This cheap timepiece is worth as much as a watch that would cost a hundred dollars, for all practical purposes, as far as the time of day or night is concerned.

Since I began to make clocks, the price has gradually been going down.

Suppose the cheap time-keeper had been invented thirty years ago, when folks felt as though they could not have a clock because it cost so much, but must get along with a watch which cost ten or fifteen dollars, what would the good people have thought if they could have had a clock for one dollar, or even less?
This cheap clock is much better adapted to the many log cabins and cheap dwellings in our country than a watch of any kind, and it is not half so costly or difficult to keep in order.

I can think of nothing ever invented that has been so useful to so many.

We do not fully appreciate the value of such things.
