Robbing the Sea of its Salt
OUT IN California salt is being recovered from sea water in commercial quantities. The pictures below show details of the process.
In this shallow pond sea water is evaporated and its salt content crystallized out. Note the ridges of salt along the edges of the pond.

WELL known to European tourists but passed by most globe trotters —who in their hurried journey across seas and continents, have no time to bestow on anything outside of the beaten tracks—are the salt mines of Wieliczka, Galicia, whose origin is lost in the darkness of the times, while their history is traced to about 1000 A.

CELLAR FULL OF GOLD
Only Fort Knox has more bullion than the vault under 33 Liberty Street.
THE TALE of the yardbird who kept moving a pile of bricks back and forth endlessly is acted out with international significance in the solid rock cellar of the Second District Federal Reserve Bank in New York, where six and a half tons of gold worth $8,000,000,000 are kept to back up currencies of 60 foreign countries and the International Bank. In this man-made mine, stackers have to move the stuff brick by brick from one triple-locked cell to another as one nation’s balance drops, another’s goes up. •
Eating for Death
By Bernarr Macfadden

It is the direct cause of more suffering, weakness and disease than any other evil.
It poisons the life stream at its very source.
“The blood is the life.” The quality of this liquid determines vital activity throughout every part of the body.
Rubber-Balloon Globe Puts the World in Your Pocket
CARRYING the world in your pocket is no task with this balloon globe designed to keep you abreast of world events. The rubber balloon can be inflated by three or four lungfuls to a diameter of eight inches. The neck is then twisted and passed through a slot in the cardboard disk which is used as a base. The globe’s scale is approximately one inch for 800 miles. To put the world back in your pocket, just pull its neck out of the slot in the base and let the air escape.
