Another observation in the same line of reflection also must often strike one:--for what very different qualities than those for which we were first passionate do we come afterwards to value our old enthusiasms. In the day of their bloom it was the thing itself, the craze, the study, for its own sake; now it is the discipline, or any broad human culture, in which they may have been influential. The boy chases the butterfly, and thinks not of the wood and the blue heaven; but those only does the man remember, for the mark of their beauty upon him, so unconsciously impressed, for the health of their power and sweetness still living in his blood--for these does that chase seem alone of worth, when the dusty entomological relic thereof is in limbo. And so that long and costly shelf, groaning beneath the weight of Grose and Dugdale, and many a mighty slab of topographical prose; those pilgrimages to remote parish churches, with all their attendant ardours of careful 'rubbings'; those notebooks, filled with patient data; those long letters to brother antiquaries--of sixteen; even that famous Exshire Tour itself, which was to have rivalled Pennant's own--what remains to show where this old passion stood, with all the clustering foliage of a dream; what but that quaint cadence I spoke of, and an anecdote or two which seemed but of little import then, with such breathless business afoot as an old font or a Roman road? One particular Roman road, I know, is but remembered now, because, in the rich twilight of an old June evening, it led up the gorsy stretches of Lancashire 'Heights' to a solemn plateau, wide and solitary as Salisbury Plain, from the dark border of which, a warm human note against the lonely infinite of heath and sky, beamed the little whitewashed 'Traveller's Rest,' its yellow light, growing stronger as the dusk deepened, meeting the eye with a sense of companionship becoming a vague need just then.
