fire, which was extinguished in about ten minutes more.

"It was a mighty queer blaze," said Mr. Jackson, "starting at the top
that way. I wonder what caused it?"

"We'll investigate in the morning," decided Tom. "Now, dad, you must get
back to your room." He turned to help his father in, but at that moment
Mr. Swift, who was trying to say something, fell over in a dead faint.

"Quick! Help me carry him into the house!" cried Tom. "Then telephone
for Dr. Gladby, Mr. Jackson."

The physician looked grave when, half an hour later, he examined his
patient.

"Mr. Swift is very much worse," he said in a low voice. "The excitement
of the fire has aggravated his ailment. I would like another doctor to
see him, Tom."

"Another doctor?" Tom's voice showed his alarm.

"Yes, we must have a consultation. I think Dr. Kurtz will be a good one
to call in. I should like his opinion before I decide what course to
take."

"I'll send Eradicate for him at once," said the young inventor, and he
went to give the colored man his instructions, while his heart was
filled with a great fear for his father.
