"No. I haven't got that far yet."
"Can you tell me if you are working on some new thing?"
"I don't mind." Bauer got up and pulled a piece of paper towards him and began to sketch something. Helen got up and went to the end of the table where she could see better.
"There, Miss Douglas. This is my idea for a chicken raiser."
"An incubator?"
"Yes. You see this dome is glass, very much like those domes the glass blowers make to put over their glass ships and flowers. The bottom here is wood. The eggs are placed on it in even rows. Here is a hole in the bottom through which the electric lamp is put. A thermostat will regulate the temperature to a fraction of any degree. And—that is all there is to it except to try it on the eggs to see if they will really hatch out."
"I don't see how they could help it!" said Helen enthusiastically.
"I don't either. There's only one thing I can see that is essential."
"What is that?" Helen asked eagerly.
"The eggs will have to be good," said Bauer solemnly.
