The Bridge over Mirror Lake. It is made from a long shallow box with a cover.
Material Required to Make a Box Bridge: a long cardboard box with cover, a strip of cardboard about ten inches long.
When you look at the picture of Box Bridge, you will easily see, I think, how it is made. It may be used in many ways for play. Your toy railway system may have a bridge as well as a freight station and tunnel. A box bridge may connect opposite shores of Silver Paper Lake, and the delivery wagon from Boxville's General Store may jog happily over the bridge to deliver goods at Boxville Cottage. Guests from Hotel Bandbox may fish from the bridge. I am sure you will find many other things to play with it, so I will tell you how to make one, even though it does seem as if you might almost make one without directions!
Take the box that you wish to use for a bridge. Remove its cover.
Turn the lower half of the box over so that the bottom of the box becomes top. Cut a semicircular piece from each long rim. This makes the long arch of the bridge. (See Diagram Four, A, page 173.)
Next, take the box cover and turn it so that its top is next to the top of the bridge. The lengthwise rims of the box will be a railing for the roadway over it. Cut each end rim at the corner, and let these end rims be pasted each to a strip of cardboard cut to fit the width of the box, and join the bridge roadway to the road along the floor where you are playing. Each strip of cardboard glued to an end of the bridge may be about five inches long.
If you wish to make more than one bridge, you may easily do so. The shape of your box, whether deep or shallow, will make a different kind of bridge. The landscape of your Boxville may be as full of silver paper streams and foot-bridges, railway bridges, covered bridges, toll-bridges, as you please!
London Bridge may fall down,
But my Box Bridge stands true! I'd rather own a Boxville Bridge
That stands up - wouldn't you?
