The third vice--for it is a vice--which we know to be prevalent in Wales, is the extreme dirt and untidiness of all the inhabitants. Go into any Welsh town or village, and observe the squalid shabby look of the houses and their tenants; visit their farms and cottages, and see the wretched filth in which men and animals herd together, and you will bear witness to the truth of our assertion. There is no spirit of order and improvement among them; every thing is done on the principle of the least possible present trouble. Were the Welsh blessed with the climate of Naples, they would, every one of them, become pure Lazzaroni,--as it is, they approximate to the Irish in their innate indolence and love of dirt. Whenever the commissioners for the health of towns receive their full power, they will have an Augean stable to cleanse, comprising the whole Principality. Even here, however, we are disposed to find some excuse for the people. They have so few resident gentry, at least of the larger proprietors; their country is so wild and so lonely; the difficulties of poverty and bad weather which they have to contend against are so great, that the philanthropical inquirer must make large allowances for them on this head. The commissioners found most of the country schools conducted in the most wretched buildings; but perhaps these buildings were some of the very best and cleanest in the district: they thought them neglected, and in bad repair; whereas the inhabitants might have supposed that they "had done the correct thing," and had adorned them in a style of lavish expenditure. We might go on multiplying our extracts and our comments _ad infinitum_, but we purposely abstain; and we shall conclude our review of these highly important documents with one or two inferences that seem to us obviously necessary.
