and Chute Tower. Railway, for the drawings, photographs and information whichform the basis of this description. Coal bunkers used for the storage of coal to be loaded into ves-sels have usually been built out into the water, and as it is nec-cessary to provide for vessels of deep draft, the substructure hasnecessarily been very costly, especially in salt water where tim-ber work is exposed to the attacks of the teredo. An additionaldifficulty arises on account of tides, the extreme range at tie the entire bunker. One is stationed at the particular gate of thebunker from which the coal is being taken. He regulates theflow of the coal into the conveyors. The other man is stationedat the front end of the bridge, where he has control of the motorsand where a number of levers are arranged by which all the dif-ferent movements are governed. The machinery for the bunker was furnished by the Link-Belt Machinery Company, of Chicago, The specified capacity of 294 AMERICAN ENGINEER, CAR BUILDER

The capacity of the bunker itself is 17,000 tons, enoughfor three or four good-sized cargoes. The average time consumedin loading a vessel is about 15 hours, depending somewhat on thedispatch it is possible to give to the trimming of the vessel. Sincethe bunkers first started no delay has occurred to any vessel onaccount of the stage of the tide. They have been able to takecargo on their arrival and finish it without interruption. The adaptation of electric motors to these operations is of par-ticular interest, and from an examination of the plans we re-produce it will be seen that by their employment a very simplearrangement of the machinery is made possible. The motors are capable of attaining high speed and overcomingconsiderable gradients. Signed statements of more than 200 residents of 125th street bearevidence to the fa
