56 Fish, Fishing and Fisheries of Pennsylvania. 



necessary to place the troughs almost on the ground so that the work 

 of attending to them was anything but pleasant. The water which 

 supplied them was brought from the spring to the house by means of a 

 six-inch iron pipe. Thence it flowed through a trough running the 

 entire length of the building ; was cleansed by a number of flannel 

 screens, placed at intervals through the boxes, and fed into the hatch- 

 ing troughs by iron spiggots an inch in diameter. 



While looking about for a site for the hatchery, the commissioners 

 were also on the look-out for a suitable man to superintend the opera- 

 tion of hatching the ova of such fish eggs as might come into their 

 hands. On the recommendation of Mr. Howard I. Eeeder, Mr. John 

 P. Creveling was appointed to that position, and he has since remained, 

 and by his skill in his chosen calling, his strict attention to his duties, 

 and his devotion to the interests of fish culture, he has won for himself 

 the respect not only of the Fish Commissioners of the state, but of all 

 those who have been brought into contact with him. 



John P. Creveling was born near Bethlehem, New Jersey, and his 

 father's farm was separated from that of the genial and widely known 

 angler and fish culturist, "Thad Norris," only by the Muscanetcongal 

 creek. The buildings of Mr. Norris and of Mr. Creveling were so close 

 together, that their owners could readily converse with one another with- 

 out stepping out doors. Mr. Norris took a great fancy to the boy 

 Creveling, and initiated him into many of the mysteries of his gentle 

 art, and when he entered the work of fish culture at Troutdale, New 

 Jersey, took the lad into his employ. Here Mr. Creveling laid the 

 ground work of his knowledge of fish culture. One year after Mr. Non-is 

 sold out his fish hatching establishment to Dr. J. H. Slack, one of the 

 Fish Commissioners of New Jersey, and this sale Mr. Norris said at the 

 time, was made on condition that Mr. Creveling remained with the new 

 purchaser. This he did for four years. At the end of that period he 

 entered the employment of the Pennsylvania commission. 



As soon as the hatching house on Donegal creek, near Marietta, was 

 completed the work of hatching eggs was begun. The first species put 

 in the troughs were one hundred and fifty thousand eggs of the Cali- 

 fornia salmon. These had been received from the United States commis- 

 sion, but owing to several warm days, to the heat of which they were 

 exposed during tlieir journey, they arrived ia such a poor condition, 

 that it was only possible to save and hatch from them one thousand fish. 

 These were set at liberty in one of the tributaries of the Susquehanna. 



About the same time the commissioners purchased from Mr. Seth 

 Green, the superintendent of the hatching house of the State of New 

 York, one hundred thousand eggs of the salmon trout. These eggs 

 were conveyed, with little or no loss, from near Bochester under the per- 

 sonal supervision of Mr. Creveling, and a large percentage were success- 

 fully incubated and the fry placed in the waters of the western part of 

 the state in the following spring.
