correct practice and to establish that finding as a recommended practice or standard. If the manufacturer does not wish to follow correct practice, it is no concern of this Society.
Mr. Cuffe: I don't think adopting a particular projection speed will help much; camera speeds vary. You can go out on any set and find a speed from 10 up to a great speed. When a director gets his picture in the cutting room, he cuts for a certain projection speed. There are not two directors cutting for the same speed. If the picture is projected slower than that speed for which he cuts, it will drag. Griffith cuts his pictures to waltz tempo and another director will cut to a speed of 100 feet, and when run at a speed less than this, the action will drag on the screen; another will cut to 85 feet.
Mr. Richardson: On what do they base this?
Mr. Cuffe : On the temperamental inclination of the director.
President Cook: We all realize that a standard taking and projecting speed is not possible because it is under the control of the cameraman and director, and the most we can hope for is recommended practice. Standards adopted are very easily susceptible to revision and amendment, and Mr. Schlink of the American Engineering Standards Committee pointed out that it was not desirable to delay adoption of a standard because it was to be changed later. Most of the time of their committee is taken up with changes which are desirable. The procedure for revision is far simpler than for original adoption, and on that account the Standards Committee urged the adoption of standards even tentatively in an effort to clarify features of the industry with the idea that with progress they can be revised to suit new conditions.
Mr. Stewart: No matter what we agree to be standards, there are bound to be certain objections. A film is being made of 16 mm. width mounted on a thin brass base having a 28 mm. sprocket hole.
President Cook: That would not detract from our making standards as fast as we can.
Dr. Gage: For the information of the Society I will say that Dr. Mees will get a letter from the Committee saying that any recommendation he has in mind be reduced to drawings for the Transactions, and these will be presented at the next meeting to find out if the Society wishes to incorporate them as standard. The different manufacturers who sent us the information they did as to projection speeds, aperture dimensions, and so on will get a complete set of all ^the letters sent in to the Committee, so that they can think things
