REPORT OF 1959 DRAIN TILE SALES Donald R. Sisson, Extension Agricultural Engineer
Twenty-five drain tile manufacturers reported sales of nearly 40 million lineal feet of drain tile in Indiana during 1959. Table 1 shows the 1959 drain tile sa.les as reported by 10 cL^r and 15 concrete drain tile manufacturers. In addition to these 25 plants, there were eight or ten others in operation that produced mostly minor quantities—probably enough, however, to bring the total sales to more than 40 million lineal feet. This summary does not include drain tile shipped into Indiana by out-of-state manufacturers. However, some of the tile listed by Indiana manufacturers may have been sold in other states.

Little Change Compared to 1958
Table 2 shows a comparison of drain tile sales during the years 1957, 1958 and V59. Both clay and concrete drain tile sales greatly increased from 1957 to 1958, resulting in an overall increase of 21 percent. However, clay tile sales showed practically no change from 1958 to 1959, and concrete tile showed an increase of 4.7 percent. The result was an overall increase of only 0.8 percent.
Clay drain tile has accounted for more than 80 percent of the drain tile sales °r each of these three years. However, there is a slight trend showing that con-^•rote tile manufacturers are increasing their proportion of total sales. Concrete lie accounted for 15.8, 17.5 and 18.2 percent of total sales for the years 1957,
, and 1959, respectively.
