We are inclined to think, from our experiments, that the 

 Salmon will thrive during its minority in the tide-waters of 

 the Eastern Shore, but whether they will be able to reproduce 

 their kind in those rivers, is a matter that the future must 

 decide. We are inclined, however, to doubt the possibility 

 of their finding proper spawning grounds in those waters ; if 

 so, the supply must be kept up by artificial propagation, 

 which can readily be done, if their introduction into the 

 Potomac, Patuxent and Gunpowder becomes an established 

 success. 



On our first trip Vv'ith California Salmon to the rivers of the 

 Eastern Shore, carrying them in the ordinary transporting 

 cans, on the deck of the steamer Lookout, finding that they 

 were somewhat crowded and distressed, we commenced at 

 North Point to try the efi'ect of a change to salt water. 

 Setting apart a portion of the fish, and adding to these cans 

 the water of the Bay, little by little, until the water became 

 quite salt, to our surprise we found that the fish immediately 

 revived, and became much more active. We were able to 

 keep fish in the cans which had been supplied with the salt 

 water some days without changing, during all of which time 

 they appeared much more active than those which were kept 

 side by side with them in fresh water, which was constantly 

 agitated and freshened. 



A few hundred of these fish were brought back to Baltimore, 

 and shipped by rail to Oakland, transported thence to 

 Fort Pendleton, on the North Fork of the Potomac river, 

 without change of water, and when deposited in the river at 

 that point they were lively and in good condition. We after- 

 wards, (to give the experiment of the young Salmon being 

 able to live in salt water a better test, having deposited a 

 number of fish in the Choptank and Pocomoke rivers,) filled 

 the cans with salt water at the mouths of these rivers, and 

 transported this water to the Hatching House at Druid Hill 

 Park, where we placed it in two of the nursery tanks. We 

 then put about 10,000 young fish into these troughs on the
