Some 20 head of heifers were grazed for over twelve months and sold at an average profit per head of £ll ss. These cattle are being replaced with 33 head of steers. Upper Wangamoa Valley.—lt has not been possible to carry out any work except the general supervision of the area, the cutting of firebreaks, and the destruction of pests, including 10 deer, 24 pigs, 12 goats, and 47 opossums. Research The Council's work has continued during the year, but has been restricted by initial difficulty of obtaining suitable areas. It is hoped that this important activity will progress by the acquisition of suitable areas in the North and South Islands. Educational and Publicity Work During the past year publicity has been carried per medium of bulletins, press articles, film strips, movie films, and agricultural show displays. During the year the Council published a further two bulletins: Bulletin 5: " Down to the Sea in Slips." Bulletin 7: " Fire! Public Enemy No. 1." Some 20,000 copies of the former and 60,000 copies of the latter were distributed directly to those people most interested through Catchment Boards,local bodies, Federated, Farmers, and Education Boards. Bulletin 6: " Willows and Poplars "is with the press, while " Glossary of Terms: Hydrologic and Associated Soil and River Engineering Terms" has been issued provisionally before final editing and publishing. The mobile cinema unit has completed the first circuit of screenings in New Zealand not only covering the eleven catchment districts, but to organized farmers' meetings in Otago, Waikato, Bay of Plenty, and Northland. Screenings were made regardless of local electric-power supply, as theunit had its own generating-plant, while daylight screenings at publicgatherings and agricultural shows were made on many occasions. Some 44,840' persons attended these screenings, as follows: Number of Attendailce . Screenings.

Copies of films made are supplied to the National Film Library and are thus available to the public from two sources. There are so many 16 mm. projectors variously owned, and New Zealand films are in such demand, that all copies available are in continuous circulation. Soil conservation displays at agricultural shows are catered for by two units—one in each Island. The main element in each display has been a duplicate model of a typical farm on rolling country, one model showing poor farm practices and evident erosion, and the other model showing the same country with soil conservation practices.
