Heat Causes Wavy Fur in Muskrats
E A McIlhenny of Avery Island Louisiana argues heat from marsh fires causes permanent waviness in muskrat fur. He notes dozens of farmed muskrats show permanent waves after ears and tails scorched by fire and regrowth patterns with occasional white tufts.

Atlantic Seaweed Replaces Jap Agar
War boosts value of two seaweeds along American coasts. Giant kelp supplies agar substitutes under U. S. Fish and Wildlife Service trials. Irish moss or carrageen, collected mainly near Scituate Massachusetts, rose from 24000 in 1939 to 100000 last year, used in ice cream medicine and shoe polish.

Roses Yield Vitamin C in Bird Berry Study
British scientists analyzed dog rose hips after wild birds showed fondness for them. They found hips contain about 20 percent more vitamin C than oranges, offering a promising source as Britain faces scarce vitamin C foods. Country folk collect hips for jam and winter puree for soups or cocktails with a tomato-like flavor.

New Gadgets And Inventions For War Industry
Science Service reports rapid production of compact high voltage X ray outfits with 40 built in a year, capable of penetrating eight inches of steel. Stainless clad sheets save stainless and brass, while new goggles protect eyes in hot weather. An expansible dynamite cartridge reduces spilling, and metal blackout awnings telescope for full window coverage. Plastic graters replace tin and provide cleaner looks. For details, request Gadget Bulletin 112 with a three cent stamp.
Evolution of the American emblem from rattlesnake lore
The National Emblem by Science Service explains the rattlesnake as a patriotic symbol prior to the final Continental Congress adoption of the eagle. It notes troops once carried flags featuring a coiled rattlesnake with the motto Dont tread on me and describes earlier flag designs in military bodies.
