not had wind enough of
daytimes lately to grind a handful," he said. "I can't invite you
inside, young ladies, because when they set up this mill for me they
made the door, as you see, right behind the sails. When the arms are in
motion I am shut in till the grist is ground; or I stop the sails with
this lever just inside the door--d'ye see?"

As the girls went back toward the house the arms began turning with a
groaning sound. The wind became fresher. Round and round the long arms
turned, while the canvas bellied like the sails on a boat.

Louder and louder grew the hum of the mill. The miller threw in the
clutch and the stones began to grind. They heard the corn poured into
the hopper, and then the shriek of the kernels as they were ground
between the stones. The whole building began to shake.

"What a ponderous thing it is!" exclaimed Frank. "And see! there's a
tiny window in the roof facing the lake. I imagine you could see clear
to Meade's Forge from that window."

"Farther than that, my dear--much farther," said the farmer's wife,

young cooks were on their mettle, and did the best they could. If the
hot biscuits were not quite so flaky as their mothers' own cooks made
them at home, and some of the poached eggs broke in the poacher, and the
broiled bacon got afire several time and "fussed them all up," as Mina
said, the general opinion of the occupants of Green Knoll Camp was that
"there was no kick coming"--of course, expressed thus by the slangy
Frank Cameron.

Grace _would_ dawdle over the dishwashing, and Percy was a good
second. Therefore, those two still had work on their hands when Bess
sighted a motor boat coming swiftly toward their camp from the direction
of Gannet Island.

"Now somebody's going to butt in and bother us," declared Bess. "It
can't be the Busters, I s'pose?"

"That's exactly who it is!" cried Wyn, delightedly. "That's the _Happy
Day_. D
