your crop. Put a little lime water on the litmus which the acid has
turned red."

Albert did this and the boys watched interestedly to see the effect.
"Back again," sang out Jack as the red litmus changed to blue.

"Now from this you see a way to overcome the acid conditions of Albert's
piece of land, if it proves to be acid."

"I see," said Jack, "lime it."

"Exactly! Now see, Albert, if the paper has changed colour."

"My, I should say it had!" and Albert held up the piece of litmus paper,
now quite red from its contact with the soil.

"Well, Albert, it is pretty plain to see what you have to do. Did you
find out the amount of lime to use?"

"In the book I read it said for clay soils 400-2000 pounds per acre."

"I should say," said The Chief, "for that special piece of land use
about 20 bushels to the acre."

"How many pounds of lime," asked Jack, "to the bushel?"

"I can answer," grandly went on Albert, "there are 70 pounds to the
bushel. So that makes 1400 pounds."

"Quite a proposition!" said Jay.
