— 92 — 100 plants, or a sample row, in each plot are individually and periodically examined for a distinct record, further warrant the continued adoption of the current system. The chequer-board system is of course inapplicable, for practical reasons, to Times of Planting, Duty of Water and Cultivation Experiments.

The results of a superimposed experiment in the topping of cotton was graphically illustrated last season. The times of planting hosh was divided longitudinally, so that cotton of every age was topped simultaneously. The result was most satisfactory. In every instance the topped cotton yielded more than the untreated. The difference is not so marked in the older plots, and the best time to top was ascertained to be when the plant is from seven to ten weeks old. (See Chart No. 1.)

Modules.—Two " Gibb's Patent Modules " are in use for the Duty of Water Experiment—one on each section of the farm. These modules deliver a uniform flow of water despite a varying head in the supply canal, and thus render the control of the various amounts required by each plot very simple ; e.g., as the module delivers 208"3 cubic metres of water per hour, the full stream of water has to be turned on to a feddan for 1 hour 55 minutes to supply it with 400 cubic metres. These modules represent the only reliable, self-regulating water metre on the market, and are invaluable where a constant and known discharge of water has to be maintained for a given time.

Cultivation.—The ordinary cultivation employed in connection with all crops on the farm consists of the following operations : I. Ploughing : This is done with an " Oliver " mould-board plough, working at a depth of 12 cm. It has been found advisable to flood land before ploughing, as not only can the work be done faster, but a better tilth results. The land is then cross-ploughed. Whenever time permits a Eansom's disc plough is substituted for the mould-boar(J plough, especially after lubia, as it turns the stubble under much more effectively.

II. Rolling or Disc Harrowing : This is necessary to crush the clods which are invariably turned up during ploughing. The disc harrow is used where clods are not heavy and hard.

III. Levelling : Uneven land is levelled after rolling and a little extra earth is drawn to the lines of the distributory gadwels. For wheat, levelling and the formation of hods proceeds simultaneously.

IV. Ridging : Ridges one metre apart are thrown up for cotton and lubia.
