Varying Inductance of the Tuning Coil
The article reviews tuning coil designs for radio receivers, comparing single layer solenoids, variometers with cylindrical or spherical windings, basket winding, and spider web coils. It discusses mechanisms to vary inductance, leakage issues, and optimal coil configurations for short and long wave tuning.
Shrinkage Records Show No Flavor Difference in Pork Grades
Tests by the United States Department of Agriculture on 800 hogs found total weight loss from cooler to retaining period was 13.85 percent for oily pork, matching firm pork. Soft pork shrank 16 percent, but flavor and keeping qualities were similar across grades, with appearance driving market preference. Bulletin 1086 details the tests and is available free from USDA Washington.

Don’ts for Early Radio Users From a 1920s Guide
Practical tips warn on insulating antennas and avoiding door mounted switches. Advice covers not wiring parallel runs, not tying antenna ends to poles, and avoiding direct radio connections to the electric circuit. Cautions on tickler coils, indoor antenna limits, and wire handling including annealing copper to prevent breakage.
Magnet position boosts audion tube sensitivity
A large horseshoe magnet placed with poles on each side of the tube may increase audion sensitivity. The effect likely arises from magnetic influence on electrons moving from filament to plate.
Length of Aerial Wires in Telegraph Installations
A single wire aerial suffices if at least 75 feet long can be erected. For shorter wires use two wires with the leading-in from the far end. If the total length is 50 feet or less, employ a four-wire setup and take the leading-in wires from the far end.
Proposal to expand broadcasting wavelengths by station shifts
A proposal suggests increasing available broadcasting wavelengths by adjusting several 860 meter stations by 25 meters or more. The plan aims to widen frequency options and improve service coverage across the network.
Radio sparks and progress in early broadcasting
Edison’s work on electrical current and vacuum tubes influenced early amplifiers though his hearing loss slowed radio development. Notes cover radio in forest fire alerts, eight British stations planned with listener fees, ship radio dead spots in the Red Sea, overhead wire antennas, and youth galena finds for sets. Warnings about worthless stock circulate.

Increase value of manure by phosphate use
The phosphate addition does not always double manure value but can greatly improve it on exhausted soils. Soils depleted by long grain cropping or long livestock feeding respond best, while farms saving all manure and feeding all hay and grain see less dramatic gains. On many farms east of the Mississippi phosphate enhances manure usefulness overall.
