. One of them is Kilkea Castle, County Kildare, which came into the family in the thirteenth century, with ninety thousand acres of farm land, which has just been sold to his tenants under the Wyndham Land Act for more than $6,000,000. The Duke of Leinster has also disposed of his farming lands in the neighborhood of Maynooth for more than $800,000. The estates commission, which has the responsibility of carrying out the provisions of the land act, has purchased more land from him than from any other landlord, and he has received from them in payment nearly one-fourth of the entire amount of money that has been paid under the act by the government. He has a plain but spacious town house on Dominick Street, Dublin, and Mrs. John W. Mackay now occupies his London residence, 6 Carlton House Terrace, under a long lease. His wealth is estimated at $50,000,000. He is unmarried, and has no attachments so far as known. His accumulation of titles is even greater than his wealth. He is the sixth duke of Leinster, which title dates from 1761, and was bestowed by Queen Anne; he is the twenty-fifth earl of Kildare, which title dates from 1316; and the thirty-first baron of Offlay, a title that has been in the family since 1168. He is the premier duke, the premier marquis, the premier earl, and the premier baron; the head of the Irish nobility. And all this rank and responsibility is borne by a frail boy of twenty-one. [Illustration: CARTON HOUSE, MAYNOOTH, COUNTY KILDARE; THE RESIDENCE OF THE DUKE OF LEINSTER] He spent the winter of 1907-8 in America, incognito, under the name of Maurice Fitzgerald. He and his tutor visited Quebec, Montreal, and Ottawa, and all the principal cities in the United States. They inspected Harvard, Yale, the University of Chicago, and Stanford University, for the young duke has recently taken a degree at Oxford, and was naturally curious to see some American institutions. He spent some time in New York, and was in Washington for a couple of days without disclosing his rank. He enjoyed himself immensely during the entire journey and escaped all the matchmakers, the lion hunters, and the society cormorants. He was not in search of a wife, but was seeking health and completing his education. I am told that he is an exceedingly sensible young fellow, modest, intelligent, thoughtful, and studious. He does not need to marry for wealth nor for position. He can pick his own wife, and has plenty of time to consider the choice.
