Editor's Notes
Re: Shortt, Blake and Phelps transmitters. Phelps' is simple and works well "but if people can get patents on these things after your covering the whole ground, as it seems to me your have, I dont see what he Patent Office is for or what is the use of getting a patent in the first place."
