FIG. 103. Inclined Railway with Special Car. 



Apparatus Storage. In many cases material must be delivered 

 at certain times before it is needed, i.e., during the summer navi- 

 gation, before the rainy season, while the ground is frozen, etc. 

 The question of storage, therefore, needs careful consideration, 

 as there usually is insufficient room in the power-house, espe- 

 cially before the building is completed. 



The castings and rough machine parts may be stored in the 

 open. A derrick for unloading and reloading will answer on small 

 jobs. On large installations it may prove advantageous to install 

 one of the main cranes or a forebay crane on a temporary track 

 supported on timber framework over a skidway. Finished parts 

 must be protected from the weather, fittings and small parts from 

 sneak thieves.
