Origin OF the Word "Magnet."
Thousands of years ago a mineral
having the strange power of attracting
iron was found In the country ancient
" called Magnesia, in Asia Minor. The
name of this country has also given US
the word magnet" This mineral,
which is now called the lodestone (not
loadstone) attracted the attention of
the curious, and it was discovered that
a piece of iron which had been rubbed
with the lodestone acquired the same
power of attracting iron--in other
words, the piece of iron became a mag
net. It was afterward found that such
an iron or artificial magnet could be
used like the lodestone itself to convert
other pieces of iron into magnets by
rubbing. Still more recently mode Of
making magnets by means of cleo
tricity was discoyered-th is, by
wrapping piece Of insulated wire
many times around the bar and then
causing current of electricity to pass
through the wire. The familiar small
toy magnets are simply steel bars
which have been rubbed a few times
on powerful magnets. st Nicholas.
For the Amateur Photographic.
was out last Saturday with my
Photographic chum. or rather one Of
them, and on the way home stopped
at his house for dinner. He explained
that he wished to mix up new devel-
oper in order that 1t should be ready
when he came home to develop his
negatives later in the evening. He
weighed out four ounces of sulphite,
dumped 1t into wide mouthed bottle,
weighed out a like amount Of carbon
ate Of soda and put that in another,
and then poured water into both from
an ordinary pitcher. was astonshed.
Don't you know how much water You
are adding" I asked. "Oh. sure!
When pasted the labels on the bottles
put them on SO that their upper
edges came even with the top of six
teen ounces Of water Now l never
have to use graduate. l put In the
required amounts of the sodas and
then fill UP to the top of the labeis."
think that the hint is a good one.
and am going to do little pasting on
of new labels myself.-EXchange.
The Very First Lightning Rod.
Almost everybody believes that
Franklin was the inventor of the light
ming rod, and in this one particular
nearly everybody is mistaken. Tie
first lightning conductor was not in
vented by the genius who Is said to
have caught the lightning Wild and

by a poor Bohemian monk who lived
at Seuttenberg, who erected his light

1854. The name of this inventive
monk was Prohop Dilwisch. His ap-
paratus was composed of a poe sur-
mounted by an iron rod supporting
twelve curved branches and terminal
ing In as many metallic boxes filed
with iron ore and inclosed with a
wooden boxlike cover This was trav-
ersed by twenty-seyen iron pointed
rods, the bases of which were conN'ct-
ed with the ore boxes. This cn;irc
system of wires WAS united with tie
earth by large chain.
The enemies of Dilwisch, Jealous CT
his success, excited the peasants Of
the neighborhood against him. claiming
that his invention was the cause Of the
dry weather that WAS running their
crops. When the inventor laughed 81
them and refused to remove it they
put him in prison and then destroyed
his work.
