CATHEDRAL OF MONAGHAN.- The town of Monaghan is the principal burgh of the county of that name; and the Catholic Bishop of the diocese of Clogher has his residence there. The sketch given above is a true picture of the magnificent new cathedreal, completed during the long regime of the late Right Rev. Bishop Donnelly-one of the most patriotic of the Irish hierarchy-and dedicated only a few years ago-a short time before the lamented prelate's death. The cathedral is one of the most artistic of the modern ecclesiastical edifices of Ireland, and its interior finish is in all respects equal to its imposing exterior. Monaghan county was the patrimonial territory of the brave McMahons of Ulster, one of whose principal chiefs, Hugh Roe McMahon, was basely murdered by order of the English Lord Deputy, Fitzwilliam, who wished to gain possession of his lands, A. D. 1590. The name Monaghan comes from the Gaelic Muineach-an-Place of the Little Hills, which exactly describes the configuration of the country. Sir Charles GAvan Duffey, late premier of the colony of Victoria, and one of the most renowned of the Young Ireland poets and prose writers, and Terence Bellew MacManus-one of the leaders of the '48 "rising" in Ireland-were both born in Monaghan.
