The Sixth International Congress of Animal Husbandry held in July, 1952, at Copenhagen was valuable from more than one point of view. While the cynical may say that we suffer from too many conferences the fact remains that we have now entered a period where co-operation of one kind or another between European countries will almost certainly increase. This being the case it is as important that we should find the best way to make international conferences more efficient as it is to listen to papers and discussions arranged at them.
