Here is a very pretty experiment, sent by F. V. G., Madison, Wisconsin:
"Take an ordinary water-pail. Lay across the top two pieces of stout
wire, about two inches apart. Then lay a lump of ice on the wires. In
about half an hour go and look at it, and you will find that the wires
pass through the middle of the lump of ice, but you can not see how they
came there."

The following tribute to the egg tombola is from Ella W.:

From an egg, shot, and tallow, with care,
A merry tombola I soon did prepare;
I brushed up his locks in a very fine way,
And dressed him in garments of nice sober gray;
And when he was ready all came to admire,
So portly was he that I called him the Squire.

I then laid him down to measure, and see
Whether standing or lying the tallest he'd be;
When he lifted himself with a nod and a bound,
Rocked backward and forward and balanced around.
The giddy tombola! he will not lie down;
It's useless to urge such a funny old clown.
