Other drawings, motion picture closeups and panoramas visualize the ori- gin of moraines, crevasses, 'ice tables,' glacial rivers, glacial valleys, etc." Pro- ducer sh Guide 551.36 Coast changes Shore deposits.

Films of commerce 551.36 Produced by Pathe "How incessant pounding of waves against a shore is an Important factor in shaping shore lines is portrayed in this film. The picture shows how the nature of the bordering cliffs determines the charac- ter of beach material. Excellent examples of shore formations in this film are those of Plymouth, Massachusetts; Nahant, Mas- sachusetts; Boston Harbor; and Rio de Janeiro." Indiana Jh-sh Shore lines and shore development. (Har- vard Pathe ser.) ISmin 16-si-$24 35- si-nf-$60 1929 Films of commerce 551.36 Produced by Pathe "A study of the forces which are shaping the coast lines of the continents and the shores of lakes. The picture considers the two main types of waves commonly developed in the sea, and shows the work which they accomplish in changing the shore line. Both kinds of work accom- plished by waves and currents, erosion and deposition, are shown by the resulting beaches, cliffs, caves, bars, spits, etc. The fury of storm waves is emphasized." Distributor Jh Study of shore features—bold shore. lOmin 16-si-$20 35-si-f-nf-$40 1921 Soc. for visual educ. 551.36 "Designed to show how, by the action of water, rough and rocky shore lines are given greater and more magnificent in- dentations. Dr. W. W. Atwood draws a cross-section of sea level, waves and sea cave. He shows how the under-cut shore above the cave collapses; how waves some- times cut through weak places in the rock to form arches. Motion pictures show a panoramic view of an arched rock near shore. The formation of gravel bars and land-tied islands is traced, and a fjorded coast-line is pictured." Producer Guide Study of shore features—low shore. 12min 16-si-$24 35-si-f-nf-$50 1921 Soc. for visual educ. 551.36 "Designed to illustrate how wave-action gradually changes a low shore line from a shore of bays and indentations to one of comparatively smooth lines. Dr. W. W Atwood, in one of his famous 'chalk talks,' visualizes the work of the sea in building banks, reefs, bars and capes. Such splen- did harbors as those of Provincetown, New York, Presque Isle Bay on Lake Erie and Duluth on Lake Superior, are shown to be the result of the building of sand hooks."

We can actually see and experience the subsidence of the mouth of the Hudson River to form the present harbor of New York; the events that have preceded in the story of the Appalachian Mountains; and the story of the famous and spectacular Lewis Overthrust in the Rocky Mountains. The film opens with a photographic survey of the type of evidence which constitutes the basis of these interpretations, and closes with a consideration of the signifi- cance of these phenomena to mining and structural engineering." Iowa univ. sh-c Guide 551.44 Caves Caves in limestone and coral growth. ISmin 16-si-$24 35-si-nf-$55 1922 Soc. for visual educ. 551.44 "How water seeping through the earth's crust wears away the softer parts of some ledge of rock many feet below the sur- face. In this way underground tunnels and caves are made. Then, step by step, the diagrams picture how constant dripping of water from above, filled with lime par- ticles, causes stalactites and stalagmites to form. After a time some of these unite, forming columns that divide the cave into rooms. What coral is, where it grows, and the kind of land it helps to make, are shown by Dr. Atwood in this . . . chalk talk. He explains the condi- tions most favorable for coral growth, the origin of 'fringing reefs,' 'barrier reefs,' 'circle reefs,' the effects of a raised sea- level, etc. The tremendous size of some of these circle reefs is . . . visualized."
