asked the Minister of Agriculture the revenue derived from admission to the Royal Botanical Gardens, Kew, for the 12 months ended to the last convenient date?

The revenue for the period of 12 months ended the 30th April, 1930, was £3,816 4s. 7d. Of this amount, approximately £1,800 was derived from the penny admission fee during the period that it was in operation, namely, from 1st May to 4th August, 1929. This fee was abolished on the 5th August, 1929, and charges for admission are now made only on students' days—Tuesdays and Fridays.

Are any special facilities given to school children for educational purposes on these days?

Yes, in every possible way.
