Beam Wireless Is Scientists Goal
Dr J H Dellinger, chief of the Radio Laboratory at the Bureau of Standards, surveys the quest to concentrate radio waves into a directed beam. He traces Marconi’s early parabolic reflectors, the beam system’s British adoption, and the limits of sharp directivity. He notes navigational uses like the directional finder and its value in fog for mariners.

Simple Way to Avoid Corroded Battery Contacts
Battery storage owners often hear noises first blamed on static or loose connections, then traced to corrosion on positive terminals. The article explains the whitish corrosion, its damage to wires, and a grease-cover method, plus a safer placement of wires to keep air and acid fumes from reaching contacts.
Simple Bus Bar Method Improves Battery Insulation
A concise procedure uses six inch bus bar pieces, a soldering iron, and solder. Each battery terminal gets a bus bar piece soldered, and a clip on the lead wire is fastened to the opposite end. This keeps the contact point away from the battery and away from fumes.
Grid Leaks Define Best Detector Reception
The article explains how grid leak resistance in detector tubes must be correct and stable under operating and climate conditions to avoid energy loss and distortion. It notes inked-paper leaks vary and cause noise, but a fixed metalized resistor grid leak can remain in circuit, with higher plate voltage requiring higher leak values and multiple resistors recommended for experimentation.

Tasmania Schenectady Radio Record Sets Five Minute Transit
Broadcasts from General Electric station 2XAF in Schenectady featured a live five minute Australian radioAddress by four members of the Australian Industrial Commission. The 82.79 meter wavelength program ran 5:30 to 5:48 am before amateur operator 2AHM in Schenectady relayed a test from Hobart Tasmania 7DX. The report praised clear reception and even mic rumble.

Rejuvenating Plan Questioned as Not Fully Practicable
A discussion cites experts doubting the practicality of rejuvenating tubes in radio equipment. It notes success by some fans but warns effectiveness hinges on the specific rejuvenating gear and proper operator use. Overloading mistakes and improper follow up can negate results, with mixed approaches like gradual overload or initial high power.
Better Eggs Poster Promotes Quality Standards
A United States Department of Agriculture poster highlights the key traits of good eggs. It explains that yolk and white quality reveal freshness, shell strength reduces breakage, and proper storage preserves flavor. Householders are urged to buy discriminately and display the 14 by 20 inch poster from USDA Washington DC.

Korean Lespedera Good as Pasture
A small seed package from Korea introduced to the United States Department of Agriculture yields eight ounces of seed from Arlington Virginia trial plots. The Korean lespedeza proves drought resistant, adapts to poor acid soils, and serves as a summer pasture crop with reseeding ability. Its best prospects lie from southern Pennsylvania to northern Ohio, and toward the Atlantic to Iowa, with seed supply currently inadequate. The USDA urges farmers to harvest seed for sale as demand remains strong and seed cannot mature north of described zones.

All Vegetable Crops Hurt by Wireworms
The article advises on wireworm control for garden and field crops. It covers preplant baiting with clover dipped in Paris green, poisoned corn meal dough, and careful use to protect children and animals. It recommends crop rotation, limiting sod years, interplanting peas and clover, and deep soil cultivation in late summer to destroy undeveloped pests.

Agricultural Facts Seed Oats and Livestock Feeding
Agricultural notes advise not clipping seed oats and warn that cows fed alfalfa leaves in mangers indicate excessive protein. It covers marketing surplus male poultry as broilers versus capons, corn borer risks to corn dependent farms, and cabbage with solid three pound heads selling for higher prices, recommending intermediate Danballhead as best.
Fish Too Cold Die Across Atlantic And Antarctic
The article notes millions of fish die from cold currents across the Atlantic and in Antarctic waters. It describes how fish hauled from 30 degree water froze to death when exposed to air at 70 degrees colder.
