under one roof, the knowledge these would convey of the machinery,
cultivation, science, literature, and arts practised in the various
parts of the globe would tend to stimulate and advance the mind by
showing that we had not only ourselves to look to, but that in a great
measure we had to depend on others for the many blessings we now enjoy;
and also lead us to see how needful to our prosperity and comfort is a
constant communication with those who can communicate to us that
knowledge which otherwise we could not obtain. Certainly the results
have proved that he was right. Could anything have been more
interesting or instructive to all than a visit to the Great Exhibitions
of 1851 or 1862, or that of Paris in 1867. The public interest is at
once shown when I tell you that 6,039,195 persons visited the latter,
and the receipts in money were £506,100. There, all and every one had
before him at a glance the subject most suited to his taste, with a full
description of the country which produced it. From the largest machine,
the heaviest ordnance, the most brilliant and precious stones, the
finest silks, lace, furniture, carriages, the greatest luxuries for the
table, and, in fact, everything needful for the use of man;--all were
there, and all to be seen and studied by the inquiring mind, or to be
regarded as very wonderful by those who went to the Exhibition as a
sight. Few, I venture to say, ever left these buildings except wiser
than when they entered. It could not fail to strike one, if one only
gave it a moment's reflection, and asked himself, how has all this been
brought about, but that it was the result of the communication of the
minds of certain individuals with those of others, and by a
concentration of the products of various countries to enlighten the
mind as to the vast intelligence of the world at large.

In conclusion, I feel now that I have spoken long enough for any
lecture, though I have not by any means exhausted the subject of
