HE WAS SO young that he scarcely had accurate control of his tiny legs. Long, yellow curls nestled to his neck and hung about his shoulders. And he gurgled gleefully as the barber, with his scissors, snipped off curl after curl. Over in the corner the mother watched, a timid, half-frightened expression on her face.

The Real Problem of Prohibition

Donald Wilhelm
A NEW chemical warfare is ravaging the bodies of millions of Americans, threatening the general health of the nation. To combat it seems a task more difficult than protecting an army against military poison gases. It challenges doctors and public health officials more than infant mortality, more than ordinary epidemics, more than keeping our milk, our drinking water and our food supplies free of pollution.

Without a sound the great ice pan slips away from the shore and out into the current that rushes through Bering Strait and on to the Pole. Their hunting finished, the men and women—nine black dots on fifty square miles of ice—pack their seals and start for home.

Into her home she had welcomed a tall young man of 27 years who, having just graduated from Yale College, found himself stranded in a strange city, penniless and without friends.

IF YOU are tempted to complain of the bread and biscuits your wife makes, go slow. The trouble may be not in the baking, but in the flour. For one thing, the flour may be ground too fine. Two chemists of the Food Research Institute at Stanford University, Drs. C. L. Alsberg and E. P. Griffing, have just discovered that too much grinding injures the starch in the grain. As a result, bread rises too fast at first, and then falls. Excessive grinding also injures the gluten, which makes bread dough elastic, and then the dough is difficult to knead.

It is large enough to hold 100 cigarettes. The interior of this radio cigarette box is divided into two compartments. The one to the right holds the cigarettes, while the one at the left contains the mechanism connected with the dialing system.

FIVE members of the Bayside Canoe Club were seated on the end of their dock, basking in the sunlight of the first really warm June day of a cool and backward season. "Well, boys," spoke up Fred Nelson, the club's commodore, "if we’re going to build that swimming float, we had better take a run over to Captain Graham’s and see if he has figured out a good plan for us to follow."

HENRY LOWE BROWNBACK
MOTOR BOATING is SO splendid and invigorating a sport that boat owners invariably take a keen personal interest in the repair and maintenance of their boats. A man may be willing to leave the upkeep of his auto entirely to a service station, but he feels his motor boat deserves that sympathetic handling and patient attention to details that no one but himself can give.

OF ALL the things that injure health, straining the nerves is more dangerous than all others combined. It weakens the nerves, paralyzes the organic forces, plays havoc with the mind; and is the cause of innumerable dangerous ailments. Nerve strain is especially harmful to the stomach and bowels, causing nervous indigestion, sluggish bowels, and kindred disorders.

WHEN the rigging on your radio mast or flag pole breaks and repairs are needed at the top of the pole, the only solution often is to climb the pole or take it down. Not everyone is an accomplished pole climber, and even if you can climb, it is rather difficult to do any effective work at the top, such as unfouling the tackle or running a line through the block.

WHILE woodworkers are familiar with silver solder as a medium for joining band saws, its useful properties sometimes are overlooked by many mechanics. Silver solder is an alloy of about 70 percent silver and 30 copper, with sometimes other metals in small quantities.
