a little known group of fungi is the
Laboulbeniaceae, which grow only on
insects and almost exclusively on
beetles and nies. Though first de-
scribed in 1853, according to Dr. Ro-
land Thaxter, hardly more than
dozen species hid been distinguished
In 1884. while not less than 1850 species
belonging to 30 genera are now known.
The study OF these fungi, which up
pear like minute hairs seldom more
than n fiftleth OF an inch long. seems
to have been confined almost wholly
to American botanists, only 10 Eu-
ropean species having yet been found.

Medium weight pneumatic tires in
flated to pressure of 80 lbs per square
inch have been shown by late tests to
be just able to Keep the fellows off the
road with a weight Of $50 lbs in the
saddle. The efficiency VI the machine
under these circumstances was about
81 per cent. with a pressure of 40 lbs
the efficiency rose to "a per cent, and
at 70 lbs 1t was about 81 per cent

The double stars thus far discovered,
says NJ. Camille Flammarlon, number
about 10000, but the orbits OF only IS
have been calculated. These orbits
vary, greatly in length, the period of
revolution ranging from a little more
| than five of our years to nearly two
centuries. a star of the constellation
Andromeda, however. is resolved by
powerful telescopes into three suns, one
OF which turns around another in 81
| yeras, and these two revolve about the
| thtrd in II period which--if continued
uniformly at the rate observed since
| the first discovery of the third sun in
| l1I1-must extend to 800 centuries! This
| triple star is visible to the naked eye,
| becoming double in small telescope.
! IL is a mistake to regard double stars
as separate class of heavenly bodies,
for they are of various kinds. some con-
slsting of two similar suns, while in
others an enormous sun is attended by
much smaller star, as in the case of
Sirius, and in still others we have a
sun with a dark star. .yhich makes its
presence known by eclipslng its COM

| ms variable star. one of the most
remarkable characteristics of double
stars is the wonderful coluiing OF some
| OF them. The star in Andromeda, for
| instance, contains an orange q green
| and blue star of beauty that defies
the art of the painter to reproduce.
