We see a general overview of the country and then a map locating several mines including the Freeport mine in Louisiana. A general view of this mine followed by shots of men at work. Diagram showing unconsolidated substance, barren limestone, sulphur-bear- ing limestone, etc. Now shots of the sul- phur wells. Then with actual views and diagrams we see how one of these wells Is constructed and the mining carried on, following essentially the method Invented m 1891 by Dr Herman Franch, with im- provements added throughout the years. Many shots of the power plants and reser- voirs are shown. We see also an up-to- date machine shop necessary to keep all this machinery in order. The commentator explains that once started a well must keep going 24 hours a day seven days a week and anything needing It must be repaired immediately. More processes are shown, using views and diagrams. Then we see great mountains of the sulphur which has been permitted to solidify. It is blasted down and loaded on to a train by crane. A closeup of the cars used for this purpose. A loading platform at Freeport Harbor. Here the sulphur is loaded on to ships bound for all parts of the world. Shots of an endless belt conveyor loading sulphur on to barges. A general shot and shots of the various processes while the commentator tells many of the things for which sulphur is needed. We see a model community provided for the sulphur work- ers. Then we learn that sulphur Is pro- duced extensively in other ways in other parts of the world. Then the film goes into color. Vats of liquid sulphur, the moun- tains of solidified sulphur, the endless belt, tug pulling a loaded barge—all in beautiful color, while the commentator gives statis- tics and history of the industry. This color sequence is available only on the 16mm versions "A fairly complete film giving a good impression of the value of sulphur in our modern life and of the processes used In deep-well mining of sulphur. . .

Now the commentator tells of other ways to obtain sulphur and some samples of crystals, etc. are shown. The rest of the film is given over to a series of experiments performed using sulphur in combination with other materials sh 575 Evolution How the earth was born.
