INTERNATIONAL REVIEW OF POULTRY SCIENCE OFFICIAL ORGAN OF THE WORLD'S POULTRY SCIENCE ASSOCIATION EDITOR: DR. B.J. CTEHENNEPE ROTTERDAM (Holland) Published by: Frifz Pfenningsforff, Berlin W 57 Printed in Germany. To the Members of the World's Poultry Science Association. As First President of the Association and promoter of the World's Poultry Congresses, of which I had prevously dreamt for several years, the Editor of our Review has asked me to send a message of greeting and of stimulus to every member throughout the world. I do so in gratitude at having been spared so long to see and share in the Congresses held up to the present time. I rejoice to see how these have grown in interest and importance, not only by the numbers in attendance, but by the influence exerted in promotion of the Poultry Industrie. Probably there are more people who are interested in the ^Jbreeding of poultry than in any other branch of agriculture, certainly of live stock. One of our great objects has been to so advance and 2 improve methods that greater success will be achieved, and dangers in 3 the shape of increased mortality may be prevented. To that and other ends practice and science must work in unison. One chief aspect of the Poultry Congresses has been and is the bringing together of those engaged in production, in education and in research. Much has been done to prove to governments and 'teaching centres that those engaged in Poultry Breeding and Production are serving consumers in the great centres of population by producing eggs and poultry flesh. In that respect there is more yet to be accomplished. What impresses me most in writing this message is the fact that fifteen years have passed since the first Congress was held, and how many there are who then shared in what was pioneer work, an endeavour to build for the future, have passed away. I did not expect to see the Sixth Congress to be held this year, but that has been the case and indicates that we do not know of our opportunities for service to our fellows. Whether I shall be here when the next Congress is held it is impossible to say. Therefore, as we older men and women pass away, the need is for younger men and women to take up the work and carry on for future generations. We have touched a few of the problems which are evident, and which may be leading to those which are of greater importance. The call is insisten á for workers in the different fields, so that as we pass from the stage there may be no slackning of effort. Successes there have been, failures more. At any rate there has been an earnest end- eavour and considerable accomplishment. 3 /* First and foremost my hope is that the Leipzig Congress may prove to be the greatest and most influential of all the series. Each of those preceeding it have marked a greater or lesser step in advance, certainly in interest. From what I have seen in connection with the Organising Administration at Berlin, and the preparations at Leipzig my hope is that every Member of the Association who can do so, and large numbers from every country who are interested from any point of view, will attend the Congress meetings and see the great Exhibition. These can hardly fail to help them whatever their labour, opportunities and location may be. In that way they will contribute to the progress of mankind. One thing more, namely, there are many members of the Association whom I have never met though we may have corresponded. If present at Leipzig I hope that they will make themselves known so that we may, for once at any rate, know each other in person. That will be a pleasure I shall look forward to realise. With all good wishes and warmest greeting, your colleague and servant, EDWARD BROWN, Hon. Past President. For the 6*^ World's Poultry Congress. The Vlfh World's Poultry Congress from July 24fh fo August 2nd 1936 in Leipzig will be the most important event for all smallstock breeders, especially for poultry breeders of the entire world. Germany has mobilized her best capacities to serve this great event. The preparations for the Congress have advanced so far that the last little detail has already been arranged and settled. At his last visit in Berlin and Leipzig, Sir Edward Brown, Honorary Past President, of the World's Poultry Science Association, has had the opportunity to convince himself of the state of affairs. He has expressed his satisfaction about the fact that arrangements in connection with the Congress have been carried throught up to every little detail. Sir Ed- ward Brown has the right to expect that the Vlth World's Poultry Congress will be the largest and most significant meeting of its kind. Germany expects for this Congress guests from all countries and will receive them in her usual hospitable way. She will show them everything, German science, German practice and German efficiency have contributed during the last years in the poultry breeding line. We have noted with pleasure that participation from all countries will be extraordinarily lively, as it is our aim to make this Congress really an international meeting of men and women of the entire world. Germany expects representatives from many countries at the Vlth World's Poultry Congress. We shall take every care to make the stay in Germany for our guests from foreign countries as pleasant as possible. We hope and wish that they will return to their countries with the feeling to have got into contact with an active and peaceful people and to have learned something about their aims and their work. The beauty of the German countryside, which we will show at a Post-Congress-Tour, will be a harmonic conclusion of the Congress. We have everything well prepared for receiving you. Be our guests from July 24th to Aug. 2nd at the Vlth World's Poultry Congress. Karl Vetter, Member of Council W. P. S. A., Director of the VI th World's Poultry Congress The World's Congress. Sir,—In view of the statements issued by the German Committee of the Sixth World's Congress to be held in Leipzig, it is unnecessary for me to enter into detail of the programme. I have had so many enquiries, however, from those who would like to be present that it may be helpful if my impressions are given of a recent visit to Berlin and Leipzig, in which I have had been in close contact with the Government officials and those in charge of the arrangements for the Congress in both cities. So far as the country is concerned, everything appears to be normaL That is so alike in the cities, industrial centres and rural areas. Work and pleasure în the cities are evident. In the rural areas are extensive developments for settlement of the unemployed on the land, which present features of great interest. Thousands of houses have been erected, each of which has a plot of land for cultivation, and also to enable the breeding of poultry and rabbits to be carried out. The plans for the Congress and Exhibition are practically complete. As the general secretary stated, they could open both within a week, if necessary. Leipzig is not only a city of historic interest. It is a beautiful one, with magnificent buildings, several of which will accommodate the Congress, including the Sessions. The great buildings where the celebrated Leipzig. Fair is held every six months are practically ready to accommodate the Exhibition, which is an integral part of the Congress.
