be a dollar an' a half a month interest." He stopped, satisfied
that he had proved his contention. Then his face quickened with a
fresh thought. "Hold on! That ain't all. That'd be the interest
on the furniture for four rooms. Divide by four. What's a dollar
an' a half divided by four?"

"Four into fifteen, three times and three to carry," Saxon
recited glibly. "Four into thirty is seven, twenty-eight, two to
carry; and two-fourths is one-half. There you are."

"Gee! You're the real bear at figures." He hesitated. "I didn't
follow you. How much did you say it was?"

"Thirty-seven and a half cents."

"Ah, ha! Now we'll see how much I've ben gouged for my one room.
Ten dollars a month for four rooms is two an' a half for one. Add
thirty-seven an' a half cents interest on furniture, an' that
makes two dollars an' eighty-seven an' a half cents. Subtract
from six dollars. . . ."

"Three dollars and twelve and a half cents," she supplied
quickly.

"There we are! Three dollars an' twelve an' a half cents I'm
jiggered out of on the room I'm rentin'. Say! Bein' married is
like savin' money, ain't it?"

"But furniture wears out, Billy."
