University of Chicago "Reveals the numerous ways in which the atmosphere plays a part in altering the earth's surface . . . Shows how tem- perature variations result in the dis- integration of rocks by spalling, and how temperature variation together with chemical action of the atmosphere resxilts in another type of disintegration called exfoliation. The action of the wind in eroding rocks is explained by animation and photography. The movement of sand, loess, dust, and volcanic dust over great distances on the earth's surface is . . . visualized."

Rothacker ajid made in cooperation with Texas gulf sulphur company "Reel one shows by animated photog- raphy how sulphur is melted 1,000 feet below the earth's surface by superheated water and is forced by compressed air to the surface where it is run into huge vats and solidified; also shows building of vats and blasting and loading of sulphur into cars. Reel two shows how sulphur is used—for drugs, fumigating arid bleaching, in the preparation of dried fruits, in the rubber industry, in explosives, in the paper industry and for sulphuric acid.

'For- mation of Soil' [Class 551.3] this film should give the child an understanding of the rock-soil cycle in nature and its com- mercial significance. It shows the weathering qualities of granite, and the relationship between granite, quartz and sand. Artificial sandstone blocks are made, natural sandstone is quarried, cut into blocks, and fashioned into grindstones. Other processes such as the making of brick, tile, and pottery are shown. The film has been divided into the following units: sand, glass, clay."
