ticnce, practice, and breath control which, if pursued diligently, will result in what he terms "cleanness of tone." He suggests daily routines of scales and arpeggios with emphasis on playing longer and longer phrases in order to expand the hnigs and wind capacity of the performer. The film closes with the rendition of The Tres Mendez Polka by Mendez and his two prize pupils, his scventctnyear-old twin sons. Ralph and Robert. Appraisal The Trumpet is another excellent film by the producers of the widely accepted "Concerts on Film" series. It succeeds in bridging the gap between the performer and his audience as no recording or "live" concert can do. In so doing, the film creates a greater understanding and appreciation for a musical instrument which, although familiar to all of us, is so seldom well played. It should prove most valuable to teachers and students of the brass instruments as a motivational device and as an insight into the personality and technique of a superb artist. The exceptional quality of the sound track on this production serves to impress upon the listener Mendez' great flexibility, clearness of tone, and remarkable control of the instrument. The fact that the narrative becomes lost at times due to Mr. Mendez' thick accent in no way detracts from the purposes for which the film is intended. The previewing committee agreed that the film would also be a stimulating experience for band and orchestral groups ranging from the junior high school age through the adult level. — Mrs. Elizabeth J.

Description Through the activities of two elementary-age children this film outlines the steps that should be followed in preparing and maintaining an aquarium that supports various kinds of tropical fish and explains the reasons and the importance for maintaining a balance between plant life and animal life in such an environment. As the film opens, the Henderson family is boating on a lake; their children, Susan and Fred, are watching the fish near the surface of the water. Both children express an interest in raising I fish at home, and their father agrees that they may if they jnomise to learn to take care of them. The children are then seen in their living room as Susan finishes cleaning the glass of an aquarium tank. Fred, who has been washing sand, puts it into the tank. Green plants are then added and the narrator points out that they are as important as the fish in making a healthy acjuarium. Susan then adds clean water. Susan measures ihe temperature of the water in the aquarium and also in small fishbowls containing fish for the aquarium to be certain the temperature in both is the same. Pairs of various tropical fish — swordtails, black mollies, dwarf gourumi, neon tetras, angelfish, and guppies — are introduced into the large aquarium. As the fish seem to be enjoying tlieir new home, the question of what is meant by a balance between plant and animal life in an acjuarium is raised. The plants are observed to be giving o(f a gas — oxygen, which the fish need for breathing — while the fish give off a gas — carbon dioxide, needed by the plants for making food along with sunlight. This balance is further explained through an animated drawing.
