Excerpt from Transactions of the American Society of Civil Engineers, Vol. 52: Instituted 1852; June, 1904 Case 2.-a group of five furrows. Maximum length, about 7 miles. Average combined flow near fields, during three summer months, cu. Ft. Per second, or 17 000 000 cu. Ft. For the whole summer, exclusive of the night flow which is seldom used. Waters 718' acres, all the year, and an additional 350 acres in the winter during good seasons. Flow of river, Observed during one summer: minimum, cu. Ft. Per second; maximum, 1 378 cu. Ft. Per second. Fall of river, about 45 ft. Per mile. Greatest known flood, about 5200 cu. Ft. Per second. Catchment area, 68 sq. Miles. Average annual rainfall at source, ins, and, in vicinity of fields, ins. Seasonal rainfall: spring, ins.; summer, ins.; autumn, ins.; winter, in. Lucerne is largely grown as food for ostriches; other crops are tobacco, wheat, barley, maize, beans, vines and fruits. There is considerable irrigation from springs, or fountains, as they are called, but, unfortunately, there are no statistics of any kind available, and even in the case of furrows there is only a very partial record which refers mostly to those used for village water supplies. The finding and opening up of two of these fountains will now be described, as they are rather interesting. In both cases the sites were inspected and the details noted and checked on the ground, as far as possible. Case 3. - A farmer purchased a farm of 4 000 acres on which there was no water. After a time he noticed signs of moisture in a hollow, which he therefore plowed over regularly so as to assist the summer thunderstorms in forming a sluit (stream) and Opening Up the ground. This resulted in the rock being laid bare, eventually, at a depth of 20 ft. From the surface, and, as the flow of water was then stronger, and a trap dike ran across the country just below, he decided to have bores put down.
