"When I grow up," said Ethel Blue, "I'm going to have a large microscope
like the one they have in the biology class in the high school. Helen

of rooms. Each room was a cell, Helen said."

"I was telling the girls about that time when I looked through the high
school microscope," answered Ethel Blue.

A single cell is all there is to the lowest animal or vegetable."
