ough this the water is
introduced. For this purpose a small funnel will be found convenient.

When all is complete, the boiler may be filled about half full, and set
on a hot stove. When the water boils, the steam will emerge through the
spout, and propel the wheel. As the steam constantly escapes, no
explosion need be apprehended. To remove all possibility of creating too
much pressure, place the cork in the neck very lightly, so that it will
pop out if more steam is generated than can escape through the spout.
Then the miniature steam-engine and boiler may be regarded as harmless
as a tea-kettle. As the quantity of steam that can be produced is very
limited, care must be taken that there be no leaks, that the mouth of
the spout be quite small, and that the current of steam be discharged
accurately into the buckets. The bearings of the shaft should be oiled,
and everything arranged so that there will be the least possible
friction. Then the wheel may be expected to spin very rapidly.

WHO WILL TELL?

As Benny Mallow hid himself in a barn in the yard into which he had
jumped, he had only one distinct thought in his mind: he wished that the
Italian had never come to Laketon at all--never come to the United
States, in fact. He wished that the Italians had never heard of such a
place as America: if one of the race had to discover it, he need not
have gone and let his fellow-countrymen know all about it, so that they
should come over with organs and monkeys, and get boys into
trouble--boys that weren't doing a thing to that organ-grinder when he
threw a stick at them. What made the fellow go into the school yard,
anyway? No one asked him to come. Now there would be a fuss made, of
course; and if there was anything that Benny hated more than all other
things, it was a fuss.

But what if the organ-grinder should really prove to be dead? Oh! that
would be too dreadful; all the boys would have to be hanged, to be sure
of punishing the murderer, just as the whole class was sometimes kept in
for an hour because something wrong had been done, and no one would tell
who did it.

Benny could not bear the thought of so dreadful a termination to his
life, for he knew of a great deal worth living for; besides, his mother
would need his help as soon as he grew old enough to e
