It doesn't occur to some customers to ques- tion how a-business firm can of- fer goods for nothing. If a company has to use "free! goods or premiums to secure its own goods would to be wrong with the merchandising program or the quality of products, says the hardware busi- ness paper. "No company can afford to give away something for nothing if its goods are priced right and are good value for the price asked. "Free" "goods are paid for by the customer in one way or another. sales of there seem' something its WILL PRICE ENQUIRY COST MORE THAN IT SAVES Observers at hearings of the Federal Government's price en- quiry are wondering if the tax- payers are going to get their money's worth out of it, accord- ing to Canadian Grocer. 'Each of the two counsels for the com- mittee is paid $125 a day or $250 for the two of them, The bread enquiry lasted three weeks." But this is only part of the cost, continues Canadian Grocer, "Theré¢ are long distance! calls to be taken care of, lengthy wires, shorthand writers to record the proceedings, reams of paper, plus the ink for the printing of the evidence, and a score and one mated the average weekly cost other costs involved. It is esti- mated the average weekly cost may run close to $5,000.

The children, as usual, left the airplane on the top shelf of the bookcase, and Teddy sat on the floor, looking at it. The room was quite dark. Mary-Jane and _the tin. soldier and Mr. Punch and all the other toys in the playroom seemed to be fast asleep.

He flew over the garden--over the roses and the lilacs and the apple trees-- over the bird bath and the sun dial, He saw the big white rock, and the outside fireplace, and the little house where father kept his tools, and the gate, and the path with the colored stones that led down to the pond.

Perhaps it was only a dream trip perhaps, That's what every one else in the playroom thought. But Teddy didn't care, He knew it had really happened.
