"Hurrying o'er the illimitable waste, With the fleet waters of a drowning world In chase of him: whereat I [meaning the poet] waked in terror, And saw the sea before me, and the book In which I had been reading at my side."[110] [110] On comparing these quotations with the original passages in _The Prelude_, one finds that De Quincey, quoting from memory, is not exact to the text in any of them save the last.--M. The sketch I have here given of this sublime dream sufficiently attests the interest which Wordsworth took in the mathematic studies of the place, and the exalted privilege which he ascribed to them of co-eternity with "the vision and the faculty divine" of the poet--the destiny common to both, of an endless triumph over the ruins of nature and of time. Meantime, he himself travelled no farther in these studies than through the six elementary books usually selected from the fifteen of Euclid. Whatever might be the interests of his speculative understanding, whatever his admiration, practically he devoted himself to the more agitating interests of man, social and political, just then commencing that vast career of revolution which has never since been still or stationary; interests which in his mind alternated, nevertheless, with another and different interest, in the grander forms of external nature, as found amongst mountains and forests. In obedience to this latter passion it was--for a passion it had become--that during one of his long Cambridge vacations, stretching from June to November, he went over to Switzerland and Savoy, for a pedestrian excursion amongst the Alps; taking with him for his travelling companion a certain Mr. J----, of whom (excepting that he is once apostrophized in a sonnet, written at Calais in the year 1802) I never happened to hear him speak: whence I presume to infer that Mr. J---- owed this flattering distinction, not so much to any intellectual graces of his society, as, perhaps, to his powers of administering "punishment" (in the language of the "fancy") to restive and mutinous landlords; for such were abroad in those days,--people who presented huge reckonings with one hand, and with the other a huge cudgel, by way of opening the traveller's eyes to the propriety of settling them without demur, and without discount. I do not positively know this to have been the case; but I have heard Wordsworth speak of the ruffian landlords who played upon his youth in the Grisons; and, however well qualified to fight his own battles, he might find, amongst such savage mountaineers, two combatants better than one.
