With underground drainage, a heavy fall of rain tends to leach out the excess of salts ; whereas on undrained, flat, clay lands the excess moisture has to escape by evaporation, and the secretion of surface salts is, therefore, increased. On an irrigation area, heavy manuring, or correct rotation of crops, is neces- sary.

Several profitable crops of straw- berries and cauliflowers could have been obtained, and many a milk cheque increased, by the practice of these methods during the past few months. A dressing of lime, in conjunction with di-ainage and watering, will convert many a sour swamp into a luxuriant fodder patch, and if the feed is not required immediately when grown, it can be easily converted into ensilage. The application of water by the furrow system followed by frequent cultivation, with provision for drainage and rotation of crops, are the neces- sary principles of "wet farming," which must be practised by all farmers on ..any large or small irrigation scheme to obtain profitable and permanent Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original New South Wales.
