GARDEN EXPERIMENTS PERFORMED INDOORS
"The meeting is called to order," began Jay. "To-night, so The Chief says, each fellow has some special thing to talk about. Albert will have an accident with that bottle unless he begins right off, so tune up, Savage."
"This bottle is full of vinegar. I might have brought a lemon or anything else acid. This blue paper is called litmus paper. I got it at the drug store for ten cents. Just look right here, and you will see magic worked. I shall put some vinegar on this piece of paper. See!"
"Turned red as quick as scat!" said Jack.
"Litmus will always turn red when any acid gets on it. I've tried several acids at home. It works every time," went on Albert as if no one else had spoken.
"I cannot see what this has to do with gardens." began Philip.
"Now you keep quiet until I finish. Haven't you fellows heard your fathers talk about sour ground? Well, that means acid soil."
