that is brushed by sweepers into the
grooves of the rails and is there COM
pacted by the wheels of the cars. The
apparatus is carried on special car,
fitted with two Is horse power motors.
and consists of brushes of steel on each
side for loosening the dirt from the
rails, with a vacuum pump-driven by
an electric motor-that automatically re-
moves the dirt and deposits it in a box
in the bottom of the car. Dust in dry
weather is avoided by sprinkler, with
two water tanks of 925 gallons each.
An automatic signal tells the motorman
when the dirt box is full, and he then
stops the pump, raises the brushes, and
takes his load to a dumping place. The
car is made to work at any speed up to
II miles an hour. 1t uses little power,
requires but one man, and readily
cleans As miles of track day, removing
cubic yard of dirt or less per mile.
= To explain comets tails, DR.. L.
Zehnder, German astronomer extends
theory he first suggested quarter of a
century ago. AS the swarm of meteo-
rites making up the comet approaches
the sun, those nearer the sun begin to
give out gases and vapors, which form
atmospheres about single meteorites or
groups of several, and the suns rays are
concentrated by these atmospheres to
foci at different distances behind If a
meteorite is in the focus, it may be rem
dered visible or heated enough to burn
any hydrocarbons it may contain. In
this way the tail visible lengthens out
as the sun is approached, and is always
on the side away from the sun.
The pain of rheumatism, as is we'll
known, is lessened by hot air, and at a
German animal hospital the hot air
treatment has been applied by means of
an electric blower originally designed as
hair drier. Dogs with rheumatism,
horses with lame shoulders and other
suffering animals we're relieved by this
new pain-soother.
Whatever may be the effect of sour
milk in retarding old age, it seems to
have certain advantages as a diet, and
is quite certainly beneficial in some
cases. With advancing years, the
microbes always living in the intestines
are found to change, becoming more of
kind producing putrefactive decompo-
siton. The studies of Metchnkotf
suggested that old age may be due to
selt-poisoning by the products of this
decomposition, and his experiments
were thought to prove that Tactic acid is
the most effective agent for opposing the
development of the harmful forms.
Bulgarian sour milk was chosen for in
Producing the proper organi SINS into the
intestines, as it contains the most
powerfully acting of various microbes
yielding Tactic acid. Sour milk is much
used not only in Bulgaria, but in Tur-
key, Russia, Siberia, India and other
countries, and Metchnikoff found
confirmation of his theory in the fact that
some persons whose diet included little
else lived to an advanced age. Prof. T.
r. Hewlett states that somewhat vary
ing methods are adopted for preparing
natural and artificial sour mlks. The
milk must first be sterilized by boiling,
and the proper Tactic ferments are then in
troduced either by adding little sour

pure cultures. Care must be taken to
prevent contamination with undesirable
organisms. Sour milk is not to be
taken indiScriminately, as it sometimes
dlsagrees, but it seems to have proven
of undoubted benefit in some old age
troubles, including anaemia, flatulent
dyspepsia, headache, some constipation
and diarrhoea, and rheumatism.
In seeking day light effects with arti-
fetal lluminants, H. Z. Ives, of the
Washington Bureau Of Standards, eX-
perimented with combinations of mer-
curry vapor lamps with incandescent gas
lamps, with carbon tilament electric
lamps, and with metal filament lamps.
The mercury vapor and metal filament
lamps gave the best results. The lamps
we're arranged in clusters, the metal
filaments being in somewhat greater
number and were so placed as to diff
fuse the light, The effect was very
pleasing, the light being soft and
steady, with no glare or deep shadows
