"True! true!" said the inventor, sadly. "It was when our troubles first began, and I found it necessary to economize. But I did very wrong to take you from school at that time."

"You forget, pa," replied his daughter, in a sweet, chiding voice. "You wanted me to go on with my studies, but I said that you must save the tuition money, and let me learn to keep house. Don't you remember, pa?"

"Yes, child; I remember. And I was selfish enough to allow you to make the sacrifice. But you shall have schooling to your heart's content now, whether you will or not. I agree with our dear friend, that no time should be lost in resuming your education. I shall insist upon setting apart two hundred dollars for that purpose. Enough money will still be left to perfect my invention; and that, too, within a month, notwithstanding" (he added, playfully) "Mr. Wilkeson's discouraging remarks a moment ago."

"And I shall insist upon not taking the money, pa," said Pet, laughing, but shaking her head, and patting her feet on the floor in the most decisive manner.

"And I shall insist on furnishing the money," said Marcus Wilkeson, folding his arms, and looking very much in earnest. "Let us see who can be obstinate the longest."

"Then I shall insist on your taking another fifth interest in the invention. Upon that point I am immovable." Mr. Minford folded his arms likewise, to imply that nothing could shake his granitic determination.

"Ah, now I see some prospect of a friendly arrangement. I will pay five hundred dollars for another fifth, and esteem it a good bargain, provided your daughter consents to let one half of it be spent on her education. What do you say to that, Pet?"

"That I thank you very much for your kind offer," said the young girl, whose eyes sparkled with gratitude; "but I must not accept it. Pa will need all the money he can get to finish his work. I know it."

Marcus and the father exchanged pleasant looks, and the former said, with an ill-assumed sternness:

"Then I don't advance another cent to him. I have named my conditions, and they must be accepted. You have no idea, Pet, what a tremendously obstinate fellow I am when I'm roused."
