AT LOUGH MASK. Westport, Co. Mayo, Oct. 24. The result of several days incessant travelling in county Mayo is a very considerable modification of the opinion formed at the first glance at this, the most disaffected part of Ireland. On reaching Claremorris, in the heart of the most disturbed district, I certainly felt, and not for the first time, that as one approaches a spot in which law and order are supposed to be suspended the sense of alarm and insecurity diminishes, to put it mathematically, as the square of the distances. Even after a rapid survey of this part of the West I cannot help contrasting the state of public opinion here with that prevailing in Dublin. In the capital-outside of the Castle, where moderate counsels prevail-the alarmists appear to have it all their own way. I was told gravely that there was no longer any security for life or property in the West; that county Mayo was like Tipperary in the old time, only more so; and that if I would go lurking about Lough Mask and Lough Corrib it was impossible to prevent me; but that the chances of return were, to say the least, remote. It was in vain that I pointed out that every stone wall did not hide an assassin, and that strangers and others not connected either directly or indirectly with the land were probably as safe, if not safer, on a high road in Mayo than in Sackville-street, Dublin. It was admitted that, theoretically, I was quite in the right; but that like many other theorists I might find my theory break down in practice. I was entertained with a full account of the way in which assassinations are conducted in the livelier counties of Ireland, and great stress was laid upon the fact that the assassins were always well primed with the wine of the country, that is to say whisky, of similar quality to that known in New York as fighting rum, Jersey lightning, or torchlight procession. It was then impressed upon me that half-drunken assassins, specially imported from a distant part of the county to shoot a landlord or agent, might easily mistake a stranger for the obnoxious person and shoot him accordingly, just as the unlucky driver was hit in Kerry the other day instead of the land agent. Furthermore, I was taken to a gunsmiths in Dawson-street, where I was assured that the sale of firearms had been and was remarkably brisk, the chief demand being for full-sized revolvers and double-barrelled carbines. The weapon chiefly recommended was one of the latter, with a large smooth bore for carrying buck-shot and spreading the charge so much as to make the hitting of a man at thirty yards almost certain. The barrels were very short, in order that the gun might be convenient to carry in carriage or car. This formidable weapon was to be carried in the hand so as to be ready when opportunity served; a little ostentation as to ones habit of going armed being vigorously insisted on as a powerful deterrent. To any person unacquainted with the humorous side of the Irish character a morning spent in such converse as I have endeavoured to indicate might have proved disquieting enough; but those who know Irishmen and their ways at once enter into the spirit of the thing, and enjoy it as much as the untamable jokers themselves....
