���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

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.
