0 words perday is roughly 150 times the actual traffic sent across theAtlantic Ocean by cable and radio at the present time. A number of perfectly reasonable requirements must bemet by transmitting and receiving stations in order torealize the ultimate capacity mentioned above, accordingto Mr. Goldsmith. The transmitters must have strictlyconstant generator frequency consistent with their keysignaling speed and the receivers must be highly selectivefor a correspondingly narrow range of frequencies andyet follow the signals accurately. Even today radio en-gineers are confident that these results will shortly beobtained by carefully chosen technical expedients. The nature of world communication makes it interna-tional in character. Both wire lines and radio waves knownothing of national boundaries, a fact which is sometimesresented by the nations, particularly during hostilities.It is this essentially international character of long-dis-tance communications, particularly of the unguided

In 1912, the London Radio Con-vention was agreed to by most of the nations of theworld and given force by corresponding national legisla-tion in each case. These regulations of the London Con-vention were fairly general in character and covered themost essential points only. Thus there was left con-siderable and proper leeway for each nation to settle itsown national problems in communication according tolocal needs and the nature of local institutions. It wouldseem that some such policy is wise, especially where im-portant matters of truly international scope clearly requiresettlement in the interests of eiTecive communication andto avoid inevitable disputes. Beyond this point which isdefined without much difficulty by the experts in the art,regulation becomes burdensome and tends to retard theprogress of the radio art and to discourage initiative. For the rapid growth of world commu
