The State Fish Exhibit. 



The legislature at its last session made an appropriation of $8,000 in 

 order that the fish commissioners mi^ht make a creditable exhibit of 

 the piscatorial work accomplished. Preparations were immediately- 

 begun to carry out this work, and Col. John Gay, a former member of 

 the commission, was appointed manager. 



FisHEBiEs Building, Jackson Park, 

 Chicago, III., April ^6, 1893. 



The exhibit consists principally of live fish of the difi'erent varieties, 

 propagated by the fish commission of the state, together with many of 

 the lake fishes. It is made in aquavia constructed of iron and French 

 plate glass, the largest being six feet, three feet long, three feet wide 

 and three feet high, and so arranged that the fish can be seen to the 

 best advantage. The space allotted to the Pennsylvania State Fish 

 Commission in the Fisheries Building is one of the largest, 1,701 square 

 feet of kite-shape, running along the main hall, the entrance being at 

 the small end of the kite. At the entrance there is an arch twenty feet 

 in height, of rustic work made up of cedar and oak bark, trimmed with 

 laurel roots over which vines will run. At the centre of the arch the 

 keystone appears bearing the state coat of arms. Entering, the visitor 

 will see two pools containing a working model of the Rogers' patent 

 fishway practically illustrating the best known method of passing fish 

 over dams, in their movement up streams in search of suitable spawn- 

 ing grounds. These pools are supplied with water by a cascade which 

 tumbles down over artificial falls from the highest point of the roofing 

 over the aquavia. The work thus built up conforming to the apex of 

 the kite was a tunnel lined with oak bark and dotted with twisted roots 

 of laurel. The aquavia numbering twenty rest upon stout supports 

 covered with cork bark ; at the bottom there is a row of natural stone. 

 The tunnel being dark, the light from without showing through the 

 glass sides of the aquavia, and exposing what they contain to visitors 

 passing through the tunnel. 



On all sides of the rustic work beautiful green plants have been 

 found, and evergreens cover the entire top of the tunnel and present a 

 very fine appearance. Models of the hatchery buildings at AUentown, 

 -Corry and Erie, are near the main aisle and over them hang enlarged 

 photographic views of the several stations, the transportation car, and 

 photographs of the members of the commission. Fifteen beautifully
