594 KANSAS CITY REVIEW OF SCIENCE. 



sion of the main building, 600x220 feet, filled with machinery for picking, ginning 

 and pressing cotton and also wood-working machines ; beyond this another vast 

 room 600x60 feet for heavier machinery, such as saw-mills, etc. Adjoining this, 

 in the main building, are found all kinds of milling machinery ; also the exhibits 

 of the Willimantic, Coates, Clark, and Whitin spool cotton companies; the first- 

 named occupying seventeen spaces, or about 200 feet, with the various machines 

 employed in manufacturing spool thread, all in full operation, with crowds of 

 interested spectators watching the successive processes the cotton passes through, 

 from the raw staple to the spooled thread. Near by are the Corticelli Silk Com- 

 pany's headquarters, where can be seen everything connected with the manufac- 

 ture of spool silk, from the silk-moth, the egg, the silk-worm the cocoon, the reel- 

 ing of the silk from the cocoon, the spinning, winding, the to coloring, spooling, 

 etc. 



Going back to the machinery, we find nearly in the center of the main build- 

 ing the motive power which keeps all the other machinery, as well as the dyna- 

 mos for the electric lights and electrical display in motion. Principal among 

 these engines is the huge Corliss engine set in operation on the opening day by 

 an electric signal from President Arthur from his room in the White House ; but 

 there are nearly a dozen others, aggregating oveY 4,000 horse-power, grouped 

 together in that locality. Near these is a wonderful display of sugar machinery, 

 railroad engines and cars of all kinds and other heavy machinery, including some 

 very old-fashioned locomotive engines and an electric railway of the most recent 

 date. The ice machines are by no means the least interesting objects, especially 

 to the people of the south, and there are specimens of several patterns, besides- 

 refrigerators in all styles and sizes. 



In agricultural machinery the display is comparatively light, and I think that 

 I have often seen more of all kinds on exhibition at the Kansas City Expositions. 



The electric Hght is a success. Most of the principal companies of the 

 country are employed to furnish light, such as the Brush, the Edison, the Fort 

 Wayne, and a home company. Thousands of electric lamps, inside and outside 

 of the buildings, give ample light for all purposes, so that visitors who can not go 

 out in the day time can see just as well at night. The Brush Company have the 

 lighting of the government building where the National and State exhibits are dis- 

 played, and employ six of their largest dynamos for generating the electricity 

 needed for the 3,600 lights furnished. The Edison Company light the Main Build- 

 ing and Agricultural Hall with over 4,000 incandescent lamps, and have twelve 

 dynamos operated by six engines of 125 horse power each, with a capacity 

 of over 6,000 lights. When the Art Hall is finished this company is to light that 

 also. The Fort Wayne Company light the outside towers — about ten in number 

 — including those at the entrance to the grounds and buildings, also the sheds, 

 stables, etc. These towers are very handsome, being light, ornamental in appear- 

 ance, and very strong. One of them, placed at the " Lake, " is of 100,000 candle 

 power — said to be the largest single electrical light in the world. The home
