EUCALYPTUS TREES. nL ly 
carried before us the torchof scientific inquiry into 
the dark recesses of mystery, and shed a flood of light 
on perhaps long-concealed magnificence and beauty. 
The youth, aroused to the sublime feeling of wishing 
at least to follow great men in independent research- 
es, may be animated if in a hall like this each divis- 
ion were ornamented with the portraits of the fore- 
most of those discoverers who through ages advanced 
knowedge to the standard of the present day. _ 
** Deeds of great men all remind us 
We can make our lives sublime, Am. w 
And departing leave behind us 
Footprints on the sands of time. : 
“‘ Though oft depressed and lonely, 
Our fears are laid aside, i 
If we remember only ‘ 
Such also lived and died, ;, % 
*¢Learn from the grand old masters, t 
Or from the bard sublime, “Nene aa 
Whose distant footsteps echo ; 
Through the corridor of time.’’

Discovery proceeds step by step. Commenced by 
original thinkers, enlarged by sedulous experimenters, 
fostered by the thoughtful portion of the community, 
and by any administration of high views, it is util- 
ized by well-directed enterprise, and marches onward 
steadily in its progress. Guttenberg and his collabo- 
rators gave us the printing art, which has done more 
to enlighten the world than all other mechanisms 
taken together; and though four centuries have alter- 
ed much in the speed and cost of producing prints, 
they haye not materially changed the forms of this 
glorious art, as the beautifully-decorated pages of the 
earliest printed Bibles testify. Thus we have reason 
to be yet daily grateful for this invaluable gain from 
the genius of days long passed,
