THE WORLD'S ADVANCE 



TIDAL TRANSPORTATION 



Some of the finest grindstones in the 

 world come from the bottom of the Bay 

 of Fundy. The stonecutters there have 

 a simple method of moving them to the 

 shore. Workmen quarry the stones from 

 the solid rock when the tide is out, and 

 fasten them to a large flat-bottomed boat. 

 The tides in the Bay of Fundy are the 

 highest in the world ; they rise from 50 

 to 70 feet, and rush in- with great swift- 

 ness. The tide lifts the flatboat with 

 the stones attached ; the workmen bring 

 the boat ashore and remove the stones 

 at their leisure when the tide is out. 



STARTLING ADVERTISING 



A man dangling by his hands from the 

 roof of a building is apt to startle pas- 



sersby and cause them to stop and almost 

 call for help. It invariably makes a man 

 pause long enough to investigate. This 

 fact has been adopted by a western firm 

 in conjunction with its advertising. In 

 these days when so much advertising is 

 done by billboard, it takes either a very 

 clever or startling device to attract the 

 attention of the passerby and take his 

 thoughts away from his own affairs. 



A CENSUS OF POLES 



The 900,000 miles of telegraph and 

 telephone wires that now form a vast 

 network over almost every part of the 

 United States and Canada require the 

 support of no less than 35,000,000 poles. 

 It is said that about four million poles are 

 needed annually for renewals and new 

 lines. Well-stocked German forests, 

 which are the best managed forests in 

 the world, produce only 250 trees to 

 the acre; the poles now standing would 

 thus represent all the timber growing on 

 more than 130,000 acres. In Canada 

 considerably less than one hundred poles 

 are cut to the acre, so that nearly 500,- 

 ooo acres of forests have been cut to 

 obtain the poles now in use, and about 

 50,000 acres are cut over each year to 

 furnish the poles for renewals. That 

 means cutting at the rate of a hundred 

 acres a day. 



A Dummy Figure Dangling from the Eaves of a Roof 

 and Carrying an Advertisement Makes the Aver- 

 age Passerby Pause Long Enough to Investigate. 



A TWENTY- YEAR CALENDAR 



While there are a multitude of calen- 

 dars in existence which enable any one 

 to determine a desired date ten, twenty 

 or even a hundred years hence, there are 

 but few of them that are ready for in- 

 stant use. Most of them require consid- 

 erable figuring, tabulating or the moving 

 of shifting scales in order to secure the 

 desired date. 



A Brooklyn man has recently pub- 

 lished a twenty-year calendar which has 

 for its main feature extreme simplicity. 

 Any date can be found immediately, and 

 it is so simple that even a child can 

 consult it.
