First, The herring-buss bounty seems too large.
From the commencement of the winter fishing 1771, to the end of the winter fishing 1781, the tonnage bounty upon the herring-buss fishery has been at thirty shillings the ton. During these eleven years, the whole number of barrels caught by the herring-buss fishery of Scotland amounted to 378,347. The herrings caught and cured at sea are called sea-sticks. In order to render them what are called merchantable herrings, it is necessary to repack them with an additional quantity of salt; and in this case, it is reckoned, that three barrels of sea-sticks are usually repacked into two barrels of merchantable herrings. The number of barrels of merchantable herrings, therefore, caught during these eleven years, will amount only, according to this account, to 252,231¼. During these eleven years, the tonnage bounties paid amounted to £155,463:11s. or 8s:2¼d. upon every barrel of sea-sticks, and to 12s:3¾d. upon every barrel of merchantable herrings.
The salt with which these herrings are cured is sometimes Scotch, and sometimes foreign salt; both which are delivered, free of all excise duty, to the fish-curers. The excise duty upon Scotch salt is at present 1s:6d., that upon foreign salt 10s. the bushel. A barrel of herrings is supposed to require about one bushel and one-fourth of a bushel foreign salt. Two bushels are the supposed average of Scotch salt. If the herrings are entered for exportation, no part of this duty is paid up; if entered for home consumption, whether the herrings were cured with foreign or with Scotch salt, only one shilling the barrel is paid up. It was the old Scotch duty upon a bushel of salt, the quantity which, at a low estimation, had been supposed necessary for curing a barrel of herrings. In Scotland, foreign salt is very little used for any other purpose but the curing of fish. But from the 5th April 1771 to the 5th April 1782, the quantity of foreign salt imported amounted to 936,974 bushels, at eighty-four pounds the bushel; the quantity of Scotch salt delivered from the works to the fish-curers, to no more than 168,226, at fifty-six pounds the bushel only. It would appear, therefore, that it is principally foreign salt that is used in the fisheries. Upon every barrel of herrings exported, there is, besides, a bounty of 2s:8d. and more than two-thirds of the buss-caught herrings are exported. Put all these things together, and you will find that, during these eleven years, every barrel of buss-caught herrings, cured with Scotch salt, when exported, has cost government 17s:11¾d.; and, when entered for home consumption, 14s:3¾d.; and that every barrel cured with foreign salt, when exported, has cost government £1:7:5¾d.; and, when entered for home consumption, £1:3:9¾d. The price of a barrel of good merchantable herrings runs from seventeen and eighteen to four and five-and-twenty shillings; about a guinea at an average. {See the accounts at the end of this Book.}
Secondly, The bounty to the white-herring fishery is a tonnage bounty, and is proportioned to the burden of the ship, not to her diligence or success in the fishery; and it has, I am afraid, been too common for the vessels to fit out for the sole purpose of catching, not the fish but the bounty. In the year 1759, when the bounty was at fifty shillings the ton, the whole buss fishery of Scotland brought in only four barrels of sea-sticks. In that year, each barrel of sea-sticks cost government, in bounties alone, £113:15s.; each barrel of merchantable herrings £159:7:6.
