Imitation Hand Signals a Turn 



AN imitation hand has been devised 

 by a California merchant to watn 

 traffic that his automobile is about to 

 make an off-side turn. It is attached 

 to one of the rods supporting the top. 

 On the rear of the top side of the hand 

 is an eye, to which a string is attached. 

 Whenever the driver wishes to turn a 

 left-hand corner he pulls the string and 

 the hand goes up. 



This device costs less than ten cents 

 and obviates the danger of losing con- 

 trol of the steering wheel. The arm is 

 painted black and the hand white. 



Sea Shells for Decorating Concrete 



A CONCRETE worker of Long 

 Beach, Calif., has discovered a new 

 use for sea shells. The accompanying 

 illustration shows an interesting speci- 

 men of his work. It is a garden orna- 

 ment constructed of solid concrete, dec- 

 orated with small mussel shells. The 

 shells, arranged in rows and squares, are 

 imbedded in the concrete with the inside 

 of the delicately colored shell exposed. 

 The structure is intended to enclose a bed 

 of flowers, and vines will be trained over 

 the top. The same design may also be em- 

 ployed to surround a garden fountain. 



Shells make concrete decorative 

 in detail as well as in line
