In the previous season vetches were grown in these pots and afterwards dug in as green manur- ing. Suppose then that we adopt this plan of green manuring with peas or beans, we need only manure the ground with superphos- phate and potash salt, sow the peas or beans, and plough them in at blossoming time. Our expenses would then run as follows:— IJ cwt. concentrated superphosphate at 13s. 4^d., £1 3s. ; 1^ cwt. potash salt, at 12s., 13s. 6d.; peas or bean seed, 4s.; total, £2 Os. lid. This is one of the cheapest and most beneficial methods of manuring the soil, and is especially to be recom- mended at distances from Melbourne, where the freight on manure is heavy. On the whole, it may be said that manure prices in Victoria are low as compared with other countries, and the wide-awake cultivator who looks well into the manure market can make some very advantageous purchases. This cheapness of manure is not owing to the great quantity of manure in the market, but to the small demand for it. A great deal of manure is exported from Victoria; it may be that more is exported than is used within the colony. This is not because Victorian soils do not need manure. There is no country in the world that is covered with rich first- class soils
