n fifteen years. Similarly you can take Haydn's Dictionary
of Dates and turn fact after fact into nonsense lines like these which
you cannot lose.

And this ought to be enough to show anybody the whole art. If you look
back across the sands of time and find out that it is that ridiculous
old "Thirty days hath September" which comes to you when you are trying
to think of the length of October--if you can quote your old prosody,

"O datur ambiguis," etc.,

with much more certainty than you can serve up your Horace; if, in fine,
jingles and alliterations, wise and otherwise, have stayed with you,
while solid and serviceable information has faded away, you may be
certain that here is the key to the enigma of memory.

You can apply it yourself in a hundred ways. If you wish to clinch in
your mind the fact that Mr. Love lives at 485 Dearborn Street, what is
more easy than to turn 485 into the word "rifle" and chain the ideas
together, say thus: "Love--happiness--good time--
picnic--forest--wood--rangers--range--rifle range--rifle fine
weapon--costly weapon--dearly bought--Dearborn."

Or if you wish to remember Mr. Bowman's name and you notice he has a
mole on his face which is apt to attract your attention when you next
see him, cement the ideas thus:

"Mole, mark, target, archer, Bowman."

MEMORY RHYMES.

The Months.

Thirty days hath September,
April, June and November;
All the rest have thirty-one,
But February, which has twenty-eight alone.
Except in leap-year; then's the time
When February's days are twenty-nine.

Birthdays.

Monday for health,
Tuesday for wealth,
Wednesday best of all,
Thursday for crosses,
Friday for losses,
Saturday no luck at all.

The lines refer to the days of the week as birthdays. They are, in idea,
the same as the more familiar lines:

Monday's child is fair of face,
Tuesday's child is full of grace;
Wednesday's child is merry and glad,
Thursday's child is sorry and sad;
Friday's child is loving and giving;
Saturday's child must work for its living;
While the child that is born on the Sabbath day
Is blithe and bonny and good and gay.

Short Grammar.

Three little words you often see
Are Articles, a, an, and the.
A Noun's the name of any thing,
As school, or garden, hoop, or swing.
Adjectives tell the kind of noun,
As great, small, pretty, white, or brown.
Instead of Nouns the Pronouns stand--
