which way she was to
turn next.

If I had followed the strict line of duty, I suppose I should have turned
my steps in the direction of Mr. Keller's house. I followed my instincts
instead, and offered my services to the young lady. Blame the laws of
Nature and the attraction between the sexes. Don't blame me.

"I heard you asking for the post-office," I said. "Will you allow me to
show you the way?"

She looked at me, and hesitated. I felt that I was paying the double
penalty of being a young man, and of being perhaps a little too eager as
well.

"Forgive me for venturing to speak to you," I pleaded. "It is not very
pleasant for a young lady to find herself alone in such a crowded place
as this. I only ask permission to make myself of some trifling use to
you."

She looked at me again, and altered her first opinion.

"You are very kind, sir; I will thankfully accept your assistance."

"May I offer you my arm?"

She declined this proposal--with perfect amiability, however. "Thank you,
sir, I will follow you, if you please."

I pushed my way through the crowd, with the charming stranger close at my

purse, and the letter is so important!"

It occurred to me immediately that she had had her pocket picked by some
thief in the crowd. The clerk thought so too. He looked at the clock.
"You must be quick about it if you return for the letter," he said, "the
office closes in ten minutes."

She clasped her hands in despair. "It's more than ten minutes' walk," she
said, "before I can get home."

I immediately offered to lend her the money. "It is such a very small
sum," I reminded her, "that it would be absurd to consider yourself under
any obligation to me."

Between her eagerness to get possession of the letter, and her doubt of
the propriety of accepting my offer, she looked sadly embarrassed, poor
soul.

"You are very good to me," she said confusedly; "but I am afraid it might
not be quite right in me to borrow money of a s
