Between Bishop Colenso and the volcanoes of Central France, and between these and ‘Rogation Days,’ there would at first sight seem to be but little connection. Nevertheless, a statement made by the Bishop was the cause of some curious information, which had previously been known to but few, being generally circulated; and as it then appeared only in one or two newspapers, and at different times, it may be useful to give a résumé of the controversy in a more permanent form. The Bishop, referring to Lyell (‘Elementary Geology,’ pp. 197, 198), adduced the exitstence of cones of loose scoriæ and pumice in Auvergne and Languedoc as an argument against the Noachian Deluge; because these, which ‘must have been formed ages before’ that happended, did not show the slighttest sign of having ever been disturbed. In the course of the endless controversy which has arisen from the Bishop's works, a Mr. E. L. Garbett addressed a rather angry letter to the ‘Guardian’ newspaper (Aug.24, 1864), taxing the Bishop with wilfully shutting his eyes to the fact that there had been eruptions in these districts in the fifth century, which had given rise to the ecclesiastical fasts commonly called ‘Rogation Days.’ The Bishop replied in a letter, which was refused by the ' Guardian' on account of its length, and was afterwards published in the ‘Daily News.’ However, in the ‘Guardian’ of Sept. 14, a summary of it is given, in which the following statements are made: (1) that volcanic cones do exist as above described; (2) that, according to Hoffman's ‘Lexicon,’ Rogations were instituted owing to earthquakes and to the irruption of wild beasts into Vienne; (3) that there are no volcanoes near Vienne; (4) that the authors who are supposed to describe volcanic eruptions, only speak of earthquakes and ordinary fires, or perhaps of lightning.
