Over two hundred coils were built up in this manner in search of the proper diameter, size of wire, and general over till dimensions of the oil, consistent with low losses and efficient inductance. The colls held together with string proved to be too flimsy for practical use. so a form was designed to hold the winding, made of a material that did Hot add to the capacity of ihe coil. Now that the indentations In (lie winding for allowing string to lie threaded through to hold the wire's together were no longer necessary, It was found that they were responsible lor the low- distributed capacity losses and the high performance of tin' coils.

Doctor Nature is exceedingly busy in the national parks this summer. The national park service reports, with the season yet several weeks from Its peak, that till records for attendance will be broken. And that Is a good thing for the nation. For outdoor recreation amid scenes of natural scenic beauty is tiie best antidote for the many ills of our modern civilization. Doctor Nature in the national parks is showing her patients a wonderland.
