—As has already been noted, the Pacific salmon belong to a different genus from the common Atlantic salmon,—Salmo salar. There is a very close resemblance between the two genera, and the common name “salmon” is applied to the individuals of each. The Atlantic salmon is a fish which has been known from the earliest time. The Roman people became acquainted with it in the early history of the Republic, and especially when they conquered Gaul and Britain. It is found distributed over the whole North Atlantic coast, but especially the northern portion from Massachusetts northward. The salmon extends, as far as observations have been made, beyond even the Arctic circle, and the same species is found upon the western and northern shores of Europe. The salmon enters the St. Lawrence and has been found as far up as Niagara Falls. Our principal fisheries for this species are in Maine and in Canada, Nova Scotia, and New Brunswick. They do not extend southward beyond the Delaware and have rarely been found in that river. The shad and salmon were particularly abundant in early colonial days. The shad were so abundant that they were not regarded as useful for food purposes, but their value as a fertilizer was taught to the whites by the Indians. Salmon, apparently, were equally abundant, and it was considered an affront to offer salmon more than twice a week even to servants. In this respect they were on the same plane as the diamond back terrapin and canvas back duck, which were so abundant, in those days, that they were a drug on the market. The salmon enters the fresh-water streams for the purpose of spawning. The eggs are largely laid late in the fall, and in that case do not hatch until the next spring. The Atlantic salmon often reach a very large size. Individuals have been known to weigh from 40 to even 80 pounds. The average weight of the salmon taken in Maine waters is about 10 pounds each. Another valued specimen of salmon is known as the Sebago salmon (Salmo sebago), from the lake in which it occurs. It is a fresh-water fish, having been doubtless landlocked in some way after originally entering from the sea. Still a third species is the famous ouananiche (Salmo ouananiche), inhabiting the waters of the Lake St. John region north of Quebec.

The above data show a striking difference in the composition of the edible portions of Pacific and Atlantic salmon. This difference is shown chiefly in the relative proportion of fat. In the Pacific salmon the fat approaches in quantity the protein, while in the Atlantic salmon the protein is much greater than the fat. The Atlantic salmon is used chiefly in the fresh state for two reasons, first, because the catch is very much smaller than that of the Pacific species while the markets are very much more numerous and very much larger; second, because it is commercially more profitable to dealers in the fresh state. In Europe and Scotland the salmon is constantly used in a fresh state during the whole of the summer and a dinner is scarcely considered complete without it. It is also very commonly used at luncheon. It is generally eaten cold and offers a food product of high palatability and great nutritive value in so far as the protein is concerned. Eaten with plenty of potato, as it usually is, it forms a reasonably well-balanced ration. The American visitor who is not used to eating salmon every day is likely to find its constant occurrence upon the English table in the summer to be a bit trying to his taste.
Sardines.
—The sardine belongs to the herring family—in fact small herring along the coast of Maine are put up as sardines. The sardines are very closely related to the herrings, but there are rather important differences. The European sardine, which is known as the sardine, is the Sardinia pilcharda, and does not occur on the coast of the United States. The species existing on the Pacific coast is known as the California sardine (Sardinia cærulea). It is quite abundant on the California coast and spawns in the open sea. It resembles very strongly the European sardine, but has no teeth. The Spanish sardine (Sardinia pseudohispanica) is found rather abundantly in Cuba and is often carried northward in the Gulf Stream as far as Woods Hole or Cape Cod. It is about 8 inches in length and of high food value, resembling very closely the European sardine. There has been a good deal of discussion as to whether or not small herring which are packed as sardines in the United States should be allowed, under the food laws of the various states and of the United States, to be sold by that name. The answer to this is that any deception in the label should be avoided. The herring, however, belongs to the same genus as the true sardine, and, differing from it only in the variation of species, may have some right to the name. The true ethical principles of trade, however, would require that they should be named Maine sardines or herring sardines and not bear the name simply sardines, which is reserved exclusively for the species Sardinia pilcharda.
