Electricity has superseded steam as
the motive power in rope making at che
Charlestown, Mass, navy yard, the change
having been made last week. 1t Is the
first time electricity has been used for
the purpose, and the experiment will be
watched with interest. The plant is the
only one of the kind owned by the gov
eminent, and nearly all the. rope used in
the service is made there.
The natives in Natal comprise eighty
five tribes. occupying thirty-seven native
locations or preserves. in which white set

the perpetuation of their tribal system,
and in each location they are ruled by
their own chiefs, assisted by indunas or
neatmen- 1NeSe DdtlNe CHlCldlS are, Of

each district and the whole system is
controlled by a secretary of native affairs,

Although America is the home of the
telephone, Berlin led New York in the
number of subscribers until a short time
ago. when this city passed the German
city, and now stands at the head of all
other cities in the world. A telephone ex-
pert who recently visited the European
countries says that New York has also an
ticipated the other large cities in various
fundamental features of telephone supply
The doublewire underground system was
adopted ten years ago in this city, while
in Berlin the subject is only now under
consideration. In London the double-wire
system has been adopted during the last
five years, but the wires are still mainly
overhead. In Paris the wires are below
ground, but the central offices are far be-
hind the times. In Vienna the entire sys-
tenn has been reconstructed within the
last five years, and the American under
ground system is being adopted. New
York also leads other cities in the adop-
ton Of the automatic system of calls, and
in the two years since this was begun
one-half the subscribers in the city have
been supplied; in two years more its in

The rate question has been made more
satisfactory for the people than in other
cities, the message rate having been
adopted by which the cost has been re-
duced as low as $50 a year. This change
from the fiat rate has been the reason for
the large increase in The number of sub
scribers. The result of this system of al
lowing subscribers to pay for what they
get has quadrupled their number in the
last SIX years, and the Borough of Man

combined.
For many years it has been known that
the steam engine did not utilize all its en-
ergies says the New York Press. The or

used hardly more than 5 per cent. of the
value of the fuel burned under its boiler

its steam and returned the warm water IA
