"Oh, don't worry about that," said the Scarecrow. "Pinhead rivers are only a couple of feet deep. The worst that can happen to you if you fall in the water is a rusty joint or two." "Well, I'd better pack my oil-can then," replied the Tin Woodman seriously. "The Pinheads," explained the Scarecrow, turning to Dorothy, "are almost an extinct breed. You'll find them very interesting. The few that are left live in a small village nearby." Dorothy looked completely perplexed. "But order a river? You mean you can order a river on demand? Just like that?" "Just wait and see," replied the Scarecrow, with a knowing grin. As they approached the Pinheads' village, a few Pinhead children ran out to meet them. Dorothy could see why were called Pinheads. Their heads really were the size of a pin, and when they spoke, their voices were high and squeaky. "Have you come for R and R?" squeaked one of the Pinhead children. "R and R?" questioned Dorothy, "You mean rest and recreation?" With that all the pinhead children burst into a fit of high squeaky laughter. "That's river and raft," explained the Scarecrow, trying to ease Dorothy's obvious embarrassment. "The Pinheads make their living from supplying rivers and building rafts." Then, turning to the Pinhead child, he asked, "How much will it cost?" Just then some adult Pinheads approached. "That depends," said a Pinhead male who appeared to be their leader. "Depends on what?" asked the Scarecrow. "On whether or not you have a pin cushion," the leader replied. "If you do, the R and R will be free." "Well, I don't have one," said the Scarecrow. "And neither do I," said the Tin Woodman. "I have one!" exclaimed Dorothy, digging into her purse. "But what on earth do you want a pin cushion for?" "Well, as you can see," replied the Pinhead," our feet are pointed; and since we sleep standing up, pin cushions make wonderful beds. We just hold our feet tightly together and jump onto the pin cushion and sink down to our heads. It is so cozy and warm, you wouldn't believe it." "I don't understand how that can be," said Dorothy. "I know you are not very big, but this pin cushion seems far too small for you to stand on, let alone sink down to your head." "Oh, that's not a problem for us," replied the Pinhead. "You see, we have the ability to make little things big. How do you think we could make a big raft for you giants? We just make the raft out of match-sticks and thread, and when it's enlarged it looks like it's made out of big logs and rope." "But how do you do that?" exclaimed the girl. "Oh, that's easy," replied the Pinhead. "You see, after the object is made, we look at it under our big magnifying glass. This magnifying glass is no ordinary magnifying glass, but has the ability to magnify things permanently. It was given to our ancestors by a male witch who had no further use for it."
