only the kindness of friends, but the liberality of strangers. A very interesting collection of letters, many of them written in the Earl of Mar's own hand, and others dictated by him, is interwoven with the biography of that nobleman. These letters were written, in fact, for the information of the whole body of Jacobites, to whom they were transmitted through the agent of that party, Captain Henry Straiton, residing in Edinburgh. They form almost a diary of Lord Mar's proceedings at Perth. They are continued up to within a few hours of the evacuation of that city by the Jacobite army. For these curious and characteristic letters, pourtraying as they do, in lively colours, the difficulties of the General in his council and his camp, she is indebted to the friendship and mediation of the Honourable Lord Cockburn, and to the liberality of James Gibson Craig, Esq. To the Right Honourable the Earl of Newburgh, the descendant and representative of the Radcliffe family, her sincere and respectful acknowledgments are due for his Lordship's readily imparting to her several interesting particulars of the Earl of Derwentwater and his family. She owes a similar debt of gratitude to the Viscount Strathallan, for his Lordship's communication to her respecting the House of Drummond. To the Honourable Mrs. Bellamy, the descendant of Viscount Kenmure, she has also to offer similar acknowledgments, for information respecting her unfortunate ancestor; and for an original letter of his Lordship; and she must also beg to express her obligations to William Constable Maxwell, Esq., and to Mrs. Constable Maxwell, of Terregles, the descendants of the Earl of Nithisdale, for their courteous and prompt assistance. To James Craik, Esq., of Arbigland, Dumfriesshire, she is indebted for a correspondence which continues, as it were, an account of that family during the later part of the year 1745. To Sir Fitzroy Grafton Maclean, Bart., she owes the account of his clan and family, which has been printed for private circulation. She is also grateful to a descendant of the family of Lochiel, Miss Mary Anne Cameron, for some interesting particulars of the burning of Achnacarry, the seat of her ancestors. In some of these instances the information derived has not been considerable, owing to the total wreck of fortune, the destruction of houses, and the loss of papers, which followed the ruthless steps of the conquering army of the Duke of Cumberland. Most of the hereditary memorials of those Highland families who engaged in both rebellions, perished; and their representatives are strangely destitute of letters, papers, and memorials of every kind. The practice of burying family archives and deeds which prevailed during the troubles, was adopted but with partial advantage, by those who anticipated the worst result of the contest. In recalling with pleasure the number of those to whom the Author owes sincere gratitude for kindness and aid in her undertaking, the name of Charles Kirkpatrick Sharpe, Esq. renews the remembrance of that store of antiquarian information from which others, far more worthy to enjoy it than herself, have owed obligations. The Author has also most gratefully to acknowledge the very kind and valuable assistance of Archibald Macdonald, Esq., of the Register Office, Edinburgh, to whom she is indebted for several original letters; and of Robert Chambers, Esq., to whose liberality she is indebted for several of her manuscript sources, as well as some valuable advice on the subject of her work. To Dr. Irvine, Librarian of the Advocate's Library, Edinburgh, the Author offers, with the most lively pleasure, her sincere acknowledgments for a ready and persevering assistance in aid...
