...Camp Kearney, near San Diego, Calif., ten thousand people assembled one morning last week to watch the U. S. S. Akron dock for refueling after a turbulent transcontinental passage. Poking through a gradually lifting fog, the great ship dipped slowly three times, three times was whisked up by rising strata of warm air before the ground crews could grab the spider lines from rings on two dangling cables. The fourth time the crowd cheered as the crew caught hold, started to tug the Akron's tossing silver nose toward the stub mast...
...various parts of the city, the filling now is largely being taken from the bottom of the basin. Borings were taken at 500 foot intervals each way over the entire extent of the basin to determine the character of the river bed and the depths of the various strata. In general, the bottom consists of a layer of mud and silt, under which is a layer of gravel, and below this is clay or hard pan. A curious thing that was made apparent, after dredging began, was that in sections of the basin there are large beds of oyster shells...
...week President Thomas Gilbert Pearson of the National Association of Audubon Societies concluded an airplane inspection of the many blue geese that winter in southern Louisiana. Near the mouth of the Mississippi he encountered a flock three miles long, half a mile wide. The geese were flying in three strata. Dr. Pearson estimated there were between 600,000 and a million of them. Because they migrate so quickly hunters get less than 1,000 of the two millions that winter in Louisiana. Audubon experts are satisfied that the blue goose is one American wildfowl that has not decreased in numbers...
...working on experiments at Roswell, N. Mex. under patronage of the Smithsonian Institution and a Guggenheim fund. His magnum opus is a proposed turbine rocket ship by which the exploding gases will drive propellers while the ship is in lower atmospheres, change to direct rocket action in the upper strata where propellers lose efficiency...
...demand for wheat for food in most countries is comparatively inelastic. In order to tap extensively the strata of elastic demand-for food in China, for example, for feed in many countries, and for industrial uses-prices cruelly low to wheat producers are necessary. Temporarily this may be inevitable...
