Since the last report in 1960, a total number of 25 grants has been made to 27 astronomers. This is about the average number of the last ten years. Considering the increasing importance of astronomy, one might have expected a quicker development of international travel and exchange. All efforts should be made to stimulate the mobility of astronomers and to make effective use of the wonderful possibilities now available. It should be stressed that the IAU grants can be awarded for a stay of any duration of time, and that practically all applications are answered positively and quickly.
