perfected the many powerful and
beautiful instruments now required for taking observations, and these,
when compared with the instruments in use in bypast times, are excellent
evidences of modern progress in this direction. Our wonder is excited
when we look at the instruments formerly in use; that so much was done
through them, and the advance made by art in the perfection of those now
adopted, show us again that knowledge is power.

The navigator, by a combination of astronomy and seamanship, is enabled
to plough the great deep, and at all times by mathematical calculation
to discover the exact position of his ship. What, however, would he be
without the aid of art? The compass, the sextant, or quadrant, &c., are
the means which enable him to attain these grand results, and to bring
his ship to the desired haven. The use of these is knowledge, and this
knowledge is power.

Alike with all other things which science and art have called into use,
knowledge is power, and this power was given by the Almighty, as I said
at the beginning of this lecture, to enable man to fathom the works of
creation. Let us then so live that we may ever admire the results of the
labours of science and of art, and at the same time ever remember Him
who has given us the power to discover and use them for our
benefit,--thanking God, who first made all things and pronounced them
very good, for His great mercy toward us.

_A PENNY'S WORTH_;

OR,

"TAKE CARE OF THE PENCE, AND THE POUNDS WILL TAKE CARE OF THEMSELVES."

A penny seems a small sum to talk about, and with many, I am sorry to
say, is looked upon as so insignificant as to be considered almost
worthless; but I hope, before I have done, to show you something of the
great value of even a penny, and of the effects and products we have
been enabled to produce and dispose of with a reasonable profit at the
cost of one penny. A much smaller sum than this was looked upon and
regarded as of inestimable value by our blessed Saviour, when He saw the
rich men and the widow casting their offerings into the treasury, for He
said: "All these have of their abundance cast in unto the offerings of
God: but she of her penury hath cast in all the living that she had."

Now what did this widow cast in? Two mites, which make one farthing.
Though this took place more than eighteen hundred years ago, it shows to
us even now the great value of small things wh
