The starting aiul stopping of I Ik- iic\a- 

 tor as well as the hoisting, shifting, and 

 lowering of the unloaders is controlled 

 hy two men, one on each side of the 

 \essel. On \-ery large liners as many as 

 twelve or fourteen of these electric load- 

 <rs are employed for rushing the coal 

 into the holds of these impatient mon- 

 sters. And even when a fresh bargeful (jf 

 coal is brought up, there is no delay in 

 the operations; the loaders are simply 

 raised and swung over the coal in the 

 barge, and the loading continues. 



What contributes most essentially to 

 the efTectiveness of these portable load- 

 ers, is the fact that they arc self- 

 contained. Within the elevator, steel 

 buckels are connected with rolled steel 

 hinge-pins, so as to form an endless chain. 

 The chute, on account of its telescopic 

 construction, is adjustable to the desired 



length, and distribution is thus made 

 (le.vible. Such floating marvels as the 

 "Imperator" and the "Vaterland" have 

 been coaled by these loaders in twenty- 

 one hours, during which eight thousand 

 five hundred tons were put aboard by 

 ten such machines — a performance that 

 could not have been achieved by the old- 

 fashioned system of hoisted bucket:;. 



Any bulk material, such as sand, 

 gravel, or stone may be loaded or 

 unloaded from one point to another, 

 rapidly and economically. These electric 

 loaders are used to transport a cargo 

 from a freight-car into a truck; or from 

 a barge into storage bins. And when 

 one considers that none of the material 

 loaded is lost, and that the skilled labor 

 of an engineer or his assistants is nf)t 

 needed to operate this device, its claim 

 to economy becomes undeniable. 



An Auto Mountain Railway

FOR the transportation of passengers 

 up Mount Tamalpais in California 

 a number of automobile railway cars 

 of unique design have been devised. The 

 ears arc proi)elled by a sixty-horsepower, 

 water-cooled engine, and there is room 

 in the spacious tonneau for twenty pco- 

 I'le, in addition to the driver. 



The chassis, which is of sjjecial design, 

 is mounted on railwav car-wheels form- 



ing four trucks in all. A special gear- 

 reducing mechanism cuts the speed of 

 the engine down to where it is most 

 efficient for climbing steep mountain 

 grades. The seats arc upholsteretl simi- 

 lar to those in railway cars, and every- 

 lliing possilile has been done to cater 

 to the c(jmfort of the passengers. It is 

 said that this method of transportation 

 has enjoyed great popularity.
