Most of the fish packed on Lake Huron, and rivers St. Clair and Detroit, find their way into the Ohio market. The trade with that State has rapidly increased, but in its early stages it had some difficulties to contend with, to one of which we will briefly allude. Some twelve or fourteen years ago, a large quantity of fish, not less than 8,000 to 10,000 barrels, which had been caught in Lake Superior, were in the possession of a single dealer, who had them stored in the large warehouse recently torn down at the Detroit and Milwaukee Railway depot. He had opportunities to dispose of them at $8 per barrel, but refused to sell them for less than $10, and the result was that they were kept so long that many of them spoiled. They were complained of as a nuisance, and 1,500 barrels were turned out into the river at one time. Part of the lot was, however, sent to Ohio, and the effect was, for a time, extremely prejudicial to our trade, requiring a great deal of explanation before the Cincinnati dealers could be again induced to stand in the position of customers. But when confidence once more became fairly restored, the circumstance seemed to have the effect to precipitate the trade between the two cities. At least it grew rapidly from that day, our neighbors purchasing freely of our staple articles and sending us sugar and molasses in return. Thus, as in Samson's time, honey was gathered from the carcass of the dead lion. Ohio has become a very large consumer of our fish, and her influence is being extended rapidly into Indiana.

The habits of fish are as interesting as anything in the animal economy, constituting a beautiful study for the lover of nature; but this branch does not come within the scope of our article, and we must content ourselves with a brief description of the principal varieties, particularly such as are held in highest repute for packing, with such statistics as we have been able to procure.

Whitefish are more highly prized than any other kind found in our waters, being decidedly the most delicious in a fresh state, and when packed command a higher price than any other by $1 per bbl. They are found in the Straits and all the Lakes. They spawn in the fall, in the Straits, and in shoals and on reefs about the Lakes. They are caught in seines, gill nets, trap nets, and with spears; never with hooks. Those found in Detroit river come up from Lake Erie regularly in the fall to deposit their spawn. They were found in our lakes and rivers in vast quantities when the white men first visited their shores. They constituted, with other kinds, the principal food of the white and Indian voyagers as they coasted around the lakes, and were invaluable to the first settlers of the country, who, perhaps in some cases, but for the assistance they afforded, would have been compelled to relinquish their settlements. They could catch a supply at any time, and they then had an unfailing resort when their crops failed. Whitefish were a great favorite with the Indians. They would give many times their weight in trout or any other species in exchange for them. It is said that a person can subsist longer upon them than upon any other kind.

Their ordinary weight is from 3 to 5 lbs, length 15 inches, though some have been caught weighing not less than 18 lbs. They are a beautiful fish, and when first taken out of the water and struggle and flounder in the sun, they exhibit all the colors of the rainbow, but they soon expire, and when dead they are of a delicate white color. The trout, pike, and muscalonge devour them without mercy. Some of these voracious kinds have been caught with the remains of six white-fish in them.

The Detroit River white-fish are more juicy and better flavored than those caught in the upper lakes, probably from the fact that they feed on more delicate food, but those found in Lake Superior surpass all others in size. They were once so numerous that eight thousand were taken at a single haul. At present a haul of one or two thousand is thought a very good one. In all the rivers they are growing scarce very gradually, but surely. The ratio of decrease cannot be arrived at with any degree of precision. A few years ago they were mostly taken with gill nets, and when they fell of in one place, a corresponding increase would be found in another. Now they are taken with trap nets along the shore. The trap nets are a decided advantage over gill nets. They allow the fish to be kept alive, and they are taken out at leisure; they are therefore of better quality.

Pickerel are also held in high esteem. They are good either fresh, or salted and dried, and for packing, rank next in value to white, although held nominally at the same price as trout when packed. They generally run up the rivers and lakes in the spring to spawn, where they are caught in considerable numbers. Average weight, 2 lbs; large, 20 lbs; common length, 15 inches.

Lake or Mackinaw trout are as voracious as pike. They are chiefly caught on Lake Huron with gill nets and hooks. Saginaw Bay appears to be a favorite resort with them. Some winters large quantities are caught in the Bay through the ice, with a decoy fish and spear. They spawn in the fall, generally in the bays and inlets. Average weight 5 lbs; large 75 lbs.

Siscowits are mostly found in Lake Superior, and are preferred by some to any other kind. They are of the trout family, and for fat are unequaled; they are mostly taken in gill nets. They spawn in the fall, and are very superior for packing. They are also of some value for their oil. Common weight 4 pounds, length 16 inches.

Large herrings are very good fish, found only in the straits and large lakes. They spawn in the fall; but few are caught. Average weight 1-¾ pounds; common length 10 inches.

In addition to the above the muskelonge—a large and delicious variety—black and white bass, rock bass, perch, sturgeon, and at least twenty other kinds, abound in our waters; a minute description of which we are compelled to forego. Whitefish are taken both spring and fall, chiefly the latter; spring is the season for pickerel; trout are taken at all seasons.
