The few political speeches of the week have not been,
on the whole, very important. The Cutlers' Feast at Sheffield yesterday week gave Mr. Roebuck occasion to bark very furiously at some party (unnamed) which he imagines to be intent on undermining I the military and naval strength of Great Britain. The Marquis of Hartington used the same occasion to entreat all parties to lay aside their political rivalries on the Irish land question, the bet- ter to secure the defeat of all doctrines and principles "hostile not only to the interests of landowners, but of capitalists of every description,"—a summons which, as we have elsewhere pointed out, is certain to be interpreted, however it was meant, as a signal of distress from the high landed interest in the Cabinet to the same interest on the opposite side of the House,—i. e., as the first ominous crack in the cohesion of the ruling party.
