Growing Science Clubs of America Hydroponic Basin Method
An article describes a 16 foot long asphalt-lined wooden basin for soilless culture with detailed construction steps. It explains using roofing paper, securing seams with asphalt paint, and creating watertight flashings. It introduces a hydroponicum seedbed and notes crop suitability for annual plants like potatoes and tomatoes.
Building a Seedbed Tank for Hydroponic Growth
Instructions for a seedbed tank with a one inch mesh bottom, galvanized wire, and a moist excelsior base. Details cover seed sowing, litter depth, aeration, liquid level management, and basic hydroponic chemical mix. Includes invitation to start a Science Club via Science Service.
Hydroponic Gardening Opens New Door To Home Growers
Dr William F Gericke of Berkeley explains soilless hydroponic gardening using basins filled with nutrient water and a litter of sawdust or excelsior. Simple to build from rough lumber, it yields large crops like tomatoes and potatoes even in ordinary soil. Begin with potatoes tomatoes corn and beans then interplant for higher total yields.

Rubber Off Roads Could Be Salvaged for Tires
Dr. Carl Omeron of Los Angeles suggests street rubber can boost retreading material. He estimates at least one pound per tire wears off yearly across the city streets and highways. About 1,400,000 registered vehicles would leave roughly 4,000,000 pounds of scrap rubber for reuse.

Cats Learn to Distinguish Musical Chords, Psychologists Claim
Brooklyn College researchers trained four cats to respond to the C major chord on an accordion by rewarding correct choices and ignoring bell noises. The study, reported in the Journal of Psychology, suggests learning the whole chord pattern rather than individual notes, with the B major chord posing the greatest difficulty.
