"What for, mamma?"

"I want to buy some braid to bind Dan's vest. He will want to wear it in the morning."

"May I go with you, mamma?"

"No, my child. You can be reading your picture-book till I come back. I won't be long."

So Mrs. Mordaunt put on her street dress, and left the house in the direction of Eighth avenue, where there was a cheap store at which she often traded.

No sooner did Hartley see her leave the house, as he could readily do, for the night was light, than he hurried to Union Square, scarcely five minutes distant, and hailed a cab-driver.

"Do you want a job, my man?" he asked.

"Yes, sir."

"Can you hold your tongue?"

"Yes, sir, if necessary."
