pies every day. We aid much In the
nineteenth century, but here az the
dawn of the twentieth, we have an on
tirely new field opened up By the ois-
covery 81 radium. and that discovery
the work of a woman. We have Sow
etal new forces-so new that we do not
yet know what they are nor how they
may change the life ana work Of the
world We have radium, helium. thor
ium ana other wonderful things. by
liauld air We have frozen some Of those
rays into a liQuid. and have. as it were,
bottled up the rays OF the sun, aud al
go Of these powerful and uutu now,
altogether unknown forces, Indeed We
are daily more and more surprised at
how little we know, and we cannot but
think that the greatest treasures Of ma
tune are set TO be discovered.
AERIAL NAVIGATION.
How about the air and its nayiga-
ton. Dr. Benz?
THAT Is one OF the most interesting
fields Of scientific investigation, We
know SO little OF the air and It's move
ments that there is much TO discover.

find that the questions of strength and

new elements must be taken into con-

have not been appreciated. To sup

surface In proportion to the weight
must be had than is generally supposed.

the weight increases as the cube OF the

creases only az the square Of the d.

brought this out In an article In at

to make successful flying machines.
