"I say, Chief, don't you think some of us might go up to the city and help Philip make the cement pond?" asked Albert eagerly.

"We might," murmured Jay, "if we get invited."

"Boys, it's late. We know a little of what our stunts are to be. Next week each of you bring about fifty seeds of each kind you intend to plant. Be able to tell just how these seeds should be planted. Also have the dimensions of your plots. Jack will bring some soft wood along, too.

And Philip, find out, if possible just how much money you can have for shrubs. Now on with your coats! Out of my house in two seconds!"

"No food to-night is a sad blow, Chief," said Albert pretending to weep as he opened the outside door.

"This blow is sadder," replied Jack, playfully shoving Albert clean out of the door.

THE GIRLS' SECRET

A very timid little knock roused The Chief from his study of Jack's coldframe plans. The outer door gently opened and three little girls entered and advanced to where the man sat. One, the smallest of the three, was thrust forward as spokesman. Gathering herself together she began with a rush. She thrust a letter into The Chief's hands.

"This is the boys' horrid letter. We don't care particularly about belonging to a boys' club. We wouldn't now, any way. But we'd like to show those boys a thing or two and we thought perhaps you would help us.

Will you?"

"Sit down, and we will work out a little plot together. But first tell me your names. I like to know the names of people with whom I plot."

The girls came close to the man. The spokesman did the introducing. "I am Delia, Peter's sister, and just as smart as he is. This," pointing to a quiet, pleasant-faced girl, "is Ethel. And the other is Jack's sister, Elizabeth."

"How many more girls belong to this company?"

"They are all outside waiting, I'll call them in if you say so. They are behind the lilac bushes. You see we were afraid some of the boys might come to see you, so we hid. For we don't wish them to know about this at all. I'll call the girls in now." So Delia ran to the door, held it wide open, and called "Come girls, he wants to meet you!"

"Come right in, girls. This one," pointing to a girl with light hair and bright eyes, "is Eloise. Her father keeps the Inn. And this is Josephine, who has no yard at all; and Helena who has plenty of ground; and this," with a grand flourish, "this is the judge's daughter, Katharine."

"I hate," said Katharine, "always being labelled; I think it's pretty hard on a girl to be tagged this way."

"If you'll sit down," began The Chief--"although there are not chairs enough--we'll get right down to business."

And then how they talked! Closer and closer they drew up to The Chief until the eight heads were so close together they seemed almost one huge head. Finally they all shouted with laughter.

"Not a word outside, mind you, not one word. Prove that girls can keep a secret."

"We solemnly promise," said Katharine for the others.

"Look," cried Elizabeth, "there comes Jack; what shall we do?"

"Out this way," quietly replied the man, almost sweeping seven happy little girls out of the door. "Now, cut and run." And off they scampered over the fields.

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."

"Why, we have a piece of ground, where sorrel grows thick; father says that is sour," added George.

"Just a minute, Albert," broke in The Chief; "that is one way, George, that farmers tell a sour bit of land. Weeds grow thickly over such ground, but as George has said, sorrel is likely to predominate. Go on, Albert."

"Any soil may be tested with this litmus. The Chief calls this the scientific way of going at it. I was able to get a little soil from our future garden plot, and I'll find out right now if it's acid." Albert opened a small box which was full of soil that looked quite clayey. He wet a piece of litmus and buried it in the soil.

"We'll have to leave this a few minutes, and I'll finish what I have to say. If soil is very acid it has to be changed back again."

"Back again to what?" asked Jack.

"Why, back again, so it isn't acid," Albert continued, decidedly confused.

"I'll help you a bit," and The Chief came to the rescue, "Get that big bottle over there, Albert." Albert brought the bottle. In it was a liquid clear as water.

"Taste it, Peter," and The Chief handed Peter a little in a small gla.s.s.

"Why it doesn't taste like much of anything; sort of flat."

"That's it exactly, Peter. It certainly is not an acid, is it?" Peter shook his head. "It is lime water and does not belong in the acid cla.s.s, but to one which is exactly opposite to the acids, the alkalies. Soils ought to be neither acid nor alkaline, but neutral, as it is called. An alkali will help make neutral an acid. If the soil is acid it is bad for 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?"
