This section is in consid- erable detail. Next is a view of the Yar- row Experimental Tank, and the model— which is fitted with an electric motor and screw propeller—is seen being lowered into the water. An actual test run is por- trayed, and it is possible to get some idea of the wave pattern. One is then intro- duced to the method of producing artificial waves, and a run is made in rough water. The film closes with pictures of one or two modern ships. The photography is very good and the spoken commentary excellent. The film is rather too bHef to satisfy the needs of technical students. . . [Suitable forj naval architecture and ma- rine engineering instruction for students in technical colleges and universities; of general interest to people living in sea- ports and shipbuilding centres."
