“Soft enough to mold; and then pour in the walls right off quick. You can’t fool round when you’re working with concrete.”
“How can we keep the water fresh in the tub?” asked Ethel Blue of Dorothy.
Dorothy paused, not knowing what to say.
“It would be fun to keep gold fish in it,” she said, “but they would have to have fresh water, wouldn’t they?” She turned appealingly to Mr. Anderson.
“That’s not hard to manage,” he said. “You can put a bit of broomstick between the earth wall and the outer wall of your tub-mold and pour the concrete around it. When the concrete has hardened you pull out the stick and there is a hole. Then you can have a drain dug that will tap that hole on the outside and carry off the water through a few lengths of drain pipe.”
“What’s to prevent the water running off all the time?” Ethel Blue wanted to know.
“Keep a plug in it,” answered the contractor briefly. “And there should be waterproofing stuff mixed with the materials. You have your gardener dig a hole in the garden,” he said, adding, “don’t forget to have plenty of grease.”
“What’s that for?”
“Why do you grease your cake pans?”
“So the cake won’t stick.”
