mpanying engravings, which were made fromthe working drawings of the company, give a very goodgeneral idea of the exterior and interior of the station whencompleted. As will be seen from the most cursory glanceat these drawings, the engineers of the company have in-corporated in their designs the most approved modernmethods of steam generation and utilization, and in abouta year from this date, or at the outside a year and a half, will of course immediately follow the erection of the steelsuperstructure. The foundations are composed of about 5500 piles, sup-porting a monolithic mass of Portland cement concrete 4ft. thick, the piles and concrete being surrounded by awall of sheet piling made up of hard pine timber 6 ins.thick, splined, and driven to a depth of 40 ft. below thesurface. The contract for this foundation work was placedwith F. E. Shaw, of Providence, last September, and, asstated above, is nearly finished. The strata underlying 288 STREET RAILWAY JOURNAL. (Vol. XIX.

Beneath the founda-tions of the buildingare constructed twowater conduits, ofsufficient size for aman to walk through,to furnish water forcondensing purposesand to discharge thewater after it has beenused. These conduitsextend to the channelof the ProvidenceRiver. Under thebuilding these water-ways are made ofconcrete; between thebuilding and the riv-er they are timberflumes. A screenchamber is placed inthe intake. There arealso foundations forthe coal-h o i s t i n gtower, which will beerected at the watersedge upon the wharf.These are show
