Chart XIV. Wholesale prices of iron, kerosene, etc., New York, 1867-1896. Page 106.
_Prices of iron, kerosene, etc., 1867 to 1896_
_Description and Explanation._--This chart gives the prices from year to year for steel rails, bar iron, pig iron and nails in the New York market, each dot indicating the average for the year. The average prices for the corresponding years for refined kerosene are also shown. No. 1 gives prices per ton of steel rails, into which enters all the influence of the improved methods of manufacture. No. 2 represents the prices of bar iron per ton, less affected by improvements but influenced by the substitution of steel. No. 3 gives the prices of nails per thousand pounds. For comparison with the other prices of iron, the prices of nails must be doubled. All will realize the immense improvements made in the manufacture of nails. No. 4 gives the prices per ton of pig iron. It is evident that all these forms of iron and steel have stood in the market under the same general influences, with slight modifications from special characteristics of production or use. No. 5 gives the average price in each year for one hundred gallons of refined kerosene oil. The price per gallon can be found by reading the figures as cents instead of dollars. In the same way the price of ten pounds of nails can be found. It should be said, however, that all these prices are the wholesale prices, retail prices being subject to local influences, sometimes even to custom, which prevents their adhering closely to the prices in larger markets.
_Even monopoly affected._--These articles have been chosen as illustrating the essential law of prices even under the advance of combination of capital upon an enormous scale. The iron industries and the Standard Oil Company come nearest, perhaps, to fulfilling the conditions of monopoly found anywhere. Yet the actual effect of improved methods in great combinations is seen to have reached the mass of the people in spite of any tendency to sustain prices by combination. A line, No. 6, indicating the general trend of wages for farm hands in the North, is added to more clearly indicate the distribution of welfare through such improvements in method. For still other purposes, the fluctuating price of silver bullion is shown in line No. 7.
