The new tariff is based almost entirely on specific schedules; only in exceptional instances, such as in the case of drugs, are ad valorem duties imposed. There were many reductions from the former tariff, especially on articles of prime necessity, but in some cases the rate remained substantially the same, while in a few it was slightly increased, a tendency being observed to protect home industries. On the whole the revision made an average reduction of about 15 per cent as compared with the former tariff, but the new duties are scientifically distributed and after a year of commercial readjustment the revenue reached higher figures than ever before. Less than 6 per cent of the customs receipts are derived from export duties. Such duties are imposed on cacao and a number of other articles, but not on sugar or tobacco. The tax is not a large one, but the imposition of any export tax is deplored. Wars and crop conditions have had their influence on the customs receipts, but the figures continue satisfactory, as appears from the following table of collections since the establishment of the receivership: GROSS CUSTOMS COLLECTIONS First Modus Vivendi year, April 1, 1905, to March 31, 1906 .................................................... $2,502,154.31 Second Modus Vivendi year, April 1,1906, to March 31, 1907 .................................................... $3,181,763.48 Four months' period, April 1, 1907, to July 31, 1907 (termination of Modus Vivendi)...................... $1,161,426.61 First convention year, Aug. 1, 1907 to July 31, 1908 .................................................... $3,469,110.69 Second convention year, Aug. 1, 1908 to July 1909 .................................................... $3,359,389.71 Third convention year, Aug. 1, 1909 to July 1910 .................................................... $2,876,976.17 Fourth convention year, Aug. 1, 1910 to July 1911 .................................................... $3,433,738.92 Fifth convention year, Aug. 1, 1911 to July 1912 .................................................... $3,645,974.79 Sixth convention year, Aug. 1, 1912 to July 1913 .................................................... $4,109,294.12 Seventh convention year, Aug. 1, 1913 to July 1914 .................................................... $3,462,163.66 Five months' period, Aug. 1, 1914 to Dec. 31, 1914 .................................................... $1,209,555.54 Ninth fiscal period, Jan. 1, 1915 to Dec. 31, 1915 .................................................... $3,882,048.40 Tenth fiscal period, Jan. 1, 1916 to Dec. 31, 1916 ................................................... $4,035,355.43 Eleventh fiscal period, Jan. 1, 1917 to Dec. 31, 1917 ................................................... $5,329,574.20
