them to the sides of the arrow,
about an inch from the notch, at equal distances apart. There
should always be three feathers.

It is a good plan to fasten the feathers to the arrow with pins until
the glue is perfectly dry, when they can be carefully removed.

SAN FRANCISCO, CALIFORNIA.

I have a pet now, a lovely little dog, with long curly hair and
large bright eyes. He is snowy white all over, and his name is
Mischief. I am going to have his picture taken some time. He looks
just like a bundle of cotton, with three black spots shining
through. Those are his eyes and nose.

The tree represented in the illustration of the beetles in YOUNG
PEOPLE No. 38 is just like the California buckeye-tree. The
blossoms are exactly the same.

I am very much interested in the directions for making salt and
fresh water aquariums. When I was in Monterey I might have
collected lots of sea-anemones, snails, and pink and white
star-fish, but I did not think of it. One of the gentlemen at the
hotel went fishing with a net, and caught a little baby
cuttle-fish, or devil-fish, as it is commonly called. It had seven
or eight long legs, all lined with little suckers, like buttons.
It was a dreadful ugly-looking thing. It must have been very
young, for it was only ten or eleven inches long. The gentleman
was going to keep it for a curiosity, and until he could get
something better he put it in a pan of salt-water; but he forgot
to cover the pan, and in the night the fish crawled out on to the
floor, and died.

I have exchanged Farallon Island eggs and leaves and specimens of
trees with a good many children since my letter was printed.

Is there any difference between postage stamps and postmarks? I
don't believe I know what postmarks are.

IDA BELLE DISERENS.

A postmark is the stamp put on the outside of a letter at the office
where it is posted. It certainly is not of much value in itself, but if
a collection is neatly pasted in a book, States and countries being
arranged together, counties being written under towns in the United
States, and a note made of any manufactories or natural productions for
which the town is celebrated, such a collection may become an
interesting gazetteer, and valuable as a book of reference.
