_Discovery of Glamorgan's treaty._--These suspicions were much aggravated by a second discovery that took place soon afterwards, of a secret treaty between the Earl of Glamorgan and the confederate Irish catholics, not merely promising the repeal of the penal laws, but the establishment of their religion in far the greater part of Ireland.[318] The Marquis of Ormond, as well as Lord Digby who happened to be at Dublin, loudly exclaimed against Glamorgan's presumption in concluding such a treaty, and committed him to prison on a charge of treason. He produced two commissions from the king, secretly granted without any seal or the knowledge of any minister, containing the fullest powers to treat with the Irish, and promising to fulfil any conditions into which he should enter. The king, informed of this, disavowed Glamorgan; and asserted in a letter to the parliament that he had merely a commission to raise men for his service, but no power to treat of anything else, without the privity of the lord lieutenant, much less to capitulate anything concerning religion or any property belonging either to church or laity.[319] Glamorgan however was soon released, and lost no portion of the king's or his family's favour. This transaction has been the subject of much historical controversy. The enemies of Charles, both in his own and later ages, have considered it as a proof of his indifference at least to the protestant religion, and of his readiness to accept the assistance of Irish rebels on any conditions. His advocates for a long time denied the authenticity of Glamorgan's commissions. But Dr. Birch demonstrated that they were genuine; and, if his dissertation could have left any doubt, later evidence might be adduced in confirmation.[320] Hume, in a very artful and very unfair statement, admitting the authenticity of these instruments, endeavours to show that they were never intended to give Glamorgan any power to treat without Ormond's approbation. But they are worded in the most unconditional manner, without any reference to Ormond. No common reader can think them consistent with the king's story. I do not, however, impute to him any intention of ratifying the terms of Glamorgan's treaty. His want of faith was not to the protestant, but to the catholic. Upon weighing the whole of the evidence, it appears to me that he purposely gave Glamorgan, a sanguine and injudicious man, whom he could easily disown, so ample a commission as might remove the distrust that the Irish were likely to entertain of a negotiation wherein Ormond should be concerned; while by a certain latitude in the style of the instrument, and by his own letters to the lord lieutenant about Glamorgan's errand, he left it open to assert, in case of necessity, that it was never intended to exclude the former's privity and sanction. Charles had unhappily long been in the habit of perverting his natural acuteness to the mean subterfuges of equivocal language.
