Everything was there but the engine and they substituted a burro for that 



A "Jackomobile" for Two 



THE illustration shows a combination 

 of the oldest and newest means of 

 transportation. In 1904 it was a new 

 automobile, but in subsequent years it 

 fared so hard at the hands of one 

 owner after another that its engine was 



discarded and the machine itself was 

 on the way to the dump heap when two 

 boys assumed ownership. They ob- 

 tained a burro and after fitting the 

 body of the old model with shafts, went 

 about their Michigan town with the 

 only "Jackomobile" extant. 



The Milk- Can Trolley 



FOR the rapid and economic handling 

 of milk a Western creamery has 

 installed an aerial tramway, si.x hundred 



The ..ipaatus in position, showing the 



carrying and traction cables. Two cans 



are always in transit 



feet long, leading from its milking barns 

 direct to the refrigerating and bottling 

 plants. The milk travels over the top 

 of stables en route, and a complete trip 

 of one five-gallon can on a two-wheeled 

 carrier takes but sevcnty-fi\'e seconds. 

 Formerly this work was done by a 

 driver with team and wagon. The 

 tramway has taken their place. 



There are always two cans in transit 

 at the same time, one coming in full and 

 one returning empty. The attaching 

 links are so spaced that when the full 

 can has reached the end of its trip at the 

 bottling house, the empt>' can has also 

 reached its destination at the milking 

 barn and stojjs at the i)rt)per jilacc, 

 automatically. The drag-cable isdrixen 

 by a reversible set of small ilrums 

 having grooves to receive the cable. 

 Signals to start arc given from the barn 

 by a magneto bell. 



l'"or dairies which handle large (juanti- 

 ties of milk and make express shijiments 

 to large cities, this conveyor is a great 

 step in advance, since it reduces the time 

 re<iuire(l in handling the milk.
