"They're fine, Mr. White. This one's name is Spot. She's my favorite; she's a three-year-old and gives twenty quarts of milk each day. That's better than any of the others, although two of them come pretty close to her. When we get the new barn and can, regulate their feeding, they'll all do much better."

"Why, do you know how much milk each cow gives?" inquired Mrs. White, surprised.

"Certainly," said Bob, "we not only know, but we set down every day how much we get, so we can keep a record. If you'll come down to the dairy house, I'll show you how it's done. Of course, we don't measure each cow's milk separately every day, or weigh their cream every day, but every time I milk, I keep the milk of one cow in a separate pail, so it may be weighed. For instance, I'm taking note of Spot's yield to-day."

"This is very interesting, Bob," said Mrs. White. "I didn't think you went into farming so scientifically."

"They don't on some farms," replied Bob, "but Aunt Bettie and I keep books here on Brookside Farm. We want to find out what pays the best."

"That's right," said the banker, "working and figuring go hand in hand, and if you keep that up Brookside Farm will soon be paying a good profit."

"Will you let me see your books after supper, Bob?" he asked. "Your
Aunt Bettie has invited us all to stay and have supper with you."

"Yes," said Bob. "I'll be glad to."

"Did that one cow give that much milk?" asked the banker's wife in astonishment, as she saw the huge pail Bob had gotten from Spot.

"Yes," said Bob proudly.
