192 AMERICAN FISHES. 
sionally taken on trolling tackle in use in blue-fishing, but is never, so far 
as I am aware, a definite object of pursuit. 
Genio C. Scott wrote, in 1875: ‘‘ My experience in trolling for Spanish 
Mackerel off the inlets of Fire Island has convinced me that the fish is as 
numerous as the blue-fish, and more so than the striped bass, at certain 
seasons, and is found a little farther seaward than either of those fishes.’’ 
‘Every year the shoals of Spanish Mackerel become more and more 
numerous, and more are taken, but never in sufficient numbers to reduce 
the average price below sixty cents per pound. The shoals which I saw 
when last trolling for them would have formed an area nearly five miles 
square, and still the most successful boat did not take more than a dozen 
in three days. They will not bite freely at any artificial lure, and though 
numbers came near leaping on the deck of our yacht, they treated our 
lures with an indifference which savored of perverseness.”’ 
Trolling seems to be more productive in the Gulf of Mexico than far- 
ther north. 
Mr. Thaddeus Norris states that in the Gulf of Mexico, they are some- 
times taken by hook and line, with shrimp-bait, at the end of the long 
piers where the steamers land in Mobile and New Orleans. 
THE SILVER CERO. 
The early chronicles of the colonies seem to contain no references to 
the Spanish Mackerel under its present name, but it seems certain that this 
fish was the speckled hound-fish, spoken of in that renowned work, ‘‘ New 
England’s Rarities Discovered in Birds, Beasts, Fishes, Serpents and Plants 
of that country, etc., by John Josselyn, Gent,’’ published in 1672. 
Josselyn wrote of ‘‘ Blew-fish or hound-fish, two kinds, speckled hound- 
fish, called horse-fish.’" The blue-hound-fish can be nothing else than the 
common blue-fish of our coast (Pomatomus saliatrix), and no species in 
the western Atlantic, other than our Spanish Mackerel, sufficiently resem- 
bles the blue-fish to warrant the use of sosimilaraname. Mitchill referred
