the front one: the fact that on becom-
ing disconnected from the trolley the
hind boat loses its power and cannot
forge ahead of the boat in front of it.
In electric cable haulage the boats
simply steer by each other and ex-
change motors and go on their way.
A consideration of equal Importance
with the mechanical and electrical
efficiency of the system is its compare
lively low cost. The cost of motors for
canal boat worked by the trolley sys-
TEN would in many cases more than
equal the value of the boat in which
they were placed. With the cable
4 baulage method the oldest and most
dilapidated boat can hire its motor for
the trip or 60 in tow with others, and
require no extra equipment. The cost
of one of these motors is about the same
as that of first-class pair OF mules,
and it has the great recommendation
/ of not "eating its head off, in the
winter time.

appliances are so effective that their
general introduction must result In

of such magnitude as to need the SER
vices of the fire brigade. In one OF
| these alarms the maximum simplicity,
promptitude of action and cheapness
seem to have been reached. 1t has
compartment, which is divided into
two unequal parts by means of flexi-
BILE division. These are filled with two
gases of different expansion, and if the
temperature rises the circuit is closed,
and an alarm is given. This alarm is
said to be extremely responsive to the
slightest change in temperature, and it
can be adjusted accurately to indicate
any degree of heat. 1t is. in fact, SO
sensitive that it is only necessary to
touch the compartment with the palm
of the hand. or to breathe ON it. in
order to set the alarm bell in motion.
1t would certainly seem that with a
device so effective and so little liable to
get out of order as this fire should
have no chance of making any head
way, especially where connection with
system of sprinklers can be estab.

such contrivance in steamers. or sail
ing vessels with infammable cargo.
and it has already been employed to
good purpose in factories for giving
warning in case of the heating of ma
chinery, etc.
Inquiry is often made as to the cost Of
electric cooking. Nelson W. Perry
writing on this subject, gives the most
reliable data at present obtainable.
The cost of an electric lamp is taken at
about | cent per hour. One pint of
water can be brought from so degrees
Fahrenheit to the boiling point at the
cost of two sixteen -candle-power lamps
for one hour; or. By the use of the
equivalent of five lamps it can be made
to boil in twelve minutes; while by the
use of the equivalent of sixteen one
half lamps it can be made to boil in 8
minutes. -Four or five outlets can be
fried by employing the equivalent of
five lamps for twelve minutes. This
includes the time required for heating
the pan. When the electric oven is
used, the equivalent of eighteen
lamps will raise the temperature from
SO degrees Fahrenheit to 1870 degrees
in five minutes, TO 900 degrees in ten
minutes. to 500 degrees in fifteen min
utes and to 437 degrees in twenty min
utes. At this rate electrical cooking is
still more expensive than ordinary
methods. Nevertheless. its use is
daily increasing. Its great advantage
is perfect cleanliness. The electrical
kitchen hardly seems to be Kitchen
at all. There is no heat from the fires,
no smoke and no dirty utensils. As
soon as current can he sold at a figure
which will commend its use for kitchen
purposes to everybody it will become
universal. When that time arrives
cooking will be elevated to an exact
science. and DYSPEPSIA will become but
memory of the past.
A feature which strikes the Ameri-
can traveller in England as peculiar is
the foot-warmer in the railway cars.
In the ordinary car there is no provis-
ion for heating. even in the depth of
winter, and without the ubiquitous
rug and the foot-warmer the passen.
gers shiver in helpless wretchedness
As arrangements are being made for
/ lighting the cars on some of the English
lines by electricity it is proposed to
adopt the same means for heating the
individual foot.warmers. with which
any one can be supplied on request.
The electric foot.warmer is fashioned
out of asbestos cloth, of which there
are three layers. The middle layer is
first stitched backward and forward
with a fine wire. The three layers are
then stictched together. and the whole
is inelosed in fancy cover. A simple
device enables connection to be made
readily with the source of electric sup
ply, and the passenger can modify the
heat at pleasure. This looks to Ameri-
cans like beginning at the wrong end
