Theuse of the latter only results in the accumulation of trashon the back of the tender, which soon gets mixed up with coaland water, and often becomes frozen; It is always a useless deadload, which, to say the least, Is untidy. When this space aboutthe manhole is clear and exposed to sight It can be kept neatand clean. The use of oblong manholes for tenders Is becoming general, IS their use renders it unnecessary to make a water tank stop n exact spot, but some margin is allowed in each Fig. 2. It was at first thought by some that this advantage could bebest secured by placing the long axis of the manhole parallelwith the track, and some tenders were built in this way, butit toon became evident that a larger range could be obtainedby placing the long axis crosswise of the track, and this loca-tion is now always used where the oblong fixture is intro-duced (see Fig. 1). The old method of bracing tanks was crude and flimsy, re-quiring frequent renewals and repairs. It consisted of cross-bracing about the center of the height of the water leg—usinground bars or flat strips with pin connections and crow-feetor angles on the sides. The small section of the parts madethem deteriorate rapidly by corrosion and wear, due to con-stant rattling of loose joints. With large tanks and high sidesa much better and simpler form of bracing is now used. Oneof the best Is the use of vertical pieces of heavy tee iron about3 by 3% inches thick,
