A Novel Tea-Table Made From a 

 Mill Stone 



SINCE farmers now rarely bring their 

 grain to a small local mill to be 

 ground, the old millstones have gradually- 

 settled to the bottom of the rubbish heap. 

 Many have been broken up, but the 

 lovers of antiques 

 are now 

 the 

 ones. 



In the illustra- 

 tion is shown an 

 old stone found in a 

 New Hampshire 

 mill. It is now 

 used as the tea- 

 table. Remem- 

 bering the Biblical 

 warning that "on 

 whom it shall fall 

 it will grind into 

 powder," it is set 

 on a stand of rocks 

 which have been 

 firmly cemented 

 together. 



Benches or in- 

 dividual seats of 

 stone are appro- 

 priate for use with 

 such a table.

A French Inventor Improves the 

 American Harvester 



ERNEST BONNET of Nonancourt, 

 France, has made important im- 

 provements in an automotor harvesting 

 machine, 

 which 

 facilitate 

 cleaning 

 and mov- 

 i n g the 

 machine 

 from one 

 place to 

 another. 

 The work- 

 ing parts 

 of this 

 new har- 

 V e s t e r 

 may be 

 complete- 



The working parts of this new harvester may be completely 

 uncoupled. The engine in front drives the whole mechanism 



ly uncoupled. The front tractor is at- 

 tached to a trailer which comprises a 

 harvester, combined with connections for 

 transmitting rotary motion from the 

 motor to the trailer and power-control 

 mechanism on the trailer. 



Power is so transmitted that the driver 

 can unclutch the driving wheels for halt- 

 ing the vehicle, 

 without stopping 

 the operation of the 

 working parts. 

 The reverse effect 

 canbeobtained,and 

 the driving wheels 

 can be made to carry 

 the vehicle forward 

 without setting the 

 other mechanism 

 operating. 



The traction 

 wheels are hung on 

 vertical pivots 

 with a bridge con- 

 necting them. This 

 bridge carries a dif- 

 ferential gear. A 

 divided axle com- 

 municates move- 

 ment from the dif- 

 ferential to the trac- 

 tion wheel. Uni- 

 versal joints are 

 provided coinciding 

 with the vertical pivots of the wheel. 

 Transmitting mechanism for communi- 

 cating rotation from the motor to the 

 differential gear completes the combina- 

 tion. 



Will machines, such as this, shortly be 



used on 

 our great 

 Mid -west- 

 ern farm- 

 ing lands? 

 Assuredly 

 tractors, in 

 one form or 

 another are 

 to work 

 great 

 changes in 

 our agri- 

 cultural 

 methods 

 in the very 

 near future.
