"Curious it is that every hour of our day is repeated from myriad chimes; and yet how rarely do we attend to the clock striking ! Alas ! how emblematic is this of the way in which we neglect the many signs of time ! How terrible, when we think of what time may achieve, is the manner in which we waste it! At the end of every man's life, at least three-quarters of the mighty element of which that life was composed will be found void—lost—nay, utterly forgotten ! And yet that time, laboured and husbanded, might have built palaces, gathered wealth, and, still greater, made an imperishable name."
