very complete. We have at our disposal two models. 

 They differ only in size from those adopted by the rail- 

 way companies; one of these is simply composed of two 

 thin plates of iron, one over the other ; at their centre 

 is a pivot. These weigh but 90 kilog. (19S lbs.), and 

 at each side a handle is placed which enables two men 

 to carry them with ease. 



We will now say a few words concerning the " por- 

 tem-" (see fig. 42), which is extremely simple in con- 

 struction.

Porteur Decauville. 



This is composed of two T-ii-ons 0.10 m. (0.32 

 feet) in height, which are fastened to the axles which 

 become fixed. On their upper portion are riveted two 

 plates of iron three-quarter inch in thickness. At 

 each end of these is riveted an J-iron. Between 

 the plates is an open space ; this has the advantage of 

 preventing an accumulation of dirt on the platform.
