...Clarence W. Hansell of Rocky Point, N. Y. and assigned to Radio Corp. of America, the apparatus emits radio waves so short that some of them bounce back from an obstacle to the sending point, where they are focused so as to create a tiny image on a copper sulfate screen.* The picture emerges as a white silhouette on a blue background. If the obstacle is a ship, its distance can be inferred from the size of the image...
Deep Rays. Near Mohawk, Mich., the Seneca Copper Mining Co. has a mine shaft which slopes down at a 34° angle to a vertical depth of 1,600 feet. Volney C. Wilson, research assistant of the University of Chicago's famed Arthur Holly Compton, worked for three months in the shaft with a cosmic ray recorder of his own design, containing four ionization tubes. These were arranged in line so as to exclude cosmic rays shooting down the open shaft, to catch only rays boring vertically through the rock. From the surface to 1,600 feet Mr. Wilson...
...filled-in swamp nine miles from Manhattan, once beloved by rats but now graced by two artificial lakes, handsome landscaping. Only building finished is the Administration Building where most of the Fair Corporation's 900-odd employes work and where dressy President Whalen holds forth in a copper-lined board room.

Most of the New York Fair's space has already been...
...Scheming Jack," his brother, was also gifted. As a boy he made a pair of copper wings and attempted to fly; he also invented a cradle which rocked itself. To escape schooling and go a sketching, Tom himself proved resourceful. Once he successfully forged his father's signature to a note which asked the schoolmaster to "Give Tom a holiday." When his father discovered the fraud, he shook his head and prophesied: "Tom will one day be hanged." But when he saw how he had spent the stolen time, he changed his mind: "Tom will be a genius...
Audubon, hypercritical of his own work, would never have passed the present pictures, which have suffered from the reduction in size and difference in the method of reproduction. The "elephant" folio was exquisitely engraved on copper and aquatinted (principally by Robert Havell, who edited as he transcribed Audubon's watercolors, here deleting a leaf-spray, there toning down a garish sunset sky, altogether contributing much artistic merit to the pictures). Plates for the new edition have been reduced and reproduced by mechanical, sometimes fuzzy lithography. Nevertheless, the pictures' cumulative effect makes the book exciting. The wild turkey, giant...
