Popular science monthly . tte placedin. A fine cotton thread 9 is then tied to By J. S.

The ends ofthe rattan ribs are then brought to-gether and secured to a cork A^, similarto cork A. The cork and rattan frame are solight that the balloonettes readily liftthe structure. For that purpose twobent pieces of rattan 10, 10 are used,placing one at each end of the frame, sothat they embrace the upper and lowerribs4,6,towhich they are firmly attachedby threads. The lower or looped endsare some distance below the frame. Thepropeller is attached to the forward loop10. It is made of firm cardboard, firststeamed, after which the tips are twisted,and after being dried are fixed to the smallend of a shoe eye 12. This serves as a. Details of the toy Zeppelin bearing for the propeller. A wire 11,passing through the eye has a hook atits rear end, to which a rubber band 13can be attached. The other end of the rubber band isattached to a hook on the end of a wire 313 314 Popular Science Monthly 14, the body of which rests in theloop 10. The rear end of the wire isl)ent at right angles, as at 17, and has adouble bend as at 18, to furnish a crank,and also provide a means to lock thecrank after winding up the rubber. The next operation is to provide apair of elevating planes and a fore and aft planes are similarlyconstructed, the forward one 20, beingattached to the upper rib 4, and the aftplane to the lower rib 6. Each plane is2 by 4 ins. and at one margin is a pair ofslits 22, 22, running into holes whichare made to correspond with the verticalloops 10, 10, to which they are other margin has a single slit 23,with a terminal hole, which is attachedto the rib of the fr
