THE WORLD'S ADVANCE 



to fit a body of any girth. It may be 

 adjusted in a jiffy to encircle the waist 

 of a small boy or girl, or any man or 

 woman from the lightest to the heaviest. 

 This is the first known attempt to fash- 

 ion a life preserver designed to snugly 

 fit the body and allow free, unhampered 

 use of arms and legs in striving to keep 

 afloat until rescued. 



MOVABLE SEATS FOR PICTURE 

 THEATRES 



It has always been a problem to get in 

 or out of a theatre seat without disturbing 

 persons sitting in the same row or in the 

 rear rows. What promises to eliminate 

 this existing difficulty is presented in the 

 invention of a Seattle contractor. This 

 invention consists of a chair which is so 

 constructed that the seat portion is mov- 

 able and has a backward play of about 

 5^ inches. Instead of making it neces- 

 sary for every person in a row to stand up 

 to allow another person to pass in or out, 

 the new chairs enable the person sitting 

 down to slide back a few inches and thus 

 provide ample room for passing. 



PASSERS-BY ATTRACTED BY 

 NOVEL FLORAL DISPLAY 



A florist in New York City has hit 

 upon an ingenious way of attracting the 

 attention of passers-by and thus divert 

 customers into his store. His advertise- 

 ment consists of a window display show- 

 ing a garden landscape in miniature. 

 From one corner of the window a garden 

 hose is suspended, from which water ap- 

 pears to be pouring forth. Instead of 

 water, however, pieces of string are in- 

 serted in the nozzle and lead in all direc- 

 tions over the garden. 



No Longer Will it be Necessary for an Entire Row of Persons 



to Stand Up at a Motion Picture Theatre to Allow One to 



Pass to and from a Seat When These Movable Seats Are 



in Use. 



TREMENDOUS SPEED CHARAC- 

 TERIZES NEW AIR BOAT 



Greater safety and tremendous speed 

 are the important features of a new 

 model hydro-aeroplane which was recent- 

 ly tested by its inventor, Anthony Jan- 

 nus, of Baltimore. The tests were made 

 over historic Fort McHenry. Seventy 

 miles an hour on the water was made 

 by the new machine on its trial trip, and 

 eighty miles was the speed attained in 

 the air. 



Staggered planes. are used in the new 

 hydro-aeroplane ; the upper plane 

 extending beyond the lower for 

 eighteen inches. By this means 

 the lifting power of the machine 

 is greatly increased. 



The uprights used in its con- 

 struction are markedly different 

 from the usual struts, and are 

 made so as to offer the least pos- 

 sible resistance to the passage 

 of the machine through the air. 

 Whereas on the older models 

 there are sixteen uprights used, 

 this machine has but six, so that 

 air resistance from this source is 

 cut one-fifth. These unique up- 

 rights are adjusted to the center 

 of the planes, instead of to the 

 front and rear ends. 



The hull of the boat is 25 feet 

 over all, and in it are placed the 

 controls, engine and aviator's 

 seat. The bow of the boat is 

 made so as to produce a stream-
