The strength of prices of most agricultural raw materials in 1987 contrasts sharply with their weakness during 1985 and 1986 (Table 46 and Chart 6). As discussed in this section, prices of logs, natural rubber, cotton, wool, and hides all increased by large percentages in 1987. The tobacco market also appeared more active than for a number of years, but this change was not reflected in prices because of the persistence of large stocks. The markets for jute and sisal, however, remained weak, although some longer-term adjustments appear to be taking place.
