In the cavalry encampment the leaves lay thick around the unfortunate horses exposed to the weather with miserably insufficient covering. There was a general air of wetness and wretchedness from the infantry to the cavalry barracks, and some misgivings were entertained as to the condition of the garrison of Lough Mask House. General opinion has set in decidedly against the Ulster contingent: horse and foot, and police, magistrates and floating population unite in wishing the Ulster Orangemen "five fathoms under the Rialto." In the language of those who dwell habitually on the banks of the river the wish is epigrammatically expressed, "May the Robe be their winding-sheet." Originally imagined as a scheme to force the hand of the Government, the Ulster invasion has been so far successful. The great actual mischief has been already done. According to public opinion in Mayo, the Government had no more than the traditional three courses open to them--they could have let armed Ulster come in hundreds or thousands, an invading force, and civil war would have ensued; they could have allowed the small number of labourers really needed by Mr. Boycott to arrive by threes and fours, at the risk of not getting alive to Lough Mask at all; and they could do as they have done. The probable effect of the movement, if any, will be to bring Mr. Somerset-Maxwell to the fore at the next contest for the county of Cavan. It may be imagined that the picked men of Monaghan are not very pleased at playing second fiddle to an electioneering scheme. Concerning Cavan, the hope of a fight between the men of the two counties has by no means died away. To do justice to the Ulster men, they displayed a great deal of earnestness at Lough Mask House this morning. In the midst of a hurricane a large number of them went bravely out to a potato field and worked with a conscience at getting out the national vegetables, which ran a risk of being completely spoiled by the rain. The potatoes, however, might, as Mr. Boycott opined, have been spoiled if they had remained in the ground, and might as well be ruined in one way as the other.
