McCampbell has designed a mechanical spreader which. manned by three men, does the work of 25 men with shovels. Some farmers put their faith in the "hopper dozer," a shallow tank about 20 ft. wide, filled with kerosene, which is mounted on wheels or runners and pulled along by a horse at each end.

...Streltsov had built chambers in which he tested the ability of various animals to live at low pressures, translatable into equivalent heights above sea level. Best performers were guinea pigs and turtles, which got along at the equivalent of 13,000 metres (about 43,000 ft.). Dogs and cats could not hang on long above 12,000 metres, carrier pigeons collapsed at 7,000. Newborn rats and mice, however, which were given no chance to get used to air of normal pressure, survived amazingly in air of .002 of sea level pressure, which corresponds to an altitude of 30 miles...
