New gadgets and devices showcased for field testing
A roundup of new inventions includes a two part adjustable heel disk held by screws and a 75 foot rolling mast for ship like gyrations on land. A lightweight test mast aids U S Armed Services with cross country fuel line testing and safe magnetic stirrers for hazardous labs. A pin opened English stain remover comes in gelatin packs and there is a handleless quilted vinyl handbag with four pockets. Researchers invite inquiries by mailing a three cent stamp to Science Service in Washington for Gadget Bulletin 494.

Alligator and Crocodile Differences in Form and Temperament
The article compares American alligators and crocodiles noting nose shapes blunt versus pointed, differing tooth alignment, and jaw fit. It contrasts dispositions with alligators described as sluggish while crocodiles are active and aggressive toward prey.
Splash erosion shown by high speed camera study
A Navy research study by W D Ellison uses stroboscopic photography to prove splash erosion from raindrops. The work demonstrates how drops dislodge soil, form a cylindrical water soil mix, and scatter earth, with larger drops causing greater displacement and potential topsoil loss.

Law of Diminishing Returns Governs Wool Growth
Australian scientists Ferguson Carter and Hardy of CSIR report wool production follows diminishing returns with ample feed and temperature. They show faster fleece growth yields long thin fibers while slower growth yields short thick fibers, suggesting heredity sets an ultimate limit. The long-range study assesses environmental and genetic factors across sheep breeds.

Nature Ramblings on a Park Squirrel and Rodent Kinship
A column recounts a humorous encounter with a park squirrel as a disdainful passerby dismisses it. It notes rodents diverse in form and notes the squirrel’s decorative value and busyness gathering nuts for winter. The piece blends humor with zoological tidbits about rodents and park life.
The Squirrel in the North Woods
A red squirrel in the northern countryside is described as a chatty, clever forager. He nags his mate and rivals yet stays a meticulous marketer of winter stores, discerning nuts and seeds with notable efficiency.
Concrete Dome Rises 100 Feet In Cleveland Center
A 100 foot diameter dome was formed over a wooden mold in Cleveland using a gunite mix of cement sand and water blown at 30 psi. The 18 000 square foot shell will be copper sheathed, four inches thick weighing over 500 tons. Architect Eric Mendlesohn also designed Hadassa Hospital in Palestine. The dome at the Cleveland Jewish Center is a landmark project.

Cosmic Ray Photos Over Minnesota Studied by Feminine Physicists
Italian physicists Margherita Addario and Sara Tamburino analyzed cosmic ray plates taken about 18 miles up over Minneapolis. Balloons carried the plates from the University of Minnesota. 488 atomic collision events were found, each showing multiple particles. They compare high altitude records to surface plates, noting energy loss in the atmosphere explains fewer explosions near the earth.
