Iceberg Structure and Submerged Ridges Endangering Ships
The article explains how icebergs melt to reveal knife like submerged ridges that can rip hulls. It notes the visible portion is about one eighth of the total volume and details how melting creates circular undersea gorges, shifting the center of gravity and making submerged parts extend beneath the surface.

Candy Medicine: A New Era for Children and Adults
A Chicago expert describes medicines redesigned as candy to disguise dosages. Gold fillings may spark electric currents from metallic drugs in chocolate or fondant, while quinine and phenacetine can be flavored to taste pleasant. The approach aims to ease administration for children and invalids, sparking debate over trust and taste.

Electrified insect killer for orchards proposed by W R Frost
W R Frost of Spokane outlines an electrical device to murder moths in Western orchards. A storage battery powers 6 candie lamps netted with steel as moths fly to light, complete circuit, and drop dead into a receptacle. One unit per acre could reduce spraying and equipment costs if central station service extends to orchard tracts.

Travelled 400 Million Miles in a Year of Space
The article explains that 400 million miles measures our end-of-year distance from the start, not mere orbital travel. It describes the sun’s velocity, earth’s spiral orbit, star motions, and the Sun’s apex moving about twelve miles per second, with Vega and 61 Cygni as reference points in a vast cosmic drift scenario.
