rubber tubes and glass connections into the jars, and out of 

 jars by an over-flow glass tube. The eggs are kept in con- 

 stant motion by the flow of water, and thus prevented from 

 matting together, and dead eggs are carried off by the over- 

 flow. 



As soon as the eggs show signs of hatching, a large glass 

 aquarium is placed on the table, and the over-flow pipe led 

 into it, so that as the fry come out they are taken out of the 

 hatching jars through the over-flow into the aquarium and 

 placed in a tank having a constant stream of fresh water run- 

 ning through it. The fry are retained in this box until called 

 for for shipment or put overboard. 



Capt. Piatt stated that the process was quite simple, the 

 principal thing being attention to the supply of fresh water, 

 and cleanliness of the eggs, the McDonald jars being so well 

 and carefully constructed that this end was readily attained.

 large banqueting pavilion of Thompson's hotel. Mr. A. M. 

 Spangler, President of the Anglers' Association, presided. 



After partaking bountifully of that luxury of world wide 

 reputation, " Glo'ster planked shad," and of the salmon which 

 had been caught a day or two before in the Delaware River, 

 which was pronounced by all who partook of it fully equal to 

 the best " Kennebec," the company listened to brief speeches 

 by Dr. Hudson, Mr. Eugene Blackford, Prof. Leidy, Fred 

 Mather and Dr. Levick, but the speech making was cut short 

 by the announcement that the great shad seine, a 'mile and a 

 quarter in length, was being drawn, and that those who de- 

 sired to witness the haul would have to leave. Nearly the 

 entire company hurried to the shore, and with great interest 

 watched the proceeding. In order to gratify the visitors a 

 second haul was immediately made, after which the party re- 

 embarked on the steamer and returned to the city. The
