Another business that has had its prln-
cipal growth within the past decade IS
the manufacture and sale Of automatic
musical appliances. particularly mechani-
ca piano players and monographs L IS
only since 1900 that the government bu-
reau has kept the statistics OF this in
dustry separate from the production OF
other musical instruments but IN that
tine the capital invested and the annual
sales have multiplied several times.
Tens OF thousands Of workmen. musical
artists. and salesmen have been given
employment by the demand that has

special training 20 enjoy music IN their
homes. Probably $50.Oo0.000 win be ex-
pended during the present year upon the
various forms OF automatic music While
the spread In popularity OF the automatic
piano player Is responsible also for a
great Increase in the sales OF pianos
The manufacture OF cement IS not a
new industry. strictly speaking. but the
growth in concrete construction has ad-
vanced by such leaps and bounds within
the past few years that X is entitled 70
be included within this category The
use OF concrete in the building of fac
tories. bridges. and dwellings is respon-
sl0le for a large share OF the growth
which doubled the consumption Of ce-
ment between 1901 and 1913 and again be-
tween 1893 and 1915.
While the panic Of 1907 and the conse-
Quent depression In the building trade
caused a temporary halt In this rapid
advancement. the money value OF the
product amounts 70 over 100000 a year.
and the expenditure represented by the
building operations IN which Il IS en-
ployed Is two or three times this SIM
With the perfection OF the method devised
BY Edison for pouring houses Of con

growth Of this industry bids fair 70 be
still more rapid.
Artificial Ice Profitable.
Among other more prosaic lines OF
manufacture which have experienced the
most remarkable growth within the past
decade are the beet-sugar industry and
the manufacture OF artificial ice The
capital invested n both these industries
has advanced from q million and a half
dollars IN 1850 10 more than S125.o00.0o0 al
the present time. while the annual value
OF their product has grown in the same
period from three-Quarters OF q million
dollars annually 10 nearly s., ,0oo COO az the
present time.
An Industry that has not yet advanced
even to the infant stage. but which from

70 duplicate within the next ten years

bile during the past decade. IS the pro-
duCtiOn OF machines FOR aerial flight
Already several companies have been or
ganized for the building OF aerOplanes
and dirigible balloons, and an aerial
transportation line recently chartered IN
Massachusetts promises 20 begin opera

1910. Even IN the present Undeveloped
state OF aerial navigation hundreds OF
| thousands OF dollars has been invested
/ by governments and individual expert
menters. He would be a bold prophet
who should predict that by 1873 a quar-
ter OF a billion dollars would be devoted
every year 20 the navigation OF the air,
Yet this would be no more remarkable
than the showing that has already been
made in other new fel6s OF activity.
At any rate. the fact that half a dozen
! infant industries involving a yearly out
