290 HISTORY AND METHODS OF THE FISHERIES. 



" break" is the test of the fatness of the fish, and is the guide by which the inspectors cull them 

 into the different grades for market, provided always that they are of suitable size. Stringent 

 laws have in past years been enacted in most of the New England States to regulate the method 

 of inspecting mackerel, and the use of any artificial means to fatten them was for many years 

 strictly prohibited. The introduction of the mackerel plow, like that of many other inventions, 

 was the direct result of a need long felt by fishermen. Previous to its adoption it was the custom 

 for the fishermen to attempt to improve the looks of their fish by increasing the natural break with 

 their thumb-nails drawn along its entire length. This method was called " rubbing the mackerel." 

 Later, a few begau to use the back of the point of their bait-knives or splitting-knives for this pur- 

 pose, by degrees venturing to place the cut a little higher than where it naturally belonged. The 

 use of knives led to the introduction of plows, which soon came into general use, though the fish- 

 ermen at first felt some hesitation about revealing the fact that their fish had been plowed.* 



A comparatively poor mackerel would not open sufficiently in a natural way to pass for a No. 

 2, but the fishermen give them an inviting appearance to the buyer by the use of the plow, which 

 they handle with remarkable dexterity, running the blade longitudinally along each side of the 

 abdominal cavity with great swiftness, laying the sides of the fish open in such a manner that it 

 may pass for a No. 2, and, perhaps, if it is of large size, a fairly fat fish may be culled as a No. 1 

 mackerel. It is but fair to say here, that, since the general adoption of the mackerel plow as a 

 means of " fattening" the fish, the subject is so well understood by the dealers that they demand a 

 finer looking fish than formerly, and the consumer, therefore, actually gets as good an article as before, 

 and one that is much more attractive. This is especially the case when the size of the mackerel is 

 not sufficient to pass for the best quality, or No. 1. A fish whose length is 13 inches and "of suit- 

 able fatness" is required for a No. 1, but it is ea.sy to see that a fish of fine quality, though not ex- 

 ceeding 12 or 12 inches, is just as good for food, notwithstanding the fact that it must pass for a 

 lower grade and be sold for a much less price. For the past few years a very large portion of the 

 mackerel caught on our coast have been " undersized," that is, not long enough to pass for the best 

 quality, according to the inspection laws of New England ; nevertheless they are in all respects 

 quite as good as the larger and rarer grades. 



As previously stated, the fishermen no longer make a secret of using the plow, and during the 

 summer season, when the wharves on the eastern coast are filled with mackerel, the operators may 

 be seen in the open air busily rimming the fish almost as fast as they can pick them up and throw 

 them into another barrel. There are many styles of this type of knife, their patterns and designs 

 being as varied as the fancies of those who make them. They are, with but few exceptions, made 

 by the fishermen; some of them are exceedingly plain and rough, while others are artistically and 

 elaborately decorated, often with imaginary uncouth figures or with fancifully carved leaves, 

 wreaths, &c. 



There are several knives of this character deposited in the fisheries collection of the United 



* From a circular addressed to the masters and crews of mackerel vessels by Hon. James Barry, inspector-gen- 

 eral of pickled fish for Massachusetts, dated May 2, 1832, we quote the following in relation to the use of the mackerel 

 plow : " It is a mischievous error that fishermen have fallen into by suiting their fish too slack, as has been often the 

 case ; and another by using the plow, which has given to the fish a false appearance, and has been a source of morti- 

 fication to the fishermen, and they have in a great many instances I'onml fault with tho inspectors when the fault be- 

 longed to themselves in not taking care of the fish, which it was their duty to do, and which in many cases has been 

 a ruinous business to purchasers. By a law of the commonwealth the inspector is required to throw into an inferior 

 quality all mackerel which have been plowed, out, or mutilated for the purpose of deception. It can be of no advan- 

 tage to the fishermen, and I trust will never again be done." 



Capt. N. E. Atwood says that some of the fishermen made mackerel plows with "the ends tipped with pewter 

 and fine teeth on the edges so as to make the crease look rough, as though it were broken naturally; others had a 

 knife in the end which cut the mackerel smoothly."
