asked the Minister of Land and Natural Resources what price increases have been made each year in the last five years of the 1/2500 scale ordnance sheets; and how many have been purchased each year.

The prices of the National Grid 1km and 2km 1/2500 sheets were increased from 7s. and 10s. respectively to 8s. 6d. and 12s. 6d. on 1st January, 1964 and to 16s. and 24s. on 1st April, 1966. There has been no change in the price of the old County 1/2500 sheets. The estimated sales of these sheets are as follows: 1961–62—179,000; 1962–63—183,000; 1963–64—189,000; 1964–65—256,000; 1965–66—272,000.
