"Will you produce that paper?" he eagerly asked.

"I cannot now," said Rachel; "I gave it to Mr. Philip Held, so that he might find out something more."

Joseph listened with a keen, undisguised interest. After the first feeling of surprise that such an important event had been kept from his knowledge, his confidence in Philip's judgment reassured him.

"Has Mr. Philip Held destroyed that paper?" Mr. Spenham asked.

"He retains it, and will produce it before this court to-morrow," Mr. Pinkerton replied.

"Was there any mark, or label, upon it, which indicated the place where the poison had been procured?"

"Yes," said Rachel Miller.

"State what it was."

"Ziba Linthicum's Drug store, No. 77 Main Street, Magnolia," she replied, as if the label were before her eyes.

"Let Ziba Linthicum be summoned at once!" Mr. Spenham cried.
