struction of dry docks, dams, piers, walls, 

 fortifications, etc., also for open pit min- 

 ing, quarrying, logging, discharging vessels 

 and transferring cargo between ships at 

 sea. 



A splendid view of a battery of Lidger- 

 wood Cableways as used on the Chicago 

 drainage canal forms the frontis piece to 

 the book, and is followed by an example 

 of the use of the traveling cableway in 

 constructing the dry dock of the Newport 

 News Ship Building & Dry Dock Co. 

 Considerable space is given to the Lidger- 

 wood Cableway on U. S. Government for- 

 tifications, notably at Gerrish Island, Me., 

 where the cableway is used as a high- 

 speed, long-reach, traveling crane; alse at 

 Fort Morgan, Mobile, Ala., Fort Pickens, 

 Fla., Willets Point, N. Y., Fishers Island, 

 N. Y., and Tybee Island, Ga. 



On some of this work a new type of 

 Radial Traveling Cableway was employed, 

 wherein the lead tower is arranged to 

 travel about the other thus covering a wide 

 area for excavating and delivering concrete 

 and other material directly to any part of 

 the work. 



A chapter is devoted to " The Lidger- 

 wood Cableway on the High Seas," which 

 presents various views and a complete de- 

 scription of the Miller Conveyor for coal 

 ing vessels at sea, recently tested and ac- 



cepted by the U. S. Navy Department, 

 and which has already received much at- 

 tention from the technical and daily press. 

 Views are also published of the traveling 

 dock cableway with overhanging boom for 

 discharging coal from vessels as well as 

 for reloading barges and boats. 



Placer mining by means of the cable- 

 way with self-filling drag bucket, describes 

 very thoroughly and attractively a plant 

 furnished by the Company to the German 

 Bar Mining Co., at Virginia City, Mont., 

 which employs a Lidgerwood Cableway of 

 the radial type. The patented drag bucket 

 is of novel construction and is claimed to 

 be absolutely the highest development in 

 its line. 



Following chapters are devoted to the 

 cableway for digging sand and gravel, for 

 building bridges and piers, for handling 

 pipe, quarrying, open pit mining, coal 

 stripping, etc., showing several important 

 plants. The Lidgerwood transfer for dis- 

 charging vessels and for use in coaling 

 sheds, gas houses, and large manufactur- 

 ing plants is shown with special attention 

 to the Miller-Covell double swing fall rope 

 carrier. The volume is a very creditable 

 piece of work throughout and furnishes 

 valuable information as to the capabilities 

 of the cableway as built by the Lidger- 

 wood Mfg. Company.
