the Itime among the fea-fifli : and I know inftances 
of its being caught in the harbour of Dantzig, be- 
tween that city and a little town called Hela ; which 
The fmelt or fparling (Salmo Eperlanus Linnaei) never comes 
up our rivers, but for a fiiort time ; and then does not penetrate 
much further than where the water continues to be brackifti. 
I have, however, been informed by Sir Francis Barnard (the 
late Governor of New England) that in a large pool which he 
rented net far from Borton, and which had not the leaft com- 
munication with the Tea, feveral of thefe fiflr, originally introduced 
from the fait water, had lived many years, and were, to all ap- 
pearance, very healthy. 
I have alfo the following welUattefted fa£t with regard to the 
common grey mullet, which it is believed was never before'taken 
in frelh water. 
Mr. Kymer hath made, near Kidwelly in Carmarthenfhire, a 
communication between his collieries and an arm of the fea, by 
means of a canak 
Before this canal was compleated, the fait water filled it at 
every tide, and feveral mullets were by this means introduced. 
For thefe three or four years, the fea hath been entirely ex- 
cluded i and the canal, from the conftant influx of frefli water, 
hath ceafed to bfetbrackifli for more than two years. 
The mullets, however, continue to live in this canal ; though 
Mr, Kymer informs me, they do not look in fo good condition, 
as w'hen frefh from the fea. 
We are fo much in the dark about the natural hiftoryof fifh, 
particularly thofe of the fait water, that it is to be wifhed fea 
• j ftews were made on fome of our coafts, as I am told is very com- 
monly pradifed in North America, and for a very trifling ex- 
pence. 
Nothing more is requifite, than either to find or dig a proper 
cavity, perhaps a yard below the low water mark, at fpring tides, 
from which the fea fhould be excluded, exceprt at a narrow 
entrance, where large fiones fliould be piled from the beach to 
above the high water mark. 
Through luch an inlet, theftew would be every twelve hours, 
fiipplied with frtfh fait water, at the fame time that the fijh would 
not be able to make their cfcape.,
