The wages of such labourers, it may be remarked in passing, are, for men, 2f. 50c., and for women 1f. 50c., respectively per day. Here, too, we begin to have indications of something besides agricultural industry. The smell of petroleum assails the olfactory organs, and we often see carts drawn by oxen or buffaloes, containing one or more barrels of the mineral oil; whilst on the hills are to be seen the rude wooden structures which cover the wells, and roads or tramways along which the oil is carried into the valley below. As we advance further into the mountains, evidences of another mineral treasure present themselves. This is rock-salt, of which cartloads may be seen moving to the railway stations or piled up in various places. This valuable mineral in no way resembles our rock-salt, and the large blocks might easily be mistaken for granite or rough unpolished marble. The appearance and mode of working one of the great mines of the country will be described hereafter; and the chief localities in which salt and petroleum are raised will be found on our geographical map. The principal salt mines are the _Doftana_ (Prahova) near Campina, _Poiana_, and _Slanic_ (Prahova), _Ocnele_ Mari (Rămnicu), _Targu Ocna_ (Bacau). The chief petroleum wells are also near Campina, at _Colibasu_, _Pacuri_, _Doftanet_, _Telega_ &c., _Moineste_, &c., (Bacau). There are refineries at Tirgovistea, Peatra. Ploiesti, &c. [Footnote 9: The Roumanians recognise that a great part of the country is much neglected, and that weeds are allowed to grow to the detriment of agriculture. The _Indépendance Roumaine_, September 13 [25], 1881, had a strong article on the subject.] [Footnote 10: We do not intend to discuss this question, which is so interesting to Roumanians, but we cannot help drawing attention to Paget's remarks on the subject. He says, in one of his headings, 'Wallacks of Dacian, not Roman origin;' then (p. 112) lie gives woodcuts of two heads with moustache only (sketched without any reference to the question), and somewhat resembling our cut, and leaves his readers to compare them with the figures on Trajan's Column. He says that he feels satisfied they will agree with his view. They do not, however, in the least resemble either the Romans with bare, or the Dacians with bearded faces, on the column, and throw no light whatever upon the vexed question. The general opinion of persons who have observed the peasantry is that those of the mountain districts afford, in their type of face, habits, and some words, the best illustrations in support of the Daco-Roman hypothesis.]
