We have all noticed the curious fact of the extreme apparent inequalities of time, though it is, in its essence, of all things the most uniform. Periods of pain or acute discomfort seem unnaturally long, but this lengthening of time is fortunately not true of all the melancholy scenes of life, nor is it peculiar to things that are painful. An invalid life with its almost unbroken monotony, and with the large measure of torpor that often accompanies it, usually flies very quickly, and most persons must have observed how the first week of travel, or of some other great change of habits and pursuits, though often attended with keen enjoyment, appears disproportionately long. Routine shortens and variety lengthens time, and it is therefore in the power of men to do something to regulate its pace. A life with many landmarks, a life which is much subdivided when those subdivisions are not of the same kind, and when new and diverse interests, impressions, and labours follow each other in swift and distinct succession, seems the most long, and youth, with its keen susceptibility to impressions, appears to move much more slowly than apathetic old age. How almost immeasurably long to a young child seems the period from birthday to birthday! How long to the schoolboy seems the interval between vacation and vacation! How rapid as we go on in life becomes the awful beat of each recurring year! When the feeling of novelty has grown rare, and when interests have lost their edge, time glides by with an ever-increasing celerity. Campbell has justly noticed as a beneficent provision of nature that it is in the period of life when enjoyments are fewest, and infirmities most numerous, that the march of time seems most rapid. The more we live, more brief appear Our life's succeeding stages, A day to childhood seems a year, And years like passing ages. * * * * * When Joys have lost their bloom and breath, And life itself is vapid, Why as we reach the Falls of death Feel we its tide more rapid? * * * * * Heaven gives our years of fading strength Indemnifying fleetness; And those of youth a seeming length Proportioned to their sweetness.
