abby liz itself as a mathematician. Eng
land has one which does similar class
OF work. but does not carry its calcula-
t1ons So far. The British instrument
was invented by. Lord Kelvin. The,
American instrument was contriveds by
r. Terrell, , an employe OF. the United:
States Coast Survey The American
machine &c now in use cost $780,, It
stands about two feet high and is:
eighteen inches across Its half a.

ley and levers. It does wond erful
Things. There is little crank on. the:
lower left hand side, and at simple,
t1rn OF that crank the machine will
give the answer to a. prob lem Involving
Hlnety-one separate calculations, The;
problems it works out are the enor-
mously complicated calculations Of
TIDAL variations. In the year 1903 some,

hour of that particular day of that
particular year there is seven feet Of
tide in the bay. BY referring to- a
chart showing the depth OF. the bay

The calculation by which it is; pos.
sible to predict seven feet Of tide at
that place and time was made by the.
United States governments machine
on May II last in Washington. The
machine ma owned by the British gov.
ernment is the only other one BY
which the calculating could have been
done; but on account of the enormous
volume of such work to be done the
two governments try to divide the ter
rltory. Foreign governments have: fre-
quent1y applied to the United States to-
do some tide foreeasting for harbors
important to their commerce with the
machine Invented by Mr. Terrell, which
the new one is expected to supersede.
They have been quite willing to pay
for such work, but as rule the
coast survey has been unable to COM
ply with such requests, owing to- the
pressure of it's own work. DR.. r. A.
Harris of the Coast Survey devised the.
plans for the new machine now being
constructed. He has taken sugges-
in existence and hopes to produce one
which will combine the good features
Of both. The employment of mechanf-
cal apparatus for doing work usually
performed by the human mind is more
extensively seen in the government
scientific departmen ent than in any other
place in the country. The multiplying
and dividing machine, for example, is
q great saver of time and mental labor
not to mention its absolute accuracy.
The machine declines to make mis-
takes, and if the operator tries to make
seven go into six, will ring a bell in
protest. Practically all the adding in
the governments coast survey work is
done by machines Where the column
contains hree4quarters of million
1gures, as frequently happens in
The computations, the saving in mem
tai effort is very consid derable. NeW

One Potwalloper In England.
. The preliminary register for 1896
showed that there was then only one
spotWal1oper in all England. On see
ing the term for the first time one
might easily imagine that a potWal-
5!oper was a species of ichthy yosaurus
81 some other reptile OF past age. 1t
will be discovered upon inquiry, how
sver, that the term ss potWallope err is
literally one who boils a pot, and was |
applied to voters in certain boroughs
