He swung his grindstone from his back and set it on the ground.

“Will you please sharpen my scissors?” asked Mother.

The scissors-grinder took the scissors in his hand.

Then “Whir-r-r, whir-r-r, whir-r-r,” went the grindstone. Sparks flew from the whirring stone.

Bobby and Betty stepped back. They were afraid of the grindstone.

“Any knives to grind?” asked the scissors-man when the scissors were ground.

“Yes,” answered Mother. “I wish you would grind this knife.”

Again the wheel went, “Whir-r-r, whir-r-r, whir-r-r.”

Again sparks flew from the grindstone.
