If there is little hope of a reduction of the railway tariffs, there is still less chance, we think, of any reduction of the town-duties. They are far too profitable to the city funds. The revenue derived by the city of Paris from the sale of fish amounted, in 1858, to 894,214 francs; in 1859, to 928,925; and in 1860 it increased to 1,027,920 francs. This sum, however, only includes the dues levied upon fish carried to the market. There is a separate and distinct duty upon fish which arrive directly by railway to the consumer. In this case fine fresh fish are subjected to a duty of 60 francs the 100 kilogrammes; common fish, 15 francs; ordinary oysters, 5 francs; and Ostend oysters, 15 francs per 100 kilogrammes. The exact revenue accruing to the city from this source embraces these two duties; and in estimating the full amount that the merchant must pay for bringing fish into the town and selling it in the market, we must add to these dues the expense of cartage, railway fare, the double tithe of war, and the fees to the crier. From the official records of the market sales, we find that for six years there has been little difference in the price of fish. The tables of 1852 and 1862 show that mussels, shrimps, mullets, and salmon, are at the same price; lobsters, sprats, turbot, and shad, are a little less; and mackerel, whiting, monkfish, sardines, sole, tunny, trout, barbel, and flounder, are slightly raised. The prices vary so little that any increase in the revenue must arise from an increased quantity being brought into the market. Oysters, however, have increased greatly in price, although the quantity has diminished. [Illustration: BILLINGSGATE.]
