surroundings. Even a few Navajo rugs 

 were spread where their barbaric colors 

 would brighten the corners. Then the 

 public was invited to make a rendezvous 

 of the garden, and the response was 

 prompt. The store sold talking ma- 

 chines and records, so a noon-time con- 

 cert was an attraction and a large num- 

 ber of sales resulted from placing the 

 customers in pleasant surroundings and 

 making them comfortable. 



FEDERAL JURORS EAT CAKE 

 MADE OF EGGS TEN YEARS OLD 



Cake made of eggs ten years old was 

 served to jurors in the Federal district 

 court during the hearing of a suit 

 brought against a former collector of the 

 port of New York by an importer, to 

 recover $12,000 damages because a con- 

 signment of Chinese preserved eggs in 

 w T hich he had an interest was destroyed 

 as unfit for use. The eggs had been pre- 

 served by boracic acid in a solution, and 

 tasted good to the jurors who ate them, 

 despite their extreme age. A professor 

 of biological chemistry testified that it is 

 possible to keep eggs 100 years by this 

 method without impairing their quality 

 or taste. 



A GASOLINE - OPERATED TAMP- 

 ING MACHINE 



One of the latest additions to the ranks 

 of labor-saving machines is a tamping 

 equipment that is operated by gasoline 

 power. The machine not only does the 

 tamping in a more efficient and expe- 

 ditious manner than is possible by man- 

 ual labor, but it also effects a consider- 

 able saving in the cost of work of this 

 kind. 



The tamping machine operates a 150- 

 pound ram at the rate of forty to fifty 

 22-inch strokes per minute. Comparing 

 the machine with manual labor immedi- 

 ately discloses its vast superiority. The 

 average laborer with even a fifteen-pound 

 tamper will not average more than twenty 

 strokes per minute, and with a heavier 

 tool the rate is proportionately less. Fur- 

 thermore, he will hardly lift the tamper

more than nine or ten inches. Not only 

 does this indicate that the machine tamps 

 down the ground in a more firm man- 

 ner, but it also proves that the speed is 

 far greater. 



The tamping machine can travel about 

 under its own power at the rate of 

 eleven to thirteen miles an hour. When 

 at work it travels forward or backward 

 at a speed ranging from six to fifteen 

 feet per minute. The motive power is 

 furnished by a four-horsepower gasoline 

 engine. 



It is claimed that the tamping machine 

 will replace from eight to ten men under 

 favorable conditions, and even under the 

 most adverse conditions, such as short 

 jobs, it replaces anywhere from three 

 to five men.
