On the subject of contributions for the general expenses connected with the present Meeting, the Chairman proposed to request the Bureau of the Union to make the usual arrangements for the collection of subscriptions, on the basis of the decisions of the Organization Committee to the effect that, for the purposes of the present Meeting, the following Administrations and private enterprises should be asked to contribute. a) Administrations and private operating agencies affiliated to the C.

C. A. Communications, Incorporated. d) Administrations not affiliated to the C. C. I. T., represented at the Brussels Meeting and which had expressed a wish to share in the expenses of the Meeting: United States of America • e) Special Cases. Germany, Japan and Spain, affiliated to the C. C. I. T., were unable, for different reasons, to be represented at the Meeting. It was decided that these three countries should not contribute to the expenses of the Meeting. The Secretary General stated that the four Companies referred to under c) above had not yet indicated choice of class for contribution in conformity with the communication from the Bureau of the Union which appeared in Notification No. 548 dated 1st April, 1948. He requested the Companies concerned to be good enough to give the Bureau of the Union the required information as soon as possible. Publication o f Documents. The Chairman said that, in connection with the publication of the documents of the Vlth Meeting, Committee O had declared the view that it was advisable to make the following arrange ments : a) A record of the Plenary Meeting, comprising the minutes of the opening and closing sessions, the series of Recommendations issued by the C. C. I. T., the list of questions for study, the composition of the Study Groups and a list of all documents circulated . before and during the Meeting, to be issued as a service document 6f the International Telecommunication Union; . b) documents circulated before and during the Vlth Meeting of the Plenary Assembly shall, so far as supplies permit, be issued to Members of the Union on request. The Assembly agreed. Composition o f Study Groups. The Chairman said that it was customary at the last Plenary Assembly to appoint the countries which were to participate in the studies of the different Study Groups; but in consideration of the fact that from 1949 onwards the C. C. I. T. would include a large number of countries not repre sented at the present Meeting, he suggested that the Secretary-General of the Union should be entrusted with the task of asking the different Administrations to make known in which Groups they wished to participate. The United Kingdom Delegate pointed out that there would be a certain difficulty in choosing the countries, which would have to appoint the Group Chairmen. The Assembly, on the proposal o f the Italian Delegation decided to proceed immediately to the appointment of those countries represented at Brussels which wished to participate in the work of the different Study Groups. The countries which were to provide the Group Chairmen would be appointed at the same time, on the understanding that any Administration not represented at Brussels, which wished to participate in the studies of the C. C. I. T. from 1st January, 1949 onwards, would merely have to send in its name in due course. The Chairman proceeded to take the names of countries desiring to participate in the different Study Groups, and the Assembly appointed the countries which were to provide Principal Rappor teurs. 5 The Study Groups to be composed as follows : Group Participating countries Countries to provide Group Chairmen 1 : Brazil, United States, France, Italy, Poland, United Kingdom Italy 2 : France, Italy, Netherlands, Poland, Portugal, United Kingdom, Sweden Netherlands 3 : Austria, Denmark, United States, France, Italy, Netherlands, Poland, Portugal, United Kingdom, Czechoslovakia France 4 : United States, France, Italy, United Kingdom United Kingdom 6 : Argentine, Austria, France, Italy, Portugal, United Kingdom, Sweden France 7 : Austria, Denmark, France, Italy, Netherlands, Poland, United Kingdom, Czechoslovakia United Kingdom 8 : Austria, Denmark, France, Italy, Netherlands, Poland, Roumania, United Kingdom, Switzerland, Czechoslovakia Czechoslovakia 9 : Argentine, Canada, United States, France, Italy, Netherlands, Poland, Portugal, United Kingdom, Sweden, Switzerland, Czechoslovakia Portugal 10: Denmark, United States, France, Italy, Netherlands, Poland, Portugal, Roumania, United Kingdom, Sweden, Switzerland, Czechoslovakia Ttaly 11 : Austria, Belgium, Denmark, United States, France, Italy, Luxembourg, Norway, Netherlands, Poland, United Kingdom, Switzerland, Czechoslovakia Netherlands For Study Group 5 France alone gave in its name. The Swedish Delegation was not prepared to provide the Chairman for this Group on the ground that, as the Swedish Administration was concerned with questions relating to protection in the C. C. I. F., it could not usefully participate in studies on the same question in the C. C. I. T. The Secretary-General observed that in the C. C. I. T. of 1949 a large number of extra-European Administrations would be interested in questions relating to the protection of telegraph lines, especially overhead lines liable to be disturbed by power line circuits now in process of develop ment. He concluded that Group 5 should be retained. The work which it would be called upon to do would undoubtedly prove to be of great interest. Finally, the Chairman proposed to entrust the Bureau of the Union with the task of consulting Administrations on membership of Study Group 5 and the appointment of its Group Chairman. Agreed. Next Meeting of the C. C. I. T. The Chairman announced that the Netherlands Administration was prepared to assume the duty of organizing the next Meeting of the Plenary Assembly of the C. C. I. T. in 1951. He proposed that the Assembly should ratify this choice, and he warmly thanked the Netherlands Delegation for its acceptance of the task. The Assembly signified its approval by warm applause. i 6 POSTPONEMENT UNTIL 1953 OF THE NEXT C.C.I.T. PLENARY MEETING AND
