Plug In Mounting for the Short Wave Coils
A simple inexpensive mounting for short wave coils uses UX tube bases and a UX socket with bakelite strips. Tube bases are trimmed and solder lugs added, then bolted to bakelite. The coil is mounted on a wider bakelite strip with a brass bracket and brass tubing support, using two copper wire terminals for the primary.
Shielded copper cabinets cut radio set loss of selectivity
Robert F Gowen of the Institute of Radio Engineers reports that increasing radio frequency sensitivity worsens selectivity due to interstage coupling. He notes shielding between inductances is essential, with all receivers likely moving to fully shielded copper cases and integrated power units, citing Stromberg Carlson and Browning Drake as examples.

Tap crystal in clamps to avoid circuit disturbance
When using a fixed crystal as a detector it should fit into clamps and not be rigidly attached. Tapping the crystal can reveal new sensitive spots for better reception, but do so only when the crystal is detached from the circuit to prevent loosening connections.
Vegetative Propagation Improves Fruit Tree Root Stocks
United States Department of Agriculture scientists discuss developing better root stocks through vegetative propagation. Root cuttings and layering preserve mother plant traits, offering vigor and disease resistance. Apple, cherry, and plum stock trials show promise for commercial use, with years of orchard testing ahead.

Lawn Clippings Boost Vitamine Intake in Hens, Idaho Study
Experiments at the Idaho Agricultural Experiment Station from 1924 to 1926 show lawn clippings as green feed substantially prevent vitamin deficiency in laying hens. When paired with a balanced ration these clippings nearly rival cod liver oil in boosting production and hatchability, improving profits over feed cost. Trials also indicate dried yeast is unnecessary, and orange juice and lettuce provide enough vitamin A to prevent deficiency.

Growing Onion Crop Yields Tied to Early Planting
The guide notes early sown onions yield best. Sow after hard freeze danger, on weed free ground with litter removed. Plant 3 to 5 pounds per acre in rows 12 to 14 inches apart to ease cultivation.
Agricultural Facts About Planting Good Seed
Agricultural notes emphasize clean cultivation, seed quality, and dusting with arsenate of lead and lime. They warn garlic and cabbage worm control, explain how striped cucumber beetles spread bacterial wilt, and tout crop rotation as the simplest way to systematize farming, including nematode control and limiting sugar beet rotations to every four years.
Methods to Handle Milking Machines Tested by USDA
The U S Department of Agriculture studied several milking machine handling methods after sterilizing units at 100 to 163 degrees Fahrenheit for 20 to 45 minutes. Results ranked effectiveness: weak chlorine solution, water between milkings, refrigerator, then warm room, with bacterial counts of 2200, 2570, 8100, and 5540 per cm3 respectively. Sterilizing at 145 to 150 degrees and holding in water between milkings yielded about 14980 bacteria per cm3.

Duck Raising Made Easy With Warm Weather
Duck raising is easy if begun in warm weather around mid May. Hatchlings should arrive after mid May, fed corn bread crumbs moistened with sweet milk, kept with water and sand, fed five times daily then three meals, then twice as they grow. Allow free range and a dry box. ducks eat insects and grain seeds and stay healthy, with occasional carbolic acid in water for health.

Sour milk feeding advised for chicks
Records show 160 chicks will eat 120 pounds of whole milk in three weeks, or 116 pounds of skim milk, or 93 pounds of buttermilk. Sour milk or buttermilk may replace water in the first feed, but once started must continue. Many poultrymen prefer sour milk for its disinfectant effect, easier digestion, and practical stability in warm weather. Water remains available at all times.
Treatment Necessary to Eradicate Little Mites
Mites are detectable by grayish or red dust near roosts and within nests. Effective treatment must penetrate and not evaporate quickly, as kerosene kills surface mites but evaporates too fast. Eggs in cracks hatch if unchecked, so preventing hatching is essential for success.
Fatten Ducks Market‑Ready Feeding Ration Details
Ducks intended for market should be fattened for two weeks using a ration of three parts corn meal two parts low grade flour or middlings one part bran and half part beef scrape plus eight percent grit and ten percent green feed. Feed mash thrice daily though green feed may be omitted in the final week to prevent over coloring or flabbiness. Boiled fish, when cheap, lowers fattening costs compared with meat scraps.
Hard and soft metals ranked by hardness
Popular Mechanics magazine reports a hardness test state iridium the hardest pure metal with molybdenum and tungsten following. Nickel is the hardest among common metals, thallium is the softest, with lead and tin near the bottom. gold silver copper and iron occupy mid to lower ranks.
