"I see clearly that the temperature of this castle is going to be just right," exclaimed Roger.
"After the air leaves the spray chamber it goes over some plates that take all the moisture out of it, and then the fan forces it through the pipes that go into every room."
"Are those the little gratings I noticed in all the rooms the other day?" asked Ethel Blue.
"Those are the ventilators. Don't you think we've made everything very compact here? All these pipes take up very little room."
"Mighty little!" commended Roger. "And they're all open so you can get at them without any trouble."
"Here's a scheme Patrick suggested," laughed Dorothy, pointing upward to what looked like a concrete shelf with an upturned border almost at the top of the cellar wall.
"That shelf is directly underneath the seat beside the fireplace in the drawing room. Patrick plans to save himself the trouble of carrying up the logs by piling them on this shelf down here. Then he lifts the cover of the seat upstairs and all he has to do is to take out his wood and make his fire!"
"That certainly is a cracker-jack labor saving device! Good for Patrick!"
"He's especially tickled with the vacuum cleaner run by this same little motor. You ought to hear him talk about it."
"What are these cupboards for?" asked Helen who had been exploring.
"That one with the glass doors is for preserves, and the place in the other corner that has a fence for its two inside walls is a place for cleaning silver and shoes and lamps and brasses. See--there are cupboards along the inside of the fence. They hold all the cleaning materials, and the cleaner can sit in a swing chair in the middle and use a different part of the concrete shelf against the two cellar walls for boots or fire-irons or knives and forks or lamps. At one end is a sink so he can have what water he needs for his work and he can wash his hands when he turns from one kind of cleaning to another."
"And he isn't all smothered up in a small room. Who thought of that?"
"Patrick and I worked that out together. Patrick has lots of ingenuity."
"I should say you had, too!" exclaimed Della, admiringly.
"Here's where Dorothy does her carpentering," cried James.
"I may move that bench up in the attic later," explained Dorothy, "but I thought I'd leave it here until the house was done, because there are apt to be little things to be hammered and nailed for some time, I suppose."
