...front. "The music box played Silent Night," he remarks. "I fixed it to go 'ping, ting, click' instead." Prize exhibit in the Museum of Modern Art's "Recent Acquisitions" show last week was a Johns target, messily painted in red, blue and yellow atop a layer of old newspapers pasted to canvas. Attached to the upper edge of the canvas was a boxlike arrangement containing the lower parts of four faces, done in tinted plaster...
...increases suddenly at a certain level under the earth's surface (the depth varies from place to place). This suggested that the Moho marked a dividing line between different materials. Geologists believe that the Moho is the bottom edge of the granite and basalt that forms the lower layer of the earth's crust; under it is the earth's mantle consisting of a mixture of silicates and nickel-iron, which in turn encloses the nickel-iron core...
...Moho to an impossible depth. The best place to drill is the floor of the great ocean basins. The floor may be three miles beneath the ocean's surface, but the Moho lies only three or four miles deeper, under a thin skin of sedimentary deposits and a layer of basalt...
...they were moved to the sail to keep them as far as possible from the sonar in the bow. Another trouble is control. The Skipjack's maximum depth has not been announced, but even if it is better than 1,000 ft., the ship has a comparatively thin layer of water in which to maneuver. Cruising at 40 knots (67½ ft. per second) close to her depth limit, a slight error in the up-and-down steering will carry her down to hull-crushing depths in seconds...
...demand for the more prolific egg layer has required more and more automation. Near Atlanta, Ga., Layer Breeder Roy Durr produced 500,000 chickens last year trying to keep up with orders for layers. He puts the eggs in special incubators that vastly improve on the maternal solicitude of real hens. A hen often forgets to turn her eggs (causing the membrane lining to adhere to the shell and killing the fetus), or in hot dry weather leaves the nest and lets them dry out. Durr's mechanical mother turns each egg every hour, and when a thermometer warns...
