Modern Radiotelephone Receiver Redesigns and Construction
Carlton E Butler outlines improved radio receiver designs addressing squealing tone and poor quality. He describes the Ref o circuit with five tube tuning, depass condensers, square toroid coils, shielding condensers, and dustproof features to tune through interference and improve sound. He lists parts and wiring details for building the R-1 receiver.

Straight Line Tuning Bid for Simpler Radio Tuning
The article discusses the rise of straight line tuning with the straight line frequency condenser and the S. U. FL dial converter. It notes the goal of simplifying short wave tuning by providing one dial visibility and reducing condenser adjustments, while acknowledging the S. L. FP converter dial is mechanical and cannot fully resolve electrical tuning problems.

How to Tune Circuits Avoiding Body Capacities
The guide advises tuning with the terminal closest to ground potential to minimize body capacity. It explains that in most circuits a variable condenser is tuned across access with rotor plates tied to the filament circuit. The hand approaches these plates as the shaft carries the dial.
Cut Down Distortion in Audio Transformer Setup
A method to reduce distortion by wiring a variable grid leak across the secondary of the second audio frequency transformer. The adjustment targets stabilization of gain and linearity in the high fidelity audio path.

Cover Crops Slightly Affect Orchard Frost Height
USDA weather bureau experiments in California orchards show cover crops such as purple vetch and beans slightly raise frost risk but hardly change temperatures. At five feet, air cooled by 0.1 F. at ten inches, 1 F cooler. Windbreak effects and ground moisture also influence frost damage.

Plan the farm garden before planting time
J G Moore of the University of Wisconsin horticulture department urges gardeners to plan before planting. He compares planning to a carpenter drawing a blueprint, stresses layout of rows and planting sequence, and notes soil drainage and texture as key factors. He recommends raised beds for low marshy land and adding organic matter to improve heavy soils.

Milking Three Times a Day Increases Cow Milk Output
United States Department of Agriculture studies show cows milked three times daily yield more milk than twice daily. Short term gains reach 12.5 percent with longer periods showing even larger increases. Three daily milkings improve end-of-lactation output, while cost of labor and product value affect overall economy.

Seed Grain Planted in 1926 Needs Treatment
Dr C F Stakman of the University of Minnesota urges all farmers to treat seed grain from 1926 to prevent smut. He notes a high smutted rate in 1925 wheat and offers copper carbonate dust and formaldehyde treatments detailed in Folder No 13. Free copies available from the agricultural extension service at University Farm St Paul.

Selecting Pure-Bred Sires for Dairy Herds
Charles J Bray of Colorado Agricultural College argues that pure-bred sires must be well balanced, proven by offspring, and bred from high producing ancestry. He warns against mixed breeds and emphasizes consistency, long-term use of one breed, and using sires with strong pedigrees to maintain herd value and production.

Good Feeding Pays Well in Production of Milk
A Grinnell-Newton Cow Testing Association study of seven pure-bred cows shows feeding more concentrates increases milk and butterfat output and net profit. From February to March costs rose but profits grew. April limits on silage and alfalfa required more concentrates, with minor changes in butterfat cost.

Creatures of Habit in Dairy Management
The article argues cows thrive on consistent routines for grain and water, warning that switching feeding times or watering patterns disrupts their rhythm. It emphasizes rotating feeds at the same daily time and maintaining the same water schedule to avoid misses.
Dairy notes on cream separator use and cow feed
The document stresses proper speed and even pressure on the separator handle for milk cream separation. It notes alfalfa hay as top roughage due to protein and palatability, and advises separating milk quickly then cooling to about fifty degrees. It discusses ensilage feeding rates and the need for legume hay for high milk yield per acre.
