So says Uncle Sam. And he backs up
this assertion with the purchase every
year of a railroad car. fitted up to carry
his discoveries broadcast
Some six or seven cars he owns now
and an order has just been placed for
another. Verify. according to the ma
tional relative. the proper thing to do
when one desires his remarks to have
hearing is not to hire a hail. but to
buy q railroad car.
Education on wheels seems to at
tract the interest and the plaudits OF
the muItitudes The travelling show has
never needed to make a strong outside
bid for favor; II carries its success with
It: people welcome it inevitably. Uncle
Sam remembered this.
Also he remembered that he has
tremendous family of nieces and neph
inherent curiosity about show from
'furrin parts with their need for en-
lightenment? The problem was simple
just a matter of inoculating little
seriousness into the show or putting
some sure enough" tonic into the mix

oculating a little novelty into the DEM

Hence the federal special" which.

and soon to be added. from the bureau
of chemistry.
The car from the food research labor

ing the appalling s5o,o00.000 yearly egg
waste. Surely. any laboratory that
goes out to save such sum deserves

The wool-exhibit car of the bureau of
animal industry shows ranchmen how
TO prepare their wool for market SO as
to increase their profits.
The bureau of fisheries car carries
live fishes from the Pacific. from the
Atlantic and from the great lakes to
stock the individual and public plants
of those who are following the new
pursuit. fish raising
The bureau of standards car is de-
signed to go about the country testing
track scales on railways and the weigh

such establishments where commodi-
ties. destined for the general public. are
weighed in bulk. to see IL the measures
conform to standard.

The newest car. which really is not

will operate in connection with the

This car Is going to save Uncle Sans
complaints were made about any prod

Samples of the products could not be
products are perishable: they decay en-

journey would. therefore. not be fair
one.
And when the chemists arrived. they
set about renting and equipping quar-
tiers for their experiments. All this
meant expense-much OF 1t. needless
expense; and the quarters were not
always satisfactory. All around. 1t
was bad job
But wsth the new car all this will
be changed. The laboratory will be
perfect and always intact. 1t may work
