In 1824, according to the following high scale of duties, viz., 1s. on West India, 1s. 6d. on East India, and 2s. 6d. on foreign, the Customs derived from coffee was £420,988; in the following year the rates were reduced one-half, and in the short space of three years the amount yielded had advanced to £440,245, an increase which steadily progressed (partly aided by the admission of the produce of British India at the low duty) until it reached £921,551 in 1840. These satisfactory results justified a further reduction of the duties in 1842 to 4d. on colonial and 8d. (and in the subsequent year to 6d.) on foreign, under which the revenue declined in 1844 to £681,616. In 1846 it had again reached to £756,838, and was gradually recovering itself, when this system of adulteration first began to extend itself generally, and since that time the revenue has rapidly declined under the _same scale of duties_ to £566,822 in 1850. In 1824 the quantity retained for home consumption was 8,262,943 lbs., which was augmented to 11,082,970 lbs. in the first year of the reduction of duty, and continued to exhibit an increase at a rate rather exceeding two million pounds per annum until 1830, when coffee would appear to have reached its limit of consumption without further stimulus, and remained stationary until the modification of duties allowing the admission of foreign coffee, _via_ the Cape, at the colonial rate, when it advanced from 23,295,046 lbs. in 1835, to 28,723,735 lbs. in 1840; and consequent upon a further reduction of duties in 1842, the elasticity of the trade experienced a still wider development, and an increase of nine million pounds is exhibited in the next five years. From that period, however, the general use of chicory has not only checked the progressive increase of this healthy demand, but an annual decline is observable to the extent of above six million pounds in 1850, as compared with 1847. On the 15th of April, 1851, with the view of partly remedying the grievance of the colonists on this head, the duties were equalized and reduced to 3d. The results are, however, far from satisfactory, either in a fiscal or commercial point of view. It is true that an increase in consumption, of one-and-a-quarter million pounds has taken place, but at the sacrifice of £121,000 of revenue. But this increase, it will be seen, has not exceeded 4¼ per cent., whilst there has been a diminution of 21½ per cent. in the revenue receipts. Upon investigation, moreover, it will be found that, notwithstanding the _total_ increase exhibited, there has been an actual falling off of 894,778 lbs. of colonial coffee in 1851; the items for last year are, however, much more favorable and encouraging for the planters. No reasonable cause can be assigned for this rapid and serious diminution in the consumption of coffee, except the notorious substitution of chicory and other substances.
