The machinery in the woollen factories of Ireland is certainly inferior to that of our English neighbours, and the decline of the trade renders improvement difficult, if not altogether hopeless. Power-looms for the weaving of woollen cloth, so generally at work at the other side of the Channel, have been only this year introduced for the first time to this country by Mr Moore, proprietor of the Milltown factory near Dublin; and that Irish mechanists are not inferior to any others, is evidenced by the fact that the power-looms erected at Milltown are vastly superior to those imported, and which were on the most improved construction. Whether the experiment will have any effect in reviving this sinking business, remains to be seen; but it is much to be feared that as a great branch of trade it has deserted our shores altogether; certain it is, that the great factory at Celbridge (within ten miles of Dublin), which was dismantled about five years since, employed so lately as the year 1829 more looms than are now (1840) at work in the whole county of Dublin, probably in the entire province of Leinster, and yet the introduction of machinery could be effected much more easily in Ireland than almost any where else, in consequence of the absence of a manufacturing population, whose interests might be so compromised as to make them adverse to such change, and water power, so much cheaper than steam, is both abundant and unemployed. N. ENIGMA, BY P. M’TEAGUE, ESQ. Who or what am I, that, dwelling amongst the most humble, can associate with the highest? I am low in the scale of rank, but at the head of my race, and the most ancient of my tribe; the offspring and representative of want, and despised by multitudes, yet of regal descent. I have the likeness of woman and man, but I am neither man nor woman. I have neither father nor mother, and I am childless. I have the appearance of a potentate, yet I am not a potentate, but the companion of the lowly, and their most frequent visitor and guest. It is my destiny to live equally in palaces and farm-houses, jails and hovels. I am a traveller, though one who is always obliged to journey blindfold, and sometimes bound in cords with vulgar companions, and strictly guarded. No creature undergoes greater vicissitudes. I am the attendant of most that walk, sail, and ride. I am attached to the pedestrian, yet generally kept in confinement; or when at times liberated, exposed to the rudest scoffs and sports of the vulgar, who toss me up in the air, pelt me with sticks and stones, tumble me on the earth, and stamp on me; and if I am raised again, it is either to endure a repetition of insult, or administer to the cupidity of vagabonds.
