A word as regards some of the later sources of my information. The Pelham MSS. were not accessible when Mr. Froude wrote. Thomas Pelham, second Earl of Chichester, was Irish Secretary from 1795 to 1798, but his correspondence until 1826 deals largely with Ireland, and I have read as much of it as would load a float. Another mine was found in the papers, ranging from 1795 to 1805, which filled two iron-clamped chests in Dublin Castle, guarded with the Government seal and bearing the words 'Secret and Confidential: Not to be Opened.' These chests were for a long time familiar objects exteriorly, and when it was at last permitted to disturb the rust of lock and hinge, peculiar interest attended the exploration. Among the contents were 136 letters from Francis Higgins, substantially supporting all that I had ventured to say twenty years before in the book which claimed to portray his career. But neither the Pelham Papers in London nor the archives at Dublin Castle reveal the great secret to which Mr. Froude points. That so many documents have been preserved is fortunate. Mr. Ross, in his preface to the Cornwallis Correspondence, laments that 'the Duke of Portland, Lord Chancellor Clare, Mr. Wickham, Mr. King, Sir H. Taylor, Sir E. Littlehales, Mr. Marsden, and indeed almost all the persons officially concerned, appear to have destroyed the whole of their papers.' He adds: 'The destruction of so many valuable documents respecting important transactions cannot but be regarded as a serious loss to the political history of these times.' I have freely used the Registry of Deeds Office, Dublin--a department peculiar to Ireland. Originating in penal times, its object was to trace any property acquired by Papists--such being liable to 'discovery and forfeiture.' This office served as a valuable curb in the hands of the oppressor, and ought to prove a not less useful aid to historic inquirers; but, hitherto, it has been unconsulted for such purposes. Few unless legal men can pursue the complicated references and searches, and--unlike the Record Office--fees attend almost every stage of the inquiry. Here things stranger than fiction nestle; while the genealogist will find it an inexhaustible store.
