The message of President Polk is regarded in Ireland with no ill will. Our presss— which is whatever it wants, a most faithful mirror of the Irish mind— regards it as a national defiance to England. We are inclined to think England will not take u the gauntlet. But if she does, there will be other questions to settle as well as the Oregon question. We consider our title perfectly clear to every inch of Ireland; while you cry America for the Americans, we cry Ireland for the Irish; we will give a year’s notice to quit the joint occupancy of the Union, simultaneously with yours to terminate the copartnership in Oregon.
