Note 20 — Chapter XIII · NEW SOUTH WALES.

I do not mean to say, that irrigating an acre of wheat or maize would double the yield of grain, but that double the number of acres now under the plough would in a few years, after the irrigating system had been fairly tried and found to answer, be brought under cultivation. In the neighbourhood of Bathurst, and in many other parts of the Colony where rain is very uncertain, there are thousands of acres of alluvial land lying waste, which, upon my plan, would yield tens of thousands of bushels of wheat and maize.
